Q. Good afternoon, I have a small gap in the front of my middle top set of teeth and as I am an adult I do not want to have metal brace that is clearly visible. I am interested in other methods such as invasilign and inman aligners. Please can you let me know what would be the best option. Also can you let me know if these proceedures are proven and trustworthy. Also can you suggest what I should be looking for when researching a particular dentist. Thank you for your help. Regards Lucy,
