The difference between lingual braces and traditional braces is that they sit behind your teeth so that nobody will see them unless you want them to
yes Miley Cyrus does have braces behind her teeth
An orthodontist can put braces on your teeth
Yes I never had braces but just be careful when you're kissing cause you can cut your lips ( the inside ) or the other kisser's lips.
No. The braces will hold the teeth in place.
Braces are things that go on your teeth and it straighten your teeth and make you have a nicer smile
Yes, she does! But she has them behind her teeth. She got them last July. Actually you need them in front to fix you teeth because if there in back it wont fix your teeth actually your wrong so um i felt like telling you that in back braces do help if you had seen my smile you would know No, she might of had a retainer, but no braces. [EDIT: Miley Cyrus had braces on the back of her teeth, so that viewers couldn't see her braces. That's why she had a "lisp" sometimes]
Of course you can. Braces have nothing to do with the "color/brightness" of your teeth. Braces are used to straighten teeth. If it is, in your finding, that drinking coffee has discolored your teeth, then he or she (your dentist) can apply a "whitener" to your teeth, regardless of braces. Regards
yes you have to have braces on if your teeth are bad or less your teeth will move alone and your mouth will be weird
Braces are often used to remove gaps in teeth.
You can get braces for any type of teeth that you may have. A dentist will be able to let you know if you are able to get braces.
yes because the braces would straigten your teeth still
