In most cases, the gums need time to heal before dentures can be fitted. Typically, healing takes between 4 and 8 weeks, although it varies from person to person. During this time, the gums and jawbone change shape and size. Waiting for proper healing ensures a more accurate fit and optimal comfort. Once the gums have healed sufficiently, the dentist will take impressions of the mouth to create custom dentures. In some cases, immediate dentures are placed right after the remaining teeth are extracted. These immediate dentures serve as a temporary solution while the gums heal.
