What Causes Sensitive Teeth?

Do you cringe at the thought of eating something sweet or cold? Do you prefer room temperature drinks? Then you are not alone! Tooth sensitivity is one of the most common dental problems, with millions of Australians avoiding cold and sweet foods.

There are many different causes of tooth sensitivity. Fortunately, once you know the cause, you know how to fix it! In this post, we will outline the most common causes of tooth sensitivity and how you and your Sunshine Coast dentist can help you.

[H2] Suffering From Sensitive Teeth?

When tooth enamel wears away or gum recession occurs, this can expose the inner part of the tooth called dentine. This is where the nerves are, and what causes sharp pain when exposed to cold foods and drinks. Other common causes of tooth sensitivities include:

Receding Gums

Under the layer of enamel, the dentin has tiny tubes that lead to the tooth’s pulp. When gums recede, these tubes become exposed, and the nerves are more vulnerable to stimuli such as hot and cold food and drinks. Gum disease, including gingivitis and periodontitis, can also cause sensitivity in the teeth.

Brushing Too Hard

When it comes to brushing, some people think more force is better. However, when you brush too hard, you can actually wear away the enamel on your teeth and erode the gums, causing sensitivity.

Cracked or Decaying Teeth

When bacteria builds up inside or around a tooth it can cause the enamel to erode away and the tooth to crack. This exposes the dentin and can cause sharp pain when eating or drinking.

Grinding Teeth

Teeth grinding, or bruxism, is a common cause of tooth sensitivity. When you grind your teeth, you can wear away the enamel and expose the dentin. You may also develop cracks in your teeth, which can lead to sensitivity.

Acidic Foods and Drinks

Over time, certain foods, drinks and even some acidic mouthwashes can erode tooth enamel.

Dental Procedures

It is normal for some people to experience sensitivity after various dental procedures such as a root canal, extraction, or even a filling. However, this is often temporary and will go away on its own.

How to Treat Sensitive Teeth

If you are experiencing sensitivity, the first thing you should do is visit your dentist. They will be able to determine the cause of your sensitivity and recommend the best course of treatment.

There are also some things you can do at home to help ease tooth sensitivity such as:

  • Use a soft-bristled toothbrush
  • Avoid acidic foods
  • Try a sensitive toothpaste
  • Use a fluoride rinse
  • Practice good oral hygiene, including proper brushing/flossing and regular dental visits

If your sensitivity persists, please visit your dentist. There are different treatments that can help depending on the severity and cause of your sensitivity. These include fluoride gels, tooth bonding, fillings and sealants. In the event of severely infected and eroding gums, extraction may be the best treatment.
