Cavity Between Teeth: What You Need to Know

A cavity between teeth is referred to as an interproximal cavity. In the same way as other dental cavities, interproximal cavities can be formed when the enamel wears away, and bacteria sticks to the tooth, causing decay. Tooth decay is one of the most common dental problems. It is estimated that approximately 80% of people will develop a cavity by the time they reach their 30s. The interproximal cavity is difficult to spot because it is located between the teeth.

This article will explore all about the cavity between teeth, signs of cavity, how to treat them.

What is a Cavity?

Cavities are spots of decay on the chewing surface, between teeth, or along the gum line. You get them when food debris and bacteria build up in your mouth, forming plaque, which erodes your enamel.

Cavities develop as the enamel erodes and decay moves to the dentin, then into the pulp chamber. Cavities are holes or pits in the teeth that form holes.

Cavities can cause infections, abscesses, and tooth and bone loss if not treated. If you keep your teeth clean and get regular dental care, you can prevent most cavities, and if you catch them early, they can be treated.

You can get cavities no matter what you eat or how often you brush, but some people are just more prone to them than others. Everyone gets cavities, so knowing what they are and how to spot them is a good idea.

Sign of Cavity Between Teeth?

The severity and location of tooth decay determine the signs and symptoms of tooth decay. You may not experience any symptoms at all in some cases. The following symptoms may occur as the decay spreads:

  • Toothache
  • Sensitivity
  • Mild to sharp pain when eating something cold, hot, or sweet
  • Visible holes/pits in tooth
  • Staining on the surface of the tooth
  • Pain when biting down

It’s possible to miss an interproximal cavity because of its location. A dentist or hygienist may detect it on an X-ray before it spreads.

How Do I Prevent a Cavity Between Teeth?


The bacteria and plaque between your teeth cannot be effectively cleaned by brushing alone, which can result in interproximal cavities. Keep your teeth clean and cavity-free by using dental floss between your teeth once a day.

Additionally, your dentist may recommend reducing your intake of sugary foods and drinks and limiting your snacking between meals to prevent cavities. Additionally, they might recommend reducing or eliminating alcohol consumption and smoking.

How Can Cavities Between Teeth Be Treated?

After knowing the sign of cavity between teeth, we explore the treatments. A variety of treatment options are available to treat an interproximal cavity, depending on its severity.


Using fluoride gel to recalcify a tooth is an option if the cavity is detected early and does not extend into the enamel.

Dental Filling

When the cavity extends deeper into the enamel, a dental filling can be used to restore appearance and function. After the decay is drilled out, a composite resin, porcelain, amalgam, gold, or silver filler will be applied.

Root Canal Treatment

If an untreated cavity is left untreated for a long time, it can damage the dental pulp, the tooth’s center. It’s best to get root canal therapy if this happens. In this procedure, the pulp is removed from the tooth. To support the tooth from the inside, the inside of the tooth will be disinfected and filled with a biocompatible material. Afterwards, a dental filling will seal the tooth, and, if necessary, a crown will protect it.

Dental Crown

Dental crowns protect damaged/decayed teeth by covering them with a cap. The crown protects the structure of the tooth after a root canal treatment or in the case of large cavities that cannot be filled with dental fillings. A dental crown can be made from porcelain, metal, porcelain-fused-to-metal, or composite resin, among others.


When possible, your dentist will try to save the natural tooth. In some cases, extraction is the only option, especially if the infection threatens to spread into the jawbone. A simple extraction is one type of extraction, while a surgical extraction is another. To avoid further problems, you should replace the space left by the extracted tooth as soon as possible with a dental implant, a bridge, or a partial denture.
