Can I get a fake tooth instead of braces? (Photo)

i have one (probably two, one on either side of my 2 front teeth but one bothers me more than the other) tooth thats really twisted. i was wondering if i could get the tooth replaced instead of getting braces because they take so long and its only one tooth, would the tooth actually look fake compared to the rest? would it fall out easier? plus i know this is silly but im 18 and about to go to uni and i dont want to have braces plus they are really expensive. any suggestions would be appreciated
