As David mentioned, could be thrush, which is a fungal infection, basically a yeast infection out of control, if it can be scraped off. They can do an oral visual to diagnose of do a culture from the scraping. Thrush feeds on sugar, alcohol, and yeast, so avoiding those help. The drug of choice is fluconozole, cltromizole. Some say taking pro biopics, eating yogurt helps, , but some are against adding more bacteria to the body. Show your doctor.
