Signs You Have Sensitive Teeth and How To Treat It


Is the taste of ice cream or a sip of hot coffee sometimes a painful experience for you?


Does brushing or flossing make you wince occasionally? If you answered yes to any of these questions, then you may have sensitive teeth. Having sensitive teeth is often a sign of a deeper underlining issue such as Tooth decay, Worn fillings, Gum disease, Exposed tooth root and could be caused by any of these instances. 

In healthy teeth, a layer of enamel protects the crowns of your teeth i.e the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin. 

Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

The good news is that sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity, and a dentist may suggest one of a variety of treatments:

Desensitizing toothpaste: This contains compounds that help block transmission of sensation from the tooth surface to the nerve, and usually requires several applications before the sensitivity is reduced.


Fluoride gel: An in-office technique which strengthens tooth enamel and reduces the transmission of sensations.A crown, inlay or bonding: These may be used to correct a flaw or decay that results in sensitivity.


Surgical gum graft: If gum tissue has been lost from the root, this will protect the root and reduce sensitivity.


Root canal: If sensitivity is severe and persistent and cannot be treated by other means, your dentist may recommend this treatment to eliminate the problem.

Proper oral hygiene is the key to preventing sensitive-tooth pain.
