When dentures are new they fit snugly against the gums, but over time the gum tissue shrinks and the dentures become loose. When dentures are loose they can slip and develop pressure points. This can be embarrassing and painful. When this happens, you need to get your dentures relined, which is the process of adding material to the pink base of the dentures to make them fit snugly again. Dentist visits can be costly and will leave you without any dentures for a couple of days. An alternative is a do-it-yourself denture reline, using kits that are available on the Internet for about £9 to £19 as of April 2011.
Remove your dentures. Clean them thoroughly with soap and a soft toothbrush. Dry them carefully with paper towels. Use a mouthwash to rinse your mouth and ensure no food particles are left on the gums. Rub petroleum jelly on the outside of your dentures so that any reline material that oozes out will not stick to the outside.
Organise everything in front of you before you mix the products in the reline kit, as they activate very quickly. Reline one denture at a time.
Place the powder and liquid together in a mixing cup and stir together. Pour into the denture when it reaches the consistency of thick honey and spread it around. Place both dentures in your mouth and bite down firmly but without clenching your teeth. Hold this for three minutes, then take out the relined denture. Rinse it under cold water and trim excess material from it with a knife. Put the denture back in your mouth and gently bite down for another three minutes. Repeat the procedure with the second denture
Mix baking soda into some cold water and soak the newly relined dentures for at least 30 minutes. This will remove the taste and odour, which can be unpleasant. The reline can last from two months to two years and should be replaced when it becomes loose or uncomfortable.
