Are you taking any antibiotics for any reason? Thrush (candidiasis) is a fungal infection. It tends to develop in the mouth in people who take antibiotics or have a dry mouth. Thrush often appears as a white, curdlike film coating the gums, including the gums under dentures, and the inside of the mouth. Thrush is usually painless, although the affected areas sometimes appear red and burn. Thrush may also affect the corners of the mouth, which become cracked, red, and dry. Antifungal creams and rinses are effective in most cases. When thrush is severe, antifungal drugs may be taken by mouth.
Lupus causes mouth sores that are usually painless. They are a mixture of red and white sores that can occur on the tongue, inside of the cheeks, roof of the mouth, and gums. Plaquenil usually helps with the mouth sores caused by Lupus.
You might want to speak to your doctor about these sores to determine exactly what they are and what the best treatment might be.
