Sometimes silicone may express out on the back edge of the palate or up and over the ridge to the front of your denture when relining with DenSureFit. Find out if, when and how to trim it.
Excess material on the outside of the denture can sometimes cause sore spots, so trimming might be necessary. See illustrations below.
NEWER DENTURE WEARERS: Trim the Nubs
If you have recently had extractions, it is CRITICAL that you consult your dentist before using DenSureFit. He/she must clear you and state that you ready to receive a soft reline before you use DenSureFit.
Once your dentist clears you for a soft reline, you are good to use DenSureFit. Your gums may still have indentations on the extraction sites. When you do your DenSureFit reline, the silicone will settle into those indentation creating silicone nubs on your liner. You'll need to clip/trim those nubs off so that the cured silicone does not protrude into your extraction sites as they continue to fill out. Trimming off the nubs will allow the gums to finish filling in properly as they continue to heal.
TRIMMING LOOSE HANGING SILICONE
As a general rule of thumb, silicone should be trimmed if it is loose and hanging, uncomfortable or if you can see it when you smile. Otherwise, if it is not bothering you, leave it there because it is likely contributing to a nice seal.
Illustration below: Trim silicone on the FRONT of the denture only if it is loose or flapping. Never trim directly up on top of the ridge.
If you are trimming on the back edge of the palate, hold your scissors at a 45 degree angle, angled AWAY from the denture. That way, the edge of the silicone will lay flat on the roof of the mouth.
TRIMMING ON THE TIGHT INSIDE CURVE OF A LOWER OR HORSESHOE UPPER DENTURE
Some lower dentures and upper horseshoe dentures have a tight squeeze on the inside curve of the denture making it difficult to trim. Try holding your scissors in the closed position. Use the CLOSED blades to scrape the excess silicone down and off of the acrylic.
