Inferior & Superior Labial Frenulum
The inferior and superior labial frenulum are small flaps of connective tissue between the lip and gum line on the upper and lower jaw (maxilla and mandible).
In other words:
There are a few reasons as to why your dentures may be causing pain in this area.
As the swelling from surgery goes down and your ridge continues to shrink, your denture may begin to sit lower than it originally did, causing the denture to cut into the labial frenulum.
A reline can help to bulk the denture up once again, lifting it away from that area.
Another reason your denture may be causing pain to that area is that the denture was not made to provide adequate room for this tissue in the first place.
A quick adjustment can help provide more room so that the denture does not interfere with this tissue.
If you do find that you are having pain in this area, keep it clean by gargling with warm salt water. Benzodent can be applied to the area as well but if it is causing too much pain, it’s probably best to leave the denture out until the irritation subsides. Call your dentist and set up an appointment for any necessary adjustments to prevent further pain.
