Cavities remain one of the most common chronic diseases in the world. According to the World Health Organization, oral diseases affect billions of people, with cavities in permanent teeth being the most common form. Experts explain why enamel destruction begins, what factors increase the risk, and what early signs can help detect the problem before pain occurs.
What Happens to a Tooth with Cavities
Cavities are the gradual destruction of the hard tissues of a tooth due to the action of acids. These acids form when plaque bacteria metabolize sugars and simple carbohydrates from food. Initially, the enamel—the hardest layer of the tooth—suffers. At this stage, the changes can be reversible. If the process is not stopped, the damage progresses to the dentin and can reach the pulp, causing inflammation and severe pain.
Experts from the FDI World Dental Federation emphasize that cavities do not develop suddenly but as a result of a combination of several factors—microbial plaque, frequency of sugar consumption, and inadequate hygiene.
Main Causes of Cavities Development
1. Accumulation of Plaque
A bacterial biofilm forms daily. If it is not removed with a toothbrush and floss, microorganisms begin to actively produce acids.
2. Frequent Sugar Consumption
It is not so much the amount of sweets that is dangerous, but the frequency of their intake. Constant snacking maintains an acidic environment in the mouth, accelerating the demineralization of enamel.
3. Sweet and Acidic Beverages
Soda, packaged juices, and energy drinks combine high sugar and acid content, exacerbating the destruction of the tooth surface.
4. Inadequate Hygiene
Infrequent or improper tooth brushing, refusal to use dental floss and irrigators lead to plaque accumulation in the interdental spaces and on chewing surfaces.
5. Reduced Saliva Production
Saliva neutralizes acids and helps restore enamel. When the mouth is dry (for example, due to medication or dehydration), the protective mechanism weakens.
6. Crowding of Teeth and Orthodontic Appliances
Braces, retainers, and closely spaced teeth complicate hygiene, creating risk zones.
7. Lack of Regular Check-ups
A preventive visit to the dentist every 6 months allows for the detection of cavities at the stain stage, when treatment is minimally invasive.
How to Recognize Cavities at an Early Stage
At the initial stage, the disease may progress without pain. However, there are signs that should not be ignored:
-
White or chalky spots on the enamel—signals of initial demineralization.
-
Increased sensitivity to cold, hot, or sweet.
-
Darkening of fissures (natural grooves in molars).
-
Roughness of the tooth surface felt by the tongue.
-
Discomfort when biting down without an obvious cause.
If cavities progress, noticeable darkening, a cavity in the tooth, and pain, especially with temperature or pressure, appear.
Can the Process Be Stopped?
At the white spot stage, the demineralization process is still reversible. Remineralizing gels, fluoride-containing products, and professional hygiene are used. However, when a cavity forms, treatment and tissue restoration are required.
Experts emphasize that prevention is more effective than treatment. Reducing sugar consumption, daily hygiene twice a day, using dental floss, and regular check-ups significantly reduce the risk of developing the disease.
...Cavities are not a sudden problem but the result of gradual changes. Their early signs often go unnoticed until pain arises. Paying attention to the condition of enamel, monitoring diet, and regular visits to the dentist allow for the detection of the disease at an early stage and the preservation of dental health for many years.
