Relines of dentures should improve the fit of the base of the denture to the jaw. However, if your jaw has been without natural teeth for some time, it may be difficult to make the denture stable if there is little jawbone. Soft tissues beneath dentures can also become easily irritated by wearing dentures continually (24 hours a day). You should refrain from wearing dentures at night as this gives the skin a chance to recover from wearing them during the day. Your denturist should make sure that the skin inside the mouth is healthy and take steps to treat it properly before relining. If there is enough jawbone available, relines can often be done well. If not, it may be necessary to revisit the need for either remaking or redesigning the denture.
