Common Causes of Tooth Sensitivity

Millions suffer from tooth sensitivity. Hot, cold, sweet, or acidic meals, drinks, and air can trigger severe tooth sensitivity. Dental diseases, lifestyle factors, and other health conditions might cause the illness. Let’s delve into the typical tooth sensitivity causes.

Gum Recession

When gum tissue pulls away from teeth, the root becomes exposed. Because the root is not protected by enamel, hot and cold foods and beverages irritate it and cause pain. Gum recession can be brought on by genetics, rigorous brushing, and periodontal disease.

Tooth Decay

Tooth decay happens when mouth bacteria produce acid that weakens or eats away the enamel, making teeth sensitive to hot, cold, and sweet foods. Neglecting it can lead to cavities and tooth loss. Brushing twice a day and flossing can prevent tooth decay and sensitivity. If these problems persist further, it is important to consider dental restorations from our dentist.

Tooth Grinding

This is also called bruxism. Bruxism is when someone grinds or clenches their teeth unconsciously, often during sleep, wearing down enamel and causing sensitivity. Stress, anxiety, and sleep disorders can cause bruxism. A custom mouthguard from Mission Hills Dental can alleviate sensitivity caused by bruxism.

Acidic Foods and Drinks

Acidic foods and drinks like citrus fruits and soda can wear down the enamel, causing tooth sensitivity. Acid softens enamel, exposing sensitive layers. To prevent sensitivity, limit consumption and rinse with water after consuming acidic foods and drinks.

Teeth Whitening and Other Dental Procedures

Whitening teeth is a trendy dental procedure that can lead to sensitivity. Chemicals used can weaken enamel, causing sensitivity to hot, cold, and sweet foods. Sensitivity resolves after a few days, but using desensitizing toothpaste and avoiding hot or cold foods can ease discomfort.

Tooth sensitivity can also result from fillings, crowns, and root canals, among other dental operations. These procedures have the potential to irritate and inflame the pulp, the soft tissue inside the tooth, which leads to increased tooth sensitivity. After the dental procedure, the sensitivity normally goes away within a few days or weeks. But, it’s crucial to get in touch with your dental practitioner if the sensitivity lasts or worsens so that they can determine what’s causing the tooth sensitivity.


Our teeth’s natural enamel wears down with age, exposing the sensitive tooth layers. This may result in tooth sensitivity and increase a person’s risk of developing dental problems, including cavities and gum disease. Tooth sensitivity and other aging-related dental issues can be avoided by practicing basic oral hygiene and scheduling routine checkups with your dentist.
