Caring for St. Williams patients at our office in Port Dover
Every dental service for St. WilliamsThat sudden zing
Sensitivity is a symptom, and the cause shapes the solution.
Tooth sensitivity is a sharp, brief pain triggered by cold, heat, sweet or acidic foods, or even breathing in cold air. It often happens when dentin, the layer beneath enamel, becomes exposed through gum recession, enamel wear or a cracked tooth. Sensitivity can also signal a cavity or a problem with a filling, so identifying the cause is important.
If sensitivity is making it hard to enjoy a cold drink on a summer afternoon near the bay or a hot coffee on a winter morning, St. Williams residents can have their teeth assessed at our Port Dover office and discuss treatment options suited to the cause.
Causes
Several conditions can expose sensitive dentin.
Exposed roots and worn enamel
Gum recession exposes root surfaces that lack protective enamel. Brushing too hard, gum disease and ageing can contribute. Enamel can wear from grinding, acidic foods and drinks or acid reflux. These changes leave dentin more exposed to temperature and touch.
Cracks, decay and dental work
Cavities, cracked teeth, broken or leaking fillings and recent dental work like whitening or new fillings can all cause sensitivity. Sensitivity that lingers, worsens or occurs without a trigger may indicate a nerve problem. These situations need professional assessment.
Assessment
A careful exam helps pinpoint the source.
What the dentist checks
The dentist examines your teeth for recession, wear, cracks and decay, checks existing fillings and may test individual teeth with cold or air. X-rays may be taken. Your brushing habits, diet and grinding are also discussed to understand contributing factors.
Describing your symptoms
Note which teeth are sensitive, what triggers it, how long the pain lasts and whether it is getting worse. Mention any recent dental work. These details help the dentist distinguish simple sensitivity from problems that need more involved treatment.
Treatment
Treatment depends on what is causing the sensitivity.
At-home and in-office measures
Desensitizing toothpaste used consistently can reduce sensitivity over time. Fluoride varnish or other desensitizing agents may be applied in the office. Bonding material can cover exposed root surfaces in some cases. The dentist will recommend what suits your situation.
Treating the underlying cause
If sensitivity is caused by decay, a cracked tooth or a failing filling, treating that problem is necessary. Gum grafting may be discussed for significant recession. If the nerve is inflamed or damaged, root canal treatment may be required.
Prevention
Small changes can reduce sensitivity.
Gentle brushing and diet
Use a soft-bristled brush and gentle technique to avoid wearing enamel and gums. Limit acidic foods and drinks, and rinse with water afterward. Wait a while after acidic meals before brushing. Keep using a desensitizing toothpaste as recommended.
Protecting against grinding
If you grind or clench, a night guard can protect enamel from wear. Treat acid reflux with your physician’s guidance if it affects your teeth. Regular checkups help catch new causes of sensitivity, such as decay or recession, early.

Tooth sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Does sensitive toothpaste really work?
Many people notice improvement after using desensitizing toothpaste consistently for a few weeks. It works best for sensitivity caused by exposed dentin.
Is sensitivity a sign of a cavity?
It can be. Sensitivity may also come from recession, wear or cracks. A dental exam is needed to identify the cause.
Why are my teeth sensitive after whitening?
Whitening can temporarily increase sensitivity. It usually fades after treatment ends. Using desensitizing toothpaste and following instructions can help.
When should I worry about sensitivity?
Sensitivity that lingers, worsens, wakes you at night or occurs without a trigger may indicate a nerve problem. Contact the office for assessment.
Can brushing too hard cause sensitivity?
Yes. Aggressive brushing can wear enamel and cause gum recession, exposing sensitive root surfaces. A soft brush and gentle technique help prevent this.
