Ice cream on a hot summer's day can be a tasty way to beat the heat, but if you're one of the millions of people who have sensitive teeth, that cold treat can really hurt. So, what makes your teeth dread cold, delicious treats, or a good cup of hot coffee on the other hand?
What causes sensitive teeth?
Teeth are complicated, and when we use them, the enamel that protects our teeth wears down. When the inner layer of the tooth is exposed to the oral environment, there is access to the dentinal tubes. Hydrodynamic fluid movement, triggered by stimuli within the dentinal tubes, stimulates the nerve and produces a pain response.
The most common factor associated with tooth sensitivity is gum recession. If the gums begin to waver, the root of the tooth is exposed, causing sensitivity. Other causes of tooth sensitivity include toothbrush abrasion, periodontal treatment, tooth decay or defective restorations, excessive grinding or excessive whitening.
What you eat and drink can also make your teeth more sensitive. Soft drinks – diet as well as regular drinks, fruit juice, wine and coffee can make your teeth sensitive. Acidic foods, such as citrus fruits, are also active in this sense, but less than with liquids.
Sensitive teeth and chills Despite how it may feel, the cold weather actually affects your sinuses, not your teeth, at least not directly. Changes in atmospheric pressure can cause pressure in the sinuses that lie above the upper back teeth. The sinus pressure can lower the pain threshold for these teeth making them more sensitive to external stimuli-like cold water or air. This can make everyday activities, such as running, difficult in cold weather without leaving you feeling sore in your mouth. But luckily there are ways to compensate for your sensitive teeth and conquer the elements again.
Treatment of sensitive teeth
Having sensitive teeth can be very annoying. It's easy to enjoy an ice cream, exercise in cold weather, or use your favorite whitening toothpaste. Fortunately, there are ways to sensitize your teeth.
There are several toothpastes that have potassium nitrate or calcium phosphate that can help with sensitivity in daily use. Using fluoride gels and rinses is also helpful for sensitivity. Be sure to use a soft-bristled toothbrush or mechanical toothbrush to aid the pressure when brushing.
If you can't treat sensitive teeth at home using pharmacy products, there are ways you may be able to improve your sensitive teeth at the dentist.
