Only your dentist can tell for sure whether you have tooth decay.
That is because cavities develop below the tooth’s surface, where you can not see them. Using higher magnification and powerful lighting, it is easier to detect decay at an early stage to prevent excessive tooth damage. Regardless of where cavities occur, the best way to spot them and treat them before they become serious is by visiting your dentist regularly for check-ups. As when cavities are small, they are much easier and less expensive to treat.
