How to Reduce Tooth Sensitivity: Dentist-Approved Tips
Tooth sensitivity occurs when the protective enamel on your teeth wears down or gums recede, exposing the underlying dentine and its tiny nerve-connected tubules. The result is sharp, short-lived pain triggered by hot, cold, sweet, or acidic foods and drinks. The good news is that there are several practical, dentist-approved steps you can take to reduce sensitivity and protect your teeth.
Why Do Teeth Become Sensitive?
Understanding the cause of your sensitivity is the first step toward relief. Common triggers include:
- Enamel erosion from acidic foods, drinks, or aggressive brushing
- Gum recession that exposes the root surface
- Tooth grinding (bruxism) that wears down enamel over time
- Cracked or chipped teeth that expose inner dentine
- Recent dental procedures such as whitening or fillings, which can cause temporary sensitivity
- Tooth decay or gum disease that damages protective tooth structure
If your sensitivity is sudden, severe, or worsening, it is important to see a licensed dentist promptly, as it may signal an underlying issue requiring professional care.
Practical Tips to Reduce Tooth Sensitivity
1. Use a Toothpaste Formulated for Sensitive Teeth
Desensitising toothpastes are one of the most accessible first steps. Look for products containing potassium nitrate or stannous fluoride, which work by blocking the microscopic dentinal tubules that transmit pain signals to the nerve. Use the toothpaste consistently — results typically improve over two to four weeks. Your dentist may also apply in-office fluoride varnish or desensitising agents for faster relief.
2. Improve Your Brushing Technique
Brushing too hard or using a hard-bristled toothbrush is a leading cause of enamel wear and gum recession — both of which contribute to sensitivity. Follow these guidelines:
- Use a soft-bristled toothbrush
- Brush for a full two minutes, twice daily
- Use gentle, circular motions rather than scrubbing back and forth
- Hold the brush at a 45-degree angle to the gumline
- Consider an electric toothbrush with a pressure sensor to prevent over-brushing
3. Limit Acidic Foods and Drinks
Acidic foods and beverages — including wine, soda, citrus fruits, pastries, and chocolate — erode tooth enamel over time, worsening sensitivity. Practical strategies include:
- Rinsing your mouth with water immediately after consuming acidic items
- Waiting at least 30 minutes before brushing after eating or drinking acidic foods, as enamel is temporarily softened
- Drinking acidic beverages through a straw to reduce direct contact with teeth
- Balancing your diet with enamel-strengthening foods rich in calcium and phosphorus
4. Address Teeth Grinding (Bruxism)
Many people grind or clench their teeth during sleep without realising it. Bruxism gradually wears down enamel and is a significant contributor to sensitivity. A licensed dentist can fit you with a custom night guard to protect your teeth while you sleep. If you suspect grinding is affecting your teeth, ask about TMJ Treatment at Expressions Dental Calgary NW, which addresses jaw-related issues linked to grinding.
5. Maintain a Consistent Oral Hygiene Routine
Healthy gums and clean teeth are your best defence against sensitivity. Gum disease and plaque build-up can expose root surfaces and worsen pain. Scheduling regular professional cleanings is essential — our teeth cleaning service in Calgary removes built-up tartar and plaque that at-home brushing cannot reach, helping to prevent gum recession and sensitivity over time. You may also benefit from Guided Biofilm Therapy (GBT), an advanced, gentle cleaning technique ideal for patients with sensitive teeth.
6. Consider Professional Dental Treatments
When sensitivity is persistent or severe, over-the-counter solutions may not be enough. A licensed dentist can recommend targeted treatments such as:
- Fluoride varnish applied directly to sensitive areas
- Dental bonding or sealants to cover exposed root surfaces
- Gum grafting for significant gum recession
- Composite white fillings to restore areas damaged by decay or erosion
- Root canal treatment in cases where sensitivity is caused by infection or significant nerve involvement
7. Be Cautious with Teeth Whitening
Teeth whitening treatments can temporarily increase sensitivity, particularly for those who already have sensitive teeth. If you are considering whitening, speak with a licensed dentist before beginning. At Expressions Dental, we can recommend the most appropriate option for your situation and help you manage any sensitivity during the process.

When Should You See a Dentist About Tooth Sensitivity?
While mild sensitivity is common and manageable at home, you should book an appointment if:
- Pain is severe, persistent, or spontaneous (not just triggered by temperature)
- Sensitivity is confined to one specific tooth
- You notice visible cracks, chips, or dark spots on your teeth
- Sensitivity has developed suddenly or worsened quickly
- Home treatments have not provided relief after several weeks
In any of these cases, prompt assessment by a licensed dentist is important to rule out decay, fractures, or other underlying conditions.

Frequently Asked Questions
What causes tooth sensitivity?
Tooth sensitivity is most commonly caused by enamel erosion, gum recession, teeth grinding, cracked teeth, or decay — all of which can expose the dentine and its nerve-connected tubules. Triggers such as hot, cold, sweet, or acidic foods and drinks then stimulate these nerves, causing sharp, temporary pain. A licensed dentist can identify the underlying cause and recommend the right treatment.
Can sensitive teeth be cured permanently?
Whether sensitivity can be fully resolved depends on its underlying cause. In many cases, consistent use of desensitising toothpaste, improved brushing habits, and professional treatments such as fluoride varnish or bonding can significantly reduce or eliminate sensitivity. For more serious causes like deep decay or gum disease, professional dental treatment is needed for lasting relief.
Is toothpaste for sensitive teeth actually effective?
Yes, desensitising toothpastes containing potassium nitrate or stannous fluoride are clinically proven to reduce tooth sensitivity over time. They work by blocking the tiny dentinal tubules that transmit pain signals to the nerve. Results are typically noticeable after two to four weeks of consistent use, and your dentist may also apply in-office treatments for faster results.
How long does tooth sensitivity last after whitening?
Post-whitening sensitivity is common and usually temporary, typically resolving within a few days to a week after treatment. Using a desensitising toothpaste before and after whitening can help minimise discomfort. If you have pre-existing sensitivity, speak with a licensed dentist before beginning any whitening treatment to find the safest option for your teeth.
Can brushing too hard cause sensitive teeth?
Yes, brushing too aggressively or using a hard-bristled toothbrush is one of the most common causes of enamel wear and gum recession, both of which lead to increased tooth sensitivity. Switching to a soft-bristled toothbrush and using gentle, circular motions can prevent further damage. An electric toothbrush with a built-in pressure sensor is a helpful tool for those who tend to over-brush.
Are sensitive teeth a sign of something serious?
Mild sensitivity to temperature or sweets is common and often manageable at home. However, sensitivity that is severe, persistent, spontaneous, or localised to one tooth may indicate a more serious issue such as a cracked tooth, deep decay, or infection. In these cases, it is important to see a licensed dentist promptly for a proper assessment.
How can a dentist in Calgary NW help with tooth sensitivity?
A licensed dentist at a clinic like Expressions Dental in Calgary NW can identify the specific cause of your sensitivity through a thorough examination and, if needed, digital X-rays. Treatment options may include professional fluoride application, dental bonding, a custom night guard for grinding, fillings, or, in more advanced cases, root canal treatment. Regular professional cleanings also play an important role in preventing the gum recession and decay that contribute to sensitivity.
