That sharp, momentary pain when you bite into ice cream or sip hot coffee is something many people simply put up with. But tooth sensitivity is almost always treatable — and sometimes it is a sign of a more serious underlying problem that should be addressed.
What Causes Tooth Sensitivity?
Sensitivity occurs when the inner layer of the tooth (dentin) becomes exposed. This can happen through enamel erosion from acidic foods or drinks, gum recession exposing the tooth root, aggressive brushing that wears down enamel, cracked teeth that expose the inner structure, or tooth whitening.
Distinguishing Sensitivity from a Dental Problem
Mild, brief sensitivity to cold that resolves within a few seconds is often benign. However, sensitivity that is severe, prolonged, or triggered by heat rather than cold can indicate a deeper problem such as tooth decay, a cracked tooth, or an infected pulp that may require root canal treatment.
Treatment Options
Treatment depends on the cause. Sensitivity toothpastes containing potassium nitrate or stannous fluoride can help mild cases. Fluoride varnishes applied in-office strengthen enamel and reduce sensitivity. If recession is the cause, gum grafting may be recommended. Cracked or decayed teeth require restorative treatment.
What You Can Do at Home
Switch to a soft-bristled toothbrush and use a gentle technique. Limit acidic beverages and rinse with water after consuming them. Use a fluoride toothpaste and consider sensitivity toothpaste as an add-on. If sensitivity persists for more than a week or is severe, book an appointment at Smileworks Dental for a proper evaluation.
