What Happens To Untreated Oral Thrush & When To Go To Doctor?

Most cases of thrush are benign and go away on its own with the use of an antifungal mouth wash or lozenges. Extremely mild instances of thrush may disappear without the need for therapeutic medicines. It typically requires about a fortnight of treatment with an oral antifungal medication to treat more acute thrush inflammations.

When the illness has spread to other parts, it may appear like cottage cheese and might bleed if they’re scratched and the patient may encounter pain or discomfort when swallowing.

What Happens To Untreated Oral Thrush?

Thrush may trigger a creamy feel in your mouth or a loss of taste. Typically, the antifungal drug can cure thrush. At times untreated thrush may lead to a more severe infection, mainly in extremely unwell individuals. Immediate attention and medication for thrush can help avoid that.

Oral thrush and other fungal infections are instigated by an overgrowth of the fungus Candida albicans also referred to as Candidiasis. You may develop an overgrowth of this fungus that induces oral thrush if you take certain drugs that decrease the number of healthy bacteria and fungus in your body, such as antibiotics.1,2

Hairy leukoplakia causes hairy, irregular white patches that resemble folds, normally on the sides of your mouth or tongue. It’s frequently misinterpreted for oral thrush, a disease marked by cottony white patches that can be scraped away, which is also widespread in individuals with a weakened immune system.

It’s often crucial to treating oral thrush in the initial onset as early as possible to control the infection. Physicians often recommend antifungal medicines in the form of mouth rinses, drugs, or lozenges. If left untreated, the signs will repeatedly persist, and your mouth will remain to feel unpleasant. Untreated oral thrush can run into extremely severe systemic fungal infections. If you have a weakened immune system, thrush may propagate to your esophagus or other portions of your body and can be more serious.

In a worse case scenario, it can even cause death. When Candida develops to the spot where it is in the bloodstream, it is referred to as Candida sepsis. During this phase, it is difficult to cure, and improvement is very challenging. The death rate from the final phase spread Candidiasis may reach sixty percent. The significance of treating it in its early stages cannot be overemphasized.3,4

Sometimes oral thrush can be a warning sign of an underlying disease, such as diabetes or weakened immune system because oral thrush can spread into the esophagus and from there to other internal organs, causing a serious, even life-threatening infection

To diagnose oral thrush, your doctor or dentist may request for physical examination and certain blood tests. During your physical examination, be ready to answer them to reserve time to go over any points you want to spend more.

The doctor can scrape off a small amount of the white matter from the infection and it will be analyzed under a microscope to rule out other conditions that are not caused by further underlying factors.5,6
