Hi everyone,
I want to start by saying I am only in my early 20s, I live in London, I am trying to save up for a deposit on my first home and really really hate my smile to the point where I do not smile in pics or like meeting new people in case they stare. I have a gap in my teeth and apart from that they’re pretty much straight
Anyway so this morning I went to the orthodontist for an Invisalign consultation. I was looking online for ages that the treatment will be around the 3000-4000 mark which I was sort of ok with. Turns out I have really bad enamel loss at the back of my teeth on quite a lot of my teeth. I have been struggling really bad with GERD (acid reflux disease) causing me to vomit quite a lot of the time. I was also pregnant couple years ago with really bad morning sickness I was vomiting everyday, sometimes a few times In the day for maybe about 2/3 months. So when I was told I have slight tooth decay I kind of expected it. Now… she says that the Invisalign itself is about £3800 but the fillings for all the teeth is bringing the cost TO £6000!!!!! 
I left the dentist feeling so low to be honest, beginning to second guess if it’s really worth it. I feel like I’m being mugged off though which is why I’m putting this up. I don’t know if an extra £3000 on fillings is actually reasonable or not. Like I said I do live in London (not even central which is the crazy thing) and I think that this dentist is supposed to be quite popular. Should I look elsewhere? I did pay £100 for an x-ray next week so she can give me more of an accurate price and maybe give me a more solid idea.
I need help if I should go ahead with the plan!!
