WHY ARE MY TEETH SENSITIVE?

One of the most common problems facing patients as well as Dentists is the treatment of sensitive teeth.

Many times patients will present issues of hot, cold, sweet or sour discomfort.  As the population is aging and people are retaining their teeth much longer than before, these issues are becoming more prominent.

One of the main reasons for sensitive teeth is due to what is called recession.  Recession is basically the natural shrinkage of the gum tissue around the neck of the tooth.  As this occurs the root surface becomes more exposed to external stimuli namely hot or cold liquids or foods.  When the hot or cold stimuli contact these surfaces, patients may experience mild to severe sensitivity,  “feels like a nerve is exposed” comments are often mentioned.   To combat these issues, sensitive type toothpastes and rinses have been developed to curb these problems.  In many cases they aid in lessening the sensitivity.

Secondly, sensitivity may be due to hairline cracks or fracture of the outer enamel of teeth.  Patients usually state that their teeth hurt when heavy chewing is applied to one or more teeth.  This may indicate a fracture.  If this is only minimal, a cap or crown may be needed to cover the tooth to help prevent further fracturing.

Thirdly, sensitivity may be due to excessive brushing with a hard bristle brush.  Many patients feel that the harder they scrub or brush the cleaner the teeth.  What this causes is erosion or wearing away of the root surface of the tooth.  A “ditching” of the root can occur.  A bonded type filling will then be placed to build-up the worn away surface.  This idea is contraindicated.  It is recommended to brush with a soft bristle brush with little pressure. Brush longer for at least 3 minutes. This technique is much more safe and effective.  There are many battery-powered toothbrushes on the market that are great for this reason.  The Sonicare, the Oral-B Braun and the Crest spin brush are among the top sellers.  These units offer soft bristle heads and the control of less pressure on the teeth.

In Conclusion, one can see there are many causes for sensitivity with teeth.  To be sure, patients should seek the care and advise of their Dentist for the proper diagnosis and treatment.
