Use a soft-bristle toothbrush. Soft bristles are better than medium or hard bristles at getting into those nooks and crannies around your appliances. They also don't irritate your gums.
Some companies make toothbrushes especially for people with braces. Known as bi-level brushes, they have longer bristles on the edges and shorter ones in the middle. This type of brush allows you to clean the area above and below the brackets as well.
The most important thing is to look for a brush that's soft. After that, the size of the brush, the shape of the handle and other variations are up to you.
What about an electric toothbrush? It's not necessary, but if you have one, it's safe to use it on your braces. Just be careful not to hit the plastic back of the brush against the brackets on your braces because it can damage them. Also, it should be used on a moderate setting so as not to break or loosen braces.
Brush at least three times a day. It is best to brush after meals to make sure there's no food trapped in or around braces. If you are not able to brush after lunch, at least rinse your mouth with water very thoroughly.
Brush for at least two to three minutes each time. It's best to use a watch or timer to make sure you are brushing long enough.
Brushing should be done slowly and carefully, It's important to brush the braces and all the surfaces of the teeth, that is, the inside and outside surface and the chewing surfaces, too. Pay special attention to the areas between your brackets and your gums.
