Adults should go for a small-to-medium-sized brush head. This should have soft-to-medium, multi-tufted, round-ended nylon bristles or ‘filaments’. The head would be small enough to reach all parts of the mouth - especially the back of the mouth where it can be difficult to reach. Children should use smaller brushes but with the same type of filaments. It is now possible to buy more specialized toothbrushes. For instance, if you suffer from sensitive teeth, you can now use softer bristled brushes. There are also smaller brush heads for those with irregular-shaped teeth. Some may also find it difficult to hold a toothbrush, for example, because of limited movements or disabilities. There are now toothbrushes which have large handles and angled heads to make them easier to use.
