Tooth Sensitivity

Tooth Sensitivity

Tooth sensitivity (dentine hypersensitivity) is a common concern for many of our patients, in fact close to half of the Australian population are affected by sensitive teeth! If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful then you may need our help & advice.

It is important to let us know if you have any sensitive teeth, so we can examine your mouth, see if the problem is tooth sensitivity and help you choose the best treatment. When teeth are sensitive it can be painful to brush them and if you brush poorly because of pain then there is more risk of tooth decay and gum disease. Pain after hot, cold, sweet or acidic foods and drinks can also be a sign of decay or even a sign of a broken tooth or infection. If this is the case we will discuss your treatment options.

 So you may ask how do our teeth become sensitive?

When the root of a tooth becomes exposed it does not have a layer of enamel like the crowns of your teeth. Instead the roots have a very soft covering called cementum, which once lost leaves the dentine of the root exposed. Overzealous brushing or using an abrasive toothpaste can also cause loss of the tooth’s enamel surface and expose dentine. A very acidic diet can cause tooth erosion and dissolve the tooth surface, exposing the dentine. Tooth sensitivity is usually caused by dentine on root areas exposed due to receded gums or periodontal disease. 

You can reduce your chances of getting tooth sensitivity by keeping your mouth as healthy as possible with good oral hygiene to help prevent receding gums and periodontal disease.

  • Brushing & flossing properly as recommended
  • Using a low abrasion toothpaste
  • A diet low in acid

Ignoring your sensitive teeth can lead to other oral health problems, especially if the pain causes you to brush poorly making you vulnerable to tooth decay and gum disease.

We have a variety of regimens to manage tooth hypersensitivity, including both in-office treatments and patient-applied products for home use. A fluoride varnish or an over-the-counter desensitising toothpaste containing fluoride and either potassium nitrate or strontium chloride creates a protective varnish. These ingredients help block the transmission of sensation from the tooth to the nerve.

Toothpaste for sensitive teeth usually contains a desensitizing agent that protects the exposed dentine by blocking the tubes in the teeth that are connected to nerves. We recommed that these products are used on a regular basis & exclusively for at least a month before any therapeutic benefits may be noticed. It also might help to massage the paste onto your gums with your finger after brushing.

  1. I used different sensitive teeth toothpaste for get relief my sensitive teeth but could not get relief, than I used Colgate Sensitive toothpaste. Colgate Sensitive toothpaste provides the benefits of normal toothpaste with the added benefit of sensitivity relief. It soothes the nerve ends and builds a protective shield providing both relief from sudden shocks of pain and long term sensitivity protection with regular use.
