Cavities are an extremely common occurrence. It’s almost impossible to reach adulthood without having had at least one cavity. In fact, 92% of U.S. adults ages 20 to 64 have had cavities in their permanent teeth.

Well, did you know they can develop in between your teeth? An interproximal cavity forms when the enamel is worn down, and bacteria stick to the tooth, causing decay. Read on to learn which signs indicate you have a cavity between your teeth and what you can do to prevent them.

What is a Cavity?

Cavities are permanently damaged areas of your teeth that develop into soft spots or holes. They’re a result of tooth decay, an infection that develops from plaque and tartar buildup.

Tooth decay is caused by the overconsumption of sweet and acidic beverages, frequent snacking, and poor dental hygiene. Over time, these habits lead to enamel erosion which allows bacteria to reach and infect your tooth.

Signs You Have a Cavity Between Your Teeth

When found early, cavities can easily be taken care of by your dentist. Knowing the warning signs of a cavity will help you seek treatment before it becomes a severe problem. Here are some symptoms to look out for:

Tooth Sensitivity

Cavities wear away at your tooth’s enamel, causing the nerves underneath to become more exposed. As a result, a common side effect of a cavity is sensitivity to hot or cold temperatures.


No amount of tooth pain is considered normal. So, whether it’s mild or severe, you should contact your dentist right away if you’re experiencing a persistent toothache.

Dark Spots or Holes

These are the most visible signs of a cavity. Dark spots typically occur right before a hole forms within the tooth. If you can feel a hole in your tooth, that indicates the decay is severe and needs treatment immediately. It’s always best to try and catch cavities before they reach this level.


Pus may indicate that an abscess has formed from your cavity. Like the formation of holes, this is a sign that your decay has progressed, and you should seek dental care right away.

Tips to Prevent Cavities

Even though cavities are common, they’re very preventable! Here are a few tips to minimize your risk:

  • Maintain a solid oral hygiene routine. Brush your teeth twice a day and floss once a day to keep your mouth bacteria-free. Use fluoridated toothpaste to strengthen and help remineralize your teeth.
  • Limit your sugar intake. Reducing your consumption of sugary, sweet, or acidic snacks will help lower your chances of tooth decay. Instead, opt for tooth-friendly foods like carrots, apples, and celery.
  • Avoid tobacco products. Smoking and tobacco use can harm your oral health, causing issues like discoloration, decay, and even gum disease. Avoid these products to keep your mouth and body healthy.
  • Regularly visit your dentist. Professional cleanings and routine examinations are essential to keep your oral health in optimal condition. Your dentist can remove plaque and detect any alarming issues early on.

All in all, proper dental care and healthy habits are the key to a healthy mouth. By taking good care of your teeth, you can prevent cavities and enjoy a beautiful smile for a lifetime!
