A dental implant literally replaces a missing tooth. A dental implant replaces the root of a tooth in the jaw bone, to which the cosmetic dentist attaches a cosmetic tooth. A dental bridge, on the other hand, is non-surgical and uses the adjacent teeth to support a new cosmetic tooth. A dental implant is NOT invasive to surrounding teeth (especially desirable if they are healthy and in good condition). By simulating the root, it engages the bone and keeps it healthy. Because a dental implant is an individual tooth it is also easier to floss.
A dental bridge maybe a good choice if the adjacent teeth are in need of restoration. However, there are other subtle factors such as age, timing and bone health that you should discuss with Dr. Adler when deciding which option may be suitable.
