Teeth normally fit tightly against one
another. Spacers are inserted before placement of your
braces to provide some space between teeth for attaching the
bands. There are two types of spacers, small springs or
plastic modules. In just a few days they gently move desired
teeth slightly apart.
Spacers often cause some soreness, but this
goes away in a few days. Rinse your mouth with warm salt water to
relieve the irritation. Your normal chewing also helps to get your
mouth feeling better.
