More than half of all Americans have now had braces on their teeth, but few have ever actually seen the process occur quickly.

Thanks to this time lapse video, we can see the normally years-long teeth straightening ordeal in just one minute.

According to the American Dental Association, braces aren’t just for aesthetics, they can have real health benefits:

Braces and orthodontic treatment are used to correct “bad bites,” or malocclusion (teeth that are crowded or crooked). In some cases your teeth may be straight, but your upper and lower jaws may not meet properly. These jaw or tooth alignment problems may be inherited or could result from injury, early or late tooth loss, or thumbsucking.

If you have an abnormal bite your dentist may recommend braces or another orthodontic treatment to straighten out your smile. Correcting the problem can create a nice-looking smile, but more importantly, orthodontic treatment results in a healthier mouth. Not correcting an abnormal bite could result in further oral health problems, including:

tooth decay
gum disease
tooth loss
affected speech and/or chewing
abnormal wear to tooth enamel
jaw problems
