A denture should not have sharp edges that cut into your gums. Simon explains that a rough area and a fit problem both deserve professional attention.
Do not accept repeated injury
If an edge catches, cuts or produces a sore each time you put the denture in, contact the provider. Explain whether it is new, recently repaired or has developed the problem after a long period of use.
An adjustment may help
The clinician can check for sharpness, overextension and the way the appliance sits in the mouth. A controlled adjustment and polish may be appropriate, but the underlying fit must also be considered. Removing a sharp edge does not necessarily fix every cause of discomfort.
Avoid a home repair
Do not sand the denture, trim it with household tools or apply glue to a damaged area. Bring all broken pieces if there has been a fracture. If an ulcer persists for more than three weeks, have it assessed by a dentist or GP rather than assuming the denture is the only explanation.
