To try and sum up: Was told to use Corsodyl twice a day to help my gums but wasn't told to use it for only two weeks, and was not told this would seriously stain the back of my teeth - to which I was told that they couldn't remove the stains because they didn't have the right tools. Had to go to another dentist and pay £50 for them to do it. Was not told at the beginning of my invisalign treatment about the number of attachments I would need to have on my teeth, these would stain (I believe the glue stained) even though I must've been brushing my teeth 4 times a day minimum at this point. The dentist who usually wears pink (and is lovely) changed my attachments because she realised they were stained but the other dentist didn't do it the next time, every time I had this dentist I could tell she just wanted me to be out of there. I get they've had a busy day, but so has everyone else in this city. This defeated the whole idea of invisalign, I was very insecure about the colour of my teeth for the whole time. I've since had them off, and my teeth are still stained from the glue, I know it's the glue because one of my teeth, that had no attachment on it, isn't as stained. Unlike many other dental practices, finest dental do not offer free whitening at the end of the treatment, even though I was fairly sure that it should've come with that anyway. I have been told 3 times someone would 'get back to me' on that, no one has, one time the girl didn't even ask for my name so I don't know how she thought she was going to manage that. Appointments are literally always running late which I realise is probably not to the fault of the staff but there should be better planning, like booking people in for a bit longer to avoid this. There is also a ridiculous waiting period for appointments, at the end of the treatment I probably could've done with an extra tray but I was so annoyed and tired at the whole process that I just wanted them out so I didn't have to go back anymore. At the beginning of my treatment there were also a number of miscommunications. When my invisalign initially arrived no one even called me or messaged me to say, I had to call and they'd been there for 3 weeks. I tried to change my appointment once and emailed someone to do it, they never emailed me back but had changed my appointment... more guessing games. There's probably a lot more, I sent an email of complaint a couple months into my treatment, which didn't get responded to for an age. I eventually had to email the girl who initially set everything up for me (as she was the only useful person/person I could actually get through to) who had to look into it for me, and I'm guessing remind whoever it was to reply to me, which had obviously been ignored. Don't get me wrong, my top teeth are straight now. Which I guess is what I wanted. But when you're forking out this much money you expect a bit more in terms of customer service and organisation. I would've much rather gone somewhere else, I expect I wouldn't have been overly stressed and really not looking forward to going to the dentist every time I had an appointment, and would probably have white teeth to. Very average for the price you are paying.
