Stages before a tooth decays

Before a tooth fully decays and forms a cavity, several stages occur due to the interaction of bacteria, food, and tooth enamel:

• Plaque formation: Bacteria in the mouth mix with food particles and saliva to form a sticky film called plaque on the tooth surface.
• Acid production: When you consume sugary or starchy foods, the bacteria in the plaque feed on these carbohydrates and produce acids as a byproduct.
• Enamel demineralization: These acids attack the tooth's outer protective layer, the enamel. They dissolve the minerals (like calcium and phosphate) from the enamel, a process called demineralization. This often appears as white spots on the tooth surface, indicating the initial weakening of the enamel. If this process continues without intervention, it eventually leads to a cavity.
