Hi there,
Actually i use traditional braces but for finishing my treatment I was thinking to do it with inivisalin.
It's recomended to do it? Do they hurt?
Both braces have it's own merits. Many people consider invisalign braces as they are invisible and is more comfortable.
But invisalign braces is not recommended for correcting all types of malocclusions.
I wouldn't say less painful at all. I would say similar. Girlfriend just started invisalign and her teeth hurt just as much as regular braces and the attachments are doing a number on her lips and cheeks as well (although with the trays in she doesn't have this issue, just when eating or drinking)
