The biggest benefit of dental implants is that almost everyone is a good candidate. If you are an adult who is missing one or more teeth and is in good general health, then you’re an ideal candidate for dental implants.

In this article, we’re going to talk about dental implants, specifically All-on-4 implants, reasons why you may not be a good candidate for them, and your available options should you not qualify.
