Cavities between the teeth, also known as interproximal cavities, are one of the most common yet hardest to detect dental issues. Unlike cavities on the chewing surface of your teeth, these hidden spots often go unnoticed until the decay has progressed significantly. So how do you know if you have a cavity between your teeth? Understanding the signs and seeking regular dental care is key to catching them early and avoiding more serious problems.
What Causes Cavities Between Teeth?
Cavities form when plaque, a sticky film of bacteria, builds up on the teeth and produces acids that erode the enamel. When plaque accumulates in hard-to-reach areas—especially between the teeth—it’s easier for decay to take hold. Poor flossing habits, frequent snacking on sugary foods, and skipping dental cleanings all increase your risk of interproximal cavities.
Common Signs of a Cavity Between Your Teeth
Because you can’t always see or feel a cavity between your teeth, it’s important to pay attention to the following symptoms:
Tooth Sensitivity
If you feel a sharp or lingering pain when eating something hot, cold, or sweet, it could be a sign of a cavity. This sensitivity often indicates that the protective enamel is worn down, allowing stimuli to reach the inner layers of the tooth.
Pain When Chewing
Discomfort when biting or chewing food—especially between two specific teeth—can suggest that decay is affecting the area. If the cavity has advanced, it may irritate the nerve of the tooth, making chewing painful.
Bad Breath or a Bad Taste
Cavities harbor bacteria, which can produce a foul smell or taste in your mouth. If you notice persistent bad breath despite good oral hygiene, a hidden cavity may be the culprit.
Visible Dark Spots or Gaps
While interproximal cavities are usually hidden, they can sometimes be seen as dark areas or shadows between the teeth, especially if the cavity has grown larger.
Food Getting Stuck Between Teeth
If food suddenly begins to stick between two teeth where it didn’t before, a cavity may have created a gap or rough edge.
How Dentists Diagnose Interproximal Cavities
Cavities between the teeth are often difficult to detect without a professional dental exam. Dentists use a combination of visual inspection and dental X-rays to identify these types of cavities. Bitewing X-rays are particularly effective at revealing decay between teeth, even in its early stages.
Prevention Tips
- Floss daily: Flossing is the best way to clean between your teeth and prevent plaque buildup that leads to cavities.
- Brush with fluoride toothpaste: Fluoride strengthens enamel and helps fight early decay.
- Avoid frequent snacking: Especially on sugary or starchy foods that feed harmful bacteria.
- Visit your dentist regularly: Dental checkups every six months can catch cavities early and prevent them from worsening.
Interproximal cavities can be sneaky, but they’re not impossible to detect. If you notice sensitivity, pain, or food sticking between your teeth, it’s time to schedule a dental visit. Early detection and treatment can save you from more serious dental issues down the road.
