What is Dental Caries?

Dental caries is a process in which the hard structure of the tooth (enamel and dentin) gets damaged due to acid produced by bacteria.

When you eat sugary or starchy foods, bacteria in the mouth break them down and produce acids. These acids gradually destroy the tooth surface, leading to cavities.

If not treated early, the decay can reach the inner pulp of the tooth and cause severe pain.

Causes of Dental Caries

1. Poor Oral Hygiene

Not brushing and flossing properly allows plaque to build up on teeth. Plaque contains bacteria that produce acids and damage enamel.

2. Sugary and Sticky Foods

Frequent consumption of sweets, chocolates, soft drinks, and sticky foods increases the risk of cavities.

These foods stick to the teeth and provide fuel for bacteria.

3. Frequent Snacking

Eating frequently without cleaning the mouth gives bacteria more time to produce acid.

4. Dry Mouth

Saliva helps wash away food particles and neutralize acids. Reduced saliva increases the risk of decay.

5. Lack of Fluoride

Fluoride strengthens tooth enamel and prevents decay. Lack of fluoride increases cavity risk.

Stages of Dental Caries

Dental caries develops gradually in stages:

1. Initial Demineralization

White spots appear on the tooth surface due to mineral loss.

2. Enamel Decay

The enamel begins to break down, forming small cavities.

3. Dentin Decay

Decay reaches the dentin layer, causing sensitivity and discomfort.

4. Pulp Infection

The infection reaches the inner pulp, causing severe pain and swelling.

5. Abscess Formation

A pus-filled infection develops, which may require urgent treatment.

Symptoms of Dental Caries

Common symptoms include:

• Toothache or pain
• Sensitivity to hot or cold
• Pain while chewing
• Visible holes or dark spots on teeth
• Bad breath
• Swelling in gums

Early stages may not show symptoms, which is why regular dental checkups are important.

Risk Factors for Tooth Decay

Some people are at higher risk of developing dental caries:

• Poor oral hygiene habits
• High sugar diet
• Children and elderly individuals
• Dry mouth conditions
• Smoking and tobacco use
• Lack of regular dental visits

Treatment Options for Dental Caries

Treatment depends on the severity of the decay.

1. Fluoride Treatment

In early stages, fluoride can help repair enamel and reverse damage.
