Sensitive teeth are common, and the cause determines the fix.
Tooth sensitivity often feels like a quick, sharp pain when teeth meet cold drinks, hot food, sweets, acidic foods or even cold air. It usually happens when the protective enamel wears down or gums recede, exposing the dentin underneath, which contains tiny channels leading to the nerve. Sensitivity can also signal decay, a cracked tooth or a failing filling.
Langton patients bothered by sensitive teeth can have them assessed at our Port Dover office. The dentist will look for the underlying cause, rule out problems that need treatment and suggest ways to reduce sensitivity, from simple changes in toothpaste and brushing habits to in-office treatments or restorations where appropriate.
Causes
Several factors can expose the sensitive layer of a tooth.
Worn enamel and receding gums
Brushing too hard or with a hard-bristled brush, grinding, and frequent exposure to acidic foods and drinks can wear away enamel over time. Gum recession, caused by gum disease, ageing or aggressive brushing, exposes root surfaces that have no enamel protection. These exposed areas are often the source of sensitivity to cold, touch and sweet foods.
Other dental problems
Cavities, cracked teeth, worn or leaking fillings and recent dental work can also cause sensitivity. Whitening treatments may cause temporary sensitivity. Sensitivity that lingers after the trigger is removed, or throbbing pain, may indicate an irritated nerve. The dentist will examine your teeth to determine whether the cause is surface exposure or something deeper inside the tooth.
Assessment
Identifying the cause guides effective treatment.
Describing the sensitivity
Note which teeth are sensitive, what triggers the discomfort and how long it lasts. Mention whether it started after a dental procedure, a change in toothpaste or a new habit. Sensitivity that comes and goes quickly is often due to exposed dentin, while pain that lingers or worsens over time may point to a problem with the nerve.
The examination
The dentist examines your teeth and gums, looking for recession, worn enamel, cavities, cracks and failing restorations. They may test teeth with air or cold and take X-rays to check for hidden decay or other issues. Your brushing habits, diet and any signs of grinding will also be considered when planning treatment that fits your routine.
Treatment options
Relief often starts with simple changes.
At-home care
Desensitizing toothpaste, used consistently for several weeks, can block the tiny channels in dentin and reduce sensitivity. Brush gently with a soft-bristled brush and avoid scrubbing. Limit acidic foods and drinks such as citrus, soda and wine, and avoid brushing right after consuming them. Using a straw for acidic drinks can help protect the teeth too.
In-office treatments
The dentist may apply fluoride varnish or a desensitizing agent to sensitive areas. Bonding resin can cover exposed root surfaces. If sensitivity is caused by decay, a cracked tooth or a failing filling, treating that problem directly is necessary. In cases of significant gum recession, referral for gum grafting may be discussed with you as an option.
Prevention
Small habits help prevent sensitivity from returning.
Daily habits
Use a soft toothbrush with gentle, circular motions, and replace it every few months. Choose a fluoride or desensitizing toothpaste. Wait a while after acidic meals before brushing to protect softened enamel. If you grind or clench, ask the dentist whether a night guard could help protect enamel from further wear and reduce sensitivity over time.
Regular dental visits
Regular checkups and cleanings allow the dentist to catch gum recession, decay and worn fillings before they cause significant sensitivity. Report new or worsening sensitivity, especially if it lingers or comes with pain when biting, as this may indicate a problem that needs treatment. Early attention helps keep teeth comfortable and healthy for the long term.

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 a new cavity, cracked tooth, gum recession, recent dental work or whitening. It may also follow changes in brushing habits or diet. Have it checked by the dentist to identify the cause.
Does desensitizing toothpaste really work?
For many people, yes. Desensitizing toothpaste works gradually by blocking pathways to the nerve or calming nerve signals. It usually takes a few weeks of consistent use to notice a difference. Continue using it to maintain the effect.
Can sensitivity be a sign of something serious?
Sometimes. Sensitivity that lingers, worsens or is accompanied by pain when biting may indicate decay, a cracked tooth or nerve inflammation. These problems need professional assessment and treatment rather than simply masking symptoms with toothpaste.
Is tooth sensitivity after whitening normal?
Yes, temporary sensitivity is common during or after whitening and usually fades within a few days. Using desensitizing toothpaste and following the dentist’s instructions can help. Tell the dentist if it persists or becomes severe.
Can brushing too hard cause sensitivity?
Yes. Brushing aggressively or with a hard-bristled brush can wear down enamel and cause gums to recede, exposing sensitive root surfaces. Use a soft brush and gentle technique, and ask the hygienist to check your brushing method.
