Here in Canada we are experts at replacing front teeth, we see so many hockey fights gone wrong.Likely you need the bone built up in the ares of the loss, then implants are placed. Depending on the space and the philosophy of the doctor, 1 or 2 implants can be used to support 2 teeth.Go see some doctors and look at their before and after pictures. Make sure you ask for pictures where you can see the gums. Most before and afters in implant dentistry show the smile only, tells you nothing about the surgical work. You need to see what the gum to tooth interface looks like. Is the color of the gum , the height of the gum, the consistency of the gum same as the other teeth? Do you see dark lines? These are the important things to evaluate before choosing your doctor.Good Luck.
