Re: Can visit to Dentist cause sinusitis
As dasw said it would be for your doctor to determine whether or not you managed to get a sinus infection as a result of a tooth infection. However, I have a pretty well pronounced heart murmur, and need to take anti-biotics for my dental cleanings... the only infections that I have heard of dentists worrying about transferring is bacterial sources getting into your blood stream and infecting your heart.
Now as to another thought, when you have an infection... any infection your immune system is under stress. As a result of system stress one of your bodies defenses is to produce mucus and purge the invader. This may have occured in your case, and if you didn't take decongestants or drain properly, the mucus in your sinuses may have proved a nice site for a sinus infection.
See your GP or ant ENT, they will be able to determine if it is a sinus infection or just irritation and congestion.
Best wishes and good luck.
