Oral thrush is caused by the overproduction of a fungus called Candida albicans. While it can affect anyone, it is most common in babies, in those taking antibiotics for prolonged periods, and in those with compromised immune systems or who use corticosteroid inhalers. Mild cases generally cause no symptoms other than white patches inside the mouth, but in severe cases, painful lesions may develop on the gums, the roof of the mouth or the back of the throat. The lesions may bleed when touched. Hydrogen peroxide rinses can help clear mild cases of oral thrush in most healthy adults.
Step 1
Brush your teeth and the inside of your mouth with a soft-bristled toothbrush. This will clean your teeth gently and help dislodge the patches of thrush. You may experience mild bleeding and discomfort.
Step 2
Rinse your mouth with a solution of equal parts water and 3 percent hydrogen peroxide. Pour the solution into your mouth, gargle for approximately 30 seconds, and then spit the solution out. Do not brush your teeth or use a mouthwash for at least one hour after using the peroxide.
Step 3
Use the peroxide rinse three to four times per day until your symptoms are completely gone. If there is no significant improvement in your symptoms after two weeks, or if the infection spreads, call your doctor for an appointment. You may require prescription medication. The National Institutes of Health recommends seeking medical attention if you develop pain or problems swallowing.
Step 4
Pour undiluted peroxide over your toothbrush before storing it. This will kill any yeast that remains on the toothbrush to reduce the risk of re-infection. Isopropyl rubbing alcohol is also effective at sterilizing your toothbrush.
Tips and Warnings
- Eating unsweetened yogurt with acidophilus can speed recovery from oral thrush by restoring the natural bacterial flora inside your mouth, according to MayoClinic.com.
- Do not swallow the hydrogen peroxide solution.
