The Surprising, Yet Most Common Causes of Oral Thrush



Oral thrush is not common among healthy adults. If you’re one and you think you’ve got thrush, it’s most likely because of one of the following reasons:


Antibiotics are a common cause of oral thrush in healthy adults, since they affect the healthy bacteria in your mouth and gut. If you’re taking antibiotics, remember to eat plenty of probiotics, to make up for the loss of beneficial bacteria.


Candida albicans loves ethanol and yeast-rich environments, and that’s exactly what alcohol contributes to. If you think you’ve got a candida infection, you should stay away from beer and other similar products, since they increase the number of candida colonies in your mouth and gut. Try to include as many probiotics as possible (stuff like yogurt, cheese, and milk), get specialist help, and use home remedies to cure your infection.


Smoking is a serious risk factor for oral thrush: it damages the oral tissue, kills the beneficial organisms in your mouth, and helps spread the candida infection.

If possible, avoid smoking at all costs, especially if you’re experiencing thrush symptoms. Consult your doctor and start the treatment as soon as possible.

Unprotected sex

Oral thrush may be passed on from partner to partner during sexual intercourse, but that’s not necessarily the case. However, if you’ve got it, it’s best to get your partner treated, too. This way you’ll prevent an unpleasant situation of back and forth re-infection, and you’ll speed up the healing time.


Stress may cause thrush in healthy adults, since it affects both the eating habits and the digestive processes. It’s best to address your doctor as soon as you notice the first symptoms, so as to start the treatment as soon as possible. Controlling your stress and taking care of your diet will reduce the risk of getting thrush.
