You might not be able to use invisiline because you have missing teeth. Invisiline might not be strong enough. But you can have a free consultant from doctors and they will answer all your questions.
I started mine when I was 36 and had ceramic braces on for 2 years and 7 months. I had 4 teeth pulled out when I had my braces and was not qualified for invisiline (of course I am not sure if this is the only reason that I was not qualified. That was three years ago. They may have more advanced invisiline technology now). I don't see any 'side effect' afterwards. Love the results. I definitely smile more now. Show off my perfect teeth. HAHAHA
