I would like to have my teeth extracted and dentures placed immediately. What are the advantages and disadvantages of doing it this way?

The most obvious advantage to having the denture placed the day of extractions is the fact that you will not have to go without teeth. You will also find that an immediate / temporary denture will act similar to a bandage over your gums, helping to control bleeding and swelling following extractions.

The major disadvantage of an immediate denture is the fit. The denture must be fabricated before your natural teeth are extracted, therefore the accuracy of the fit is reduced. It also does not allow to try out your denture to verify the appearance.

Often the treatment of choice is a temporary / immediate denture, worn while the gums resorb, followed by a permanent denture six to twelve months later.
