Tooth Sensitivity Treatment


Two types of tooth sensitivity are: Dentinal sensitivity, Pulpal sensitivity

Dentinal sensitivity occurs when the dentin(middle layer) of a tooth is exposed. Normally, the dentin is covered by enamel above the gumline and by cementum below the gumline. Dentin contains tiny openings called tubules.

Inside each tubule lies a nerve branch that comes from the tooth’s pulp (the nerve center of the tooth). When the dentin is exposed, cold or hot temperature or pressure can affect these nerve branches. This causes sensitivity.

Pulpal sensitivity is a reaction of the tooth’s pulp. The pulp is a grouping of blood vessels and nerves in the centre of each tooth.


Dentinal sensitivity  You might be able to reduce your chances of dentinal sensitivity by:

  • Using a fluoride toothpaste and mouthwash.
  • Brushing twice a day and flossing daily.
  • Using a toothpaste that provides protection against sensitivity.
  • Using a soft or ultra-soft toothbrush and gently brushing up and down.
  • Filling worn away surfaces due to hard brushing
  • Removing all calculus and tartar that exposes root surfaces by creating pockets between gums and teeth
  • Placing onlays or crowns over excessively worn tooth surfaces
  • Replacing old/damaged fillings
  • Reducing intake of acidic food and drinks

 Many of us say we have “sensitive teeth.” We usually mean that we feel pain or discomfort in our teeth in certain situations.

These may include:

  • Eating or drinking cold things.
  • Eating or drinking hot things.
  • Eating sweet things.

Dentin Exposure  When the dentin becomes exposed when the outer protective layers of enamel or cementum wear away. This can affect one or more teeth. Some causes of dentin exposure include:

  • Brushing your teeth too hard can wear away the enamel layer.
  • Poor oral hygiene.
  • Long-term tooth wear
  • Untreated cavities
  • An old filling with a crack or leak
  • Frequently eating acidic foods or drinking acidic liquids

Pulpal sensitivity  Pulpal sensitivity tends to affect only a single tooth. Causes include:

  • Decay or infection
  • A recent filling
  • Excessive pressure from clenching or grinding
  • A cracked or broken tooth
