What is oral thrush?
Oral thrush is a fungal infection that develops in the mouth. It's caused by an overgrowth of Candida, a type of yeast that can normally be present in the mouth without causing problems.
What does oral thrush look like?
Oral thrush often appears as white, slightly raised patches or lesions inside the mouth. These patches can have a creamy or fluffy appearance and commonly develop on the tongue, although they can also appear on other areas of the mouth.
In some cases, the surrounding tissues may appear red or irritated.
What are the common symptoms of oral thrush?
Some patients with oral thrush experience a burning sensation or discomfort in their mouth, while others may not notice any symptoms at first.
One of the most recognizable signs is the appearance of white, raised patches on the tongue or other oral tissues. Some patients may also notice redness or irritation underneath these patches.
However, not every white patch in the mouth is oral thrush. For example, irritation or a burn from hot food or drinks can sometimes cause tissue changes that look similar.
If you notice an unusual white patch or another change in your mouth, it's important to schedule a dental examination so we can determine what's causing it.
What causes oral thrush?
Oral thrush can develop for several reasons. One common factor is a weakened or suppressed immune system, which can make it easier for Candida to grow excessively.
Another possible cause is the use of antibiotics. Antibiotics can disrupt the normal balance of bacteria in the mouth, allowing yeast to multiply. This doesn't necessarily mean that antibiotics suppress your immune system, but they can change the oral environment in a way that encourages fungal overgrowth.
Other factors, including certain medications and medical conditions, may also increase the risk of developing oral thrush.
How do you get rid of oral thrush?
The first thing I recommend is getting a professional evaluation. You can visit your dentist or primary care physician to determine whether the condition is oral thrush and identify any underlying factors that may be contributing to it.
There are antifungal medications available to treat oral thrush, and the appropriate treatment depends on the severity of the infection and your individual health.
Some mild cases may resolve when the contributing factors are addressed, but others require medication. That's why it's important to have the area evaluated rather than trying to diagnose or treat it on your own.
How long does oral thrush last if left untreated?
The duration of oral thrush depends on the severity of the infection and what's causing it. Some mild cases may improve on their own, particularly if the underlying contributing factor is temporary.
However, oral thrush doesn't always resolve without treatment, and there's no guaranteed timeline for it to disappear.
If you notice white patches, burning, or other unusual symptoms in your mouth, I recommend scheduling an evaluation. Any unexplained oral lesion that persists for more than two weeks should be examined by a dental or medical professional.
Are there complications if oral thrush is left untreated?
Yes, untreated oral thrush can sometimes lead to complications, particularly in patients who have weakened immune systems or other underlying medical conditions.
The infection may persist or become more uncomfortable, causing soreness, irritation, or difficulty eating. In certain higher-risk patients, Candida infections can also spread beyond the mouth, including into the esophagus.
Oral thrush itself doesn't generally weaken your immune system or automatically cause other infections. However, an underlying condition that increases your susceptibility to thrush may also affect your ability to fight infections.
That's why it's important to identify the cause and receive appropriate treatment when necessary.
