Tooth sensitivity is caused by a number of factors, but typically it's the result of worn tooth enamel or exposed tooth roots. It can also be caused by a cavity, a cracked or chipped tooth or indeed gum disease. Tooth discomfort and pain can be triggered by a number of stimuli, notably hot and cold food and drinks and or cold air. This tooth sensitivity is a result of exposure of the root surface at the gum margin due to gum recession, gum disease or over-vigorous toothbrushing with a hard toothbrush. The condition can be quite distressing.
Precautions outlined by us to prevent gum disease and tooth abrasion will also help reduce the incidence of tooth sensitivity. In severe cases, the advice of a dentist should be sought. To ease the sensitivity, the dentist may decide to apply a high concentration fluoride varnish on the site. Tooth sensitivity can also be due to other reasons, hence the importance of seeking dental advice. The oral health care industry has responded to the increased occurence of tooth sensitivity and a number of “sensitivity” toothpastes formulated to alleviate pain are currently on the market.
