What Causes Tooth Sensitivity?

Do you ever feel a sudden painful sensation in your teeth when you drink hot coffee or eat cold ice cream?  Perhaps eating candy or sour foods makes you cringe.  Or maybe simply touching your teeth with a fork or toothbrush makes you jump with pain.  The pain may be mild and tingly or sharp and intense.  These are some of the symptoms of sensitive teeth, known technically as "dentinal hypersensitivity." It is one of the most common dental complaints. 

The pain of dentinal hypersensitivity is not constant - it comes and goes.  Unfortunately, many people do not bring this condition to the attention of their dentists, thinking that it will go away on its own.  However, just when they think it's gone for good, the pain returns.

There are many theories about the causes of tooth sensitivity.  Dental professionals agree, however, that the problem starts when a sensitive part of the tooth called the dentin is exposed.  Dentin is the porous part of the tooth below the enamel. 

  • How does the dentin become exposed?  Some of the ways include:
  • Brushing Too Hard Along The Gumline  
  • Recession Of The Gum  
  • Gum Disease  
  • Periodontal Treatment  
  • Dental Surgery  
  • Fractured Or Chipped Tooth  
  • Tooth Wear At The Gumline  
  • Teeth Clenching Or Grinding, Often During Sleep  
  • Smoking  

What Can You Do About Tooth Sensitivity?

You don't have to suffer from dentinal hypersensitivity.  Here are some ways to help treat your sensitivity:

  • Brush with a desensitizing dentifrice such as Sensodyne Toothpaste - dabbing will not be effective
  • Brush properly - use only a soft bristle toothbrush such as Sensodyne GENTLE
  • Floss carefully
  • Moderate your intake of acidic foods
  • Have regular dental check-ups

If pain persists, your dentist or dental hygienist can help.  Brushing with Sensodyne will help with your sensitive teeth so that you can enjoy hot, cold, sweet, and sour foods. 

Sensodyne works by reducing the nerve impulses which would normally be felt as the pain of sensitive teeth.  The protection builds over time.  It may take up to two weeks before you notice a difference.  Brushing twice a day builds increasing protection against the pain of sensitivity.  Brushing - not dabbing - is the only proven method of relieving tooth sensitivity. 

Your dental professional trusts Sensodyne, which has helped relieve patient's sensitive teeth for more than 30 years.  Visit your dental professional before use and continue to visit for regular check-ups
