Bad Breath After Tooth Extraction
Hello. I had my upper molar (not wisdom tooth) extracted on Thursday, it has been about 48 hours since the extraction. I do not have any pain, but my breath smells bad. Is this normal? The tooth was extracted because there was an abscess. The dentist did not give me antibiotics and I am worried that I could get an infection. How would I know if I were developing an infection?
Also, I believe there may have been a slight perforation into my sinus as this morning there was a small amount of blood when I used a kleenex on my nose. (It also could have been from dry weather so I am not sure)
Are there things I can do to prevent infection? Does an odor coming from the extraction site necessarily mean infection or could it be from the blood ect.
