What is Tooth Sensitivity?

The first type is called Dentinal sensitivity, caused by exposure of the dentin of a tooth (the outher protective layers of enamel). Normally, the dentin is covered by enamel above the gumline and by cementum below the gumline. When the dentin is exposed, cold or hot temperature or pressure can affect these nerve branches.

  • Brushing your teeth too hard.
  • Poor oral hygiene.
  • Long-term tooth wear
  • Untreated cavities
  • An old filling with a crack or leak
  • Receding gums that expose the tooth's roots. Please also refer to periodontal diseases section for more details.
  • Gum surgery that exposes a tooth's roots
  • Tooth whitening in people who have tooth roots that already are exposed
  • Frequently eating acidic foods or drinking acidic beverages

The second type is known as Pulpal sensitivity, which is a reaction of the tooth's pulp. The pulp is a mass of blood vessels and nerves in the center of each tooth. Pulpal sensitivity tends to affect only a single tooth.

The causes of pupal sensitivity include:

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

Treatment Options

For Dentinal sensitivity, the followings may be recommended to relieve the symptoms:

  • Professional Cleaning
  • Using a soft or ultrasoft toothbrush and brushing gently up and down, rather than side to side
  • Using a fluoride toothpaste and mouth rinse
  • Using a toothpaste that provides protection against sensitivity
  • Getting treatment for grinding or clenching your teeth (bruxism)

Pulpal sensitivity will be treated with a Root Canal Therapy if the tooth's nerve is damaged or dying.
