Q. Good morning, I have a 5mm diastema between my upper two front teeth, my dentist advised that i have a crown put in, however I dont want to have that done because it will look as though i have three front teeth, how long will i need to wear braces for, I am 26 years old and I had a frenectomy done when i was in primary school, will porcelain veneers be my best option even if i have to leave a 1mm gap, just as long as it will look better than it does now.,
