If you have seen or own an Oral-B electric toothbrush, you may well be wondering what the purpose is of the colored ring at the bottom of the brush head.
The purpose is really quite simple.
The colored ring is put in place to tell the difference between each brush head.
For example, if you had a family with a mum, dad, son, and daughter, each may have their own brush head that can be used on their Oral-B electric toothbrush.
The color of the ring is what can be used to identify whose brush head is whose. Mum may have a red colored ring, whilst Dad has a blue ring, the son green, and the daughter pink.
The colored ring serves no other purpose than that.
Why they are needed?
It may not apply to you but taking the above scenario, if every member of that family uses the same style of brush head how would you ever tell the difference?
You should always use your own toothbrush/brush head and not share as doing so can pass potentially dangerous bacteria between mouths.
When you have 4 brush heads all lined up the only way to tell the difference is by the colored ring.
I have lost the colored ring, does it matter?
Yes and no. The colored ring serves no other purpose than to tell brush heads apart, so if you are not in a family scenario like above where you need the ring to tell it apart from another brush head then do not worry.
Without the ring, the brush will perform no differently.
Can I swap colored rings from other brush heads?
Whilst the brush head itself should be changed every three months, the colored ring has no pre-determined life.
Most will dispose of the colored ring at the time they dispose of the used brush head, but using your fingernail you can pull the ring off and attach it to a new or different compatible Oral-B brush head.
So for example, you liked the yellow colored ring on your old brush head, but the new one has come with a blue ring. Pull the yellow one off the old head and attach it to the new one.
How can I buy more colored rings?
Oral-B does not sell the colored rings on their own. There are some third party sellers on Amazon and eBay who may sell the rings, but due to their low value and low demand, they are not readily available. You will not find them at your local supermarket.
Do remember with any new brush head purchase will come with a colored ring.
Can I choose the color ring on the brush head?
Yes and no. When you buy a new brush head you cannot request or determine the exact color of the ring(s) included in the pack.
If buying in person you may well be able to see these through the packaging but no if you are buying online.
You may choose to take a colored ring from an old brush head or your preferred color from the pack of heads and swap it each time you change the head.
Why do other electric toothbrushes not have this?
Generally speaking, this is seen only on Oral-B brushes. Other brands may have their own way of differentiating brush head or work on the basis that in reality, whilst it makes perfect sense to share a toothbrush handle, even in a family environment users often have one electric toothbrush each, thus the need for the colored ring is redundant.
LED Smart Ring – A different type of colored ring
A different type of colored ring found on some Oral-B toothbrushes is the LED Smart Ring.
Unlike the rings that fit at the bottom of the brush head, this smart ring is quite different.
The ring is built into the brush at the time of manufacture and comes on some of the more premium Bluetooth enabled Oral-B electric toothbrush models.
When connected to a smartphone, via the Oral-B application, the smart ring can be changed to 1 of 12 different color options.
The brush then illuminates the ring with the chosen color whilst the toothbrush is turned on.
The smart ring is designed for adding a personal touch and is not aimed at differentiating one toothbrush or brush head from another.
Having said this, the smart ring does double up as the visible pressure sensor, lighting up red when too much pressure is applied. It will on some models also flash at 30 second and 2 minute intervals as part of the built-in timer mechanism.
