Dental implants are especially likely to fail in people who have unhealthy gums. Because smoking is bad for the health of your gums, it increases the risk that a dental implant won't work.

If you ever lose a tooth -- perhaps in an accident -- your dentist may recommend that you get a dental implant to replace it. A dental implant is a very modern, high-tech way to replace a missing tooth. When you get an implant, the dentist places a metal post into the bone under the gums. After the bone heals, a replacement tooth is attached to the post. Unlike other kinds of replacement teeth, implants look and feel like the real thing.
