How often should you get a new toothbrush


This is a very common question that's difficult to answer without seeing your actual brush

We are often asked this one, & without seeing yours, it's a very challenging to describe to patients how & when is the right time to change their toothbrush.

For some people a brush could need changing every 1-3 months, for others who are very gentle on theirs it could last up to 6 months.

As a rule the softer bristled ones wear faster BUT don't use a stiff bristled brush just because they will last longer, you are more likely to adversely wear your teeth!

They say a picture paints a thousand words, so here are some pictures that should help you out

Normal Hand toothbrushes

Electric Toothbrush Heads

Exactly the same principles apply to these. Look for curled bristles and stray ones, also most of the electric toothbrush heads have a colouring that fades in some of the bristles which indicates when the head need changing.

Take a look at the information on a new one in the packet as this varies slightly from one manufacturer to another. 

The picture below is an Oral-B one.
