Chronic Mouth Yeast Infection? – Nuke Your Dentures..

Candida-related denture stomatitis is an annoying chronic concern. Comparison of “topical application of miconazole three times per day for 30 days” versus “upper denture microwaved IN WATER (650 W per 6 min) three times per week for 30 days”. The microwave group was effective treatment – the other not

WARNING:

Obviously not meant for the faint of heart – dentures are not cheap and a melted plate would probably not be insured…Obviously could not be done if there was metal in the denture. I take no responsibility for anyone trying this…

  • “each patient had its maxillary denture individually immersed in a 600-mL beaker containing 200 mL of sterile distilled water. Each beaker was placed on the rotational plate in a domestic microwave oven (Model Sensor Crisp 38) and irradiated at 650 W for 6 min (21, 22) three times per week for 30 days.”
  • “Smears and cultures of palates and dentures of the groups Mw [microwave] and MwMz [microwave plus miconazole] exhibited absence of Candida at day 15 and 30 of treatment.”
  • “Miconazole (group Mz) neither caused significant reduction of palatal
    inflammation nor eradicated Candida from the dentures and palates.”
  • “Microwaving dentures was effective for the treatment of denture stomatitis. The recurrence of Candida on microwaved dentures at follow-up was dramatically reduced.”

Comment – Recently been suggested that 6 minutes on MEDIUM is much safer for dentures and 6 min high can cause “conformational changes in dentures”

Oral mucosal lesions in denture wearers.
Jainkittivong A, Aneksuk V, Langlais RP.   abstract here

  • 60.8% time lesions not related to denture wearing
  • traumatic ulcers and yeast infection are about evenly split (19.5% and 18.1%)- I have seen traumatic ulcers induced by antidepressants that cause bruxism (teeth grinding) and dry mouth
