When a person has new dentures, they are custom made, according to the shape of his mouth, to assure proper fit and retention. Usually, a set of dentures will last up to seven years. However, due to the changes in shape of the mouth, and normal wear and tear of denture, a relining is usually necessary.
What Relining Is
*
Denture relining is a procedure that involves shaving away the underside of dentures and replacing with plastic, to assure proper fitting to the gums. Bone loss in the mouth area is often cause for the need of this procedure, as well as prolonged use of the dentures. Relining procedures can be done either in a dental office, or in a veneer laboratory.
Relining Procedures
*
There are three kinds of denture relining procedures, each one for specific needs. A hard reline is recommended by dental professionals as a procedure that needs to be done as frequently as every two or three years. A hard reline cannot be done during a dental visit, and is sent to a laboratory for accuracy. A soft reline is for patients with sensitive gums who develop painful spots from the underside of their dentures. To remedy this, dental professionals line the denture with soft material that requires frequent relining. Temporary relines are also available to people who have worn their dentures so long, that their gums become swollen, and even misshapen. Temporary relines usually contain anesthetic to subside the swelling, before proper dentures can be fitted.
