Tooth decay: The basics:

Tooth decay, also known as dental caries or cavities, is a multifaceted process that involves the gradual destruction of tooth structure. It occurs when the bacteria in your mouth interact with sugars and starches from the food you consume. This interaction leads to the formation of acids that attack the enamel, the protective outer layer of your teeth.

The stages of tooth decay:


Tooth decay begins with demineralization, where acids erode the enamel’s minerals. This softens the enamel, making it susceptible to damage.

Cavity formation:

As the enamel weakens, small holes or pits, known as cavities, can form. These cavities are areas of permanent damage to the tooth structure.

Cavity growth:

If left untreated, cavities can continue to grow, affecting deeper layers of the tooth, including the dentin and, eventually, the innermost pulp. This progression can lead to severe pain and infection.

Causes of tooth decay:

Several factors contribute to the development of tooth decay:


The mouth is home to a diverse array of bacteria. Some of these bacteria feed on sugars and starches from food, producing acids that attack the enamel.


A diet rich in sugary and starchy foods provides ample fuel for decay-causing bacteria. Frequent snacking on these foods can also increase the risk of tooth decay.

Poor oral hygiene:

Inadequate brushing and flossing allow plaque to accumulate on teeth. Plaque is a sticky film of bacteria that produces acids, contributing to tooth decay.

Dry mouth:

A lack of saliva can increase the risk of tooth decay because saliva helps neutralize acids and remineralize teeth.

Lack of fluoride:

Fluoride is a natural mineral that can strengthen tooth enamel. Without sufficient fluoride, enamel may be more susceptible to decay.

Preventive measures:

  • Brush your teeth at least twice a day with fluoride toothpaste.
  • Floss daily to remove plaque and food particles from between your teeth.
  • Maintain a balanced diet and limit sugary and acidic foods.
  • Use fluoride mouthwash for additional protection.

Drink plenty of water to help rinse away food particles and acids.
