All smiles with dental implants? What to know before getting them

You need much bigger teeth to sustain you as an adult, so everyone gets a second set.
If you've been told you're not a candidate for dental implants, it's time to revisit the subject. Dental implants — permanent prosthetics implanted into the jaw — have changed.
"In the last five years, we've learned that smaller implants can work just as well as regular-size implants, and this makes more people candidates for them," says Dr. German Gallucci, department chair of restorative dentistry at the Harvard School of Dental Medicine.
What is a regular-size implant?
A conventional dental implant is a post that serves as an artificial tooth root. The post is made of titanium and is surgically implanted into the jawbone, below the gum line. As the jaw heals, bone grows over the surface of the post, strengthening its position.
