What is cavities between two molars?

The longer the intervention is delayed, the more tooth decay will spread and can penetrate deep into the pulp, making it more difficult to completely cure.

Interstitial tooth decay is very common because these are places where food is easy to trap but difficult to clean. Besides, this location is quite hidden and has many bacteria residing. Detecting cavities between molars is also quite difficult because this location is relatively hidden. Most patients only discover when the decay has eaten quickly and spread, causing damage to both adjacent teeth.

Stages of development of molar interdental caries

Cavities between two molars often progress quite slowly and in stages. You need to determine what stage tooth decay is in to have the most appropriate treatment plan. Below are the mild to severe stages of tooth decay between 2 molars:

  • Enamel decay: This is the first stage of tooth decay. Usually with enamel decay, the dentist will have a treatment regimen that is simple, easy and does not recur. Signs of enamel decay are often yellow or brown streaks in between teeth and tooth edges.
  • Brown dentin worm: At a later stage, when the disease has developed rapidly, the worm has reached brown dentin. With the naked eye, you can distinguish cavities between molars from tiny holes in the teeth.
  • Besides, you may experience more obvious pain and sensitivity. However, the pain does not come often, but will come in waves, accompanied by a sharp feeling, significantly affecting daily eating, especially with hot or too cold spicy foods.
  • Deep dentin caries: This is the most severe stage of interdental caries. At this time, the enamel layer has been completely destroyed and the dentin layer inside can be seen. If the disease has progressed to deep dentin, the patient will feel extremely uncomfortable.

Along with that, pain and sensitivity will come more often even when you don’t eat or drink anything. More seriously, some cases of deep dentinitis have progressed to other healthy teeth.

Causes of interdental caries

To have a suitable and effective treatment plan for cavities between two molars, you need to determine the cause of your disease. Below are some of the leading causes of molar cavities researched and verified by experts:

Dental care is substandard

The main cause of tooth decay in general and cavities between two teeth in general is the oral hygiene process. It can be said that oral hygiene determines up to 90% of whether teeth are healthy or not.

Oral hygiene here includes many different tasks, not just brushing your teeth every day. You should maintain the habit of brushing teeth regularly and combine scaling, rinsing with antiseptic solution, using water floss, dental floss, etc.

If you do not take care of your teeth and ensure thorough cleanliness, leftover food will get stuck in between your teeth and cause cavities. Initially, cavities are just small spots, but over time, bacteria grow and damage the enamel between teeth, making the treatment process even more difficult.

Daily diet

Eating habits with lots of sweets, carbonated drinks, colorants, etc. are all factors that cause cavities between molars. These are all foods that contain ingredients that are not good for oral health.

In addition, food particles and chemicals in the food groups mentioned above are often easily trapped on teeth to create favorable conditions for bacteria to penetrate and develop disease. Not only tooth decay, but many other oral diseases such as periodontitis, gingivitis, etc. 

Habit of using bamboo toothpicks to floss teeth

For a long time, bamboo toothpicks have always been popular to remove leftover food stuck between teeth. However, using toothpicks is not good for oral health if used long term. Because bamboo toothpicks are hard, using them too often will create gaps between teeth. Food can therefore easily be tied up, creating a favorable environment for bacteria to grow and cause disease.

Do not treat other oral diseases thoroughly

Some other oral diseases such as gingivitis, periodontitis, bad breath, etc., if not completely treated, pose a potential risk of tooth decay. Because bacteria still reside here, when met with the right conditions, they will attack between teeth and cause disease quickly.
