When it comes to foods that dentists dislike, most people think of sweets or carbonated drinks, but there are many unexpected foods.

I became curious and searched for the foods that dentists particularly dislike.

The first is ice.

Ice may seem healthy as it has no sugar and no calories, but it is a disaster for teeth. The moment you bite into hard ice, the enamel on the surface of your teeth can micro-crack, allowing bacteria to invade and cause gum inflammation or sensitivity.

Especially for those undergoing orthodontics or with implants, the habit of chewing ice can lead to breakage or cracks. It is better to let ice melt in your mouth or use a straw to avoid keeping it in your mouth for too long.

The second is popcorn, which many people enjoy while watching movies.

Popcorn itself is made from corn and seems harmless, but the problem lies with the 'unpopped kernels.' Chewing on these hard kernels can often lead to broken teeth or damaged gums. Additionally, popcorn husks can easily get stuck between teeth, causing discomfort and potentially leading to inflammation inside the gums. It is better to enjoy popcorn carefully, as if melting it in your mouth.

The third is rice cakes, which surprisingly many people enjoy without hesitation.

Rice cakes are a representative snack for Koreans, but from a dental perspective, they are the worst sticky enemy. Chewy rice cakes stick to the surface of teeth and do not easily come off, creating a favorable environment for cavity-causing bacteria. Especially types like injeolmi or chewy rice cakes can get deeply stuck between teeth, making them difficult to remove with regular brushing. Dentists recommend using dental floss or a water flosser after eating rice cakes.

The fourth is dried fruits, often mentioned as 'healthy snacks.'

Dried fruits like mango or raisins are sweet and chewy, rich in vitamins, but the high sugar and stickiness are problematic. When they stick to teeth, they create an acidic environment that weakens enamel. It is much better to eat fresh fruits instead.

Another surprising culprit is acidic drinks like vinegar or lemon water. Popular as a healthy habit to drink on an empty stomach, the acidic components can erode the surface of teeth, increasing sensitivity. Dentists recommend not brushing immediately after consuming such drinks, but rinsing with water and waiting about 30 minutes before brushing.

Finally, carbonated water and energy drinks should also be approached with caution. Even without sugar, their high acidity can weaken teeth.

Ultimately, the key to maintaining dental health is to be cautious of 'hard, sticky, and acidic' things.

It is important not to chew ice, to be careful with popcorn, and to thoroughly clean your teeth after eating rice cakes.

Once teeth are damaged, they do not naturally regenerate.
