The Signs and Symptoms of Tooth Sensitivity
Tooth sensitivity happens when the nerves inside your teeth become irritated. Normally, your teeth are protected by a hard outer layer called enamel. Beneath that is dentin, and at the core is the pulp, which contains connective tissue, blood vessels, and nerves. When enamel wears thin or gets damaged, exposing the dentin, your tooth’s nerve is vulnerable to irritation.
How Does Tooth Enamel Get Damaged?
Several everyday habits and conditions can wear down enamel, including:
- Consuming acidic foods and drinks, especially before bedtime
- Skipping regular dental care, like flossing
- Brushing too hard or using a stiff toothbrush
- Trying to use professional dental tools at home
- Health issues such as acid reflux or bulimia, exposing teeth to stomach acid
- Untreated gum disease and gum recession
- Cracked, chipped, or damaged teeth
- Cavities left untreated
- Using tobacco, cannabis, or vaping products
- Grinding or clenching teeth
- Overusing teeth whitening products
What Can You Do About Sensitive Teeth?
The most important first step is to visit a Dentist in Mississauga to identify the root cause of your sensitivity. Your dentist will rule out other potential problems and recommend appropriate treatment. Here’s what you can expect:
Find the Underlying Cause
During your examination, your dentist will ask you to describe your sensitivity, when it happens and how severe it is. You may need new X-rays and other tests, like a tap or cold test, to help pinpoint the issue.
In-Office Treatment
If your teeth are damaged or decayed, restorative treatments such as fillings or crowns can help. For worn enamel, home care might be enough, but there are also effective in-office treatments to consider. Your dentist will explain all options so you can decide the best plan for you.
Personalized Advice
Because tooth sensitivity can come from many causes, your dentist will tailor advice specifically for your needs. You’ll learn how to protect and strengthen your enamel at home and prevent future problems.

Frequently Asked Questions
Switch to a soft-bristled toothbrush and use desensitizing toothpaste twice daily. Be gentle when brushing near the gumline. Don’t forget to floss and rinse with a fluoride mouthwash. Avoid acidic and sugary foods and drinks like coffee, soda, wine, and fruit juice—especially before bedtime. If you notice yourself clenching or grinding your teeth, try relaxation or mindfulness techniques to ease jaw tension. Ultimately, a visit to your dentist is essential to find the cause and stop the pain for good.
In some cases, improving your dental hygiene can allow enamel to repair itself, especially with the help of fluoride treatments. However, if the dentin is exposed and decay has progressed, the risk of infection or abscess increases, making professional treatment necessary.
Indirectly, yes. Stress can lead to neglected oral care, poor dietary choices, smoking, or grinding and clenching teeth—often unknowingly during sleep—which all contribute to sensitivity.
Acidic foods wear down enamel, while sweet and starchy foods feed bacteria that produce acids. Hard foods can physically damage teeth. Common culprits include:
-
Acidic: Coffee, wine, fruit juices, citrus fruits, soda, tomatoes, pickles, vinegar
Sweet: Chocolate, jams, caramel, candies, ice cream, sugary drinks
Starches: Donuts, cakes, bread, potato chips, crackers, cookies
Hard foods: Ice, hard candies, popcorn kernels, cherries, olives
You don’t need to avoid these completely—moderation and good dental hygiene are key.
Opt for low-acid, low-sugar options. Foods high in fiber and dairy promote saliva, which protects teeth. Aim for a balanced diet rich in protein and calcium. Examples include:
- Drinks: Water, green tea, black tea
- Snacks: Nuts, raisins, celery, carrot sticks, apple slices, cheese
- Meals: Stir-fries, salads, wraps, meats with vegetables and potatoes
- Desserts: Yogurt, ricotta with berries, applesauce
