Putting The "Re" In "Denture Repair": Relining Versus Rebasing

Dentist Blog

Most dentures require some type of repair or adjustment periodically. This is completely normal, and in fact your dentist will usually recommend regular check-ups so that any potential problems can be spotted and corrected early. The gum tissue and the bones that support the dentures will shift over time, which will, in turn, cause the dentures to fit less closely. When this occurs, there are a couple of different solutions: Relining and rebasing. Which are you going to need? Read on to find out! 

Relining: The First Repair Option 

Relining is the first "re" because it is the most common. When dentures are relined, the portion of the dentures that suctions directly onto the gums is coated with new material to give them a better fit. The main reason that relining may be necessary is bone resorption, the process of bone shrinkage following tooth extraction. Resorption continues even when the dentures are in place, and this bone shrinkage can force the dentures to slide around, or even just to shift slightly. To combat this problem, there are two types of relining. 

  • Hard Reline: A hard denture reline is done with a semi-rigid dental resin. This resin does have some flexibility, but is still fairly hard to the touch. The hard reline material will be precisely molded to the gumline, allowing for the most customized denture fit possible. 
  • Soft Reline: A soft reline is a temporary measure that may last for only a few months. For people who find the hard reline material to be too painful, the softer biodegradable material of the soft reline is often best. People who have gum inflammation, mouth injuries, or any type of gum damage may need to have soft relines until their mouth is healed, at which time they can have a more permanent hard reline. 

Rebasing: The Rare Repair Option 

Rebasing is rare in comparison to relining. While relining simply coats the denture base with new material, rebasing entirely replaces the denture base. In a rebasing procedure, the teeth are removed from the dentures first, and then the dentist will create a whole new base. 

To rebase the dentures, the dentist will make a mold of the mouth, and will then send that mold to a laboratory where the new base can be crafted based upon the dimensions of the patient's mouth. The denture teeth will then be placed within the resin, creating a perfectly-fitted set of dentures that looks exactly the same as the first. 

Rebasing does require the patient to go without their dentures for some time, until the laboratory creates the new ones. It is also more time consuming and more costly than relining. Fortunately, most denture wearers will do very well with a periodic relining when the dentures begin to shift. Talk to your dentist about which will work best for you today!

Baby Tooth as an Adult? You Are Not Alone

It was my secret for a long time, but I am finally sharing it -- I was an adult who still had a baby tooth. My dentist told me it shifted when my adult teeth came in instead of falling out. He also said I should have it pulled before it started causing dental problems, but I decided to keep it for a while. One day, during a dental check-up, my dentist found a cavity on the tooth next to it. He told me it was time to have it extracted, as it was close to the other tooth and making it hard for me to clean it. I had it taken out, and I don't miss it. I created this blog to tell other people with baby teeth as adults that they are not alone. Also, they can cause problems, so have them pulled if your dentist suggests it.
