Fluoride is added to toothpaste primarily to help prevent tooth decay and strengthen tooth enamel.
Here's a more detailed explanation:
-
Prevents Tooth Decay: Fluoride makes tooth enamel more resistant to acid attacks caused by bacteria and sugars in the mouth. These acid attacks are the primary cause of cavities.
-
Strengthens Enamel: It incorporates into the enamel structure, forming fluorapatite, a more stable and acid-resistant mineral than the original hydroxyapatite.
-
Reverses Early Decay: Fluoride can help reverse early signs of tooth decay by remineralizing weakened areas of enamel.
-
Mechanism of Action: When fluoride comes into contact with teeth, it promotes the deposition of calcium and phosphate ions, which rebuild and strengthen the enamel. This process is called remineralization.
Many popular toothpaste brands, such as Sensodyne, include fluoride to offer these benefits. Regular use of fluoride toothpaste, combined with proper brushing habits, is an effective way to maintain good oral hygiene and protect your teeth from decay.
