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 will become
All full dentures should have a hard reline every two years. A layer of plastic is removed from the denture‘s interior surface, and then the denture is filled 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.
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.
