I've had Invisalign for 7 weeks but still on tray 5 as I keep getting the "do not proceed" message from dental monitoring as my teeth aren't moving as fast as they'd like. It hurts, my mouth is full of ulcers from the elastic band buttons, I keep losing attachments, I can't snack ever, the tooth brushing is a constant drag and all in all I'm wondering why I've done this to myself (and paid £4k for the privilege!). Can anyone give me their happy ending and tell me it gets better...? I have 46 trays which at this rate will last about 15 months. I'd never give up but I could do with lifting out of my first world problem self-pity right now...
