BEST ROOT CANAL SPECIALIST IN CHENNAI ! Difficulty in eating. A throbbing jaw. Temperature sensitivity. These are a few of the unpleasant symptoms that often accompany tooth pain. 1.Tooth decay. This is a leading cause of tooth pain. When your enamel wears thin, the teeth can become more sensitive to hot and cold temperatures, resulting in sudden pain. Tooth decay is also responsible for cavities. 2. Infection. A tooth infection can happen when bacteria infects your tooth, often times due to a crack, chip or a cavity. If you don’t properly care for your teeth every day, you’re more likely to develop a tooth infection. Whether you’re dealing with an ongoing dull ache or a sudden sharp pain, chances are a visit to our practice at APPLE DENTAL is necessary. In fact, we recommend scheduling a visit with the dentist if you’ve had any sort of tooth or mouth pain for more than 24 hours.
