New dentures will typically fit your mouth very well as it has been designed specifically for your gums. As time goes on, the underlying bone that supports your gum tissues will change (shrink) and the fit of the denture will become more loose and thus more prone to movement inside your mouth. This “shrinking” of your gums is really resorption of the alveolar bone that use to support the teeth. The body is aware that the teeth are gone and begins to remodel and take the bone away slowly over time.
All full dentures should have a hard reline every two years. South Texas Dental Implants & Prosthodontics 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.
Some patients are unable to wear ordinary dentures because of tender gums or sore spots. South Texas Dental Implants & Prosthodontics may recommend 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.
If dentures have not been serviced in quite some time, a patient’s gums may be red, swollen, or misshapen. This creates problems in taking impressions for a new hard or soft reline and may lead to a denture that would perpetuate the problem.
A temporary, or palliative (medicated) reline material may be recommended to allow the inflammation to subside. This reline makes the denture fit much more tightly, and is usually soft and pliable. After a few weeks, the gums return to a more normal state. The patient is then ready for his new denture or hard reline.
