Key Principles of DenSureFit

DenSureFit works on the principle of suction. DenSureFit is not adhesive or like adhesive. DenSureFit is a silicone liner that will remain on your denture for three months or longer and is intended to make your denture fit snug enough to create suction, which holds the denture in place.

DenSureFit is meant to be layered.

Each kit is intended to reline ONE denture plate. Most wearers need 2-3 silicone applicators/layers for the upper denture to get the dentures snug (DO NOT apply more than one layer to the palate). On the lower denture, 1-2 silicone applicators/layers are normal. If your dentures are still loose, they likely need another layer of silicone. See Upper Snug Up and Lower Snug Up for details.

DenSureFit is buildable.

You can add additional layers of silicone on top of previous layers, whether on day 1, day 10, or day 30. However, you must clean the denture each time, add primer if needed to bare spots, and then apply additional silicone according to the Upper Snug Up and Lower Snug Up Instructions.

Primer application is very important.

The primer bonding agent allows the silicone to adhere to the hard acrylic denture. The silicone cannot adhere to the denture without the primer. You must apply primer inside the denture but also on the ridges and over the ridges to anchor and secure the silicone edges over the top ridges of your denture. Without proper primer coverage, the silicone may lift on the edges and shorten the life of your liner. The primer is only necessary before the initial silicone layer and afterward on bare patches. Once the denture is covered with silicone, no more primer is needed. The new layer of silicone will adhere to the previous layer. See Step 2: Apply Primer for details.

DenSureFit is intended to cover the entire inside of your denture, travel up the side walls, and wrap around the top ridges of your denture. This creates the seal and the suction and keeps food and debris out from under the liner. This is called “flashing.” See the instructions later in this guide for specific details.

All DenSureFit kits are the same product, and can be used on either the upper or lower denture. Each kit is intended to reline ONE denture plate. The difference between the upper and lower kits is simply the volume of product in each kit. The upper kit includes three silicone applicators, and the lower kit includes two.

Upper denture first

If you have an upper and lower denture, you need to line your upper denture first. You need a great-fitting upper (with no adhesive necessary) before you can line your lower denture. The upper denture is needed to properly “seat” your lower denture. If your upper is “off” your lower will be “off.” This guide will provide all the details needed for a successful reline for your uppers and lowers.
