4 wis. teeth extractd while i had oral thrush. infectn seems to have progressed afterward. how likely is itt infec. entered bloodstream? what to do?

Only w/ immune prob: Thrush is caused by a fungus and is uncommon in healthy people unless they use inhalers or took antibiotics (often white seen in the mouth is misdiagnosed as trush) But regardless, spread of the fungus to the blood is extremely rare unless you have an underlying immune condition and it causes severe illness. If it spread to the throat and you are having pain with swallowing please be seen.

Speak to dentist: You need to discuss this and be seen by the dentist who extracted your teeth. We do not know your complete medical and dental history nor the specifics of your dental issues. As long as you are seen and treated appropriately in a reasonable time frame it is unlikely you will have any serious problems. But you do need to be seen and followed until healing is well established.
