Every dental service for Silver HillRelief from the sharp zing
Sensitive teeth usually have an identifiable cause.
Tooth sensitivity happens when the inner layer of the tooth, called dentin, becomes exposed. Dentin contains tiny channels that lead to the nerve, so cold, heat, sweets, acidic foods or even air can trigger a sharp, brief pain. Common causes include gum recession, worn enamel, grinding, cracked teeth, cavities and recent dental work or whitening.
Silver Hill patients who notice sensitivity can have their teeth assessed at our Port Dover office. The dentist will look for the cause, rule out problems such as decay or cracks that need treatment, and recommend ways to reduce sensitivity, from toothpaste changes to in-office treatments.
Finding the cause
Understanding the cause guides the right treatment.
Common causes of sensitivity
Gum recession exposes root surfaces that lack protective enamel. Enamel can wear from aggressive brushing, acidic foods and drinks or grinding. Recent whitening or dental work can cause temporary sensitivity. Some people simply have more sensitive teeth than others. The dentist will look for these factors during the examination.
When sensitivity signals something more
Sensitivity that lingers after the trigger is gone, occurs with biting, or is focused on one tooth may indicate a cavity, cracked tooth, leaking filling or inflamed nerve. These problems usually need dental treatment rather than simple sensitivity relief. Mention exactly when and where you feel sensitivity so the dentist can pinpoint the cause.
Assessment
A careful exam rules out problems that need repair.
Checking teeth and gums
The dentist examines your teeth for decay, cracks, worn enamel and leaking fillings, and checks your gums for recession and inflammation. X-rays may be taken to look for hidden problems. The dentist will also ask about your brushing habits, diet, whitening and any grinding or clenching.
Testing the sensitive area
The dentist may apply a gentle stream of air or cold to identify which teeth are sensitive and how strongly they respond. Tapping or biting tests can help detect cracks. These steps help separate general sensitivity from problems that need specific treatment, such as a filling or crown.
Treatment options
Several approaches can reduce sensitivity.
At-home relief
Toothpaste designed for sensitive teeth can help block the channels in dentin or calm the nerve over a few weeks of regular use. Brushing gently with a soft brush and avoiding very acidic foods and drinks can help protect enamel. A fluoride rinse may also be recommended.
In-office treatments
The dentist may apply fluoride varnish or desensitizing agents to sensitive areas. Bonding can cover exposed roots. If gum recession is significant, a referral for gum grafting may be discussed. A night guard can help if grinding is contributing. Cavities or cracks are treated with fillings, crowns or other repairs.
Preventing sensitivity
Good habits help keep sensitivity from returning.
Protecting enamel and gums
Brush gently with a soft-bristled brush, using small circular motions rather than scrubbing. Limit acidic foods and drinks, and rinse with water after having them. Wait a while after acidic food before brushing. Use fluoride toothpaste daily, and consider a sensitivity toothpaste if recommended. Give any new product a few weeks to work.
Ongoing monitoring
Keep regular checkups so the dentist can monitor gum recession, enamel wear and any new problems. If sensitivity suddenly increases, becomes constant or is accompanied by pain on biting or swelling, contact the office, as this may indicate a problem that needs prompt treatment rather than a toothpaste change.
Planning your appointment
Describing your sensitivity
When booking at our Port Dover office from Silver Hill, mention which teeth are sensitive, what triggers it and how long it has been happening. This helps the dentist plan a focused examination.
Note whether you have recently whitened your teeth or changed toothpaste. Bring a list of products you use and any medications.

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 result from a new cavity, cracked tooth, recent whitening, gum recession or worn enamel. If sensitivity appears suddenly or is focused on one tooth, have it checked to rule out a problem that needs treatment.
Does sensitive toothpaste really work?
For many people, yes. Sensitivity toothpastes can reduce discomfort over a few weeks of consistent use. They work best for general sensitivity rather than problems like cavities or cracks, which need dental treatment.
Can brushing too hard cause sensitivity?
Yes. Aggressive brushing or using a hard-bristled brush can wear enamel and contribute to gum recession, exposing sensitive root surfaces. Switching to a soft brush and gentle technique can help protect your teeth.
Is sensitivity after a filling normal?
Some sensitivity after a new filling is common and usually fades within a few weeks. If it lingers, gets worse or occurs when biting, contact the office so the filling and tooth can be checked.
Can whitening make my teeth sensitive?
Yes, whitening often causes temporary sensitivity. It usually fades after treatment ends. Using sensitivity toothpaste before and during whitening may help. Tell the dentist if you already have sensitive teeth before whitening.
