There may be various causes of dentin hypersensitivity. The main cause is, however, exposure of root surfaces, loss of cementum layer and tooth wear. The soft layer or dentin makes up the inner part and roots and have thousands of tiny tubes that lead to the tooth’s nervous system. These channels, when come in contact with the external stimuli, you feel a sharp pain as the trigger reaches the nerve of your tooth. Other reasons may include the following:

Use a fluoridated toothpaste instead of a tartar control one. Spread a thin layer of it on the exposed tooth roots when you go to bed. Try a few products to see which one suits your needs best.

If your sensitivity stays more than a few weeks, consult your dentist. Your dentist will clean the teeth using proper chemicals and apply a fluoride varnish that reduces sensitivity temporarily. Then the in-office treatment is applied, which closes the openings in dentin and reduces sensitivity. A laser treatment is also available nowadays, which alters the tubules and reduces sensitivity.

Ask your dentist to prescribe acid-free fluoride toothpastes and mouth rinses to give you long term, as well as instant relief. Make sure to consult your dentist once in a while so that the problem does not turn back.
