White patches in your mouth? Could be oral thrush.
It's common, it's treatable, and it's usually not a big deal. But you do need to take care of it.
In one sentence: Oral thrush is a fungal infection (candidiasis) that causes creamy white patches on the tongue and inner cheeks, often triggered by antibiotics, dry mouth, or a weakened immune system.
Quick Answer
Oral thrush is just a fungal infection that happens when a yeast called Candida gets a little out of control in your mouth. You'll probably see creamy white bumps on your tongue, cheeks, or gums. It pops up more often in babies, older folks, or anyone whose immune system is a bit weak. Taking antibiotics can also trigger it. The good news? It's usually easy to fix with antifungal medicine.
Understanding Oral thrush
Everyone has a tiny bit of Candida yeast in their mouth and gut. It's totally normal. Your body's immune system and all the good bacteria usually keep it from growing too much. But sometimes, that balance gets thrown off, and the yeast takes over. That's when you get thrush.
So what throws off the balance? A few things. Antibiotics are a big one because they can wipe out the good bacteria that keep the yeast in line. Using a steroid inhaler for asthma can do it too. And if you have a weaker immune system, dry mouth, or dentures that don't fit right, you're more likely to get it. It's also why babies and the elderly get it more often—their immune systems just aren't as strong.
The classic sign of thrush is those white patches. If you wipe them away, the skin underneath will look red and sore. Some people also say it feels like they have cotton in their mouth, or they can't taste things properly. It can even make it tough to swallow and cause little cracks at the corners of your lips.
Your doctor or dentist will likely prescribe an antifungal medicine to clear it up. For a really mild case, you might get by with just salt water rinses or eating probiotic yogurt. Oh, and if you use an asthma inhaler, make sure to rinse your mouth with water right after. If you keep getting thrush over and over, it might be a sign that something else is going on with your health, so you'll want to get that checked out.
Common Causes
Weakened immune system
If you're dealing with something like HIV, diabetes, or cancer treatments, your body has a harder time fighting off the Candida yeast.
Antibiotics
These meds can kill the good bacteria that keep yeast in check, letting the Candida grow wild.
Inhaled corticosteroids
Using a steroid inhaler for asthma can let fungus grow in your mouth. Rinsing after you use it helps a lot.
Dry mouth
Not having enough saliva makes it easier for Candida to set up shop and multiply.
Dentures
Dentures that don't fit well or aren't cleaned regularly can become a breeding ground for thrush.
