What relief is safe tonight?

Remove the denture when your care instructions say to do so and keep it clean as directed. Arrange a dental or denture review instead of filing or reshaping it at home.

[3]

How is it checked?

A clinician can inspect the sore area and the denture, then consider how the appliance sits during use. That comparison helps identify whether the fit or the mouth needs attention.

[1][3]

What treatment may help?

Treatment depends on the finding. The denture may need professional adjustment, replacement planning, or care for the mouth. Do not make an irreversible change to the appliance yourself.

[2][3]

How can you reduce the problem?

Clean the denture and mouth according to the care instructions, and follow the advice about when to wear or remove it. Regular review matters when the fit changes.

[3][2]

When should you arrange care?

A persistent sore area can make denture use harder and may signal that the appliance needs attention. A review gives the mouth and the denture equal consideration.
