I have to have my front right tooth removed due to 3 failed root canals and a chronic underlying infection. Since I am forced to do dental work I would like to improve whatever I can at the same time. Should I get a single dental implant or a fixed bridge which would include my front four teeth. He says he can correct the bit of protrusion my teeth have and improve on the alignment with bridge but the implant is less invasive. I want the best overall look.
