Remineralisation

Remineralisation is a natural process that repairs damage in the tooth enamel layer by using minerals, such as calcium and phosphate, present in saliva and some foods. This process can be enhanced by the use of fluoride, which is often added to toothpaste and drinking water in many countries.

Process of Remineralisation[edit | edit source]

Remineralisation begins in the oral cavity. When the pH level in the mouth drops below 5.5, the demineralisation process begins, which can lead to tooth decay. However, when the pH level rises again, remineralisation can occur. The minerals in the saliva, such as calcium, phosphate, and fluoride, can then be absorbed by the tooth enamel, repairing the damage caused by demineralisation.

Role of Fluoride[edit | edit source]

Fluoride plays a crucial role in the remineralisation process. It is absorbed by the tooth enamel and forms a new layer of hydroxyapatite, which is more resistant to acid than the original tooth enamel. This can help to prevent further tooth decay and maintain oral health.

Importance of Diet[edit | edit source]

A diet rich in minerals, such as calcium and phosphate, can also aid in the remineralisation process. Foods such as milk, cheese, and other dairy products, as well as leafy green vegetables, can provide these necessary minerals.
