What is Hypersensitivity?

Last updated: March 12, 2024

What causes tooth hypersensitivity?

Tooth hypersensitivity, also known as dentin hypersensitivity or sensitive teeth, is a common dental condition that causes discomfort or sharp pain when the teeth are exposed to certain triggers. The primary cause of tooth hypersensitivity is the exposure of dentin, the inner layer of the tooth, which is normally protected by enamel and gums. When the protective layers are compromised, either due to enamel erosion or gum recession, the dentin becomes exposed, allowing external stimuli to reach the nerves inside the tooth, leading to sensitivity.

Enamel erosion can occur due to various factors such as aggressive brushing, acidic foods and drinks, and certain medical conditions that affect enamel formation. Gum recession, on the other hand, can be caused by gum disease, aging, or improper brushing techniques that can wear down the gum tissue and expose the sensitive root surfaces of the teeth.

Other factors that can contribute to tooth hypersensitivity include tooth decay, cracked teeth, teeth grinding, and dental procedures like teeth whitening treatments that can temporarily increase sensitivity.

Tooth hypersensitivity can manifest as a sharp, sudden pain or discomfort when the teeth are exposed to hot or cold temperatures, sweet or acidic foods, or even when brushing and flossing. The sensation can vary from person to person and may be intermittent or persistent depending on the underlying cause.

Managing tooth hypersensitivity often involves addressing the root cause of the problem. Using a soft-bristled toothbrush and practicing proper brushing techniques can help prevent further enamel erosion and gum recession. Avoiding acidic foods and drinks, and using a desensitizing toothpaste containing ingredients like potassium nitrate or fluoride can help alleviate sensitivity by blocking the transmission of nerve signals within the tooth.

In cases where tooth hypersensitivity is severe or persistent, it is important to consult a dentist for a proper evaluation and treatment. Dentists may recommend dental procedures such as applying a protective sealant, bonding, fluoride varnishes, or in more severe cases, a gum graft or a root canal to address the underlying issue and alleviate sensitivity.

Overall, understanding the causes and triggers of tooth hypersensitivity is essential in effectively managing and preventing discomfort. Maintaining good oral hygiene practices, visiting the dentist regularly, and seeking professional advice can help individuals find relief and improve their overall dental health.

Can certain foods or drinks make tooth hypersensitivity worse?

Certain foods and drinks can indeed exacerbate tooth hypersensitivity. Understanding which ones to avoid can help you manage and reduce discomfort.

Acidic foods and beverages like citrus fruits, tomatoes, pickles, and certain carbonated drinks can wear down tooth enamel over time. This erosion exposes the sensitive inner layer of the tooth, called dentin, leading to increased hypersensitivity. If you have sensitive teeth, it's advisable to limit the consumption of these acidic foods and drinks.

Sugary foods and drinks can also contribute to tooth hypersensitivity. Bacteria in the mouth feed on sugars, produce acid, and attack the enamel, making teeth more susceptible to sensitivity. Consuming sugary snacks and beverages frequently can worsen hypersensitivity and increase the risk of cavities.

Hot and cold foods and drinks can trigger discomfort in individuals with hypersensitive teeth. Extreme temperatures can cause nerve irritation, resulting in sharp pain or discomfort. Avoiding very hot or very cold foods and drinks, or consuming them at a more moderate temperature, can help reduce sensitivity episodes.

Abrasive foods like hard candies, ice cubes, and crunchy snacks can cause enamel wear and tear, leading to increased tooth sensitivity. Chewing on hard objects can also chip or crack teeth, exposing dentin and exacerbating hypersensitivity. It's best to avoid or limit the consumption of such abrasive foods to protect your teeth.

Alcoholic beverages can dehydrate the body and reduce saliva production, which plays a crucial role in maintaining oral health. Saliva helps neutralize acids, remineralize enamel, and protect teeth from sensitivity and decay. Reduced saliva flow can make teeth more vulnerable to hypersensitivity and other dental issues.

In conclusion, being mindful of your diet and avoiding or moderating the consumption of acidic, sugary, hot or cold, abrasive, and alcoholic foods and drinks can help manage tooth hypersensitivity.
