It’s the season of ice cream, but for people with sensitive teeth, there’s less cause to be happy about that. We at Dr. Martin Urban’s Waltham office hope that all our patients are free of dental pain. If they do suffer from sensitivity, it could be a red flag for loss of enamel.
Each natural tooth contains a nerve and blood supply. Surrounding the dental pulp is a layer of hard material called dentin, which is a yellow-grey color. Enamel is the outermost layer of a dental crown and when it is thin, dentin may be visible through it. The roots of the teeth are surrounded by a substance called cementum, which is not as hard as enamel and serves to seal the tooth to its gum pocket.
Dentin is made up of tiny tubes and easily transfers heat to or from the dental pulp. When enamel has been reduced or gum tissue has receded, there is little to shield the sensitive nerve. Although a tooth may crack under pressure, it is more common for acid caused by bacterial infection or regurgitated by the stomach to dissolve enamel and gum tissue, making a tooth more sensitive. Implanted-supported crowns don’t have this problem, but we still work to preserve patients’ natural teeth by filling in cavities after drilling away infections. Patients may also try remineralizing their enamel by using extra-fluoridated toothpaste.
