Immediate dentures are made in advance and can be placed in the gums as soon as the teeth are removed. They generally should only be considered a temporary solution until conventional dentures can be made.
Advantage: The wearer does not have to be without teeth during the healing period.
Disadvantages: More adjustments are required to fit the dentures properly during the healing process. They will need to be adjusted periodically until they are comfortable. Also as healing progresses, the gums and underlying bone will smooth out and shrink. The immediate denture may then need to be relined or rebased to restore a close and comfortable fit.
