Why are my teeth suddenly sensitive? Understanding sudden onset tooth sensitivity

Enamel erosion

Enamel erosion is a frequent cause of tooth sensitivity. Enamel is the hard outer layer of the teeth that protects the softer dentin underneath. When enamel erodes, dentin becomes exposed. This exposure makes teeth more sensitive because dentin contains tubules that connect directly to the tooth’s nerve.

Causes of enamel erosion:

• Acidic foods and drinks: Regular consumption of acidic items like citrus fruits, soda, and wine weakens enamel.
• Aggressive brushing: Using too much force or a hard-bristled toothbrush can wear down enamel over time.
• Gastroesophageal reflux disease: Stomach acid from acid reflux can reach the mouth, contributing to enamel loss and increased sensitivity.

Gum recession

Gum recession occurs when the gum tissue pulls back, exposing the roots of teeth. Unlike the enamel-protected crowns, roots lack this defense, making them highly sensitive to external stimuli like temperature and sugary foods.

Causes of gum recession:

• Periodontal disease: Advanced gum disease damages the supporting gum tissue, leading to recession.
• Improper oral hygiene: Inadequate brushing and flossing cause plaque buildup, inflaming gums and eventually leading to gum loss.
• Bruxism: Clenching or grinding teeth puts pressure on gums, potentially leading to recession.

Tooth decay

Cavities form when tooth enamel is damaged by bacteria or acids, and they can cause sudden sensitivity. Once decay penetrates the enamel and reaches the dentin, teeth become more sensitive to hot, cold, or sweet foods. Poor oral hygiene, excessive sugar intake, and irregular dental visits increase the risk of tooth decay.

Cracked or damaged teeth

Cracks or chips in teeth can expose dentin or even the tooth’s nerve, leading to sensitivity. These cracks may result from trauma, chewing on hard items, or excessive teeth grinding. Sometimes cracks are too small to see, making it difficult to pinpoint the issue without a dentist’s examination.

Recent dental procedures

Teeth may feel sensitive after dental procedures such as fillings, crowns, or whitening treatments. This sensitivity is usually temporary and results from the disturbance of tooth structure during the procedure. In most cases, the discomfort subsides within a few days or weeks. However, if sensitivity persists, it’s important to visit your dentist to address the issue.

Managing tooth sensitivity

Identifying the root cause of sudden tooth sensitivity can help you with targeted treatments. Your dentist can help you address issues such as enamel erosion, gum recession, and tooth decay. Simple changes, such as using desensitizing toothpaste, gentle brushing, and avoiding acidic foods, can make a significant difference.

Looking for sensitive teeth solutions?

Explore our products. Sensodent-K contains potassium nitrate, which helps to reduce the sensitivity related pain. However, if you are looking for a SensodentK toothpaste for cavity protection and to resolve sensitivity discomfort, check Sensodent KF. It has both potassium nitrate and fluoride. The fluoride helps prevent cavities by remineralizing the enamel layer.
