How Long Does It Take To Go Through Dental School Plus Specialty In Orthodontics?

Here in UK -
5 years minimum at dental school. Then a further 2 years doing general professional training. (1 year practice, 6 months community and 6 months hospital). After that you need a further 2-3 years to do SpR training. You can then apply for your CSST and call yourself a consultant. If you simply wish to be a specialist practitioner, you can do that straight away although you should really do a lot of courses before then.

Anyone Who’s Gone Through Invisalign?

I went to the orthodontist to talk about straightening my teeth. I am not in my teens so I didn’t really want braces. He said that Invisalign would work great for me. He said that it’d take about a year to completely straighten both top and bottom(at first I was only planning on doing the top teeth, but while they’re at it, they can take care of the bottom as well.) And the cost is about $3000.
For those who’ve had Invisalign or are going through it, how is it? Painful? Are those trays a real pain in the butt to manage? Can people notice you’ve got them in? Can you drink water with them in?(I’m constantly drinking water throughout the day)
