TOOTH SENSITIVITY TO COLD: CAUSES AND SAFE WAYS TO HANDLE IT
- INTRODUCTION
Enjoying a cold treat like ice cream or a smoothie should be fun—but for many people, it can be painful. That sudden, sharp pain in your teeth when eating or drinking something cold is a common issue called tooth sensitivity. About 1 in 8 people in the U.S. experience it.
Tooth sensitivity happens when the inner layer of the tooth, called dentin, gets exposed. Dentin lies beneath the enamel and surrounds the nerves in your teeth. In some cases, treatments like Invisalign can help align teeth in a way that reduces abnormal wear on enamel. When enamel is damaged or worn away, dentin is no longer protected. This causes pain when it comes into contact with cold (or hot) foods and drinks.
- COMMON CAUSES OF TOOTH SENSITIVITY TO COLD
- Untreated Tooth Decay: Tooth decay begins with tiny holes or weak spots in your enamel. These may not be visible, but bacteria can pass through and reach the dentin. Once this happens, your teeth can become sensitive, especially to cold air or cold food.
- Brushing Too Hard or Using a Hard Toothbrush: Brushing your teeth is important, but brushing with too much pressure or using a hard-bristle brush can damage the enamel. This makes it easier for bacteria to cause sensitivity and decay. Also, using toothpicks can scratch the enamel. Dentists recommend using soft toothbrushes and dental floss instead of toothpicks.
- Teeth Grinding (Bruxism): People who are stressed or anxious may grind their teeth, often without realizing it. This pressure erodes the enamel over time. The roots show if the gums pull back, or recede.
- Cracked or Chipped Teeth: Accidents, biting hard foods, or using your teeth as tools can cause cracks or chips. Even small cracks can allow cold substances to reach the dentin, leading to sharp pain and even a risk of infection.
- Exposed Tooth Roots: The roots of your teeth are normally protected by your gums and a layer called cementum. If the gums recede (pull back), the roots become exposed. Since the roots contain nerves, this can lead to strong sensitivity. Gum recession can be caused by brushing too hard, smoking, or gum disease.
- Teeth Whitening Treatments: Whitening products, especially those with hydrogen peroxide, can cause short-term sensitivity. They may temporarily remove minerals from your enamel. The good news is that drinking fluoridated water and eating foods rich in fluoride can help restore these minerals.
- HOW TO TREAT TOOTH SENSITIVITY
If you have sensitive teeth, it’s important to visit a dentist. At Locust Family Dentistry, several treatments can help relieve your pain and protect your teeth. These include:
- Tooth fillings for decayed or damaged teeth
- Fluoride treatments to strengthen enamel
- Dental bonding to cover exposed areas
- Advice for at-home care, like using special desensitizing toothpaste
No one should suffer from tooth pain. With the right treatment and care, you can enjoy cold foods again without worry.
