What causes sensitive teeth ?
As your local dentist we’re here to help you with your dental concerns. Teeth may be sensitive for a number of different reasons. Teeth are often sensitive when dentine is exposed.
Dentine is the layer of tooth structure under the outer enamel layer. It has channels(tubules) that go to the inner nerve part of the tooth.
Dentine is often exposed near the gum line, when the gums pull away from the teeth or when gum tissue is lost. Dentine can also become exposed if the outer enamel layer on teeth wears away.
Below are some factors that can contribute to sensitive teeth :
- Tooth decay : This is a common cause of pain on hot, cold or sweet. Treatment may require a filling to be placed in the tooth.
- Brushing too hard or using a toothbrush with hard bristles will lead to gum recession and/or tooth wear.
- Sugary and acidic foods and drinks : this can lead to erosion tooth wear by wearing away the enamel.
- Teeth grinding : this can lead to the tooth surface wearing away.
- Gum disease : this can lead to gum recession. ( the gums shrink back )
- A cracked tooth or filling : A crack can run from the outer surface of the tooth towards the root and the inner part of the tooth.
- Age : Gums can naturally recede over time.
- Teeth whitening : Some patients have sensitivity for a short time after teeth whitening.
Tips to help prevent sensitivity :
