Le Dental Care – Your Trusted Dental Office in Danforth Neighbourhood.
Tooth sensitivity is a common dental concern that affects many people. If you experience discomfort or pain when consuming hot, cold, sweet, or acidic foods, or even when brushing, you may be dealing with sensitive teeth. At Le Dental Care – Dental Clinic Toronto, we help patients understand the causes of sensitivity and offer tailored solutions to restore comfort and confidence.
What Is Tooth Sensitivity?
Tooth sensitivity, also known as dentin hypersensitivity, occurs when the protective layers of the tooth—enamel or cementum—are worn down or damaged, exposing the underlying dentin. This allows external stimuli to reach the tooth’s nerve, causing pain or discomfort.
Common Causes of Tooth Sensitivity
Understanding the cause of your sensitivity is the first step toward effective treatment. Some common reasons include:
1. Worn Enamel
Overbrushing, using abrasive toothpaste, or consuming acidic foods can erode enamel, exposing the dentin beneath.
2. Gum Recession
Gum disease or aggressive brushing can cause the gums to pull away from the teeth, exposing the sensitive tooth roots.
3. Tooth Decay or Cracks
Cavities, cracked teeth, or damaged restorations can lead to exposed dentin or nerve irritation.
4. Teeth Grinding (Bruxism)
Grinding or clenching your teeth can wear down enamel and increase sensitivity.
5. Recent Dental Procedures
Sensitivity is common after dental treatments like fillings, cleanings, or crown placements. This is usually temporary.
6. Whitening Products
Overuse of bleaching products or whitening toothpaste can irritate the teeth and cause sensitivity.
How to Relieve Tooth Sensitivity
Depending on the cause and severity, various solutions can help:
Desensitising Toothpaste
These contain compounds like potassium nitrate or stannous fluoride that block nerve signals and reduce pain over time.
Fluoride Treatments
Professional fluoride application can strengthen enamel and protect sensitive areas.
Soft-Bristled Toothbrush
Switching to a soft brush and using gentle strokes prevents further enamel wear and gum recession.
Avoid Acidic or Trigger Foods
Minimize intake of citrus, vinegar, and sugary snacks that can aggravate sensitivity.
Mouth Guards
For patients who grind their teeth at night, custom night guards protect enamel and reduce pressure on the teeth.
Dental Restorations
In cases of decay, cracks, or significant wear, your dentist may recommend fillings, crowns, or bonding to cover and protect sensitive areas.
