ToothacheTooth sensitivity is a condition characterized by a tingly feeling or a flash pinch of pain affecting all teeth, certain areas of certain teeth or all of one or more teeth.

The pain associated with tooth sensitivity may occur constantly or intermittently. Intermittent tooth sensitivity can occur while ingesting hot or cold food or beverages, or when cold air hits the teeth.

The Cause of Tooth Sensitivity
  • Aging accounts for some tooth sensitivity. Enamel (the outer tooth surface) naturally wears down, exposing the dentin (the initial inner tooth surface) and causing sensitivity.
  • Gum recession and gum disease (periodontitis), or a chipped or fractured tooth.
  • Acidy liquids (soda), cause enamel wear and dentin exposure.
  • Tooth grinding.
  • Brushing teeth too hard, cause enamel loss and dentin exposure.
  • Dental treatment: teeth whitening, professional dental hygiene cleanings, orthodontics or tooth restorations.
  • Root nerve damage.
Dentist Check UpDentist Check Up
Dentist will check the cause of sensitivity teeth. Dentist uses an instrument called a spray gun to dispense air across every area of each tooth in order to locate the sensitivity.

Once it is determined that the cause does not require dental restorative treatment, your dentist may apply an in-office desensitizer (acts as protective coating). The product is applied by dentist while you are in the office. Desensitizers may also be used to reduce discomfort during dental treatments.

Treatment of Tooth Sensitivity

Low-level sensitivity
Sensi Blok
Home maintenance program can be effective: Over-the-counter fluoride rinses, gels and toothpastes can make the root nerve less sensitive or build a protective coating to cover the tooth surface.

Higher levels of sensitivity
An office desensitizer may provide relief for many months, even years.
Sometimes, dentists recommend an over-the-counter desensitizer to supplement treatment. A soft-bristled toothbrush may also provide relief.
