Oral Yeast Infections, Diagnoses & Treatment

Oral yeast infections also known as thrush can cause raised white curd-like patches that may have red borders on the tongue and can infect other mucous-membrane surfaces in the mouth. Scraping can remove these white patches, leaving a bleeding, painful surface.

Thrush is sometimes seen in infants although it is much more frequent in the terminally ill and people over 50 years of age.

Esophageal candidosis is much more prevalent in men than women.

Many times these infections go down into the throat and infect the pharynx or larynx. The most typical symptom is pain when swallowing or a sensation of food sticking in the throat. Hoarseness or altered vocalization will often occur at this point. There can also be a dry irritating cough and pain in the throat.

Diagnosing Oral Yeast Infections

For Esophageal candidosis or oral yeast infections in the throat, an endoscopy is the best method to make a firm diagnosis because the ulcer will be plainly visible. If an ulcer is visible it can be biopsied for a positive diagnosis.

Another diagnostic method is for your doctor to scrape the lesion and view the sample under a microscope. If hyphae or spores are seen then it is yeast.

Scrapping the infected are and then sending the sample to a lab for a culture can be used to determine the species, but most cases of esophageal candida are caused by candida albicans or candida tropicalis.

Tongue thrush can also appear yellowish as shown in this picture. Other oral yeast infection pictures can be found here, including pictures of yeast infections in the throat.

Look in the mirror with your tongue stuck out, if it is heavily coated with a white film, chances are you have an oral yeast infection. However, bad bacteria can also cause this condition so it might be a good idea to see a doctor and have them perform a culture to verify if it is yeast related or not.

If you have bad breath and also the white coated tongue, it is bad bacteria and not yeast. Yeast does not smell bad, bacteria does.

Sometimes these infections will also be found in the intestine. This webpage provides information on testing for yeast so you can determine if you might also have this in your intestine.

What Causes Oral Yeast Infections

  • ´╗┐Diabetes, leukemia and AIDS are common risk factors.

  • The use of steroid inhalers and people that wear dentures are also at a higher risk.

  • People with mercury dental fillings are 67% more likely to get oral yeast than those without them.

  • Thrush infections have been linked to a defect in the white blood cells or a confirmed low white blood cell count.

  • Oral sex with an infected female.

Low IgA immunoglobulin counts are also highly suspect since this is the immunoglobulin responsible for the defense of the mucousal linings in the body. IgA deficiency is also the most common immune system deficiency seen in humans, and it is usually for life. I suspect this is one of the primary causes of oral yeast infections and many yeast infections in general.

Medications for Oral Yeast Infections

Nystatin or sometimes Fluconazole is typically used to treat oral yeast infections.

Amphotericin B lozenges would be worth trying if Nystatin and Fluconazole are not effective medications. Doctors de Vries-Hospers HG, Mulder NH, Sleijfer DT, and van Saene HK found them to be very effective for neutropenic leukemia patients with oral candida yeast infections.

Other medications include Mycelex Troche or Clotrimazole, Itraconazole, and Posaconazole for people that are over 13 years of age.

It is best to send a culture from your mouth to a lab so the lab can determine what kills the yeast. That way your doctor can prescribe the most effective medication the first time.

Treating Oral Yeast Infections Naturally

Below is a list of medically proven natural products for treating oral yeast infections caused by candida yeast. Studies can be accessed from the Herbal Remedy page here.

It will be an experiment to find what works the best because not every species of yeast is susceptible to the same anti-fungal herbs or drugs for that matter.

Candidate is an herbal product that contains pau d'arco that is medically extracted in a tincture form. Laboratory tests have demonstrated that pau d'arco's anti-fungal properties are as potent as ketoconazole. It also contains lemon grass and Calendula officinalis which are proven anti-fungals that stimulate the immune system, repair the lining in the intestine, and are very good for the liver. Apply the drops directly to the thrush or dissolve in a little water and swish as long as possible before swallowing.

Pau d'arco can also be used by itself in tincture form or tea's. Drops should be applied directly to the lesions and it would be best to swish and swallow with the tea.

Cinnamon oil for yeast infections has been found to be deadly to drug resistant candida yeast and other fungal infections. The active ingredients are cinnamaldehyde, cinnamon oil vapors and eugenol. Preliminary human evidence confirms this effect in a clinical trial with AIDS patients suffering from oral candida (thrush) infections that improved with topical application of cinnamon oil. Antibacterial actions have also been demonstrated for cinnamon oil concentrates. The diterpenes in the volatile compound have shown anti-allergic activity as well. In addition, water extracts may help reduce ulcers. Apply directly to the thrush or dilute in a tbsp of coconut oil and let dissolve in your mouth.

Oregano oil for oral yeast infections has been tested extensively against molds, yeast, fungi, and candida in the scientific field. It is a proven candida yeast killer and the best results are achieved when the oregano oil contains 68.1% or more of carvacrol, which is the active ingredient in the oil. Apply directly to the thrush or dilute in a tbsp of coconut oil and let dissolve in your mouth.

Grapefruit seed extract in liquid form is another medically proven candida yeast killer. You can use it straight on the spots or add it to a little coconut oil if it's to hot.

Coconut oil for treating oral yeast explodes the nucleus of the yeast cell and is also good for treating intestinal or skin infections. Just take a tbls by mouth and hold in your mouth until it dissolves before swallowing. It also works well for skin yeast by applying directly on the infection.

Colostrum provides IgA antibodies and immunoglobulins that help the immune system. Chewable forms are the best to take whether treating oral thrush because you must let this dissolve in the mouth for any positive effects.

Another option that people are having good success with, is Biofase and Profase mixed together and sprinkled on the tongue. Then move it around in your mouth for as long as you can before rinsing it down with water. Below is a recent testimonial:

Hi Dan,

I just wanted to let you know that opening the biofase and profase and putting it on my tongue the last couple of days has performed wonders. All of the white on my tongue has gone away! My tongue is back to its normal pink color and it does not sting like it has been. I have been struggling with thrush for the last 6 months now, so I just want to say thank you so much for your advice!!

I had tried everything under the sun and spent thousands of dollars and nothing has worked, which has been so frustrating for me. So the fact that I am seeing results and my tongue is back to normal makes me so happy and finally feel like everything I have been doing is worth it now!


If you tested your stool for the presence of yeast in your intestine and it was positive, I highly recommend you under go the entire yeast infection treatment system. Yeast infections in two or more places are considered systemic infections and are best treated as such.
