Cavities don’t always cause obvious symptoms, especially when they form between teeth. These hard-to-see cavities, known as interproximal cavities, can develop quietly and worsen over time if left untreated. Knowing the warning signs can help you catch a problem early and seek dental care before more extensive treatment is needed.
Why Cavities Form Between Teeth
Cavities between teeth occur when plaque and bacteria build up in areas that are difficult to clean. Even people who brush twice a day can develop interproximal cavities if they don’t floss regularly. Sugar and carbohydrates feed oral bacteria, which produce acids that erode enamel and eventually create decay between teeth.
Subtle Sensitivity to Temperature
One of the earliest signs of a cavity between teeth is sensitivity. You may notice a sharp or lingering discomfort when eating or drinking something cold, hot, or sweet. Unlike general tooth sensitivity, this sensation may feel more localized and occur only when certain teeth are involved.
Pain When Flossing
If flossing causes pain, tenderness, or bleeding in a specific spot between two teeth, it could indicate decay or gum inflammation. You might also notice the floss shredding or catching in one area, which can happen when enamel has started to break down.
Food Getting Stuck Frequently
When decay alters the shape of a tooth, food may begin getting stuck between the same teeth repeatedly. If you notice that one spot traps food more often than others and feels uncomfortable or sore afterward, it may be a sign of a developing cavity.
Bad Breath or Unpleasant Taste
A cavity between teeth can harbor bacteria that produce odor-causing compounds. Persistent bad breath or a bad taste in your mouth—especially if it seems to come from one area—may signal decay you can’t see.
Changes You Can’t See in the Mirror
Unlike cavities on the chewing surface or front of a tooth, cavities between teeth are usually invisible without dental X-rays. You may not see dark spots or holes at all, which is why routine dental exams are so important. Dentists often detect interproximal cavities early using bitewing X-rays.
When to See a Dentist
If you experience ongoing sensitivity, discomfort when flossing, or recurring food trapping, schedule a dental visit. Early cavities can often be treated with a small filling, while untreated decay may lead to larger restorations or even root canal therapy.
Cavities between teeth can be easy to miss but costly to ignore. Paying attention to subtle changes and maintaining daily flossing habits, along with regular dental checkups, are the best ways to detect and prevent these hidden cavities before they become serious problems.
