The dentures can be completed in the same day. Our process includes a wax try-in, giving the patient an opportunity to approve the appearance of the dentures before they are processed. This allows the patient to make changes before the dentures are finished. New denture patients sometimes question why the lower denture, generally has less suction, in part, because the lower jaw has worn down faster. The lower denture relies on the patient learning to use their facial muscles and the tongue to assist with the suction of the lower dentures.
