If you have dentures, then you should know that certain denture services will need to be completed on a regular basis. These services are likely to include relining, so keep reading to learn what this is and how you can tell that one is required.

What Is A Denture Relining?

A denture relining is simply the replacement or reshaping of the base of the denture. This base is the acrylic one that sits next to the gum tissues that rest on the upper and lower arches. The arch is supposed to sit snugly on the gums, but the tissues and the jaw bone will shrink over time. This happens naturally as you age, especially since the teeth are no longer stimulating new bone growth.

So, when the shrinkage occurs, the dentures will not fit tightly any longer. To ensure proper fit, your dentist will add new material to the underside of each denture so they mold firmly to the arches again. 

There are two types of relining techniques that are referred to as soft and hard relines. The soft variety utilizes a polymer material that is poured directly into the denture to create a soft cushioning layer. This layering technique can often be done chairside with adjustments made immediately to ensure fit. 

Hard relining can be scheduled too and is often completed in a laboratory facility. This is where a hard acrylic is either added to the base of the denture or the base is partially replaced. Hard relines tend to last longer than soft ones, but you will be without your dentures for some time. So, you should have an extra denture set if you want this sort of reline procedure.

When Is A Reline Needed?

There are a few signs that you should watch out for that indicate that a denture reline is necessary. The most obvious is the fact that the dentures seem much more loose than they used to be. And, you are probably using a great deal more denture cream than you should just to keep your dentures in place.

You may notice sores building on the gum tissues due to friction and movement as well and you may not be able to eat as well as you used to. If there are big spaces between the dentures and the gums, then you may see food building underneath the dentures. 

Also, a relining may be necessary if you have not had one completed within the last two years. It is best to schedule a relining within this timeframe to ensure optimal fit.
