Tooth decay types

tooth decay
Tooth decay results from an imbalance in the biofilm which is the bacterial plaque covering the surface of our teeth. Due to various factors, certain bacteria develop and transform food residues into acids that destroy the tissues of the tooth.
Tooth decay, therefore, goes through different stages. It first attacks the enamel (the tissue which covers the crown), then the dentin (the tissue under the enamel), finally the pulp which represents the heart of the tooth. Once the pulp is reached, dental sensitivities may appear as well as infections.

Tooth decay types

Intedental decay:

interdental decay

Tooth decay is localized between the teeth. The diagnosis is difficult because decay is not visible. It is detectable only with some tools such as radiography.
The difficulty of analysis of the interdental spaces, as well as the deficiency of cleaning by the patient make the interdental spaces more susceptible to cavities.
This is why daily flossing is important for removing plaque from the interdental spaces and for preventing cavities and periodontal problems.

Smooth surface decay:

This type of caries is superficial, limited to the surface of the tooth: usually develops on the smooth external surfaces of the teeth.
Their evolution is slow and can even be stopped with good oral hygiene.
It is therefore the least serious type of caries.

Pit and fissure decay:

It develops in the chewing surfaces of the molars. They are particularly common in children and adolescents.
The enamel of children and adolescents, being immature, is very sensitive to acid attacks, the progression of caries to the pulp is too fast.
Once the pulp is reached, serious complications can occur, including a dental abscess and periodontal disease.
This type of cavities can be prevented by brushing your teeth thoroughly with the correct techniques.

Root decay:

periapical abscess
Root decay is a type of decay that develops on the tooth root when the gums recede. The root not being covered with email is more fragile and very sensitive to acid attacks.
The acidity released by the bacteria during their metabolism will degrade the components of the dental root causing cavities. These lesions, therefore, evolve more quickly reaching the pulp and destroying the entire tooth.


Complications of tooth decay


To prevent tooth decay, especially if you are at risk
  • Brush with fluoride toothpaste after eating or drinking.
  • Rinse your mouth with natural mouthwashes.
  • Visit your dentist regularly.
  • Drink a lot of water.
  • Balance your diet.
  • Avoid snacking and sipping frequently.
  • Eat healthy foods for your teeth that are rich in minerals and water like green vegetables, cheese, apples, tea, fish...
  • Consider fluoride treatments.
  • Learn about antibacterial treatments. If you're especially vulnerable to tooth decay — for example, because of a medical condition — your dentist may recommend special antibacterial mouth rinses or other treatments to help cut down on harmful bacteria in your mouth.
