New dentures will typically fit your mouth very securely as it has been designed specifically for your gums. As time goes on, your gum tissues will change and the fit of the denture may become loose and more prone to movement. Having the denture professionally relined every couple of years will keep the denture secure and functional.
Hard Denture Reline
A hard reline removes a layer of plastic from the dentures interior surface, and then fills the denture with a putty-like material which conforms to the contours of your mouth creating an accurate impression. The denture is sent to the lab where it is adjusted to the new shape of your gum tissue. This results in maximum contact between the denture and your mouth.
Soft Denture Reline
Some patients are unable to wear ordinary dentures because of tender gums or sore spots. Relining the denture with a material that stays pliable for one to two years before needing replacement. This material is much less likely to give the patient sore spots than the standard hard reline acrylic. Patients experiencing these problems may also consider a more permanent solution of implant retained dentures.
