Sensitive teeth are common, and the cause can usually be found.
Tooth sensitivity is a sharp, short pain triggered by cold, heat, sweet or acidic foods, or even breathing in cold winter air. It often happens when the protective enamel wears down or gums recede, exposing the softer dentin underneath, which has tiny channels leading toward the nerve. Cracks, cavities and recent dental work can also cause sensitivity.
Walsh residents bothered by sensitive teeth can have them checked at our Port Dover office. The dentist will look for the underlying cause, rule out problems such as decay or cracks and recommend treatments and habits to reduce sensitivity and protect your teeth over the long term.
Causes
Several factors can expose sensitive areas.
Worn enamel and receding gums
Brushing too hard, using a hard-bristled toothbrush, grinding, frequent acidic foods and drinks, and gum disease can all wear away enamel or cause gums to recede over time. Exposed root surfaces have no enamel covering at all and are especially sensitive to cold. Whitening treatments can also cause a temporary bout of sensitivity that usually fades.
Other dental problems
Cavities, cracked teeth, worn or leaking fillings and recent dental procedures can trigger sensitivity that feels very similar to the more harmless kind. Sensitivity that lingers for a long time after the trigger, or that gets steadily worse, may signal a deeper problem with the nerve. The dentist will check for these before recommending any treatment.
Assessment
Details help the dentist narrow it down.
Describing your symptoms
Note which teeth are sensitive, what triggers the pain and how long it lasts once it starts. Brief sensitivity that disappears within seconds is often related to exposed dentin. Pain that lingers for minutes, throbs or wakes you at night may point to inflammation of the nerve and needs closer attention, so describe it as accurately as you can.
The examination
The dentist examines the teeth and gums, checks for recession, decay, cracks and worn fillings, and may use a puff of air or cold to identify exactly which spots are sensitive. X-rays may be taken to rule out deeper problems such as decay under a filling. The findings are explained before any treatment is suggested, so you understand the cause.
Treatment
Treatment depends on the cause.
Desensitizing products and fluoride
Desensitizing toothpaste, used consistently twice a day over a few weeks, can help block the tiny channels in dentin and calm the response. Fluoride varnish applied in the office, or a prescription-strength fluoride toothpaste, may strengthen enamel further. The dentist may recommend specific products and explain how to use them for the best result at home.
Dental treatments
Bonding or sealants can cover exposed root surfaces that are particularly sensitive. A gum graft may be considered for significant recession, usually with a specialist. Cavities or cracks are repaired with fillings or crowns. If the nerve is irreversibly inflamed, root canal treatment may be discussed as the way to resolve the pain for good.
Prevention
Small changes can reduce sensitivity.
Brushing and diet habits
Use a soft-bristled toothbrush with gentle pressure, and avoid scrubbing hard from side to side along the gumline. Limit acidic foods and drinks such as citrus, pop and sports drinks, and wait a while after having them before you brush, since enamel is softer straight afterwards. Rinsing with water after acidic foods helps neutralize the acid.
Guarding against grinding
If you grind or clench, a night guard may help protect your enamel from further wear. Keep regular checkups, so the dentist can monitor gum recession and enamel wear over time. Contact the office if your sensitivity changes, spreads or becomes painful, rather than waiting for your next scheduled visit from Walsh to mention it.

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 come from a new cavity, a cracked tooth, gum recession, whitening or recent dental work. An exam helps identify the cause, so the right treatment can be recommended instead of guessing at a solution.
Does sensitivity toothpaste really work?
For many people, yes, when it is used consistently for a few weeks. It helps block the channels in dentin. If sensitivity persists despite using it, see the dentist to rule out other underlying causes such as decay or cracks.
Can sensitivity be a sign of a cavity?
Yes. Sensitivity to sweets or cold can indicate decay. Lingering pain may suggest the nerve is affected. The dentist will check for cavities and other problems during your exam and explain what was found and why.
Will sensitivity go away on its own?
Sometimes, especially after whitening or recent dental work. Ongoing sensitivity usually has a cause that should be addressed. Changing brushing habits and using desensitizing products may also help it settle over time, but persistent cases deserve a proper look.
Can grinding cause sensitivity?
Yes. Grinding can wear enamel and cause tiny cracks, exposing the dentin underneath. A night guard may help protect teeth from further wear. The dentist can assess the wear pattern and advise on suitable protection.
