Denture relines are a necessary part of maintaining a healthy mouth.
Most people that have dentures are aware that as time goes on gums tend to shrink. Think of how much your face changes over a period of five years, the inside of our mouths also changes over time. As the Jaws change, the hard plastic does not change, and often the result of this is being a small space between the denture and the gums. This space is often too small to notice with the naked eye but is enough to cause discomfort, sore spots, and even brake the seal that holds the denture in place. A denture reline can be thought of as the process of filling this space or updating the fit of the denture.
