Fort Worth Dentist What Causes Tooth Sensitivity Powered By Docstoc
					Tooth sensitivity or sensitive teeth is most frequently caused by dentin
exposure.Dentin is the primary substance of your tooth, which surrounds the pulp and
contains small pores that lead directly to your tooth's nerve. Dentin is covered by
enamel in the unseen parts of the tooth while the part you see is covered by the gum
under healthy conditions.

 In instances where you experience sensitivity, probably is because the enamel has
worn out or the gum has receded. The best way to explain sensitivity is sharp, sudden,
shooting pain. A sensitive tooth can be felt inside the nerve ending. Constant or
sporadic pain is what you endure. Exposure of the dentin to the outside environment
for instance gum recession or missing of the enamel will cause sensitivity.

 Dehydration of teeth causes sensitivity too and this happens if you use whitening or
bleaching agents.This is temporary as the sensitivity dissipates as re-hydration occurs.
Those suffering from dry mouth are victims too who suffer from sensitivity because
of insufficient saliva flow to neutralize bacterial or food acids.

 Whitening of teeth is popular and is done to improve appearance. But some people
feel the sensitivity after the procedure even though it is safe and effective. Other
causes that lead to heat or cold sensitivity in teeth is bleaching agents. As a matter of
fact, heat and cold will constantly cause sensitivity to the extent that even breathing
cold air is agonizing.

 Other good examples of sensitivity in teeth are fillings that use gold crowns, inlays
and amalgam because they are good temperature conductors.The scenario worsens if
the cavity is deep and close to the nerve (pulp) causing intermittent pain. For cracked
or broken teeth seek medical help to have them fixed. Left untreated, the pulp
becomes exposed, bacteria from the mouth finds its way to the pulp causing infection
and toothache.

Teeth erosion is a major contributor to sudden sensitivity as dietary acids from intake
of fruit juices, carbonated soft drinks, and sucking of citrus fruits dissolves away tooth
substance. Posterior surfaces are eroded by gastric acid and this can be noted in
patients who have anorexia, bulimia or are alcoholics.Tooth with erosions normally
has symptoms of scooped out appearances.

 The correction of misalignment of teeth which is called orthodontic is one more
cause of dental sensitivity because of pressure induced appliances. Sometimes during
the placement of tooth straightening the slightest force could induce sensitiveness.All
forms of treatment are designed to seal the microscopic tubules or the dentin pores
thereby preventing nerve irritation and sensitivity. To help in sealing the dentin pores,
regular use of toothpaste with potassium nitrate or a prescription of fluoride has
proven benefits. Beware of the usage of all this desensitizing agents as they only cater
for the symptoms and not the root cause of the sensitivity.
Treatment would include a thorough dental evaluation and treatment of any cavities
and/or gum disease. Sensitivity caused by clenching or grinding of teeth can be solved
by wearing a night guard.

  Preserving your outer tooth structure in this case the enamel, is the best way to get
rid of sensitivity and when symptoms begin to show, use desensitizing toothpaste.
