Decay does not only develop on the biting surfaces of teeth. It can also form in the narrow spaces where teeth touch, an area that is difficult to clean and impossible to see without dental imaging. This type of decay often progresses without obvious symptoms and is commonly found during routine exams.

Can You Get a Cavity Between Teeth?
Tooth decay can develop in the spaces between teeth. These areas trap plaque and bacteria more easily because toothbrush bristles cannot fully reach them. When plaque remains undisturbed, acids gradually weaken enamel and allow decay to form.
How Decay Develops in Tight Tooth Contacts
Plaque builds up naturally throughout the day. When it is not removed from between teeth, bacteria produce acids that erode enamel in these narrow contact points.
Several factors increase risk:
- Inconsistent or ineffective flossing
- Tight spacing between teeth
- Frequent exposure to sugary or acidic foods and drinks (diet)
- Reduced saliva flow
- Weakened or thin enamel
Once enamel damage begins in these areas, progression can occur more quickly than on exposed tooth surfaces.
Signs to Watch For
Problems between teeth often go unnoticed. Visual changes are rare, and discomfort may be subtle.
Possible warning signs include:
- Sensitivity to cold, heat, or sweets felt between teeth
- Discomfort or resistance when flossing one specific area
- Food repeatedly getting stuck in the same spot, and remaining there
- Dark shading near the gumline
- Mild pain when biting or chewing
Symptoms usually indicate that the damage has moved beyond the earliest stage.
How Dentists Identify Decay Between Teeth
A standard visual exam is usually not enough to identify damage in these areas. Dental imaging plays a key role in early detection.
Dentists typically use:
- Bitewing X-rays (digital) to evaluate enamel loss between teeth
- Magnification and focused lighting during exams
- Gentle probing to assess surface changes
Regular exams with X-rays allow issues to be identified before they cause pain or infection.

FAQs
Is a cavity between teeth an emergency?
It is not usually an emergency unless there is severe pain, swelling, or signs of infection. However, this type of decay should be evaluated promptly because it can worsen without obvious symptoms. Eventually, the tooth breaks due to undermining of the decay.
Can you fix cavities between teeth?
How long does it take to fill cavities between teeth?
In most cases, treatment can be completed in a single visit and typically takes less than an hour per tooth.
How do they fill cavities between teeth?
To fill a cavity between teeth, the dentist removes a small amount of tooth structure to access and clean out the decay. Once the decayed area is removed, a tooth-colored filling is placed and shaped to restore the natural contour and contact between the teeth.
