4 Reasons Why You Have Sensitive Teeth

Do you avoid drinking hot beverages or eating cold food because of sensitivity? If you answered yes, then it may be the time to let the friendly team at our Dental Clinic Pimpama get to the bottom of this painful condition.

Research published in the Australia Dental Journal suggests that 1 in 5 dental visits in Australia are due to dentin Hypersensitivity, otherwise known as ‘sensitive teeth’. The pain associated with sensitive teeth can range in severity from a minor annoyance to chronic discomfort.

Are you curious about what can cause sensitive teeth? Here is a list of the most common reasons for the problem and how we can help to fix the issue.

1. Excessive brushing with a Harsh toothbrush

It goes without saying that a good oral health routine with regular brushing is an extremely important part of our overall health and wellbeing. However, using the wrong toothbrush and an incorrect brushing method is a common cause of tooth sensitivity. Using a brush with hard bristles can damage the protective layer of enamel that surrounds our teeth. If you combine this hard brush with excessive pressure the enamel can chip away, leaving the dentin underneath exposed which can create tooth sensitivity.

Following some simple steps can help to prevent this problem;

  • Use a soft bristle toothbrush
  • Hold your toothbrush on a 45 degree angle against the gum line when brushing
  • Replace your toothbrush every 3 months or sooner if it begins to show signs of wear such as splayed bristles.

2. Receding Gum Line

Many people experience receding gums as they age. This can be caused by a number of reasons such as gum disease and teeth grinding. The layer of gum that protects the root of the tooth slowly pulls away, exposing the root which typically is not covered by much enamel. Once this happens, the tooth becomes more sensitive and susceptible to damage.

If you suspect that your gums are receding it is important to visit your dentist to access the situation and prevent any further damage.

3. Consuming too much Acidic Food

Foods such as tomatoes, orange juice, citrus fruits, soft drinks and sports drinks contain high levels of acidity. This acidity is known to cause damage to teeth and can leave nerves exposed making the teeth sensitive.

It would be almost impossible to completely avoid acidic but being aware of how much you are consuming and ensuring you eat a healthy, well balanced diet can reduce the possibility of your teeth becoming sensitive. Using a straw when consuming acidic drinks and avoiding brushing for 30 minutes afterwards can also help.

4. Cavities, Cracked Teeth or Fillings

Overtime fillings can wear out causing the dentin and sometimes nerve to be exposed in the tooth. This will cause pain and sensitivity.  Cavities and cracked teeth can also cause sensitivity and discomfort in the mouth. Regular check-ups and x-rays with your dentist can catch these issues before they become major problems.
