Only a dentist—preferably one experienced in dental prosthetics—can help you determine your best tooth replacement option and help you decide if dentures are right for you. Dentures are typically best for: Replacing all of the teeth in the lower and/or upper arches Replacing an entire mouth of teeth Replacing several adjacent teeth Conventional dentures are usually recommended for people who: Do not want to undergo the process of dental implants Do not have the overall health or bone density to support dental implants Prefer a removable option for their tooth replacement Implant-supported dentures can be good for people who want a semi-permanent to a permanent solution for tooth replacement and who have the jaw density and health to support implants.
