Q. I recently have finished my treatment with invisalign with a clinic in harley street. Yet, me teeth are still protruding from the front.Although,the arch in my mouth is now aligned. I expected my front two teeth to be pushed in completely. I now have been told that I will have to have 4 teeth taken out and fixed braces for 18 months for them to be pushed in. Are there any other options which can be taken as this treatment is very long?
