To avoid tooth decay, you should brush your teeth after every meal or snack and floss daily if you wear braces.
Use an interdental brush (a tiny brush that goes between the teeth) to get into all the crevices.
Research suggests that people who straighten their teeth with clear aligners experience fewer cavities, less tooth decay, and have fewer gum problems than people who wear braces. To prevent bacteria and calcium buildup, wash your aligner with Invisalign’s cleaning solution after each meal.
