The primary cause of sensitive teeth is exposed nerve roots. The enamel which is the protective outer covering of the tooth can wear away for many different reasons, exposing the nerve roots and inner dentine. If you are wondering what causes sensitive teeth, here are some external factors that are responsible for the short sharp sensation you may experience:
• Aggressive brushing technique: Brushing too hard can damage the enamel of the tooth. Hard-bristled toothbrushes can cause further wear of the outer layer of the tooth. This leads to sensitive teeth.
• Cavities and gum diseases: Gum diseases such as gingivitis are responsible for receding gums leaving the nerve roots more exposed. Plaque build-up is also responsible for tooth decay and infections that eat up the enamel. Treating these underlying issues is the only way to treat tooth sensitivity.
• Teeth grinding: Teeth grinding or bruxism regularly can damage your teeth and cause sensitivity. Some causes of teeth grinding have been linked to sleeping disorders or stress.
• Teeth whitening: Teeth whitening procedures are being commonly used to get rid of discolored teeth. However, the problem with such a procedure is that they use abrasive chemicals during these treatments which can make your teeth more sensitive.
• Acidic foods: Are there other reasons what causes sensitive teeth? Yes, food such as oranges, lemons, and wine can wear your teeth away over time. As you enamel wear away you might feel twinging or discomfort when you consume hot and cold food. This type of acidic erosion can cause some serious dental problems in the long run.
Therefore, while there are several answers to what causes sensitive teeth, we must have a good oral hygiene routine to keep these problems to a minimum. Your dentist is the best person to diagnose tooth sensitivity and recommend the best solutions.
