I have a small white patch under my partial denture. not painful?

See dentist first: Have the dentist check out the area. It may be a callused area from an ill fitting partial denture or something else. Have the dentist examine the area, make sure the partial is fitting and does not need to be remade or relined. If the dentist feels it is warranted, you may be referred to an oral surgeon for further evaluation.

Get check: White patches can have different diagnosis, please go to your dentist and get checked immediately

White patches: White patches under dentures are most often from irritation of the denture or fungal infections. However, they can be any number of other types of lesions. Some can be precancerous or cancerous, so it is imperative that you see your own dentist who can either diagnose and treat the problem or send you to an Oral Surgeon for a biopsy and definitive diagnosis.

White patch: Any lesion, painful or not, that lasts more than 2 weeks must be evaluated. Please immediately see your General Dentist or an Oral Surgeon. Although most white patches are transient and harmless, some are precancerous or cancerous.
