Sensitivity is a symptom, and finding its cause is the first step to relief.
A short, sharp pain when you sip something cold, bite into ice cream or brush near the gumline is a common complaint. Tooth sensitivity often happens when the inner layer of the tooth, called dentin, becomes exposed through gum recession, worn enamel or cracks. Cavities, leaking fillings and recent dental work can also cause it. Each cause calls for a different approach.
If you live in Normandale and sensitive teeth are making meals or cold drinks uncomfortable, our Port Dover dentist can examine the affected teeth and explain what is causing the problem. We will suggest treatments ranging from simple home care to in-office options.
Common causes
Several factors can expose the sensitive inner tooth.
Exposed roots and worn enamel
Gum recession exposes root surfaces, which lack the protective enamel found on the crown. Brushing too hard, gum disease and ageing contribute to recession. Acidic foods and drinks, reflux and grinding can wear away enamel, exposing dentin. These changes often develop gradually over years.
Decay, cracks and dental work
Cavities, cracked teeth and fillings with gaps can let temperature changes reach the nerve. Sensitivity may also follow fillings, cleanings or whitening, usually settling with time. Persistent or worsening sensitivity, especially to heat or lingering after the trigger, may indicate a deeper problem.
Assessment
Details about your pain help guide the diagnosis.
Describing your symptoms
Note which teeth are sensitive, what triggers the pain and how long it lasts. Brief pain that stops when the trigger is removed is common with exposed dentin. Pain that lingers or occurs without a trigger may suggest nerve inflammation and needs closer evaluation.
Examination and x-rays
The dentist examines the teeth and gums, checks for recession, wear, cracks and decay and may use cold or air to test sensitivity. X-rays help detect hidden cavities and problems around roots. Identifying the cause allows treatment to be targeted effectively.
Treatment
Treatment ranges from toothpaste to restorations.
Home care and desensitizing products
Desensitizing toothpaste used consistently over several weeks can reduce sensitivity for many people. A soft toothbrush and gentle technique help prevent further recession. Limiting acidic foods and drinks and waiting before brushing after acidic meals can protect enamel.
In-office treatments
Fluoride varnish, bonding agents or sealants can be applied to sensitive areas. Fillings may repair decay or cover exposed roots. Gum grafts may be considered for significant recession. If the nerve is irreversibly damaged, root canal treatment might be needed. The dentist will explain the options.
Prevention
Protecting enamel and gums helps prevent sensitivity.
Daily habits
Brush gently with a soft brush and fluoride toothpaste, using small circular motions. Avoid aggressive scrubbing. Rinse with water after acidic foods and drinks, and use a straw for acidic beverages where practical. If you grind your teeth, ask about a night guard.
Regular review
Regular checkups allow the dentist to monitor recession, wear and restorations. Report new or worsening sensitivity, as it may signal a change that needs attention. Early treatment of decay and gum disease helps prevent sensitivity from becoming a bigger problem.

Tooth sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Does desensitizing toothpaste really work?
Many people notice improvement after using it consistently for several weeks. It works best for sensitivity caused by exposed dentin.
Is sensitivity a sign of a cavity?
It can be, but it may also come from recession, worn enamel or cracks. An examination helps identify the cause.
Why are my teeth sensitive after whitening?
Whitening can temporarily irritate the nerve. Sensitivity usually fades after treatment. Desensitizing toothpaste may help.
Can brushing too hard cause sensitivity?
Yes. Aggressive brushing can wear enamel and contribute to gum recession. Using a soft brush and gentle technique helps protect teeth.
When should I worry about sensitivity?
Pain that lingers, occurs without a trigger, is severe or worsens over time should be checked promptly, as it may signal a nerve problem.
