Should thrush lasts for weeks?

Oral thrush is a yeast infection that leaves distinctive cottage cheese-like sores on the tongue. Though they're unsightly, these sores usually clear up on their own in about two weeks. If they don't go away after a couple of weeks, it's time to call your doctor. If your baby has thrush, contact her pediatrician.

Thrush is common, especially in babies, and it's usually harmless. However, if thrush persists, it can lead to swallowing and feeding problems. If the sores don't go away, your doctor or your child's pediatrician can prescribe an antifungal medication to clear up the fungus that causes thrush.

Your dentist should examine any mouth sore that lasts a week or longer. Oral thrush, or candidiasis, occurs when the yeast Candida albicans reproduce in large numbers. It is a fungal infection. While uncomfortable and often unsightly, this will typically go away through good oral hygiene, cleaning and removing dentures at night and saliva replacement, if due to dry mouth. See your dentist if it persists for treatment.
