Tooth sensitivity

Sensitive teeth and poor gum health cause pain in one or more teeth. The discomfort begins when your teeth are exposed to an irritant, such as eating or drinking anything extremely hot or cold. Sweets, cold air, broken teeth, and alcohol-containing mouthwashes can cause teeth sensitivity issues, as can cleaning or flossing teeth. This is why it is essential to prevent tooth sensitivity in the first place.

Dentin sensitivity, also known as tooth sensitivity, can be short-lived or long-lasting. Your teeth sensitivity might affect a single tooth, a group of teeth, or even all of your teeth.

Various circumstances cause sensitive teeth. Some unlucky people are more prone to tooth sensitivity because their tooth enamel, the protective outer covering of the tooth, is thinner. Tooth sensitivity can also be caused by activities such as cleaning your teeth with too much force or using a hard bristle toothbrush, grinding your teeth while sleeping, and routinely drinking acidic meals and drinks.

Sensitive teeth after teeth whitening

You may suffer increased sensitivity following a teeth whitening procedure if your teeth are generally sensitive to hot and cold meals and beverages due to weak enamel, gum disease, or tooth decay.

Carbamide peroxide or hydrogen peroxide, in the form of whitening gel or other whitening agents, comes into direct contact with your teeth during dental bleaching agents’ use. These peroxide solutions enter the tooth structure, breaking down and removing stains in the dentin.

Many patients will have whitening agents sensitivity during this procedure, which is just transitory and should disappear within a few days. This teeth sensitivity does not necessarily indicate that you have poor oral health.

In reality, the causes of dental problems with teeth whitening in patients are yet unknown. However, it is thought that the deep penetration of reactive free radicals created by peroxide into the tooth pulp may cause a slight chemical burn and, in turn, make your teeth sensitive. Furthermore, using light sources like a blue LED light in whitening treatments increases pulp temperature, creating additional pain after the process.

Sensitivity of the dentin after whitening

Dentin sensitivity is another type of tooth sensitivity. This is a permanent issue, as opposed to teeth sensitivity from whitening, and occurs when something comes into touch with portions of your teeth with exposed dentin.

When the enamel is weak or your dentin is exposed, the bleaching solution's hydrogen peroxide penetrates your dentin, producing pain, discomfort, and sensitivity. You may suffer increased sensitivity after using a teeth whitening product such as whitening strips or other professional whitening treatment if your teeth are usually abnormally sensitive to cold or hot meals and beverages due to weak enamel.
