I'm really self-conscious about my cavities, and brush and floss twice a day. what can i do to not feel bad about this?

Restore them: There's an easy solution... Have your cavities restored. By your local dentist. Brushing and flossing will help maintain your teeth, but not fix the carious lesions.

Make a change: The first step is recognition, which you just expressed. The second step is making a commitment to restore your mouth to health and beauty. This can be accomplished, but it will take the time, money and effort to see a dentist, find out what needs to be done, and then follow the recommended treatment plan. We have many methods to accomplish this and can get fantastic cosmetic results.
