Cariogenic foods

Cariogenic foods are those that, once ingested, promote the formation of acids in the mouth. What does this mean? It means that indirectly, these are foods that create an ideal environment for the development of dental cavities.

The presence of sugars in certain foods leads to a drop in oral pH after each meal. In this way, dental plaque comes into contact with these sugars, metabolizes them, and releases acids that act on the destruction of tooth enamel, leading to the formation of holes or cavities, commonly known as cavities. This is the process by which cariogenic foods end up having a direct relationship with the erosion of dental tissue.


To prevent the potential occurrence of dental cavities, it is important to know which cariogenic foods pose a greater threat to oral health. Sugar is the first thing that comes to mind. Although it is not a direct cause, it does create the ideal environment for cavities to develop.


List of cariogenic foods

  • Carbonated beverages: Due to their liquid composition, they penetrate the interdental spaces, which are high-risk areas for cavities. Additionally, they affect tooth enamel, weakening the teeth over time.

  • Sweets and candies: These are highly adhesive to the teeth and are often consumed between meals, posing a problem. It is better to choose those that are lighter and easily disappear from the mouth.

  • Acids and citrus: Excessive consumption of acidic juices like lemon, orange, or grapefruit should also be controlled. The consumption of tomato sauce (ketchup), which contains sugar and acetic acid, and wine, which can stain the teeth and reduce saliva flow, should also be monitored.

It is important to always maintain good dental hygiene, brush your teeth between meals, and use dental floss and mouthwash regularly. Additionally, you should visit your dentist periodically. If you experience any symptoms of a possible cavity, do not hesitate to contact Dr.|A® Dentistry. Catching cavities early can prevent complications in your mouth.
