4 Things Your Dentist Never Puts in Their Mouth

Dentists spend their days helping patients protect their teeth and gums, so it’s no surprise they’re mindful of their own habits. While no one is perfect, dental professionals tend to avoid certain behaviors that can damage enamel, irritate gums, or increase the risk of oral health problems. If you’re looking to improve your dental habits, here are 4 things your dentist would never put in their mouth and why you shouldn’t either.

1. Ice Cubes

Chewing on ice might seem harmless since it’s just frozen water, but it can actually be tough on your teeth. Ice is hard and brittle, which means biting down on it can cause chips, cracks, or even fractures in your enamel. Over time, this habit can lead to sensitivity or the need for restorative treatments.

Dentists know that enamel doesn’t regenerate, so once it’s damaged, it’s gone for good. If you enjoy cold drinks, it’s best to let the ice melt rather than crunching on it.

2. Sugary and Sticky Candies

Candy is a well-known culprit when it comes to cavities, but sticky varieties like caramels, taffy, and gummies are especially problematic. These treats cling to the surfaces of your teeth and linger in hard-to-reach areas, feeding harmful bacteria that produce acid.

Dentists may still enjoy sweets occasionally, but they tend to avoid sticky candies or consume them sparingly—and always follow up with brushing or rinsing. The longer sugar stays on your teeth, the greater the risk of decay.

3. Acidic Beverages (Sipped Slowly)

Drinks like soda, sports drinks, and even citrus juices are highly acidic. Frequent or prolonged exposure to acid can wear down enamel, leading to erosion and sensitivity. One of the biggest mistakes people make is sipping these drinks slowly over long periods, which continuously bathes the teeth in acid.

Dentists often recommend limiting acidic beverages or drinking them quickly rather than over hours. Using a straw and rinsing with water afterward can also help reduce contact with your teeth.

4. Non-Food Items

Using your teeth as tools is something dentists strongly advise against. Biting fingernails, opening packages, chewing on pens, or holding objects with your teeth can all cause unnecessary stress and damage. These habits increase the risk of chips, cracks, and jaw strain.

Dentists understand that teeth are designed for chewing food—not for handling everyday tasks. Avoiding these habits can go a long way in preserving your smile.

Taking care of your teeth isn’t just about brushing and flossing; it’s also about making smart choices throughout the day. By avoiding habits like chewing ice, overindulging in sticky sweets, sipping acidic drinks for extended periods, and using your teeth as tools, you can protect your enamel and maintain better oral health.
