What is Tooth Sensitivity?
Tooth sensitivity (also called dentin hypersensitivity) occurs when the protective enamel on your teeth wears down or when gum tissue recedes, exposing the underlying dentin. Dentin contains tiny tubes that lead directly to the nerve, and when exposed to temperature, pressure, or sweet stimuli, these tubes allow sensations to reach the nerve — causing sharp, sudden pain.
Sensitivity can range from mild discomfort to severe, debilitating pain that affects daily life. The good news: it is treatable.
Common Triggers
Common Causes of Tooth Sensitivity
Enamel erosion from acidic foods or beverages
Gum recession exposing root surfaces
Tooth grinding (bruxism) wearing down enamel
Aggressive tooth brushing with a hard-bristle brush
Cracked teeth or chipped enamel
Tooth whitening treatments (temporary sensitivity)
Recent dental procedures (scaling, fillings)
Periodontal disease affecting gum tissue
How We Treat Tooth Sensitivity
Our dental hygienists are trained in a variety of desensitization techniques to provide both immediate and long-lasting relief. Treatment is customized based on the severity and cause of your sensitivity.
Fluoride Varnish Application
A professional-strength fluoride varnish is applied to sensitive areas to strengthen enamel and block dentinal tubules, providing immediate pain relief.
Desensitizing Agents
Professional desensitizing gels and agents (such as potassium nitrate or oxalic acid) are applied to calm the nerve and seal exposed dentin surfaces.
Bonding Agent Sealing
For severe sensitivity from recession, a dental bonding agent can be applied to exposed root surfaces to create a protective barrier.
Home Care Recommendations
Your hygienist will advise you on the best desensitizing toothpastes, soft brushing techniques, and dietary modifications to prevent recurrence.
