Complete dentures replace full set of teeth from upper and lower jaws of the dentition. They can aid in chewing and biting functions. Dentures can be directly fixed over gums or can be supported by implants. Complete dentures are one of the oldest methods of replacing lost teeth. There are two types of complete dentures, namely conventional and immediate dentures. With immediate dentures dentists can restore teeth in just one visit. The conventional type of dentures has a healing period of few weeks during which the gums shrink. The patient should visit the dentist the second time to get his dentures adjusted after the gums shrink.
