What Causes Tooth Sensitivity? Common Triggers and How Tooth Harmony Can Help
Ever felt a sudden zing when eating ice cream or sipping hot coffee? Tooth sensitivity is one of the most common concerns we see at Tooth Harmony in Niagara Falls. While it’s often manageable, persistent sensitivity can signal that your teeth or gums need extra care.
Here’s what causes sensitive teeth, how to manage it at home, and when it’s time to book a dental visit.
Common Causes of Sensitive Teeth
Tooth sensitivity often feels like a quick, sharp discomfort when your teeth are exposed to:
Hot or cold food and drinks
Sweet or acidic items
Brushing or flossing
Cold air while breathing or talking
For some people, it’s occasional. For others, sensitivity can be ongoing and interfere with daily comfort.
Common Causes
Some of the most frequent causes we diagnose at our Niagara Falls dental clinic include:
Enamel Erosion
Enamel protects the inner dentin of your teeth. Acidic foods, teeth grinding, or aggressive brushing can wear it down over time.Receding Gums
Gums may recede due to brushing too hard, gum disease, or natural aging—exposing unprotected parts of the tooth.Tooth Decay or Worn Fillings
Cavities or old dental work can create weak spots that trigger discomfort.Cracked or Chipped Teeth
Even small fractures can expose nerves and cause sensitivity when chewing.Post-Dental Treatment Sensitivity
Some procedures, like fillings, crowns, or whitening, may cause temporary sensitivity that usually improves with time.
At-Home Tips to Reduce Sensitivity
For mild symptoms, these adjustments may help:
Switch to a sensitivity toothpaste to block pain signals
Use a soft-bristled toothbrush and gentle strokes
Limit acidic foods and drinks
Floss daily to keep gums healthy
Wear a night guard if you grind your teeth
At your check-up, our team at Tooth Harmony can recommend products tailored to your needs.
When to See a Dentist About Sensitivity
