Despite the fact that dental science has evolved and the number of oral hygiene products has skyrocketed, there is an increase in dental hypersensitivity in the global population, becoming a common dental problem.
Dental hypersensitivity is manifested by the appearance of a characteristic short, strong pain and severe discomfort when chewing, when swallowing food and liquids, especially if they are very hot or very cold. In fact, this acute pain manifests itself in some cases even when cold air enters the oral cavity.
In hypersensitive teeth, the pain is intense, sudden and the patient feels it deeply, up to the nerve endings of the teeth. In some cases it subsides or disappears after a few weeks due to the normal blockage of the dentinal tubules, while in others, it turns into a chronic condition.
Dental hypersensitivity develops gradually, as a result of common problems, but when the problem is located in the area of the neck of the tooth, where the molar of the tooth joins the root, the condition is characterized as cervical sensitivity.
Dental hypersensitivity has the following causes:
- The consumption of acidic foods and drinks, which cause the erosion of the tooth, the erosion of the dentin, the dissolution of the natural blockage of the dentinal tubules, and even the prevention of the formation of dentin.
- The incorrect way of brushing that causes tooth abrasion.
- The neglect of dental hygiene.
- Teeth grinding, which leads to wear of the enamel.
- Periodontitis or receding gums.
- Caries, which due to the destruction of enamel leads to the exposure of dentin to the external environment.
- The cracked/broken tooth syndrome which causes the transmission of external stimuli to the nerve endings of the dentine.
- Uncontrolled teeth whitening, which can cause chemical erosion of the teeth when applied regularly or even in excessive dosage, without the dentist’s control.
- Specific dental intervention, such as teeth cleaning and fillings. In these cases the sensitivity is temporary and lasts a few days or weeks.
Tooth sensitivity is treated during a visit to the dentist, who is able to apply the appropriate treatment so that the pain subsides as soon as possible. However, there are specific products that are applied in the dental office but allow the patient to be able to continue his treatment at home (following the dentist’s recommendation) using products in the form of gel or toothpaste.
Finally, to avoid future problems in patients with sensitive teeth, it is very likely that some simple changes in their daily oral care and eating habits will need to be made.
