Why should I use a fluoride mouthwash during brace treatment?

The outer layer of your teeth is called enamel and is made mostly from tightly-packed crystals called “hydroxyapatite”. Tooth decay occurs when plaque acid from bacteria dissolves the crystals away.

In orthodontic treatment, there is a risk of “demineralisation”  due to the same process. This appears as permanent white or brown marks on the teeth.

Fluoride works by altering these crystals to “fluorapatite” which makes enamel much more resistant to acid attack.

Daily fluoride mouthwash during orthodontic treatment is one of the ways you can keep lots of strong fluorapatite crystals in your enamel.

And that’s why dentists recommend you should use a fluoride toothpaste.
