What's the Difference Between Dental Crowns and Dental Bridges?

From Colgate.com:

"A dental crown can cap an individual's damaged or decaying tooth or be placed on top of a dental implant to replace a missing tooth. Dental implants are metal fixtures, surgically fastened to your jawbone below the gums. These metal implants become anchored to your bone through osseointegration (the bone fuses to the metal). This process provides stable support you can rely on while eating and speaking. According to the Cleveland Clinic, the healing process after getting an implant can take 6-12 weeks. Your dental professional will then place a metal post (or abutment) into your implant, onto which they will mount your crown.

Bridges, on the other hand, are solely used to replace missing teeth. They have two crowns – one on either end – and a bridge of replacement teeth that rest in the area of the gums where there is tooth loss. The crowns at the ends of a bridge can fuse to existing teeth (that need to be filed down by a dental professional to fit correctly), or your dental professional can attach them to dental implants.

Whichever of these replacement tooth options is best for you – they can be vital in maintaining your oral health. Gaps in areas of loss can cause your other teeth to begin rotating or shifting into the empty spaces, resulting in a bad bite. And missing teeth can even lead to gum disease and temporomandibular joint (TMJ) disorders."
