Enamel can repair itself by using minerals from saliva, and fluoride from toothpaste or other sources. But if the tooth decay process continues, more minerals are lost. Over time, the enamel is weakened and destroyed, forming a cavity. A cavity is permanent damage that a dentist has to repair with a filling.

Can you restore tooth enamel?

Once tooth enamel is damaged, it cannot be brought back. However, weakened enamel can be restored to some degree by improving its mineral content. Although toothpastes and mouthwashes can never “rebuild” teeth, they can contribute to this remineralization process.

How long does it take for enamel to repair?

The remineralization process usually takes about three to four months to take effect. However, once you begin to better fortify your enamel, you may start to see stronger teeth, experience less sensitivity, and even reveal a whiter smile.
