Sensitive teeth have causes that can usually be addressed.
Tooth sensitivity is a sharp, brief pain triggered by cold, heat, sweets, acidic foods or even breathing in cold air. It often happens when the protective enamel wears thin or gums recede, exposing the softer layer underneath called dentin. Sensitivity can also signal a cavity, a cracked tooth or a leaking filling, so it is worth having checked properly.
If you live in Teeterville and have been avoiding cold drinks or certain foods, the dentist at our Port Dover office can look for the cause and suggest treatment. Many people find relief with simple changes to products and habits, while others need a specific repair to the tooth or gum.
Common causes
Finding the cause is the first step to relief.
Worn enamel and receding gums
Brushing too hard, using a hard-bristled brush, grinding, acidic foods and drinks and acid reflux can all wear enamel over time. Gum recession from aggressive brushing or gum disease exposes root surfaces, which lack enamel and are especially sensitive to temperature. Teeth whitening can also cause temporary sensitivity that usually fades once treatment ends completely.
Cavities, cracks and dental work
A cavity, cracked tooth, worn or leaking filling or recent dental work can trigger sensitivity in one particular spot. If the pain lingers long after the trigger is removed, or occurs without any trigger at all, the nerve may be involved and the tooth should be seen sooner. Note which teeth are affected and what sets off the pain.
Diagnosis
The dentist looks for the source of sensitivity.
Examining teeth and gums
The dentist examines your teeth for worn areas, cracks, cavities and receding gums. They check existing fillings and crowns for gaps at the edges. Your bite may be assessed for signs of grinding or clenching. Describing your brushing habits, diet, toothpaste and any recent dental treatments helps narrow down the cause more quickly and accurately.
Tests to pinpoint the cause
A gentle puff of air, a cold test or light tapping can help identify which tooth is sensitive and how the nerve responds. X-rays may be taken to look for decay between teeth or problems near the root. The dentist will explain what they find, how it relates to your symptoms and which treatments are most likely to help.
Treatment options
Treatment matches the cause.
Desensitizing products and treatments
Desensitizing toothpaste used consistently for several weeks can reduce sensitivity for many people. The dentist may apply fluoride varnish or a desensitizing agent to sensitive areas during a visit. Bonding resin can cover exposed root surfaces that are particularly troublesome. These treatments help block the tiny pathways that carry sensation through to the nerve inside.
Repairing the underlying problem
If a cavity, crack or failing filling is the cause, repairing it usually resolves the sensitivity. Gum grafting may be considered for significant recession, often with referral to a specialist. If the nerve is inflamed or damaged, root canal treatment may be recommended. The dentist will explain the options, their expected outcomes and the visits involved.
Prevention
Good habits help prevent sensitivity from returning.
Gentle brushing and the right products
Use a soft-bristled toothbrush and brush gently in small circles rather than scrubbing back and forth along the gum line. Choose a fluoride or desensitizing toothpaste and keep using it even after symptoms improve. Avoid brushing immediately after acidic foods or drinks, since enamel is temporarily softer. Ask the hygienist to check your technique at your next visit.
Protecting enamel
Limit acidic foods and drinks such as citrus, pop and sports drinks, and rinse with water afterward. If you grind your teeth, a night guard may help protect worn enamel. Treat acid reflux with your physician’s guidance. Regular checkups help catch early wear and gum recession before sensitivity becomes severe or constant in daily life.

Tooth sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Is tooth sensitivity a sign of a cavity?
It can be, but sensitivity also has many other causes, such as worn enamel, receding gums or a cracked filling. An exam helps the dentist identify the cause and recommend appropriate treatment, rather than guessing from symptoms alone.
How long does desensitizing toothpaste take to work?
Many people notice improvement within a few weeks of consistent use, twice a day. It works best when used regularly and not rinsed away straight after brushing. If sensitivity does not improve, see the dentist for further assessment.
Can whitening cause sensitivity?
Yes, whitening often causes temporary sensitivity, especially with stronger gels. It usually resolves after treatment ends. Using desensitizing toothpaste beforehand and following instructions carefully can help keep it manageable. Tell the dentist if it becomes uncomfortable.
Should I stop brushing sensitive teeth?
No. Keep brushing gently with a soft-bristled brush and a desensitizing toothpaste. Avoiding brushing can lead to plaque buildup, gum inflammation and more sensitivity, which only makes the problem worse over time for your teeth.
When is sensitivity a sign of something serious?
Pain that lingers, throbs, wakes you at night or comes with swelling may indicate nerve involvement or infection. Contact the office promptly if you experience these symptoms, rather than waiting for a routine appointment to come around.
