How to Treat Cavity in Between Teeth

Ever wondered how to treat cavities in between teeth?

Cavities are caused by tooth decay, and they develop when food is allowed to decay on your teeth.

Bacteria in plaque on your teeth break down sugar, producing acid. The acid demineralizes your teeth’s enamel or protective outer layer. It can cause a cavity if not stopped.

An interproximal cavity is a space between two teeth, whether they are molars or other teeth. If you’ve ever had a cavity, you’ve probably had an interproximal cavity.

Like any other cavity, an interproximal cavity develops due to one or more teeth enamel, the tooth’s outer layer, wearing down.

This article will go over what an interproximal cavity feels like and how it can be treated.

Symptoms of Cavity Between the Teeth

A cavity can cause various symptoms and signs, which vary depending on the extent and location of the cavity. It is possible to have no symptoms during the early stages of cavity development. As the decay progresses, you may notice the following signs: 

  • Toothache, spontaneous pain, or pain that suddenly appears for no apparent reason
  • Sensitivity of the teeth
  • Pain ranges from mild to severe when you eat or drink something sweet, hot, or cold.
  • Visible pits or holes in your teeth
  • Stains on any surface of a tooth that is brown, black, or white
  • When you bite down, you feel pain.

The cavity passes through the enamel and into the dentin, the second layer of tissue. 

This can cause tooth sensitivity to sweets and cold and chewing discomfort.

The cavity is typically discovered by your dentist or dental hygienist using a bitewing X-ray.

How to Treat Cavity in Between Teeth

Regular dental checkups can help detect cavities before they cause more serious issues that can lead to long-term issues.

Now, we’ll focus on a few of the cavity-related treatment options to consider.


An organic procedure for mending teeth is remineralization. Your body deposits calcium and phosphate minerals from your saliva in your enamel.

Your teeth lose minerals as you eat and drink throughout the day, a process known as demineralization.

Natural tooth demineralization occurs. When your body is unable to replace what you lose, it can become a problem.

Mouth bacteria, mouth acid, and saliva are all factors that influence demineralization.

Remineralization replaces lost minerals in the teeth, keeping them strong and preventing tooth decay.

Remineralization agents help the enamel absorb minerals like calcium and phosphate, which strengthens it.

Fluoride, which is a mineral added to water to prevent tooth decay, also binds to enamel, making it more resistant to acid destruction.

A cavity develops when there is more tooth demineralization than demineralization.

Tooth Fillings

A filling is a procedure performed in the dentist’s office. A numbing gel is applied to the gums by your dentist. After this has taken effect, a local anesthetic is injected into the gum.

The dentist will then remove the decayed area of the tooth and fills the hole in the tooth with a drill or another specialized tool. The final step is to polish and adjust the filling so that your bite feels natural.

After the dentist removes the decay, a filling is placed to restore function, and aesthetics, and to aid in the prevention of further tooth damage and tooth loss. A filling is a dental restoration that fills a hole/cavity in the tooth.

When considering tooth fillings, you should be aware of the various types available, including:

Amalgam Fillings

Fillings made of silver, tin, copper, and mercury are known as amalgam fillings. It is tough, durable, and less expensive than other types of fillings.

Composite Fillings

Composite fillings are composed of resin and plastic. It is softly placed into the cavity and then hardened with a bright blue “curing” light.

Glass Lonomer Fillings

Glass ionomer fillings are composed of glass and acrylic. They are weaker, which makes them preferable for children whose teeth are changing.

Gold Fillings

As the name implies, these are made of gold. Gold fillings are extremely durable, but they are also very expensive, so they are not widely used.

Root Canal

When a tooth or its root is damaged by trauma, you may experience pain and increased sensitivity in that tooth.

When you bite down, you may experience frequent pain, which may indicate that your tooth requires root canal therapy.

When a cavity reaches the pulp (the chamber in the tooth containing the nerve and blood vessels), root canal therapy may be required to repair and save a badly damaged or infected tooth rather than remove it.

The infected tooth pulp is extracted. To clear any infection, medication is sometimes inserted into your root canal.

The pulp will then be replaced with a filling. Potential infections and dental abscesses are also treated.

Dental Crown

Teeth can become damaged over time. This can occur for a variety of reasons, including cavities caused by tooth decay. Dental crowns are “caps” that fit over your teeth and have the shape of teeth. 

A dental crown is cemented onto your tooth, covering the visible portion of the tooth.

You may require a dental crown for a variety of reasons, including:

  • Keeping a weak tooth from breaking (possibly due to decay or cavities) or holding a weak tooth together if parts of it are noticeably cracked.
  • Repairing a broken or severely worn down tooth
  • A large filling covering and supports a tooth with little tooth remaining.
  • Covering up crooked or discolored teeth.
  • Protecting a vulnerable tooth that has been treated with a root canal.


Cavities can cause teeth to be so badly damaged that extraction is the only option.

This is typically the case with severe cavities when the tooth has been so badly damaged by the cavities that it cannot be repaired and must be extracted.

The root must be extracted, also known as pulling.

Tooth extraction is a relatively simple process that involves the use of local anesthesia to numb the area.

The whole tooth, including the root, will then be extracted by your oral surgeon.

In some cases, the bone grafting material will be placed in the extraction socket. The entire process takes around an hour on average.

Prevention Of Cavity Between the Teeth

There are a lot of routines that can be followed to help prevent cavities. The first step is to practice good oral and dental hygiene. Consider some of the following suggestions:

Ensure you brush your teeth with a fluoride toothpaste at least twice a day, preferably after each meal. Ensure that you floss between your teeth.

  • Use a fluoride mouth rinse.
  • Maintain regular check-ups with your dentist.
  • Maintain a tooth-friendly diet. Avoid foods that get stuck in your teeth’s grooves and pits. Fresh fruits and vegetables increase saliva flow, which is beneficial for oral hygiene.

Avoiding interproximal cavities with just brushing can be challenging because your toothbrush can’t remove the bacteria and plaque between your teeth.

Once a day, flossing between your teeth will help keep the crevices and cracks between your teeth clean and cavity-free.

It is important to note that to reduce your chances of getting a cavity, your dentist might also advise you to limit your intake of sugary foods and drinks and between-meal snacking.

They may also advise you to reduce or stop smoking and drinking alcohol.

How to Get Rid of Tooth Cavity at Home

A lot of home remedies are based on a 1930s study that suggested that a lack of vitamin D in the diet causes cavities.

In this study, children who consumed more vitamin D had fewer cavities. However, the best outcomes were noticed in those who increased vitamin D while cutting out grain-based foods.

This could be because grains can sometimes stick to the teeth.

A lack of vitamin D could also make your teeth more prone to cavities, but we now know that this is only a piece of the puzzle. Another risk factor for cavities is:

  • Dry mouth or having a medical condition that reduces the amount of saliva in your mouth
  • Eating foods that cling to your teeth e.g. candy and sticky foods
  • Frequent snacking on sugary foods and drinks, like cereals, soda, and ice cream
  • heartburn 
  • inadequate tooth hygiene
  • bedtime infant feeding

Chewing Sugar-Free Gums

Clinical trials have shown that chewing sugar-free gum after meals can help remineralize enamel.

Long-term studies are needed to determine the ability of xylitol-containing gum to stimulate saliva flow, raise plaque pH, and reduce S. mutans.

Chewing gum without sugar that contains the substance casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has been shown to lessen S. mutans even more than gum that contains xylitol.

Scrap out Sugar

Cutting out sugar is the number one remedy that no one wants to hear.

Now, according to the World Health Organization, the most important cause of tooth cavities is eating sugar.

The WHO recommends keeping your daily sugar intake to about less than 10 percent of your total caloric intake.

If you’re going to consume sugar, you should try not to do so throughout the day.

When the sugar is gone, your teeth’ enamel can remineralize.

However, if you like to consume sugar on a regular basis, your teeth will not have the opportunity to remineralize.


Cavities are permanently damaged parts of your teeth’s hard surface. Bacteria and poor oral hygiene contribute to them.

An interproximal cavity is one that develops between two teeth, whether they are molars or other teeth.

If you’ve ever had a cavity, you’ve probably had an interproximal cavity.

Interproximal cavities form similar to other types of cavities due to enamel wear on one or more teeth.

Cavities can be treated in a lot of ways, including fillings, root canals, and crowns.

In cases where cavities have severely damaged the tooth, extraction may be the best option to consider.
