remineralisaatiossa

Remineralisaatio is a natural process that strengthens tooth enamel. It occurs when minerals, primarily calcium and phosphate ions, are deposited back into the enamel surface. This process is crucial for repairing microscopic damage that constantly occurs on teeth due to the acidic environment created by bacteria in the mouth. These acids, produced after consuming sugars and starches, can demineralize the enamel, making it weaker and more susceptible to cavities.

Saliva plays a vital role in remineralisation. It contains dissolved calcium and phosphate ions, as well as fluoride if it's present in toothpaste or water. When saliva flows over the teeth, it can replenish the lost minerals, effectively reversing the early stages of enamel erosion. This process is most effective when the pH in the mouth is neutral or slightly alkaline.

Fluoride significantly enhances remineralisation. It integrates into the enamel structure, forming fluorapatite, which is more resistant to acid attacks than hydroxyapatite, the natural mineral in enamel. This makes teeth stronger and less prone to decay. Therefore, using fluoride toothpaste and consuming fluoridated water are common strategies to promote remineralisation and prevent cavities. Factors like good oral hygiene, a balanced diet low in sugars, and regular dental check-ups also support this natural repair mechanism.
