Tooth sensitivity can be caused by a variety of factors and can affect different parts of your teeth.
Layers of the Tooth
Enamel: The hard layer that covers the top part of the tooth is the enamel. The enamel is hard and dense and protects the underlying layers from the external environment.
Dentin: This is the layer underneath the enamel and the dentin makes up the majority of the tooth structure.
Pulp: This is the inside of the tooth that contains the nerve and blood supply.
Factors The May Lead to Tooth Sensitivity
There are many factors that could lead to the development of tooth sensitivity, including:
Worn tooth enamel from using a hard toothbrush or using too much force while brushing the tooth.
Gum recession often leaves the root surfaces exposed. This may be caused by gum disease or by brushing too hard.
Grinding or clenching your teeth can wear away your tooth enamel. Grinding usually occurs at night while you are asleep.
Tooth erosion due to highly acidic foods and drinks, or stomach acid due from reflux or vomiting. Pregnancy, eating disorders and conditions relating to reflux disease can increase your risk of erosion so you should take extra care with your teeth in these situations.
Chipped, broken or decayed teeth can cause the nerve in the tooth to become irritated and sensitive.
