A yeast infection is not pleasant for anyone to have to experience.
An oral yeast infection can be all the more embarrassing as it is much harder to hide and also can be more painful than in any other place.
Knowing what causes of oral infection that are the most common is one way in which you can try your hardest to avoid it.
One of the common ways that you can get this type infection is by "catching" it from a partner.
If you have sexual activity with a partner that has a yeast infection then you can also get the infection and this applies for any kind of sexual contact, not just sexual intercourse.
Although having sexual contact with a person that has got an infection is not guaranteed to transfer the infection, it can happen and therefore should be avoided where possible.
Another of the causes of oral infection is a diet that is too high in sugar and it's byproducts.
This may include things such as cakes and bread and an increased amount of these types of products will obviously raise the chances of you getting an infection.
By cutting down on the yeast products and the foods that are high in sugar that you consume, you can lower the risks of getting an infection.
Believe it or not, a thrush infection could actually be caused by a weakened immune system.
Basically a weakened immune system does not have the "good" bacteria present to be able to fight the abundance of "bad" bacteria that is present in the body anyway and this will lead to the infection being able to do as they wish so to speak.
This is one of the causes of oral thrush and can be made more pronounced by things such as the contraceptive pill and also antibiotics which can actually cause the immune system to be not quite as strong as it once was.
