The Truth About Cavities: How They Start and How to Stop Them

Cavities are one of the most common dental problems worldwide, yet many people don’t fully understand how they develop or what can be done to prevent them. Let’s break down what cavities really are, how they start, and the most effective ways to stop them in their tracks.

What Exactly Is a Cavity?

A cavity, also called tooth decay, is a permanently damaged area in the hard surface of your tooth that develops into tiny openings or holes. They are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sugary drinks, and poor oral hygiene.

How Cavities Begin

Cavities don’t appear overnight - they’re the result of a gradual process:
 

• Plaque Formation - After eating, especially sugary or starchy foods, bacteria in your mouth produce acids. These acids combine with food particles and saliva to form a sticky film called plaque that coats your teeth.

• Acid Attack - The acids in plaque slowly wear down tooth enamel, the protective outer layer of your teeth. This demineralization weakens the enamel and leaves it vulnerable.

• Enamel Breakdown - Over time, continued acid exposure causes enamel to break down further, creating small holes in the tooth.

• Deeper Decay - Once the enamel is compromised, the decay can spread into the softer dentin layer beneath, and if left untreated, it may eventually reach the pulp, causing pain and infection.

How to Stop Cavities Before They Start

The good news is that cavities are highly preventable with the right habits and care. Here’s how to keep your teeth strong and healthy:
 

• Brush Twice a Day - Use fluoride toothpaste and brush for at least two minutes, reaching all surfaces of your teeth.

• Floss Daily - Flossing removes plaque and food particles between teeth where brushes can’t reach.

• Limit Sugary Foods and Drinks - Bacteria feed on sugar, producing more cavity-causing acid. Cutting back helps protect your teeth.

• Drink Plenty of Water - Water helps wash away food particles and supports saliva production, which naturally protects your teeth.

• Visit Your Dentist Regularly - Professional cleanings and exams can detect cavities early and stop them from worsening.
