Teeth sensitivity can be a nuisance, causing discomfort and pain when eating or drinking certain foods and beverages.

Most people think that sensitivity is caused by weak tooth enamel or exposed nerves, but there are other unseen culprits of tooth sensitivity. In this article, we will explore some of these lesser-known triggers and how to prevent and treat tooth sensitivity.

Acidic Foods and Drinks

Some foods and drinks have high levels of acidity that can erode tooth enamel, exposing the sensitive layer of dentin underneath. Examples of acidic foods and drinks include citrus fruits, tomatoes, pickles, wine, coffee, and carbonated beverages.

To avoid sensitivity caused by acidic foods and drinks, it is best to limit their consumption or use a straw to minimize contact with teeth. Rinsing with water after consuming these items can also help neutralize the acid and reduce sensitivity.

Teeth Grinding

Teeth grinding or bruxism can contribute to tooth sensitivity by wearing down enamel and causing hairline cracks in the teeth. Bruxism is often caused by stress or sleep disorders, and may go unnoticed until damage to teeth becomes evident.

To prevent tooth sensitivity caused by bruxism, talk to your dentist about wearing a mouth guard at night or finding ways to manage stress. Treating the underlying causes of bruxism can also reduce the symptoms of tooth sensitivity.

Whitening Products

While teeth whitening products can improve the appearance of teeth, they can also cause sensitivity by removing a layer of protective enamel.

Overuse or misuse of whitening products can result in a thin and weakened enamel layer that exposes the underlying dentin.

To prevent sensitivity caused by whitening products, always follow the instructions carefully and avoid using them too frequently or for extended periods.

If you experience sensitivity, stop using the product and consult with your dentist for alternative options.

Cold Weather

Exposure to cold air or cold drinks can cause temporary sensitivity in teeth, especially for those who already have weakened enamel or gum recession. Cold temperatures can trigger nerve endings in the teeth, causing discomfort and pain.

To prevent sensitivity caused by cold weather, try to breathe through your nose or wear a scarf to cover your mouth. Drinking warm beverages or using a straw to avoid direct contact with teeth can also help prevent sensitivity.

Overbrushing

Brushing your teeth too hard or using a toothbrush with stiff bristles can cause sensitivity by wearing down enamel or pushing back gums. Over time, this can lead to exposed nerve endings and increased sensitivity to hot and cold temperatures.

To prevent sensitivity caused by overbrushing, use a soft-bristled toothbrush and gently brush in circular motions. Avoid using excessive force and switch to a lighter touch if you notice gum recession or enamel erosion.

Cracked Teeth

Cracks or fractures in teeth can cause sensitivity by exposing the sensitive dentin layer or even the pulp inside the tooth. Cracks can occur from trauma, eating hard foods, or from previous dental work like fillings or crowns.

To prevent sensitivity caused by cracked teeth, avoid chewing on hard objects and use caution when eating hard or crunchy foods. Regular dental checkups can also help catch cracks early and prevent further damage.

Gum Disease

Gum disease or periodontitis can cause sensitivity by exposing the root surface of teeth and damaging the supporting tissue. As gum disease progresses, the gums begin to recede, exposing more of the tooth and making it more sensitive.

To prevent sensitivity caused by gum disease, practice good oral hygiene habits like brushing twice a day, flossing daily, and getting regular dental cleanings.

Treating gum disease early can also help prevent more serious complications like tooth loss.

Medications

Some medications can cause tooth sensitivity as a side effect, especially those that affect bone density or cause dry mouth. Examples include bisphosphonates, antihistamines, and some chemotherapy drugs.

To prevent sensitivity caused by medications, talk to your dentist or doctor about any possible side effects and alternative treatment options.

Maintaining good oral hygiene habits and using fluoride toothpaste can also help protect teeth from sensitivity.

High Sugar Diet

A diet high in sugar and carbohydrates can contribute to tooth sensitivity by promoting the growth of bacteria and acid production. This can wear down enamel and increase the risk of cavities and gum disease.

To prevent sensitivity caused by a high sugar diet, limit consumption of sugary and starchy foods and drinks, and opt for healthier alternatives like fresh fruits and vegetables.

Brushing twice a day and flossing daily can also help remove plaque and prevent decay.
