Dentists know a lot about keeping teeth healthy. They have seen many people with gum disease and cavities. Some habits can harm your teeth, even if you brush and floss regularly. Here are nine things dentists avoid to keep their teeth in top shape.

1. Chewing Ice

Chewing ice is a big no-no. It can break your teeth because it is hard and cold. This is especially bad for people with fillings.

2. Nail-Biting

Nail-biting wears down the enamel on your teeth. Enamel protects your teeth from cavities and sensitivity.

3. Using Teeth as Tools

Using your teeth to open bags or bottles might seem harmless, but it can cause pain or even break your teeth.

4. Eating Sticky Candies

Sticky candies like gummy bears can get stuck in your teeth and cause cavities. They can also pop out fillings. Sour gummies are even worse because they are sticky, sugary, and acidic.

5. Drinking Too Much Alcohol

Drinking too much alcohol is bad for your teeth. It dries out your mouth and reduces saliva, which helps protect your teeth.

6. Using a Hard-Bristled Toothbrush

Using a toothbrush with hard bristles can harm your gums and teeth. Soft bristles are gentler and just as effective.

7. Smoking

Smoking is terrible for your teeth. It can cause discoloration, serious oral health issues, and even oral cancer.

8. Skipping Brushing and Flossing

Skipping brushing and flossing is a major mistake. It is especially important to brush your teeth at night to keep bacteria from growing overnight.

9. Missing Dentist Appointments

Missing dentist appointments is another habit to avoid. Regular checkups help catch dental issues early. How often you should visit the dentist depends on your personal dental history and risk factors. Some people need to go once a year, while others may need to go three or four times a year.
