Sensitivity is a symptom with more than one possible source.
Tooth sensitivity is a sharp, brief discomfort triggered by cold, heat, sweets, acidic foods or even cold air. It often happens when the protective enamel wears down or gums recede, exposing the softer dentin beneath. But sensitivity can also signal a cavity, a cracked tooth, a leaking filling or gum disease. Finding the cause guides effective treatment.
If you are in Nixon and your teeth have become sensitive, book an assessment at our Port Dover office. The dentist will examine the affected teeth, ask about your habits and explain the likely cause. Treatment may be as simple as a change in toothpaste or may involve repairing a tooth.
Describe it
Your description helps narrow the cause.
Triggers and patterns
Note which teeth are sensitive, what triggers the discomfort and how long it lasts. Brief sensitivity to cold that fades quickly often relates to exposed dentin. Pain that lingers, throbs or wakes you at night may suggest a deeper problem with the nerve. Sensitivity when biting can indicate a crack. Share these details at your appointment.
Habits that may contribute
Brushing too hard, using a hard-bristled toothbrush, grinding your teeth, frequent acidic drinks and recent whitening can all contribute to sensitivity. Mention any of these habits, along with recent dental work. Some sensitivity after fillings or cleanings is normal and fades. Knowing your routine helps the dentist suggest practical changes that make a real difference.
Finding the source
The dentist looks for what is exposing the nerve.
Examining teeth and gums
The dentist examines the sensitive teeth for worn enamel, gum recession, exposed roots and decay. They may gently test teeth with air or cold to locate the source. Your bite may be checked for signs of grinding. Existing fillings and crowns are examined for leaks or cracks that could let temperature changes reach the inside of the tooth.
Ruling out other problems
X-rays may be taken to look for cavities between teeth, problems under fillings or signs of nerve inflammation. If a crack is suspected, additional tests may be used. Ruling out these issues is important, since they need different treatment than simple sensitivity. The dentist will explain the findings and what they mean before recommending care.
Treatment options
Treatment depends on the cause.
At-home and in-office desensitizing
For mild sensitivity from exposed dentin, a desensitizing toothpaste used consistently for several weeks may help. The dentist may apply fluoride varnish or a desensitizing agent in the office to strengthen enamel and reduce discomfort. Switching to a soft toothbrush and gentler technique can prevent further wear. These measures are simple and often effective for mild cases.
Repairing the underlying problem
If sensitivity is caused by decay, a cracked tooth or a leaking filling, the dentist will recommend repairing the problem. Exposed root surfaces may be covered with bonding. For gum recession, gum treatment or referral may be discussed. If the nerve is inflamed, root canal treatment may be needed. The dentist will explain why each option is recommended.
Preventing it
Small changes can reduce sensitivity over time.
Gentle daily habits
Use a soft-bristled toothbrush and gentle, circular strokes along the gumline. Avoid scrubbing back and forth. Keep using a desensitizing toothpaste if recommended. Clean between teeth daily to prevent gum problems that could expose roots. If you grind your teeth, ask about a night guard to protect enamel from wear and cracking while you sleep.
Protecting enamel
Limit acidic foods and drinks like citrus, soda and sports drinks, and avoid brushing immediately after consuming them, since enamel may be softer. Rinse with water instead. Keep regular checkups so the dentist can monitor sensitive areas and catch new problems early. Report sensitivity that worsens or changes in character rather than waiting for your next visit.
Planning your appointment
Get sensitive teeth checked from Nixon.

Sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Why are my teeth suddenly sensitive?
Sudden sensitivity can be caused by a cavity, a cracked tooth, a lost filling, gum recession or recent whitening. Since some causes need treatment, have new or worsening sensitivity checked by the dentist rather than assuming it will pass.
Does sensitive toothpaste really work?
For many people with mild sensitivity from exposed dentin, desensitizing toothpaste can help when used consistently for several weeks. It does not treat cavities or cracks, so have persistent sensitivity assessed. Spitting rather than rinsing after brushing may help the active ingredient work.
Can brushing too hard cause sensitivity?
Yes. Aggressive brushing or a hard-bristled toothbrush can wear enamel and push gums back, exposing sensitive root surfaces. Switching to a soft brush and gentle technique can help prevent further wear. The hygienist can check your technique.
Is sensitivity after a filling normal?
Some sensitivity to cold or pressure after a filling is common and usually fades within days to a couple of weeks. If it persists, worsens or your bite feels uneven, contact the office for a check.
Can gum recession be reversed?
Lost gum tissue does not usually grow back on its own. Gentle brushing and gum care can help prevent further recession. In some cases, bonding or gum treatment may be discussed to cover exposed roots and reduce sensitivity.
