Big vs Small: Which is better toothbrush for you?

by Zach Miller 08 Mar 2024

When it comes to selecting the perfect toothbrush, size matters — and I’ll get straight to the point, smaller proves to be the better choice.


Why opt for a smaller toothbrush? Let's draw a parallel to a common household task: cleaning a water bottle. To effectively scrub those hard-to-reach areas at the bottom, (or maybe a straw coming with it) a smaller brush is essential.

The principle is quite similar when it comes to brushing your teeth, especially the molars. While the size of a toothbrush might not make a significant difference for easily accessible front teeth, the challenge arises when cleaning the backside, such as molars and areas near the gum line.

For specialized dental care — whether it’s for molars, braces, or implants — tuft toothbrushes are available. Yet, the catch with using smaller toothbrushes is the time it takes to thoroughly clean all your teeth. With our busy lives, spending an inordinate amount of time on oral hygiene can feel like a burden, potentially leading to skipped sessions.


So, what’s the ideal toothbrush size?


It’s widely agreed upon that smaller toothbrush heads are preferable. However, the increased time needed for a comprehensive clean with a smaller brush can make brushing feel tedious. To strike a balance, we suggest a specific size guideline for toothbrushes.


We recommend using a toothbrush with a head length that does not exceed the width of two teeth, and a width not larger than a single tooth.

This recommendation aims to combine efficiency with thoroughness, ensuring your brushing routine is both manageable and effective.



As established, when in doubt, smaller is indeed better when selecting a toothbrush. This ensures you can reach and clean all areas of your mouth effectively, particularly those tricky spots around molars and near the gum line.


For more personalized advice specific to your oral health needs, consulting with a dentist is always the best action. They can provide personalized recommendations based on the unique characteristics of your mouth.


Choosing the right toothbrush size can significantly impact your oral health routine, making it easier to maintain clean, healthy teeth and gums. Remember, the best toothbrush is one that you will use consistently and effectively, fitting into your lifestyle while ensuring the utmost care for your oral hygiene.
