Sensitive teeth are a common problem that affects 1 in 3 people, but many of them do not deal with it. A large number of patients try to ignore the sensitivity of their teeth or invent ways to avoid the pain, for example by changing the way they consume certain foods and drinks or even avoiding eating them altogether.

The experts explain: “Teeth sensitivity usually starts at the end of adolescence and if left untreated can take away the enjoyment of certain foods and drinks. That's why people adopt various behaviors to avoid the pain of sensitivity, while the simplest solution to this is to use a toothpaste specially designed for sensitive teeth.

Dentin, the structural material that makes up most of the tooth, is porous, with millions of tiny tubules that end in the nerve of the tooth. A layer of hard enamel, on the crown of the tooth, protects the underlying dentin, but when the dentin is exposed, the tooth becomes vulnerable and can experience sensitivity. This can occur for many reasons, including abrasion from brushing, erosion that breaks down the enamel, or even "grinding" during sleep, which can wear down the enamel. enamel.

When dentin is exposed, temperature changes from hot or cold foods and drinks cause the fluid in its small pores to contract and expand. This process can irritate the nerve and cause sensitive teeth to ache. The sensation of pain varies from a simple discomfort to a sudden sharp pain.
