As well as making you look better, they can help improve your dental health.
Many people have been put off wearing them because of how they look but modern braces can be very inconspicuous.
One way of making them inconspicuous is by having the brackets - the part that attaches to each tooth - fixed to the back of the tooth.
The brackets can be also be made in many different materials such as metal, ceramic or plastic so they can be more attractive or less visible.
They can also be designed to appear less noticeable - say be being clear or tooth-colored.
You can also choose to have them in virtually any color. You can even have them gold-plated or glowing in the dark.
Some people like to have their braces shaped in as something distinctive such as a heart or a football.
