Managing Tooth Sensitivity: A Guide for Adults in London, Ontario

If you’ve ever winced while sipping a hot coffee or biting into ice cream, you’re not alone. Tooth sensitivity is a common dental concern among adults in London, Ontario, and it can turn everyday pleasures into painful experiences. But what causes this discomfort and more importantly, how can you manage it?

Why Your Teeth React to Hot, Cold, Sweet, or Acidic Foods

Tooth sensitivity, also known as dentine hypersensitivity, occurs when the protective layers of your teeth are compromised, exposing the underlying dentine. Dentine contains microscopic tubules that lead to the tooth’s nerve centre. When exposed to hot, cold, sweet, or acidic stimuli, these tubules transmit sensations directly to the nerve, causing sudden sharp pain.

Common Causes of Tooth Sensitivity

Several factors can contribute to sensitive teeth:

• Worn Tooth Enamel

Brushing too aggressively or using a hard-bristled toothbrush can wear down enamel over time. Enamel erosion also occurs due to acidic foods and drinks, such as citrus fruits, soda, and wine.

• Gum Recession

Gums naturally recede with age or due to gum disease, exposing the tooth roots which lack enamel protection. This makes them more vulnerable to sensitivity.

• Tooth Decay or Cracked Teeth

Cavities and cracks can expose the dentine or even the pulp of the tooth, leading to heightened sensitivity and potential infection.

• Dental Procedures

Recent fillings, crowns, or cleaning can temporarily increase sensitivity. If it persists, it may indicate an underlying issue. Learn more about this in our blog: The Link Between Dental Fillings and Tooth Sensitivity: Causes and Solutions.

• Grinding Your Teeth

Bruxism (teeth grinding) wears down enamel and can lead to sensitivity. Teeth grinding often occurs without a person’s awareness, particularly during sleep.

• Whitening Products

Some over-the-counter whitening toothpastes and treatments contain harsh chemicals that can irritate the teeth and gums.

How to Manage Tooth Sensitivity Effectively

Fortunately, there are several strategies to reduce and manage tooth sensitivity:

1. Switch to a desensitizing toothpaste

These toothpastes contain compounds like potassium nitrate or stannous fluoride that block pain signals from the tooth surface to the nerve. It may take a few weeks of consistent use to notice results.

2. Use a soft-bristled toothbrush

Gentle brushing helps preserve enamel and prevent gum recession. Combine this with proper technique—avoid scrubbing and use circular motions.

3. Avoid acidic foods and drinks

Limit your intake of citrus, soda, and wine. If you do consume them, rinse your mouth with water afterward and wait at least 30 minutes before brushing.

4. Treat underlying dental issues

If sensitivity is caused by decay, cracks, or gum disease, professional treatment is essential. Your dentist may recommend fillings, fluoride treatments, or even root canal therapy depending on the severity.

5. Consider a mouthguard

If you grind your teeth, a custom night guard can protect your enamel and reduce sensitivity.

6. Floss gently and regularly

Flossing helps prevent gum disease, which can lead to recession and sensitivity. If your gums are sensitive, check out our guide: The Best Flossing Techniques for Sensitive Gums.
