Sensitive teeth can turn everyday pleasures like sipping hot coffee or enjoying ice cream into painful experiences. This common dental issue affects millions worldwide, causing sharp, sudden pain when teeth are exposed to certain triggers. Understanding the causes, symptoms, and solutions can help you manage and even overcome tooth sensitivity effectively.
What Causes Sensitive Teeth?
Tooth sensitivity, or dentin hypersensitivity, occurs when the protective enamel layer thins or gums recede, exposing the underlying dentin. Dentin contains tiny tubules that lead to the tooth's nerve center. Common triggers include:
Enamel erosion from acidic foods/drinks (citrus, soda) or aggressive brushing.
Gum recession due to periodontal disease, aging, or overbrushing.
Teeth grinding (bruxism), which wears down enamel.
Recent dental procedures like whitening, fillings, or cleanings.
Cracked teeth or cavities that expose nerves.
Symptoms typically involve short, sharp pain in response to hot, cold, sweet, acidic, or even cold air.
