Hi Dr Moore. How can I find out more about using collagen for my receding gum line on the bottom front teeth. Where is this procedure offered and how much does it cost? Since having my third child my gum line has gone and worried I’m going to lose most of my teeth if they get wobbly as I can see the roots of my teeth, is this my only option before I end up with no teeth? How many times has this procedure been done in the Uk? Please help me with this.
