Making it Fit with a Denture Reline

By Catherine M. Fascilla, D.D.S.

The underlying bone may shrink quickly during the first six months following the placement of new dentures. Shrinkage of gums and bones is especially noticeable after an immediate denture is inserted. If you have had your teeth extracted and dentures placed during the same appointment, you should visit the dentist within three to four months after you receive your new teeth. If your dentures become uncomfortable because they no longer fit, your dentist can adjust them with reline material. A denture reline is a relatively simple procedure to restore the proper fit of your teeth without making new dentures. There are two ways to reline dentures.

  1. A chair-side reline is done completely in the dental office. An acrylic mixture is placed in the denture. The denture is positioned in the mouth. Your teeth are brought together normally while the acrylic sets. The excess is trimmed and the denture is polished.
  2. A laboratory reline is done outside of the office. An impression is made within the denture and the denture is sent to the lab for processing.
  3. The laboratory reline is more effective and longer lasting than the office reline. Because the laboratory reline processes the new acrylic with heat and pressure, the acrylic is stronger and bonds better to the denture. The disadvantage is that you will not have your teeth for several hours to a couple of days, depending on the arrangements you dentist has with his or her dental lab. The chair side reline is done by you dentist in an hour or less. Both procedures provide acceptable ways to improve the fit and comfort of your dentures without making a new set.
