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.
