Sensitive teeth are a very common problem. The teeth are very sensitive to extremes of hot and cold, and sweet and sour foods, and you experience a very sharp transient pain.
The most common cause of sensitive teeth is exposure of the neck of the tooth. The tooth crown is naturally protected from extreme sensations by the tooth enamel, an inert crystalline structure, but the root surface is not. It has a thin layer, the cementum. Beneath the cementum is dentine. It has microscopic tubules that connect with the pulp, which contains blood vessels and nerves.
Aggressive and incorrect toothbrushing can strip the gums back, exposing the root surface, and abrasive toothpaste can quickly wear away the much softer cementum and dentine, allowing unpleasant sensations to be transmitted through to the pulp, causing pain.
The following general advice can be considered:
Denta-Med gel has no abrasive, so it won’t wear the tooth away, and one of the ingredients is zinc chloride, a recognised desensitising agent. Electro microscopy studies have shown blocking of the dentinal tubules by zinc, which would prevent transmission of painful stimuli to the pulp.
