Tooth Sensitivity

Friday, 6 October 2017  |  Admin


Tooth sensitivity affects up to 40% of the population. It is experienced as a painful sensation in the teeth, often occurring after eating or drinking something hot, cold, sweet or acidic.

The tooth comprises of a hard enamel covering a soft dentine layer with an internal nerve. The dentine contains a large number of pores or tubules that run from the outside of the tooth to the central nerve.

Over time, the enamel covering becomes thinner, providing less protection to external stimulation.  The gums can recede and expose unprotected root surface dentine. When the dentine has no enamel protection, the central nerve can be stimulated by changes in temperature and / or certain foods.

Tooth Sensitivity can be caused by:

  • Gum recession, due to age or improper tooth brushing.
  • Drinking acidic beverages, such as soda, which can cause enamel erosion and dentine exposure.
  • Tooth grinding (bruxism) can cause most or all of the teeth to feel sensitive.
  • Brushing with abrasive toothpastes, with incorrect technique or excessively can result in a loss of enamel.
  • A chipped or fractured tooth can cause dentine exposure.
  • Also certain dental treatments can cause tooth sensitivity. Teeth whitening, professional dental scaling, orthodontics or fillings can cause sensitivity, either during or after the procedure.

Te ease teeth sensitivity, we suggest you use BioMinF toothpaste, a new innovation by Queen Mary University, London. BioMinF blocks exposed pores and patients tell us it does so quickly and for longer than other toothpaste.
