Do you feel a sudden pain when you eat foods that are a little too hot, cold or sweet? It could be that you have sensitive teeth. There are many possible causes of dentin hypersensitivity, such as tooth decay, worn fillings or periodontitis (gum disease), but generally, sensitive teeth are the result of worn tooth enamel or exposed dental roots. In fact, when the enamel (the tooth’s protective layer) deteriorates or the gums around the tooth recede, it’s the dentin that becomes exposed. Dentin is a layer of tissue beneath the enamel and on the root containing tiny canals or “tubuli”. These tubuli allow heat, cold and sweetness to reach the nerves inside the tooth. The result is sensations of pain, or hypersensitivity.

Can dentin hypersensitivity be treated?

There are various treatment options that your dentist can suggest, depending on the cause and severity of the sensitivity:

Desensitizing toothpaste : Over-the-counter desensitizing toothpaste contains compounds that help block the transmission of sensation from the tooth surface to the nerve. After a few uses, you may notice a difference in sensitivity.

Fluoride gel: Fluoride gels are an in-office technique that strengthens tooth enamel and reduces sensitivity transmission. At your cleaning appointment, it can be provided to help with sensitivity.

Crown, inlay or filling: These techniques can be used to correct a defect (crack or fracture) or decay that is causing sensitivity.

Gum grafting: In the event of gum loss at the root, this procedure can be used to protect the root and reduce sensitivity.

Root canal treatment: If sensitivity persists and cannot be treated by any other means, your dentist may recommend a root canal treatment to eliminate the problem.

Tooth sensitivity should not be ignored. A dental examination will allow your dentist to determine the cause of your pain and recommend the right treatment for your teeth.
