A filling repairs and restores the surface of the tooth that has been damaged by decay, fracture, or wear. A dental filling strengthens the tooth. If tooth decay is not repaired at its earliest stages, it will worsen and additional or alternative dental treatments may be necessary.
Tooth sensitivity is the most common early warning sign of enamel loss due to decay or wear. While there could be a number of reasons for this sensation, only your dentist can diagnose its underlying cause. If a damaged tooth surface is not treated early, your discomfort will increase.
