Interproximal Cavity: Symptoms, Treatments & Prevention Tips

How To Know If You Have A Cavity In Between Teeth

If you are unsure whether the sudden brown spot between your teeth is a cavity or something else, a few indications can help. The following symptoms will occur if you are dealing with an interproximal cavity:

  • Since the cavity penetrates the enamel and reaches the dentin layer, you will feel increased tooth sensitivity. Hence, your tooth might hurt or exhibit discomfort when it comes in contact with something sweet, hot, or extremely cold.
  • You will experience a constant toothache in the affected area.
  • The color of your tooth will alter; you will notice a brown or black spot between your teeth.
  • Eating or biting down will aggravate the area and cause pain.
  • A hole or pit will appear on the tooth. This is because, unfortunately, the cavity in between teeth is usually hard to spot due to its location. Thus, you might know you have a cavity when it spreads and causes discomfort.

Cavity In Between Teeth Treatment

If you suspect a cavity between your teeth, it is best to approach a dental professional. This is because you cannot reverse tooth decay at this stage, and only professional treatment can stop a cavity in between your teeth.

Here are a few professional treatments for cavities between teeth:

  1. Dental Filling: Your dentist might recommend a dental filling if the cavity has extended more than halfway into the tooth enamel. This procedure can help restore the normal shape and function of the tooth.
  2. Root Canal: Sometimes, the cavity can lead to an infected tooth. In such instances, you will require a root canal treatment to clean out the infected tissue. Then, a biocompatible material will be used to fill the tooth, strengthening it.
  3. Crown: If you have severe decay, a dental crown might be a suitable choice. It helps restore the tooth to its normal shape while offering protection against additional damage.
  4. Extraction: It’s possible that the damage is too severe for any restoration procedure to save the tooth. If that’s the case, your dentist might recommend tooth extraction to prevent further complications.
