The Instasmile Customer Services Team, have been, Professional, understanding and supportive throughout. I needed a smaller tray, (my own dentist had to shave the ends off), and one was provided. I did need to transfer putty over. The Impressions were accepted after a couple of tries. It’s worth persevering as you receive an Instasmile that matches with your own teeth. My Instasmile arrived about two weeks. I really like it, and Friends and Family say it looks natural. I went for top and lower in A1, which are perfect, not too blingy but natural white. I got the Classics as I wanted to try Instasmile. I’ve not had them long enough to determine if I would eat with them, although the Card you receive suggests you can. I think you just have to be sensible, and build up and try different foods - that’s what I shall be doing. I will likely go for implants in the future, but wish to hold on to the teeth I have. I have lost a few teeth, and my Instasmile covers those gaps. One of the teeth lost is a front one, and I awaiting a Denture. I feel the Denture will feel alien in the roof of my mouth, whereas the Instasmile feels very smooth, and importantly the roof of my mouth is untouched. I do have a slight lisp, but I’m sure that will go in time, the more I use the Instasmile. I was pushing Air out of the front tooth gap anyway, so spoke differently. My confidence is back and I’m smiling once more, which is really great.
