Caring for Nanticoke patients at our Port Dover office
Browse every service for Nanticoke patientsThat sharp twinge
Sensitive teeth usually have a cause that can be found.
Tooth sensitivity is a short, sharp pain triggered by cold, hot, sweet or acidic foods, cold air or brushing. It often happens when the inner layer of the tooth, called dentin, becomes exposed through gum recession, worn enamel or a crack. It can also be a sign of decay or a failing filling, so persistent sensitivity is worth having checked.
If you live in Nanticoke and certain foods or drinks make your teeth wince, the dentist at our Port Dover office can find the source of the sensitivity and suggest treatments to help reduce it and protect your teeth.
Causes
Several conditions can make teeth sensitive.
Exposed dentin
Gum recession exposes root surfaces, which lack protective enamel. Enamel can wear from aggressive brushing, grinding or acidic foods and drinks. When dentin is exposed, tiny channels allow temperature and other stimuli to reach the nerve, causing a sharp but brief pain. That is why the twinge usually fades within seconds once the cold drink or sweet food is gone, instead of lingering.
Other dental problems
Cavities, cracked teeth, worn or leaking fillings and recent dental work can also cause sensitivity. Whitening treatments may cause temporary sensitivity. Pain that lingers after the trigger is removed may suggest nerve inflammation and should be assessed promptly. A brief twinge and a lingering ache often point to quite different causes and quite different treatments.
Assessment
Details help the dentist pinpoint the cause.
Describing your sensitivity
Note which teeth are sensitive, what triggers the pain and how long it lasts. Mention brushing habits, grinding, acidic foods or drinks and recent whitening or dental work. These details help the dentist understand whether the sensitivity is from exposed dentin or something more serious. A quick note on your phone over a week or two often captures the pattern better than memory.
Examination
The dentist examines the teeth and gums, may test teeth with air or cold and takes X-rays if needed. They look for recession, wear, cracks, decay and problems with existing fillings. Identifying the cause allows the dentist to recommend appropriate treatment. Sometimes more than one factor is involved, such as recession alongside an older filling that has started to leak.
Treatment
Treatment depends on what is causing the sensitivity.
Desensitizing measures
Desensitizing toothpaste, used consistently, can help block the channels in exposed dentin. Fluoride varnish or other desensitizing agents may be applied in the office. Bonding a thin layer of resin over exposed root surfaces may help in some cases. The dentist will recommend options suited to your situation. A desensitizing toothpaste can take a few weeks of daily use before its full benefit is noticeable.
Treating the underlying cause
If decay, cracks or failing fillings are causing sensitivity, they need to be treated. Gum grafts may be considered for significant recession. A night guard may help if grinding is wearing enamel. Root canal treatment may be recommended if the nerve is inflamed and sensitivity is severe or lingering. Ask the dentist why a particular option is suggested and what recovery looks like.
Prevention
Small changes can help prevent sensitivity.
Brushing and diet
Use a soft-bristled toothbrush and gentle technique, brushing in small circles rather than scrubbing. Limit acidic foods and drinks, and avoid brushing immediately after consuming them. Rinse with water instead. Use a desensitizing toothpaste as recommended, and at night try spitting out the excess rather than rinsing, so the active ingredients stay on the teeth longer.
Ongoing care
Regular checkups help catch problems that cause sensitivity early. If you grind your teeth, wear a night guard as recommended. Report new or worsening sensitivity, especially pain that lingers, so the dentist can assess whether further treatment is needed. Catching changes early usually means simpler, more comfortable care for the tooth involved.

Tooth 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 gum recession, enamel wear, a new cavity, a cracked tooth or recent dental work. Have it checked so the dentist can identify the cause and recommend treatment.
Does desensitizing toothpaste work?
Many people find relief with consistent use over several weeks. It works by blocking channels in exposed dentin. If sensitivity persists despite using it, the dentist can look for other causes and suggest additional options, such as an in-office varnish.
Can brushing too hard cause sensitivity?
Yes. Aggressive brushing can wear enamel and contribute to gum recession, exposing dentin. Using a soft brush and gentle technique helps protect teeth. The hygienist can review your brushing technique and suggest a suitable brush and pressure.
Is sensitivity a sign of a cavity?
It can be. Cavities, cracked teeth and failing fillings can cause sensitivity. The dentist will examine your teeth to determine whether decay or another problem is the cause, and X-rays may be suggested to check between teeth.
When should I worry about sensitivity?
Sensitivity that lingers after the trigger, wakes you at night or is accompanied by swelling should be assessed promptly. These may suggest nerve inflammation or infection that needs treatment.
