How to Prevent and Treat Dental Cavities, Complete Guide

Published on July 4, 2026 | Aster Smiles Dental Clinic, Abuja

What Are Dental Cavities?

Dental Caries (commonly known as tooth decay or cavities) is one of the most common dental diseases worldwide, including in Nigeria.

Dental caries is the gradual destruction of the hard tissues of the teeth (enamel and dentin) caused by acids produced by bacteria in the mouth.

Causes of Dental Cavities

Poor oral hygiene Not brushing twice a day allows plaque to build up on the teeth. Skipping flossing leaves food particles and bacteria between teeth and along the gum line areas where cavities commonly start.
Frequent consumption of sugary and acidic foods/drinks Sugary snacks, soft drinks, juices, sweets, and even starchy foods are major contributors. The more frequently you consume these, the longer your teeth are exposed to acid attacks. Sipping sugary drinks throughout the day is particularly harmful. Therefore stay away from cariogenic diets
Dry mouth Saliva naturally washes away food particles and neutralizes acids. Conditions that reduce saliva increase the risk of caries.
Bacteria (Streptococcus mutans) The bacteria naturally present in your mouth (especially Streptococcus mutans) feed on sugars and starches from the food you eat. These bacteria produce acids as waste. The acid attacks the tooth enamel and gradually dissolves its minerals, leading to decay.

The 5 Essential Factors That must be present before any Tooth Decay (Dental Caries)

Tooth decay doesn’t happen by chance. According to dental science, all five of these factors must be present for dental caries to develop:

1. Susceptible Tooth (Host)

The tooth itself must be vulnerable — either due to weak enamel, deep grooves(pits and fissures), or poor mineralization.

2. Cariogenic Diets

Sugary diets that Harmful bacteria (especially Streptococcus mutans)can feed on to produce acids that deminarilises and crates hole in the teeth/cavity.

3. Cariogenic Bacteria

Especially Streptococcus mutans, Frequent intake of sugars and starches that the bacteria feed on to produce harmful acids.

4. Time

Enough time for the acid attacks to repeatedly demineralize the tooth enamel. This further shows the importance of brushing twice daily to prevent the bacteria from having enough time to act on the cariogenic diets. Brushing will sweep both the bacteria and food debris away

5. Reduced Saliva Flow

Low saliva production (dry mouth or xerostomia) reduces the mouth’s natural ability to neutralize acids and wash away food particles.

Important: Removing or controlling any one of these five factors can stop or prevent tooth decay.
