Now it's easy to lenghten your teeth

Orthodontists now are offering to lengthen your teeth and that improve the way you look, especially when you smile.
"Every decade over the age of 30," US dentist Dan Deutsch says, "you show a millimeter less of your front teeth." Everything starts to sag a little, and the elasticity in the skin around the lips isn't what it used to be. So, as gravity pulls its weight, more of the bottom teeth show.But there's a way to reverse — or at least slow down — the inevitable."

Orthodontist Garrett Djeu explains there are tiny fibers that connect teeth to bone in the mouth."Those fibers tend to pull the teeth back to where they came from" Djeu says, "so that's why you commonly get relapse."

To solve the problem, one company has popularized invisible braces called Invisalign. The technology involves using a sequence of transparent, plastic molds that are worn like retainers.
"Invisalign works very well in certain types of cases," Djeu says. But it's not for buck teeth, overbites or crossbites. Djeu found that Invisalign is good at closing small gaps and correcting mildly crowded teeth.

The cost of veneers can also run a couple thousand per tooth. Invisible braces range from about $2,000 to $6,000.
