What causes sensitivity to teeth?
The outer layer of the teeth is called enamel. It has a role of a shield that covers and protects the main tooth substance,tooth dentine. When the enamel wears down that exposes the underlying dentine and results in development of sensitivity.
Possible causes for for teeth sensitivity are:
1/ Over enthusiastic tooth brushing or employing incorrect brushing technique thatcould lead to loss of enamel. This usually occurs at the area where gums join the tooth
2/ Gum disease and gum recession could be another reason. Build-up of tartar makes the gum tissue drift away from the tooth which results in exposure of the root surface.
3/ Dental erosion. This is when the enamel is lost because of frequent consumption of acidic foods and drinks
4/ Grinding teeth could cause the enamel to wear away over the course of the time
5/Tooth decay or tooth fracture could expose the dentine
6/ Teeth whitening may lead to increased sensitivity but this is transient and normally easy to manage
