Tooth-straightening technique ‘without the metal-mouth’
Heavy metal braces and bands have been updated with a newer, more attractive form of teeth-straightening techniques, reports the New York Post.
Invisalign, approved by the Food and Drug Administration in America uses 3D technology to create customised aligners from impressions of the patients teeth.
No drilling is involved and the results of the six-month process are completely invisible, reports the newspaper. The patients can also eat anything they want, unlike traditional braces which ban sweets and chewing gum.
"This treatment even allows you to whiten your teeth while they straighten," claims Dr Bruce Blau, a Manhattan-based cosmetic dentist.
Leaving crooked teeth untreated can lead to sleep disorder, gum disease and increased wrinkles in the face, he added.
However, the newspaper claims the process can be slow and the aligners must be removed before every meal and the teeth must be cleaned before reinserting them.
One in five people closetheir mouth to conceal their teeth when posing for photographs, according to a survey by Mintel for the British Academy of Cosmetic Dentistry.
