Decalcification is a problem that can occur with poor oral  hygiene during your orthodontic treatment.    Without good oral hygiene food  and plaque can be trapped in and around your braces.  This bacteria  plaque reacts with the sugars and starches in food and forms an acid that can eat away the enamel on your teeth, permanently marking your teeth.

If you allow plaque to accumulate around your braces, it can leave permanent marks on your teeth when your braces are removed.  This can cause damage called decalcification. These lines and spots will remain on your teeth for life.

Teeth with decalcification scars do not look as nice as healthy teeth. It is difficult and expensive to have your dentist restore decalcified teeth so they look nice again.
