CHOOSING THE RIGHT TOOTHBRUSH
What type of toothbrush should you choose? Having so many options available can make picking the right brush for you overwhelming. In general, dental professionals recommend that everyone use a soft bristled brush. The shape and size of the brush head and handle, as well as the style of bristles (flat, rippled, etc.), that you choose should be the one that is most comfortable for your mouth. The best toothbrush for you is the one that fits the best in your mouth and reaches all of your teeth. Many people find that a powered toothbrush is a good alternative. This is a particularly true for those who have difficulty brushing or have limited dexterity.
You should also be sure to replace your brush (or brush head if you are using a powered brush) when it begins to show wear or every three months, whichever comes first. Also be sure to change your toothbrush any time you have been sick to prevent reinfection.
