What Causes Tooth Sensitivity?
Tooth sensitivity occurs when the protective outer layer of the tooth—called enamel—becomes thinner or when gums recede, exposing the underlying dentin layer. Dentin contains microscopic tubules that connect to the tooth’s nerve. When exposed to temperature changes or certain foods, these tubules transmit signals to the nerve, causing discomfort.
Common Causes of Sensitive Teeth
Some of the most common causes include aggressive tooth brushing, gum recession, tooth decay, worn dental fillings, teeth grinding (bruxism), acidic foods and drinks, and whitening treatments.
What Can Help Reduce Sensitivity?
Using desensitizing toothpaste can help block nerve pathways that cause sensitivity. Switching to a soft‑bristled toothbrush and avoiding aggressive brushing can protect enamel. Limiting acidic foods and beverages can also help prevent enamel erosion.
When Should You See a Dentist?
If sensitivity persists for more than a few weeks, it is important to consult a
dentist. Sometimes sensitivity may indicate deeper problems such as tooth decay, a
cracked tooth, or gum disease.
Persistent symptoms should always be evaluated by a dental professional. Clinics
like Amelia Street Dental focus on early diagnosis and preventive treatment, helping
patients manage dental issues before they become more complex.
