Some people suffer sharp bouts of pain especially when they take cold food or drinks into their mouths. This condition – known as cervical dentine sensitivity – is a result of exposure of the root surface at the gum margin due to gingival recession, gum disease or over-vigorous toothbrushing with a hard toothbrush. The condition can be quite distressing.
Precautions outlined above to prevent gum disease and tooth abrasion will also help reduce the incidence of cervical dentine sensitivity. In severe cases, the advice of a dentist should be sought. To alleviate the sensitivity, the dentist may decide to apply a high concentration fluoride varnish on the site. It is worth noting that tooth sensitivity can also be due to other reasons such as a loose or cracked filling, hence the importance of seeking dental advice. The oral health care industry has responded to the increased prevalence of cervical dentine sensitivity and a number of “sensitivity” toothpastes formulated to alleviate pain from cervical dentine sensitivity are currently on the market.
