Tooth cavities are a result of bacterial activity within the mouth which results in tooth damage. Cavities can form on any surface of the tooth (front or back, chewing surface or near the gums) and appear like black holes. Food can get stuck in such teeth or the tooth can be sensitive to warm or cold foods and air. Here at SmileVel dental clinic Nizampet, we carefully remove the damaged part of tooth cavities and place white tooth fillings, restoring them back to normal shape and function.
