What causes sensitive teeth? Is it related to tooth problems, gum disease, aggressive brushing, or what I eat? The leading causes of sensitive teeth may not be what you think!
People with sensitive teeth know the dull ache or sharp pain that can result from hot or cold exposure. That sensitivity can be brought on by cracked teeth, tooth decay, or gum disease. It could also be related to aggressive or abrasive brushing. But most often, the cause of sensitivity is exposure to acidic foods, drinks, or stomach acid from acid reflux/GERD that wear down the tooth enamel over time.
Beverages like energy drinks, soda, seltzers, wine, and juice — all are acidic and can steal minerals from your enamel. The loss of mineral can erode enamel and make tooth enamel weak, sensitive, and prone to decay.
“Some people seem to be able to eat whatever they want, while others eat fresh pineapple for breakfast and experience sensitive teeth within hours,” says Dr. Ashley Kerslake of Dental Health Partners. “If you are prone to sensitive teeth, there are steps you can take to reduce tooth sensitivity, from using products designed for tooth sensitivity to rinsing your mouth with water after eating certain foods.”
Dr. Paula says that sensitive teeth may also be related to gum disease, when the gums retract and expose more sensitive parts of the tooth. Cracked teeth can cause something similar to root exposure.
“Even a tiny crack can make teeth vulnerable and more sensitive—especially to cold temperature drinks and foods,” says Dr. Paula Kral, owner of Dental Health Partners in Cedar Rapids. “So it’s important to treat bruxism, which is tooth grinding. Bruxism is a common cause of cracked teeth.”
Finally, tooth decay can cause sensitivity to eating sweet foods. If you have a sharp sensation in a specific tooth when you eat something, you should see your dentist to get checked out for a cracked or decayed tooth.
Note: Tooth whitening can also cause tooth sensitivity, but today’s tooth whitening products often include ingredients to counteract that effect.
Drinks and Foods That Affect Tooth Enamel
The erosion of tooth enamel is a leading cause of sensitive teeth, and many foods and beverage trends can cause demineralization and deterioration of the enamel. To different degrees, the following foods and beverages can affect tooth enamel, which can make teeth more sensitive. You may look at this list and wonder what you CAN eat without affecting your tooth enamel. Don’t worry — there are a couple of simple methods you can use to counteract the effect of these foods. Regular oral care, like brushing teeth, flossing teeth and gums, and using mouthwash, can help.
To reduce tooth sensitivity related to food and drinks, be mindful of your intake of the following acidic items:
- Sugary drinks
- Soda
- Seltzer
- Wine
- Beer, especially sour beers
- Hard alcohol
- Fruit juice
- Fruits, especially citrus
- Sauerkraut and other pickled items
Do not sip! Dr. Paula says to drink your favorite beverages and be done with them rather than sipping on them all morning or evening.
Simple Ways to Desensitize Teeth
No one wants to give up their favorite foods and beverages because they cause sensitive teeth. As we know, citrus fruits and other acidic fruit are packed with nutrition! If your teeth are sensitive, you may be able to counteract some of the effects of acidic foods and drinks.
The first action to take is to rinse your mouth with water after eating or drinking acidic or sugary items. This washes away the acids and, if it is fluoridated water, it can help remineralize and strengthen your teeth. You can also brush your teeth soon after a meal or drink. Dr. Ashley and Dr. Paula can recommend toothpaste for sensitive teeth and provide you with a sample.
Remember to do the following if you have sensitive teeth:
- Use a straw to drink juice, soda, or seltzer to minimize beverages directly contacting teeth.
- Rinse with water after eating and drinking
- Brush at least 2 times a day with fluoride toothpaste designed for sensitive teeth and a soft bristle toothbrush
- Floss regularly to prevent gum disease
- Drink water or green tea, which are both good for your teeth
Many people develop sensitive teeth over time, so Dental Health Partners encourages you to address sensitive teeth at your dental visits. By learning more about sensitive teeth, acting early to address sensitivity, and regularly brushing and flossing, you can avoid this annoying issue becoming a painful problem at every meal.
Ask Dr. Paula and Dr. Ashley for product recommendations, like mouthwashes and toothpaste, so you can enjoy nutrient-dense foods like fruit and other enjoyable foods and beverages. Make your appointment to talk about tooth sensitivity.
