“Can dentures be done in one day?”

I don't recommend it!

Sometimes.

The most common technique to get dentures "done in one day" is to do an immediate denture, where a denture is fabricated prior to removing teeth, and placed on the same day that teeth are removed. Immediate dentures (sometimes called "healing dentures") will loosen as your body heals, and are usually either replaced with another denture, or are relined to fit your mouth as your body heals. An immediate denture appointment usually involves several steps, and several appointments prior to the surgical date.

Over the past 10 years, there have been many innovations in immediate denture fabrication. However the final result is very much dependent on both the condition of the patient's mouth going into the procedure, the patient's healing ability, as well as the skill of the dentists and laboratory technicians involved.

Dentures can be done in a day, however, most times there are steps that have to be done before the denture process is complete.

Immediate dentures can be placed right after teeth extractions. They need to be adjusted and in most cases redone a few months after. 

Dentures can be placed immediately after teeth have been removed. You can even have implants and implant dentures placed in one day. However, the fabrication of dentures takes some time and a few steps and can normally not be accomplished on one day - so before the one day dentures there will be a few appointments and some time for the lab do fabricate them.

Immediate dentures (placed right after extractions) given to patients same day teeth come out, but these tend to be more costly than conventional dentures (dentures made after healing) or interim/transitional dentures (denture worn while healing only or 2nd set if conventionals need to go out to lab for repair) . Immediate dentures need several soft relines for up to 6 months performed by the dentist as the patient heals and tissue shrinks. After 3 to 6 months the dentist may say you can get a permanent reline because the tissue and bone has completely healed. Sometimes immediates or transitional/interm dentures are not as esthetic as conventional because the lab has to guess where your tissue is going to end up after the teeth are extracted. An interim or transitional denture is worn while you are waiting to heal and is also placed immediately after surgey, however it is typically made from cheaper products because it is only ment to last while healing. The teeth typically wear faster than conventional dentures but the teeth last just fine while healing with an interim/transitional denture. With transitional dentures the lab has to guess where your tissue will end up and may not be a perfect result. If you choose an interim and conventional denture you will have 2 sets so if something happens to your conventional denture you can send it out for repair and still have a set you can wear while you wait for them to come back. Insurance usually will not cover an interim/transitional denture but they are highly recommended.
