Do it Yourself Denture Liners

Updated April 17, 2017

When you first get new dentures they fit tightly to the gums, but over time they may start to slip while you are eating or talking, and develop sore spots. This means they require relining. There is no need for an expensive visit to the dentist; you can do it yourself with a soft denture reline kit, which you can buy online. Dentures have a hard lining, while the kits have a more pliable material that is comfortable for those with sensitive gums.

Remove your dentures and clean them. Dry them thoroughly. Rinse your mouth and ensure no food particles are left on the gums. Smear petroleum jelly all over the outside of the dentures so the denture reline will not stick there.

Reline only one denture at a time. Place the powder in the mixing cup. Pour in the liquid and stir for no more than 10 seconds. Quickly pour into the top denture and place both dentures in your mouth. Bite down slowly but firmly. Hold this bite for three to five minutes. Take out the dentures and run cold water through the top one that you have just lined. Trim any excess material with a sharp knife. Reline the bottom denture following the same procedure.

Replace your soft denture reline when it becomes uncomfortable. Most people find they last from three months to two years.


Keep a spare reline kit for emergency repairs. Visit a dentist every two years: gum tissue and the underlying bone shrink as people age, and your dentures may eventually need to be remade.
