As a dental hygienist who makes house calls, I often encounter patients troubled by tooth sensitivity—an issue that can make daily activities like eating and drinking a painful experience. Tooth sensitivity, also known as dentin hypersensitivity, is a common problem affecting millions of people worldwide. In this blog, we'll explore the causes of tooth sensitivity and discuss effective strategies for managing and preventing this discomfort.

Understanding Tooth Sensitivity:

Tooth sensitivity occurs when the protective enamel on our teeth wears down, exposing the underlying dentin and nerve endings. This exposure can lead to pain and discomfort, especially when encountering hot, cold, sweet, or acidic substances. Several factors contribute to tooth sensitivity:

1. Brushing Habits: Aggressive brushing or using a hard-bristled toothbrush can contribute to enamel erosion and gum recession, exposing the sensitive dentin.

2. Gum Recession: Receding gums expose the tooth roots, which lack the protective enamel covering and are more prone to sensitivity.

3. Dental Cavities: Cavities and tooth decay can lead to sensitivity, as they compromise the integrity of the tooth structure.

4. Bruxism (Teeth Grinding): Grinding or clenching the teeth can wear down enamel over time, contributing to sensitivity.

5. Acidic Foods and Beverages: Regular consumption of acidic foods and beverages can erode enamel and contribute to sensitivity.

Solving Tooth Sensitivity:

Now that we understand the common causes of tooth sensitivity, let's explore practical solutions to alleviate and prevent this discomfort. Often I like to start with all of the below and go from there...

1. Switch to a Soft-Bristled Toothbrush: Opt for a soft-bristled (or even ultra-soft) toothbrush to reduce the risk of enamel erosion during brushing. Gentle, circular motions are recommended for effective cleaning without causing damage. You may even want to stay away from an electric brush.

2. Use Desensitizing Toothpaste: Specialized desensitizing toothpaste can help alleviate tooth sensitivity. These toothpaste formulations typically contain ingredients like potassium nitrate, which block pain signals to the nerves.

3. Practice Good Oral Hygiene: Maintain a consistent oral hygiene routine, including regular brushing (with that soft toothbrush!), flossing, or a water flosser, and rinsing with fluoride mouthwash to prevent decay and gum disease.

4. Address Bruxism: If teeth grinding is a concern, consider using a custom-fitted night guard to protect your teeth from the effects of clenching and grinding. We would take alginate impressions of your teeth and then the lab makes a mouth guard for you.

5. Limit Acidic Foods and Beverages: Reduce the consumption of acidic foods and drinks, such as citrus fruits and sodas, to minimize enamel erosion. Or, at the very least, afterwards make sure to drink water and even 'swoosh' that water inside your mouth to get rid of the acids.

6. Get Your Teeth Checked Regularly: Schedule regular check-ups to identify and address any underlying dental issues contributing to sensitivity. Your dental hygienist may recommend treatments such as fluoride varnishes or dental bonding to strengthen tooth enamel.

   I like to see my clients every 6 months, and those with extreme sensitivity I apply a liquid 'desensitizer' that is only sold to dental professionals to combat the issue ASAP. It usually lasts 6 months to 12 months if you're lucky, and as long as I re-apply it, the client doesn't feel sensitivity anymore (or very little compared to before).

Tooth sensitivity is a common dental concern, but with the right care and preventive measures, you can enjoy a pain-free smile. By adopting gentle oral hygiene practices, using desensitizing toothpaste, and addressing contributing factors like bruxism, you can take significant steps towards managing and preventing tooth sensitivity.

Remember, consulting with your dental hygienist is crucial for personalized advice tailored to your unique dental needs. Embrace these strategies, and let your smile shine without the discomfort of sensitivity. Something as simple as switching your tooth brush, using a new toothpaste and getting a desensitizer applied by your dental hygienist at your cleaning appointments can solve the issue!

Feel free to let me know if any questions :). I'm very happy to schedule a virtual consultation with anyone, you do not have to live in Winnipeg for a virtual consult.
