Trends come and go. Some are harmless and some are extremely dangerous. Well the newest trend that is sweeping across the country has Orthodontists worried.

Now we all know that having braces are expensive. They can easily cost up to $5,000, which is a lot for many families — especially ones with multiple kids. So, some teens are trying to straighten their teeth themselves, making DIY braces out of Goody hair elastics.

The increasingly-popular ‘gap band’ trend sees young people tying small, cheap hair elastics around their teeth in an effort to close the gaps between them.

Dental experts have issued severe warnings about a growing trend saying the procedure could cause permanent damage to their gums and even result in their teeth falling out.
