Why are my teeth so sensitive, especially to cold?
Teeth sensitivity can be caused by many factors. A sudden increase in sensitivity to hot and cold temperatures, or discomfort when you bite down can be a sign of nerve involvement due to decay or fracture.
However, one of the common reasons for sensitivity is aggressive brushing habits. People use abrasive toothpaste and tend to apply a lot of pressure with their toothbrush in the mistaken belief that this will get their teeth whiter and cleaner.
Unfortunately, the tooth enamel gets eroded, exposing the dentin beneath. This leads to increased sensitivity and a higher risk of decay. You may also notice that your teeth are darker since the enamel which is lighter and brighter has thinned down or is missing.
Habitual grinding or bruxism usually happens with an increase in stress, but also results in significant wear and enamel loss causing increased sensitivity. Extensive use and misuse of whitening products can also increase the risk of sensitivity.
Teeth can also be sensitive right after restorations or after your cleaning visits due to the exposed dentinal surfaces or transient nerve irritation.
Fluoride varnish is recommended right after your hygiene visits to help minimize sensitivity. We also prescribe desensitizing toothpaste if we see a need, an occlusal guard to protect from grinding-related issues, and composite resin material to seal some of the areas of deep abrasion and sensitivity.
