How to clean dentures after thrush
After oral thrush, clean dentures mechanically and disinfect them only with a denture-safe method while the mouth is treated.
The short answer
After oral thrush, clean dentures mechanically and disinfect them only with a denture-safe method while the mouth is treated. Remove the dentures at night unless your clinician gives a different instruction, and clean the mouth as well as the appliance.
What does oral thrush mean for your mouth and dentures?
Thrush is an overgrowth of Candida on the mouth lining. Denture surfaces, especially rough acrylic or the fitting surface, can retain organisms and contribute to recurrence if they are not cleaned.
A denture is usually acrylic resin, metal, or both, so heat, abrasives, bleach, and unsuitable chemicals can warp, scratch, corrode, or discolour it.
How can you clean and soak dentures after thrush?
Rinse the denture, brush all surfaces with a denture brush and non-abrasive cleanser, and soak it in the product and dilution specified for that denture material. Rinse thoroughly before wearing it.
Brush the tongue, palate, and remaining teeth gently, and complete the prescribed antifungal treatment. The dentist can inspect and polish a rough, cracked, or ill-fitting denture.
When should persistent thrush symptoms be reviewed?
Arrange review if burning, white patches, soreness, or redness persists after treatment, or if thrush repeatedly returns. Seek prompt medical care if swallowing is painful or difficult.
What should you ask about cleaning dentures after thrush?
Ask which cleanser and soaking solution suit the denture materials, how long to soak, and whether the denture needs adjustment or professional cleaning. Ask how to coordinate appliance care with antifungal treatment.
Frequently asked questions
Can I use household bleach on dentures?
Do not use an unapproved household chemical; choose a method labelled for the denture material.
Why did thrush come back?
Recurrence can involve retained organisms, an unclean appliance, mouth dryness, medicines, or another health factor that needs assessment.
