Sensitivity is a symptom, and finding its cause guides the right relief.
Tooth sensitivity is a sharp, short twinge when teeth are exposed to cold, heat, sweets, acidic foods or even cold air. It often happens when the inner layer of the tooth, called dentin, becomes exposed through gum recession, enamel wear or a crack. Cavities, worn fillings and recent dental work can also trigger sensitivity, so the cause matters.
For people in Renton who wince when sipping a cold drink or breathing in winter air outdoors, an assessment at our Port Dover office can help identify what is behind it. The dentist will look for treatable problems and suggest products or treatments that may reduce discomfort over time.
Common causes
Several conditions can make teeth sensitive.
Exposed dentin
Gum recession exposes root surfaces, which lack protective enamel. Brushing too hard, gum disease and aging can contribute to recession. Enamel can also wear from grinding, acidic foods and drinks or acid reflux. Once dentin is exposed, tiny channels allow temperature changes to reach the nerve, causing those quick, sharp twinges you notice. It is common.
Dental problems
Cavities, cracked teeth, worn or leaking fillings and recently placed restorations can also cause sensitivity. Whitening treatments may cause temporary sensitivity. Sensitivity that lingers after the trigger is removed, or pain that throbs, may point to a more serious problem with the nerve and should be assessed promptly. Note how long each twinge lasts each time.
Assessment
A careful exam narrows down the source.
What the dentist checks
The dentist examines teeth for recession, wear, cracks, decay and failing restorations. Gentle tests with air or cold may help identify which teeth are affected. X-rays may be used to check for cavities or problems near the nerve. Gums are assessed for signs of disease that could be contributing to recession over time. Say if a test stings.
Information to share
Describe which teeth are sensitive, what triggers it, how long it lasts and when it started. Mention your brushing habits, toothpaste, diet, grinding and any reflux. Recent dental work or whitening is also relevant. These details help the dentist distinguish between surface sensitivity and deeper problems. Bring your toothpaste so its type can be checked.
Treatment options
Relief often combines home care and professional treatment.
At-home relief
Desensitizing toothpaste, used consistently for several weeks, can reduce sensitivity for many people. Brushing with a soft brush and gentle technique helps prevent further wear. Limiting acidic foods and drinks, using a straw for acidic beverages and waiting before brushing after acidic meals can protect enamel. Give home measures a few weeks before judging them.
In-office treatment
The dentist may apply fluoride varnish or desensitizing agents to sensitive areas. Bonding can cover exposed root surfaces. Fillings, crowns or onlays may repair damaged teeth. Gum grafting may be discussed for significant recession. If the nerve is involved, root canal treatment may be needed. The dentist will explain the options in turn. Ask freely.
Prevention
Good habits help prevent sensitivity from returning.
Protecting enamel
Use a soft toothbrush and gentle circular strokes rather than scrubbing. Choose a fluoride toothpaste, and keep using desensitizing toothpaste if it helps. Wear a night guard if you grind. Talk with your doctor if you have frequent heartburn or reflux, as stomach acid can erode enamel over time. Rinse with water after reflux episodes.
Ongoing care
Regular checkups allow the dentist to monitor recession, wear and restorations. Report new or worsening sensitivity promptly, as it may signal a developing problem. For Renton patients, mentioning sensitivity at routine visits can help catch issues early without needing separate trips. If sensitivity suddenly becomes severe or constant, though, call the office rather than waiting for a routine appointment.

Tooth sensitivity questions
Have a question about your situation? Our team can help you plan a visit.
Is tooth sensitivity serious?
Often it is caused by exposed dentin and is manageable. However, sensitivity can also signal cavities, cracks or nerve problems. Have it assessed, especially if it lingers, throbs or is getting worse over time. Call if unsure.
Does desensitizing toothpaste work?
Many people notice improvement after using it consistently for a few weeks. It works best as part of a broader approach. If sensitivity persists, the dentist can look for other causes and treatments that may help.
Can whitening cause sensitivity?
Yes, temporary sensitivity is a common side effect of whitening. It usually fades after treatment. Desensitizing toothpaste and adjusting the whitening routine can help. Let the dentist know if sensitivity is strong, since a pause or a gentler product may be advised.
Why are my teeth sensitive after a filling?
Some sensitivity after a filling is common and usually settles within a few weeks. If it worsens, lasts longer or the bite feels high, contact the office for a check. A small bite adjustment often helps.
Can I prevent sensitivity?
Gentle brushing with a soft brush, fluoride toothpaste, limiting acidic foods, wearing a night guard if you grind and regular checkups can help reduce the risk of sensitivity. Limiting frequent acidic drinks also helps protect enamel.
