Sensitive teeth usually have a cause that can be identified.
Tooth sensitivity is a sharp, short pain triggered by cold, heat, sweet foods or even breathing in cold air. It often happens when the protective enamel wears thin or gums recede, exposing dentin underneath. Cracks, decay and recent dental work can also cause sensitivity, so finding the source matters.
If you are in Cultus and sensitive teeth are making meals uncomfortable, our Port Dover dentists can help find out why. We will examine your teeth and gums, ask about your habits and recommend treatments that target the cause rather than only masking the discomfort.
Common causes
Several problems can expose sensitive layers.
Enamel wear and gum recession
Brushing too hard, acidic foods and drinks, grinding and reflux can wear enamel. Gum recession exposes root surfaces that lack enamel protection. These exposed areas contain tiny channels leading to the nerve, which is why temperature changes cause discomfort. Whitening toothpastes and very abrasive powders can also wear surfaces over time, and acid from frequent snacking softens enamel so brushing removes a little more of it.
Cracks, decay and dental work
A cracked tooth, a new cavity or a leaking filling can cause sensitivity in one specific spot. Teeth may also be sensitive after whitening, cleanings or new fillings, usually temporarily. Telling the dentist when sensitivity started helps identify the cause. If it began right after a new filling or crown, the bite may simply need a small adjustment, which is quick to do.
Assessment
Details help pinpoint the problem.
Describing your symptoms
Note which teeth are sensitive, what triggers the pain and how long it lasts. Sensitivity that fades quickly after the trigger is removed often relates to exposed dentin. Pain that lingers or throbs may suggest nerve inflammation and needs prompt assessment. Pain on biting is another detail worth sharing, since it can point to a crack rather than worn enamel.
Examination and tests
The dentist examines your teeth and gums, looks for wear, recession, cracks and decay and may use cold or air to test specific teeth. X-rays help check for hidden problems. The dentist will explain what they find and the likely cause. Sometimes more than one factor is involved, such as recession combined with brushing habits, and each may need its own small adjustment.
Treatment
Treatment depends on the cause.
Desensitizing products
Desensitizing toothpaste, used consistently, can gradually reduce sensitivity by blocking channels in dentin. In-office fluoride varnish or desensitizing agents may provide additional relief. The dentist may recommend a specific product and explain how long it typically takes to work. Smearing a little on the sensitive spot before bed and not rinsing afterward can help some people, and switching products too often makes it hard to judge what helps.
Treating the underlying cause
If sensitivity is caused by decay, a crack or a failing filling, the tooth may need repair. Bonding can cover exposed root surfaces. Gum grafting may be suggested for significant recession. A night guard can help if grinding is contributing. Root canal treatment is considered if the nerve is affected. That is a last resort.
Prevention
Simple changes can protect your teeth.
Gentle brushing habits
Use a soft-bristled toothbrush and brush gently, using small circular motions rather than hard scrubbing. Avoid abrasive whitening toothpastes if your teeth are sensitive. Ask the hygienist to check your technique and recommend a toothpaste suited to sensitivity. An electric toothbrush with a pressure sensor can be helpful for people who tend to scrub hard without realizing it, and replacing worn brushes regularly keeps bristles gentle.
Diet and lifestyle
Limit acidic foods and drinks, such as citrus, soda and sports drinks, and drink water afterward. Wait before brushing after acidic foods to let enamel recover. If you have reflux, talk with your physician. Regular checkups help catch problems early. Grinding at night is another common contributor, so mention it if you wake with a tired jaw, as a night guard may protect worn surfaces from further damage.

Sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Why are my teeth suddenly sensitive?
Sudden sensitivity may be caused by a crack, new cavity, recent dental work or gum recession. Have it assessed, especially if it affects one tooth or lingers. Early checks keep options simple and treatment quick.
Does sensitivity toothpaste really work?
For many people, yes, when used consistently for several weeks. It works best for sensitivity caused by exposed dentin. Other causes may need different treatment, so check with the dentist if it does not help.
Can whitening make teeth sensitive?
Yes, whitening often causes temporary sensitivity. It usually fades after treatment ends. Using sensitivity toothpaste or adjusting the whitening schedule can help. Taking a few days off between sessions often makes a noticeable difference to comfort.
Is tooth sensitivity a sign of a serious problem?
Often it is caused by minor wear or recession, but it can signal decay, a crack or nerve problems. Have persistent or lingering sensitivity checked, especially if it is getting worse or spreading to other teeth.
Can grinding cause sensitivity?
Yes. Grinding wears enamel and can cause cracks, both of which may lead to sensitivity. A night guard may help protect your teeth from further wear while sensitivity settles. Mention any morning jaw tiredness too.
