Most dental professionals agree that a soft-bristled brush is best for removing plaque and debris from your teeth. Small-headed brushes are also preferable since they can better reach all areas of the mouth, including hard-to-reach back teeth.
When it comes to the type of handle (such as non-slip grip or flexible neck), the shape of the head (tapered or rectangular) and style of bristles (such as rippled, flat or trimmed to a dome shape), pick whatever is most comfortable for you. The best toothbrush is one that fits your mouth and allows you to reach all teeth easily.
For many, a powered toothbrush is a good alternative. It can do a better job of cleaning teeth, particularly for those who have difficulty brushing or who have limited manual dexterity.
