Dentin hypersensitivity is a common ailment that afflicts millions of people around the world. It is more commonly known as ‘sensitive teeth’. This affliction is characterised by a sharp, shooting pain when one or more teeth are exposed to some kind of external stimulus.
It is most commonly triggered by hot or cold temperatures, but contact with sweet, bitter or sour foods may also trigger it.
Common Causes of Dentin Hypersensitivity
Sensitive teeth may be caused by a variety of factors:
Veneers – Getting veneers in places such as Liverpool is usually a pain free experience. English dentistry is highly developed due to the widespread availability of sedatives and painkillers. However, some patients may experience tooth sensitivity after the application of veneers.
Veneers are porcelain tooth covers that require partial enamel removal to adhere them to existing teeth. When dentists scrape away the enamel, it exposes the dentin, which is sensitive to temperature changes.
Dentin is the second layer of material that comprises the teeth. Enamel is the top layer, followed by dentin and, finally, the pulp. Since dentin is so close to the pulp, you experience a sharp pain in the tooth whenever it is stimulated.
Gingivitis – Another cause of sensitive teeth is gingivitis. This disease inflames the gums, causing it to contract the skin. The swollen skin exposes the dentin close to the roots, leading to sensitivity.
Bruxism – Bruxism, also known as teeth grinding, wears down the enamel and contributes to sensitive teeth.
Tooth Decay – Tooth decay likewise exposes the dentin, leading to hypersensitivity.
It is possible to reduce hypersensitivity. One of the most effective ways to reduce pain associated with sensitive teeth is to improve dental hygiene. The regular use of fluoride-based oral products strengthens the enamel and limits dentin exposure.
Treating the underlying causes of tooth sensitivity is helpful, but preventative measures are more effective. The goal is to keep the enamel healthy to prevent the sensitive dentin from becoming exposed.
