Sensitive teeth are common, but they deserve a proper look.
Tooth sensitivity is a sharp, brief pain 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 dentin underneath, which contains tiny channels that lead to the nerve. Sensitivity can also signal a cavity, a cracked tooth or a leaking filling, so it is worth having it checked.
If you live in Windham Centre and twinges are making it harder to enjoy food and drink, our Port Dover office can help find out why. The dentist will examine your teeth and gums, identify the likely cause and recommend treatment, from special toothpaste to repairs, depending on what they find.
Common causes
Several different issues can cause the same twinge.
Worn enamel and receding gums
Brushing too hard, using a hard-bristled brush, grinding or eating acidic foods and drinks can wear enamel over time. Gum recession, often linked to gum disease or aggressive brushing, exposes root surfaces that lack enamel protection. Whitening can cause temporary sensitivity too. Recognising these causes helps you and the dentist decide what changes are most likely to bring relief.
Dental problems that cause sensitivity
Cavities, cracked teeth, chipped enamel and fillings or crowns with worn edges can all let stimuli reach the nerve more easily. In these cases, sensitivity may be concentrated in one tooth and may linger longer. The dentist will look for these problems, since treating the damaged tooth is usually needed to stop the sensitivity rather than simply masking it.
Assessment
Your description helps narrow down the cause.
Describing your symptoms
Note which teeth are sensitive, what triggers the pain and how long it lasts. Brief twinges that fade within seconds are typical of exposed dentin, while pain that lingers or throbs may suggest nerve involvement. Mention recent dental work, whitening, changes in your toothpaste or brushing habits, and whether you grind your teeth at night.
What the dentist checks
The dentist examines your teeth and gums, checks for cavities, cracks and worn fillings, and may take X-rays. They may gently apply air or cold to identify sensitive areas. Measuring gum recession and checking for grinding wear also helps. This information guides a treatment plan that targets the cause rather than offering only temporary relief.
Treatment options
Treatment ranges from simple changes to dental repair.
At-home strategies
Desensitising toothpaste, used consistently for several weeks, can reduce sensitivity by blocking the tiny channels in dentin. Switch to a soft-bristled brush and use gentle strokes. Limit acidic foods and drinks, and wait a while after consuming them before brushing. If you grind your teeth, a night guard may help protect enamel from further wear.
In-office treatments
The dentist may apply fluoride varnish or a bonding agent to sensitive areas to strengthen and seal them. Exposed roots may be covered with bonding material, and in some cases gum grafting is discussed. Cavities, cracks and leaking fillings are repaired. If the nerve is badly affected, root canal treatment may be recommended to relieve pain.
Preventing it returning
Good habits help keep sensitivity at bay.
Protective habits
Brush gently twice a day with a soft brush and fluoride or desensitising toothpaste. Floss daily to keep gums healthy and reduce recession. Rinse with water after acidic foods and drinks such as citrus, pop or wine. If you are whitening, follow instructions carefully and take breaks if sensitivity develops, rather than pushing through discomfort.
Regular monitoring
Regular checkups allow the dentist to monitor enamel wear, gum recession and existing fillings. Report any new or worsening sensitivity, especially if it affects one tooth or lingers after the trigger is gone. Addressing changes early can prevent more involved treatment later and keep you comfortable when eating and drinking from one day to the next.
Planning your appointment
Do not just live with sensitive teeth.
Call our Port Dover office to book an assessment. Windham Centre patients can describe which teeth are sensitive, what triggers the pain and how long it has been happening, so the dentist can plan the visit.
Bring the toothpaste and toothbrush you use, and mention any whitening products or recent dental work that might be relevant.

Tooth sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Does sensitive toothpaste really work?
Many people find desensitising toothpaste helpful when used consistently for several weeks. It works by blocking the channels in dentin. If sensitivity does not improve, or affects a single tooth, see the dentist to check for other causes.
Can sensitivity mean I have a cavity?
It can. Cavities, cracks and leaking fillings often cause sensitivity, especially in one tooth. The dentist can examine the area and take X-rays to determine whether a repair is needed, rather than relying on toothpaste alone.
Why are my teeth sensitive after whitening?
Whitening can temporarily increase sensitivity as the gel passes through enamel. It usually settles within a few days. Using desensitising toothpaste and following instructions carefully can help. Contact the office if sensitivity is severe or lasts longer than expected.
Is gum recession reversible?
Gum tissue does not grow back on its own, but further recession can often be slowed with gentle brushing and gum care. Exposed roots can be treated for sensitivity, and in some cases gum grafting may be discussed with a specialist.
When is sensitivity an emergency?
Sensitivity alone is rarely an emergency. However, lingering pain, throbbing, swelling or pain that wakes you at night may indicate nerve problems or infection. Call the office promptly if you notice any of these symptoms developing.
