White fillings are the go-to solution for anybody suffering from a cavity. Cavities are generally caused by a buildup of tartar, which is the result of hardened plaque. It is extremely important to maintain good oral hygiene to avoid excess plaque buildup, as tartar is much more difficult to remove and can only be cleaned by a professional. By consistently keeping good oral health through brushing twice daily, flossing once a day and attending your regular dental checkups, white fillings will likely not be necessary. In the unfortunate event that you or your dentist discover a cavity, they will be the most suitable treatment option.
