Doctors prescribe antifungal medications to a cure yeast infection in the mouth, a condition commonly known as oral thrush, according to WebMD. This condition may indicate other diseases, so patients may also need to seek medical treatment for an underlying condition.
Prescription antifungal medications used for oral thrush come in the form of lozenges, liquids and tablets, and they are normally taken over a course of 10 to 14 days, according to WebMD. Treatment is normally effective in otherwise healthy patients, but those with compromised immune systems encounter more difficulty ridding themselves of the infection. A dentist generally prescribes a treatment regimen based on factors such as age and health.
When oral thrush occurs in nursing mothers and their babies, a doctor may prescribe a mild antifungal treatment while the mother is given an antifungal cream to apply to her breasts, as Mayo Clinic notes. If standard antifungal medications are unsuccessful in patients with compromised immune systems, they may be prescribed the medication amphotericin B as a last resort. After treatment, patients can prevent future Candida infections in the mouth by practicing good oral hygiene, receiving regular dental check-ups, limiting sugar intake and avoiding the overuse of mouthwash, as WebMD recommends.
