I got my insta smile top teeth (only needed top teeth) about 8 years ago and they are still going strong!! I even had an issue with them when I first got them and customer service was excellent, they sent me a new product right away no questions asked. I wear them every day and will not go anywhere without them!! They are a life changer for me. I could smile again and talk to people without putting my hand in front of my mouth. People have no idea that I have missing teeth. I don’t know why there are so many negative reviews because I absolutely love mine!! My whole life changed and my confidence level is so much better!! I work with the public and was so embarrassed about my missing teeth. Thank you insta smile for making my life better!! (Hugs)
