Sensitive teeth refer to discomfort or pain in the teeth when exposed to certain stimuli, such as hot, cold, sweet, or acidic foods and drinks. This sensitivity often occurs due to worn enamel, gum recession, or tooth decay, which can expose the underlying dentin. People with sensitive teeth may experience sharp, temporary pain that can be triggered by everyday activities like eating or drinking. Treatment options include using desensitizing toothpaste, fluoride treatments, or dental procedures to address the underlying causes. Maintaining good oral hygiene is essential for preventing sensitivity and protecting overall dental health.
