Cavities are among the most common dental issues, but not all of them are easy to detect, especially when they form in hidden areas. One sneaky location where decay can develop is between the teeth, known as an interproximal cavity. These types of cavities often go unnoticed until they’re more advanced, but there are some signs to watch for that may indicate a problem is forming where your toothbrush can’t easily reach. Here’s how to tell if you might have a cavity between your teeth and what to do about it.
Increased Sensitivity to Hot, Cold, or Sweet Foods
One of the earliest signs of a cavity between your teeth is sensitivity. You may notice a twinge or ache when drinking cold water, sipping hot coffee, or eating sugary snacks. This occurs when decay starts to wear down the enamel and exposes the more sensitive layer underneath (called dentin).
If you notice recurring sensitivity in a specific spot, especially when chewing or brushing, it’s time to let your dentist know.
Difficulty Flossing or Catching Snags
If floss suddenly starts to tear or catch between two teeth, or you feel unusual resistance when trying to glide it through, that could be a sign of a cavity or rough surface. While it might also be due to tartar buildup or crowded teeth, it’s worth checking out, especially if it’s accompanied by bleeding or discomfort.
Discomfort or Pain While Chewing
When cavities between teeth grow deeper, they can cause toothaches or sharp pain when biting down or chewing. This discomfort is often localized and may feel like pressure or a dull ache between specific teeth. You might also notice pain that comes and goes, especially when eating harder foods.
Visible Discoloration or Shadowing
Sometimes you can actually see signs of a cavity developing between teeth, especially if it’s toward the front of your mouth. You may notice a dark spot, discoloration, or shadow along the side of the tooth near the gumline. However, because interproximal cavities are often hidden from plain sight, they’re usually diagnosed through dental X-rays.
Bad Breath or Unpleasant Taste
As bacteria accumulate in the decayed area between your teeth, you may develop persistent bad breath or a bad taste in your mouth, even after brushing. This is a sign that decay has progressed and should be evaluated promptly.
How Dentists Detect Cavities Between Teeth
Because these cavities are so well-hidden, your dentist uses bitewing X-rays to detect them. These images help reveal decay forming between tooth surfaces long before it causes pain or becomes visible.
Regular dental checkups are key to catching interproximal cavities early, while they can still be treated with a simple filling rather than more complex procedures like crowns or root canals.
Cavities between teeth can be tricky to spot on your own, but knowing the warning signs can help you catch them early. If you notice sensitivity, pain when chewing, flossing difficulties, or persistent bad breath, it’s time to schedule a dental visit.
