Ouch! Why Are My Teeth So Sensitive? Understanding Causes & Relief Options
Does a sip of cold water or a bite of something sweet send a sharp pain through your teeth? You’re not alone. Tooth sensitivity is one of the most common concerns patients mention during routine visits at Tooth Harmony in Niagara Falls.
While occasional discomfort might seem normal, persistent sensitivity often signals an underlying issue—and there are effective ways to treat it.
In this blog, we’ll explore what causes tooth sensitivity, when to seek help, and how we can support you with gentle, personalized care.
What Is Tooth Sensitivity?
Tooth sensitivity—also known as dentin hypersensitivity—occurs when the protective layer of your teeth (enamel or cementum) becomes worn or compromised, exposing the softer inner layer of the tooth called dentin. This layer contains tiny tubules that connect directly to the nerve, which is why certain triggers cause sharp, temporary pain.
Common Triggers for Sensitive Teeth
Cold foods or drinks (like ice cream or cold water)
Hot beverages (like coffee or tea)
Sweet or acidic foods (such as citrus, soda, or candy)
Brushing or flossing (especially around the gumline)
Breathing in cold air
These sensations can range from mild discomfort to intense, short bursts of pain.
What Causes Tooth Sensitivity?
There are several reasons you may be experiencing this discomfort. The most common include:
1. Worn Tooth Enamel
Brushing too hard, using a hard-bristled toothbrush, or using abrasive toothpaste can wear down enamel over time.
2. Gum Recession
As gums pull back, they expose the root surfaces of teeth, which are not protected by enamel.
3. Tooth Grinding (Bruxism)
Clenching or grinding your teeth can wear down enamel and cause micro-fractures, leading to sensitivity.
4. Acidic Diet
Frequent consumption of acidic drinks or foods can erode enamel and make teeth more vulnerable.
5. Cracked or Damaged Teeth
Even tiny cracks can expose the inner tooth layers and lead to sensitivity.
6. Post-Treatment Sensitivity
Sometimes, dental procedures like cleanings, fillings, or whitening may cause temporary sensitivity—which usually resolves within a few days.
How We Help at Tooth Harmony
At Tooth Harmony in Niagara Falls, we don’t just treat the symptom—we identify and address the cause. Here’s how we help patients manage and reduce sensitivity:
Thorough Examination: We check for enamel wear, cracks, gum recession, or signs of grinding.
Desensitizing Treatments: We may apply fluoride varnishes or desensitizing agents to reduce nerve response.
Custom Mouthguards: If grinding is a problem, we can fit you with a nightguard to protect your teeth while you sleep.
Dental Restorations: For exposed roots or cracked enamel, we may recommend a bonded filling or sealant to shield the area.
Hygiene Tips & Product Recommendations: We’ll guide you on gentle brushing techniques and suggest non-abrasive toothpaste designed for sensitive teeth.
At-Home Tips to Reduce Sensitivity
Use a soft-bristled toothbrush and brush gently
Switch to toothpaste for sensitive teeth (and give it a couple weeks to take effect)
Avoid acidic foods and drinks—or rinse with water afterwards
Don’t brush immediately after acidic meals—wait at least 30 minutes
Floss daily to prevent gum issues and keep roots covered
Stay hydrated to support healthy saliva production
