Dentine Hypersensitivity

Dentin hypersensitivity is a common dental health problem for many individuals. It is characterized by short, sharp pain in response to stimuli such as cold, sweet, or sour food or beverages, air, or even brushing. The pain is caused by the exposure of the nerve endings in the dentin layer of the tooth. Dentin is found beneath the enamel and cementum of the tooth, and it contains thousands of tiny nerve endings. These nerve endings can be stimulated when the dentin is exposed due to receding gums, dental erosion, or worn enamel. When that happens, a person can experience sharp and uncomfortable sensitivity. People most likely to experience dentin hypersensitivity are those who have worn enamel, gingivitis or periodontitis, gum recession, and high levels of acidity in the mouth from a poor diet. The pain from dentin hypersensitivity is usually temporary, but the underlying cause should still be addressed. Fortunately, there are treatments available to help manage dentin hypersensitivity. The most effective treatment is a fluoride agent that reorganizes the dentin and blocks exposed tubules, thereby reducing the transmission of the sensation of pain. Some over the counter rinses, toothpastes, and creams also contain ingredients such as potassium nitrate or strontium chloride, which are meant to desensitize the nerve endings. For more severe cases, a dentist may recommend a dental bonding procedure or veneer to treat exposed dentin. In addition, the dentist may suggest avoiding acidic foods that corrode the enamel, and they may recommend the patient wear a night guard during sleep to protect the teeth from grinding forces. Dentin hypersensitivity can be excruciating, but with the right combination of at-home treatments and professional care, it doesn't have to be a lingering part of life. From routine cleanings to professional fluoride treatments, there are a number of ways to understand, manage, and minimize dentin sensitivity.
