When dentures don't fit right
Dentures that move, rub, click, or cause sore spots may need an adjustment, relining, repair, or replacement rather than more adhesive.
The short answer
A poorly fitting denture may need a chairside adjustment, laboratory reline, repair, or replacement. Movement and soreness can follow ridge changes, an inaccurate base, worn teeth, or an altered bite.
How can changes beneath a denture affect its fit?
A denture rests on mucosa over the residual alveolar ridge, which can change after tooth loss. Saliva, jaw movement, chewing forces, and upper-lower tooth contacts affect retention.
What should you avoid doing to an ill-fitting denture?
Do not grind or bend it yourself. The dentist can inspect pressure areas, check the bite, adjust acrylic or tooth contacts, and decide whether a reline or remake is needed.
When does poor denture fit need dental assessment?
Arrange care for persistent sores, bleeding, pain, chewing difficulty, or sudden looseness. Prompt assessment is needed after a break or signs of infection.
Is the problem caused by the base, bite, ridge, or damage?
Ask whether the problem is the base, bite, ridge, or appliance damage. Ask whether adjustment, reline, repair, or replacement is appropriate.
Frequently asked questions
Could this have more than one cause?
Yes. Several oral tissues or materials can produce similar symptoms, so examination may be needed to distinguish them.
What should I record before an appointment?
Note when it began, where it occurs, what triggers it, and any swelling, bleeding, sensitivity, discharge, or appliance change.
