Dental update and conclusion:
I went this morning to get the offending molar pulled. I guess I really lucked out with the dentist we have here in the Philippines. I hate getting needles in my mouth worse than the pain of dental procedures. In this case though, I have no complaint. He was patient and gentle with the needle and even though he had to repeat the injections ("your a big guy"), it was pain free.
The extraction was over before I realized it. I had to ask him twice if he got the tooth and if he got it all. Then he showed me the infected part of the tooth. It was absolutely the right call to pull it.
Wow.
The total bill: first visit and xray $10. Second visit for extraction $30.
I'm a happy camper.
