There are a number of reasons that teeth may become ‘sensitive.’ Tooth sensitivity typically occurs when the enamel has been weakened over time by excessive wear, or acidic foods and drinks. The worn enamel allows hot, cold, acidic or sugary substances to penetrate in small amounts through to the nerve, causing discomfort. If there are no other underlying causes, such as tooth decay or fracture, a toothpaste formulated for sensitive teeth may be recommended to sooth tooth sensitivity.
Teeth may also become sensitive with signs of gum disease. The plaque and bacteria that form at the gum line will eventually cause the gum tissue to recede, exposing tooth root surfaces. These ‘pockets’ that form between the tooth and gum will make teeth more susceptible to sensitivity from certain foods, beverages, or hot and cold temperatures.
If particular teeth are highly sensitive, this may be a sign of tooth decay or fracture. Even a small cavity can cause a lot of discomfort. A minor crack or flaw in a tooth will leave the nerve unprotected, which can be quite painful. A tooth that has been weakened by decay or fracture will show signs of sensitivity, and worse, will continue to erode.
It is important to address signs of sensitive teeth as soon as possible to rule out, or treat, underlying dental conditions that may be causing the discomfort. Schedule a complete examination today to discuss any concerns you may have with Athens dentist Dr. Lane Barker.
