What Causes Sensitivity to Hot and Cold?
It can be hard to enjoy foods and treats like soup and ice cream when they cause a sharp pain in the teeth. Teeth are hard and meant for chewing foods, so it doesn’t seem right that very hot or cold substances would hurt them. Teeth are covered with enamel, which protects the deeper layers of the teeth from this feeling. Unfortunately, sometimes the teeth aren’t taken care of well enough, and they become sensitive.
This occurs in two different ways. When decay affects the gums, the gum line can recede, revealing part of the tooth that is not protected by enamel. Foods at extreme temperatures can thus reach a more sensitive part of the tooth. Decay can also eliminate enamel, leaving the underlying dentin exposed. Dentin features tiny holes that lead to the inner layer of the teeth. This means that hot and cold foods and drinks are reaching the pulp of the tooth, where the nerves live, which creates an unpleasant experience.
There are several ways those with sensitive teeth can correct the problem. Maintaining good oral hygiene is one of them. This can be done by cleaning the teeth every day and visiting your dentists regularly for a dental exam. Patients can also avoid highly acidic foods, use a toothpaste specifically made for sensitive teeth, and wash their mouth out every day with a fluoride rinse. Those who grind their teeth habitually should see a professional about the issue, as the act can significantly wear down enamel.
