I have had very bad teeth for over 11 years now they are broken have cavities absesses taste in my mouth my gums teeth hurt. Since bad teeth and they are getting worse I have been passing out while I chew food not all the times but at least 1-4 times a day. I have been to cardiologists and neurologists and all seems fine. I keep stating my tongue but am ignored. Can bad teeth cause some people to pass out

You say you have been to a cardiologist and a neurologist, but have you been to a dentist?

What J-9 said!
Why would you go to medical specialists and not a dentist? Because insurance doesn't cover it?
Doctors often overlook the teeth.
I have had two glaring examples in my life.
It doesn't matter what might be causing what, you clearly need to at the very least have the abscesses attended to because of infection.

Its for my wife she's been passing out for over 11 years and she was going to a dentist, but she gets medicaid through ssi because of her undiagnosed mysterious condition.

Are you near a dental school, or university medical center?
I wonder if she's having petit mal seizures brought on by chewing. Strange but you never know.
