Toothpaste ingredients - what is toothpaste made of

What is toothpaste made of?

Such a simple question, yet the answer is a long one. Many off-the-shelf toothpastes contain a plethora of ingredients.

But it’s a good idea to understand exactly what you are putting into your mouth on a daily basis and why. There are good cases for and against some of the most common ingredients.

In this guide, we look at those common ingredients: what’s natural, what’s needed and what’s controversial.

Before we dive into the individual ingredients, we’ll cover a few key topics when it comes to assessing your toothpaste.

Toothpaste: what’s it actually for?

The primary role of toothpaste is to act as an abrasive by removing plaque around teeth and the gum line. This process is absolutely essential in avoiding gum disease and tooth decay problems —  painful conditions that can lead to tooth loss.

The secondary function of most conventional toothpastes is the protection of teeth by the addition of fluoride.

Pastes and gels contain a number of active ingredients.  One such ingredient is fluoride, which acts to help kill bacteria and, more importantly, helps the surface of the tooth recalcify, when early decay has occurred.

Toothpastes are usually made up of abrasives, fluorides, foaming agents (Sodium Laureth/Lauryl Sulphate), detergents, flavorings and anti-bacterial agents. The problem is that some of the chemicals used are potentially harmful, as we discuss in more detail below.

It’s not a superman

A number of dental professionals have stepped forward to explain that toothpaste alone, plays a small role in our oral health care, and that a greater emphasis should be placed on thorough brushing and flossing.

In other words, the techniques we use to physically remove the bacteria are just as important, if not more so, in the prevention of gum disease and dental decay.

The message is clear: we can’t look to toothpaste to assume the superman role of protecting our teeth. And some believe we should simplify toothpaste as much as possible.

Despite the numerous claims manufacturers make (tartar protection, whitening, fluoride-free, extra-fluoride), toothpaste is merely an adjunct to a meticulous oral care regime.

As important as toothpaste itself is, knowing how to brush your teeth properly, along with other activities like flossing, all have a very important role.

Recent Scrutiny

The exact chemical content of popular toothpastes has been made the subject of scrutiny in recent years.

It has emerged that some components are potentially harmful, while some additives – namely plastic microbeads – are needlessly present as decoration. Although, it should be noted microbeads have now been banned in toothpaste within the USA.

While all chemicals are regulated, tested and monitored, what is disconcerting is that companies are not obliged by law to state exactly which ingredients are used within products. So while some may be listed, there is no law to enforce that all of them are.

While the big companies are not using anything in their pastes that are known to be toxic, for some, it’s the lack of transparency that causes concern.

This has led to a rise in popularity for ‘natural’ toothpastes, and DIY toothpastes made at home.

Do your own research

What we wish to emphasize within this article is the need for you to do your own research.

With some toothpaste ingredients, their level of safety or harmfulness is disputed among scientists and medical professionals. Often there is no definitive right or wrong answer.

It is not our position to comment on the safety of ingredients and explicitly say you should or should not use particular ingredients.

Our role is to present the different arguments and to draw your attention to existing discussions and evidence so that you can make your own decision on which ingredients you are happy to use.

We’ve also included lists of toothpastes that do not contain certain ingredients in case you would rather not use them.

Take a critical approach to manufacturer statements

It’s important to take a critical approach to marketing messages and manufacturer statements in any industry, but especially so when it comes to cosmetics that can contain a mixture of chemicals.

Just because a manufacturer regards something as safe, it doesn’t mean you should blindly follow it.

Taking the ingredient polyethylene (which is used to manufacture plastic microbeads) as an example, Proctor & Gamble, the parent company of Oral-B and Crest, did once state (before they were banned) on its ingredients page that ‘microbeads are safe for people and polyethylene is approved for use in some foods by the FDA.’

Statement about microbeads taken from P&G website prior to the microbead ban.

Given the evidence of microbeads being embedded in people’s gums (which we talk about in more detail below), to simply state that they are ‘safe’ is somewhat misleading. P&G uses the statement to justify the past usage of microbeads (they have now been phased out and are no longer used in the USA). But the fact is, they were decorative in the first place, and harmful to the environment. To simply declare them as ‘safe’ to cover past action shows a disregard for what’s taken place.

Furthermore, to dismiss the environmental argument against having microbeads in cosmetic products, the page states: ‘The science to date shows the breakdown of larger plastics to be the primary source of plastics in the ocean, not microbeads.’

One of the stats that came up in the recent UK parliamentary debate on the microbead ban was that: ‘it is estimated that 86 tonnes of microplastics are released into the environment each year in the UK from facial exfoliators alone’.

That’s a lot of plastic!

So yes, perhaps the larger plastics are the ‘primary source’, but why does that mean we should not worry about smaller contributors like microbeads? They are still contributing, they are still harmful to the environment, and their inclusion in cosmetic products is / was far from necessary.

For us, pages like this with their over-simplified, self-serving statements emphasize how important it is to do your own research and make your own decisions.

A closer look at the individual ingredients

In this section, we’ll look at the most common components found in toothpaste, as well as some of the arguments that have been presented for and against them.

Throughout this article, we refer to the U.S Food & Drug Administration (FDA) because it has a wealth of information listed on its site about individual chemicals.

It is also worth noting that regulations will differ between the US and other countries of the world. Each country can have different legislation and regulation on what and what is not allowed and these goalposts do change over time.

Abrasives

People have been mixing substances together throughout history, as far back as Egyptian times, to clean teeth. Abrasives are used to cause a small amount of abrasion. Technically speaking, abrasion is the use of physical forces to remove substances.

Some people may also describe this erosion. However, erosion is different in that erosion is the use of acids to remove substances.

In toothpaste, small particles act as an exfoliant to target the biofilm on teeth. Abrasive particles nowadays are made from aluminum hydroxide, hydrated silica, hydrated alumina, calcium carbonate, calcium hydrogen phosphates and hydroxyapatite.

A Relative Dentin Abrasivity index is used to measure how abrasive toothpaste is. Toothpaste with a higher abrasive index has been linked to a greater incidence of abrasive wear on teeth. However, hard bristles and incorrect brushing technique, as well as high levels of acid in modern diets, is a greater cause of tooth wear.

Symptoms of tooth wear, be they abrasion or erosion, include sensitive teeth and receding gums. Tooth wear can also form “holes” on the side of the tooth and may lead to teeth picking up staining more easily.

Whilst too much abrasion can cause problems, without an abrasive you won’t achieve a comprehensive clean.

Tartar control and whitening toothpastes are known to be slightly more abrasive. If you are a smoker, using smoker’s abrasive toothpaste will be more effective at removing staining compared to other brands, but also can cause more damage.

Whilst abrasive toothpastes cause damage if used long term, they have a role in removing staining at home if used occasionally.

Non-abrasive toothpaste brands

Some of the most abrasive toothpastes on the market include Colgate Tartar Control and Crest Multicare Whitening. Arm and Hammer is also abrasive, and will cause damage if used regularly.

Tooth abrasion can be avoided by using low-abrasive toothpastes. Freysmiles Orthodontics have published a list of best-selling toothpaste alongside their abrasive index. Anything below 70-80 RDA on the index is considered low-abrasive.

Colgate Fluoride Toothpaste box

One of the most readily available toothpastes on the list is Colgate Regular, but there are plenty to choose from. Have a look through the list yourself here.

A less abrasive toothpaste is less likely to remove the outermost surface of the tooth, enamel. But beware that toothbrushing technique is also very important. If you are concerned you should consider your brushing technique too.

Fluorides

Fluoride is an additive used to remineralize teeth, which helps strengthen dental enamel.

Dental decay is essentially the softening of the enamel. Bacteria in the mouth use the sugars and carbohydrates we eat to produce energy. Their waste product is acid.

The acid produced by bacteria removes the calcium and other minerals from the enamel. This process is called demineralization or decalcification. In the early stages these areas may appear as white spots, and can even pick up stains to become brown spots.

Demineralization is actually reversible. But decay occurs if the rate of demineralization is faster than the rate of remineralization

Fluoride is naturally present in some water sources, plants and animals. The most common fluoride additives in toothpaste include sodium fluoride and stannous fluoride.

Fluoride works to replace the calcium and minerals lost in the demineralization/decalcification process. Fluoride binds with the tooth to form and even harder surface to reverse the decay process.

This fluoride can be gained from applying toothpastes or mouthwashes. The way in which fluoride works is well documented and tested so that we know how much is beneficial.

However, it is well documented that too much exposure to fluoride can harm the body. If we swallow too much fluoride it can be included in our teeth and bones in higher amounts, causing what is known as fluorosis. Whilst this is normally harmless in small amounts, it can cause disease in large amounts.

How much fluoride children are ingesting is obviously a worry to adults training their children not to swallow the paste. This is especially difficult considering the flavorings used to encourage children to enjoy brushing. This is why children’s toothpaste has a lower amount of fluoride in it.

In addition to the fluoride we put in our mouths, in some parts of the world, we are exposed to fluoride on a daily basis through our water supply. In some areas of the USA the water has naturally high amounts of fluoride in the water supply. India and Nigeria also have high amounts of fluoride in the water.

While it is generally agreed that fluoride is overall beneficial to the teeth, some people worry that they are ingesting potentially harmful amounts.

In the US the FDA does not allow for a high concentratios of fluoride to be allowed in toothpastes as it can damage developing teeth. Some people argue the current concentration is too weak to have any real effect. Another problem is that the fluoride can’t work until all biofilm has been removed, so some dentists suggest applying a mineralizing paste after brushing, such as GC MI Paste (view on Amazon). Such pastes use different minerals to help re-harden the teeth and can eliminate the need for fluoride containing toothpastes.

Fluoride-free toothpaste

If the normal precautions are taken (i.e. using a pea-sized amount of toothpaste twice daily, and don’t swallow the paste after use), then fluoride is safe for the majority of the population.  Fluoride is only unsafe for very young children (0-3 years) and people with a fluoride allergy.

According to the American Dental Association, children should be introduced to fluoride in very small, pea-sized doses between the age of 3 and 6. Adult toothpaste should not be used on children because of the fluoride content.

Using a toothpaste without fluoride will mean that you do not get the protective remineralization effect of regular toothpaste. This may not be a concern if you are of very low risk of dental decay or tooth wear, but you could discuss this with your dentist.

Some toothpastes use an alternative to fluoride to help the teeth remineralize, for example GC Tooth Mousse which uses a type of calcium phosphate.

If you do decide to opt for a toothpaste without fluoride – either as a way to reduce your fluoride intake or because you have an allergy, below is a list of fluoride-free toothpaste brands for you to consider.

Polyethylene (plastic microbeads)

This toothpaste ingredient has caused an uproar in recent times. As a result the inclusion within toothpaste has now been banned.

It was in 2014 that dental hygienist Trish Walraven first spotted that plastic from toothpaste was being embedded in patients’ gums, prompting her to launch her own investigations. She found that these blue specs don’t dissolve in alcohol or acetone, and that Crest/Oral-B avoids stating overtly that they are using polyethylene on their ingredient list on the tube. Ms Walraven also noted that the beads were getting trapped in the sulcus surrounding teeth. You can read more about her findings here.

It turned out that some toothpaste manufacturers (the most notable including Crest/Oral-B) were using microbeads for the sole purpose of adding color to their toothpaste. See the photos below from dentalbuzz.com

Microbeads in toothpaste
A sample of toothpaste with microbeads in it

These decorative beads are in fact a non-biodegradable type of plastic — the kind used to makes bins, containers and carrier bags. Despite many dental professionals warning of potential dangers such as periodontal disease, Crest/Oral-B persisted with its message that the use of a non-biodegradable material in our mouths is ‘completely safe.’

Smear of toothpaste with microbeads
The same toothpaste sample smeared out flat

This was Crest/Oral-B’s statement (view it here on Washington Post) back in September 2014 when the use of microbeads in its toothpaste was first revealed:

“While the ingredient in question is completely safe, approved for use in foods by the FDA, and part of an enjoyable brushing experience for millions of consumers with no issues, we understand there is a growing preference for us to remove this ingredient. So we will.

We currently have products without microbeads for those who would prefer them. We have begun removing microbeads from the rest of our toothpastes, and the majority of our product volume will be microbead-free within six months. We will complete our removal process by March of 2016.”

Ms Walraven’s blog garnered enough attention to make national news. While the American Dental Association did not retract its seal of approval for Crest’s plastic pastes, the public outrage did provoke the company into agreeing to phase out the use of microplastics by the year 2016.

This may seem like old news by now – after all, microbeads are now banned – but there are some important takeaways that apply despite the changes:

  • Do your own research – you can’t necessarily trust what’s in store-bought toothpastes, which one would naturally assume are ‘safe’ for consumption. It took a dental hygienist to notice and test this arguably harmful ingredient!
  • Despite the findings,  Crest continued to insist that its microbead toothpaste was safe to use and the American Dental Association did not retract its seal of approval for Crest’s plastic containing pastes. This gives you a good indication of to what extent you can trust such a seal. Again, always double check ingredients for yourself and decide what you are personally happy to put in your mouth.

Aside from health and safety concerns, these beads are proving harmful for the environment and for the fish population. This GreanPeace article explains in detail how microbeads are harmful for the environment, but in a nutshell they are so small that they cannot be filtered out of our sewage system and end up stuck in the water supply. So even though the likes of Crest can argue that microbeads are ‘safe’ in their toothpaste, the secondary effect is that they pollute the environment.

It’s worth noting that Polyethylene is on the FDA’s prohibited list as it may lead to 1,4-dioxane contamination. 1,4-dioxane is a cancer-causing chemical. It’s also present in SLS foaming agents. Prior to the new laws, parent company of Oral-B and Crest (Proctor & Gamble) were not required by law to remove it from their toothpastes because the levels are so low that current organizations have deemed it safe for humans.

We would urge you to reconsider your use of any toothpaste or beauty product that uses polyethylene / microbeads, both for the good of your own health and for the environment.

Toothpaste without microbeads / polyethylene

Toothpastes on sale in the USA should now come without microbeads / polyethylene.

Triclosan

Triclosan is an antibacterial ingredient. It works by fighting the bacteria that cause dental decay and gum disease.

Triclosan has been tested in clinical trials and how effective it is at removing bacteria has been proven.

The FDA has not refuted nor validated the use of triclosan, but on its site, it states that ‘in 1997, FDA reviewed extensive effectiveness data on triclosan in Colgate Total toothpaste. The evidence showed that triclosan in that product was effective in preventing gingivitis.’

Studies have shown that triclosan-containing toothpastes are particularly effective for patients with additional needs, and who are unable to brush well. In these cases, triclosan containing toothpastes are more effective than fluoride-containing toothpastes.

However, triclosan is another additive that’s safety has been questioned by some. These concerns relate to the fact that triclosan is an antibacterial, and so can upset the balance in your mouth, possible links to cancer, and that it may also contribute to antimicrobial resistance.

Conversely, other prominent dental professionals, such as Ms Trish Walraven (responsible for exposing Crest’s use of polythene, as mentioned above), argues that science has found that Triclosan does more good than harm.

Studies have shown that triclosan-containing toothpastes are particularly effective for patients with additional needs, and who are unable to brush well. In these cases, triclosan containing toothpastes are more effective than fluoride-containing toothpastes.

In 2014 the American Dental Association (ADA) released a statement announcing that the only paste to which they have afforded their seal of approval regarding triclosan is Colgate Total. The ADA rarely affords its seal of approval to any toothpaste manufacturers outside of Crest and Colgate.

Sodium Lauryl Sulfate (SLS)

SLS is a detergent that is used as a foaming agent. It’s used in products like toothpaste and shampoo so that the substance lathers, enabling us to spread it easier. In toothpaste, it’s a type of soap that helps to dissolve dental plaque. SLS’s toxicology has been called into question, but some recent studies have proven it’s not a carcinogen.

What can potentially cause cancer is 1,4-Dioxane contamination. 1,4-Dioxane is a by-product of SLES, sodium lauryl ether sulfate. Trace levels must therefore be measured. In the US the FDA encourages manufacturers to remove 1,4-Dioxane, but federal law does not enforce this.

It is believed that SLS can cause canker sores / mouth ulcers for some people. The BBC reports on one study that wasn’t all that conclusive, but still recommends trying an SLS-free toothpaste if you do suffer from mouth ulcers:

“In one trial, 90 people who regularly suffered from mouth ulcers were asked to try 8 weeks on a toothpaste with SLS, and 8 weeks on an SLS-free toothpaste. The trial was ‘double-blind’, so neither the participants nor the researchers knew who was using which toothpaste. The researchers found that the SLS free toothpaste did not reduce the number of ulcers or the frequency with which people got them.

“However, they did find that while using the SLS-free toothpaste, the volunteers self-reported feeling less pain and that the ulcers healed slightly quicker.”

Colgate deems SLS detergents ‘important’ in allowing foaming to occur. SLS is the reason foaming occurs. And foam is arguably an unnecessary component in brushing. It doesn’t help clean the mouth, all it does is provide a lather for you to spread the product around more easily.

SLS-Free Toothpaste Brands

There are many toothpastes out there without Sodium Lauryl Sulfate (SLS).  Be aware that these toothpaste often also exclude fluoride (but not always).  Some of the options include:

  • Redmond Earthpaste: Only natural ingredients such as essential oils and salt
  • Sarakan Toothpaste: No parabens, SLS, fluoride, added colors or preservatives
  • Oranurse: No SLS, flavor-free, contains fluoride
  • Australian Tea Tree Toothpaste: fluoride-free and SLS- free, contains aloe vera

Hydrated Silcia

This one is Generally Recognised As Safe (GRAS) by the FDA. It occurs in nature, but can also be manufactured. It is not silicone, and not it’s toxic namesake, crystalline silica. It’s a derivative of silicon dioxide.

What’s worrying about hydrated silica is that it can be contaminated by crystalline silica, so some manufacturers subject their hydrated silica to an x-ray process first before using it in pastes. For some people, using a material that must be x-rayed first is a little disconcerting.

Parabens

Parabens are an ester used as a preservative, therefore helping the toothpaste to last for a long time and in good condition.

Parabens stop the toothpaste from becoming contaminated and works by killing mold and fungus. Paraben is used in so many products that it is now difficult to establish how it is affecting us. One study has linked overexposure with breast cancer, and with so many products marketed at women infused with parabens, it’s no wonder both men and women alike are seeking out ‘paraben-free’ products.

Parabens have even been shown to reduce the sperm count in mice, leading the study to conclude: “These data demonstrated that butyl paraben can exert an adverse effect on the male reproductive system at doses that are well below those of the accepted daily intake (ADI) in Japan.”

Paraben-free toothpaste brands

If a paste doesn’t explicitly state that it’s free from parabens, look for products that claim they are free from artificial preservatives.  Some that are paraben-free include:

  • Himalaya Herbals
  • Sarakan Toothpaste
  • Australia Tea Tree

Colgate also phased out its use of Parabens as of July 2016

Sorbitol

Sorbitol is a naturally-occurring chemical that is used as an artificial sweetener.

Sorbitol is a sugar alcohol that is used as a substitute for sugar, and is often found in sugar-free cakes and candy. In toothpaste, sorbitol helps make the flavor more appealing.

As a sweetener, sorbitol does not feed the bacteria in the mouth, and so does not increase the risk of dental decay and gum disease.

In some people, and at higher doses, sorbitol can cause flatulence, bloating and can aggravate irritable bowel syndrome.

Sorbitol is an ingredient that is listed as Generally Recognised As Safe (GRAS) by the FDA.

Sorbitol-free toothpaste brands

If you’re looking to avoid sorbitol and other chemicals in your toothpaste, look for a paste that uses minimal, natural ingredients. Check for pastes that are ‘unsweetened’, ‘unflavored,’ or without preservatives, such as:

  • Kingfisher Baking Soda Toothpaste
  • Sarakan Toothpaste

Xylitol

Xylitol is a sugar alcohol that is used as a sweetener.  It occurs naturally in some plants, fruits and vegetables. Like sorbitol, it helps to make the flavor of toothpaste more appealing.

As a sweetener, xylitol does not feed the bacteria in the mouth, and so does not increase the risk of dental decay and gum disease.

Xylitol also helps protect the teeth and gums as it helps fight bacteria in saliva that causes tooth decay. It is reported that using up to 20 grams of xylitol per day can significantly reduce the rate of cavity formation in both adults and children. Some studies have proven that xylitol is effective in preventing caries on the root surface of the tooth.

Because of it’s effectiveness, xylitol is also added to sugar free chewing gums, such a Wrigley’s Extra, to help protect the teeth.

Xylitol is more expensive that sorbitol, so its presence in toothpaste is owing to its antibacterial properties. Xylitol is great for people suffering from dry-mouth.

Xylitol can be sourced naturally. Check your toothpaste for non genetically-modified xylitol, such as in Redmond Earthpaste (sourced from corn and birch for use as a ‘natural sweetener’).

Like with many toothpaste ingredients, this substance is carefully regulated. It is not advised that we consume more than 50 grams per day. It’s not suitable for women who are pregnant or breastfeeding as not enough is known about its side-effects. Potential side effects following over-exposure include bloating and diarrhea. Xylitol is toxic for dogs so be careful which paste you are brushing your pet’s teeth with.

Xylitol-free toothpaste brands

Xylitol is everywhere because evidence shows it is good to help prevent tooth decay. There are currently very few pastes on the market that don’t contain xylitol.

Many tests have shown it works wonders for teeth, but it could be toxic in large doses if swallowed.

Charcoal

We have included activated charcoal in this list because of its recent rise in popularity, which we have written about in detail in our charcoal toothpaste guide.

It’s not an ingredient per se, but rather something that toothpaste can be made of.

It comes in the form of either powder or paste and is used for at-home teeth whitening.

At this moment in time there is little scientific proof to show whether or not using activated charcoal for whitening is safe, or not.

However, a recent article on DentistryiQ does highlight one particular charcoal toothpaste, Black is White (view on Amazon), as being safe:

‘What we do know, as of this writing, is there is only one toothpaste containing activated charcoal that appears to be safe. Black is White toothpaste (Curaprox Inc.) uses activated carbon for whitening and stain removal.’

It also talks about how Black is White is different to other charcoal products:

‘Black is White is also differentiated from other activated charcoal products by what it does not contain. It does not contain sodium laurel sulfate (SLS), triclosan, bleaching or chemical agents, or plastic particles.’

We look in more detail at charcoal toothpaste and what has been said about it in this article. If you do decide to use charcoal toothpaste, we recommend proceeding with caution due to the current lack of evidence of its long term effects.

What’s the safest toothpaste?

Taking into account what we’ve said above about toothpaste ingredients, you may be wondering what the safest toothpaste is, especially if you need one to give to your children.

The problem is that some toothpastes contain a number of chemicals that are allowed on the market as science hasn’t yet proven them unsafe.

At present, there are no reports or studies that scientifically prove more regular toothpastes to be unsafe. Most dental professionals will recommend branded fluoride-containing toothpastes as they believe the benefits of the added ingredients will outweigh the potential harm from other ingredients.

And while some ingredients are included in the toothpaste because they help promote dental health, it’s unknown what long term side-effects could be.

As consumers, we look to organizations such as the American Dental Association to approve or reject products for us, but with chemicals like triclosan, tests are still being conducted.

The ADA is supposed to regulate the dental market, yet it did not take steps to condemn, nor remove its seal of approval for Crest when it emerged that the company’s toothpaste was using microbeads, which were found embedded in gums.

Had the problem of microbeads in toothpaste not been discovered by a dental professional, one has to wonder how long the products would have been regarded as ‘safe’ or before scientific testing proved they were problematic.

All in all our recommended toothpaste if you want to avoid any artificial chemicals is Redmond Earthpaste (view on Amazon). However, as we stated at the beginning of this article, you should also do your own research and decide which chemicals you feel are necessary, and which you feel should be avoided.

To provide further examples, if you have a problem with tartar, you might look to a tartar-control toothpaste. The problem is that these have a high abrasive content, which could cause damage to enamel over a long period of time.

Similarly, some brands have chosen to keep triclosan in their formula as it obliterates bacteria, allowing them to claim that their toothpaste is particularly effective — but this also means destroying good bacteria needed in your mouth. There is also speculation that it helps build antimicrobial resistance in bacteria.

So while these ingredients are not regarded as dangerous nor toxic, your personal choice may be to avoid them based on your own situation.

Our personal choice is to stay away from toothpastes containing SLS, triclosan, polyethylene (microbeads) or pastes that have a high abrasive content.

When it comes down to it, toothpaste isn’t the single most important factor to protect your teeth and gums.  All in all we just need it to make brushing easier and more effective.

If you are in any doubt about the ingredients used in your toothpaste, try making your own paste or choosing from organic, natural products that stock to what we know if safe.
