That same tooth, according to my dentist ages ago, was being pushed upon by my lower wisdom tooth, which was possibly exposing a nerve, thus the "YIKES!" feeling I had anytime anything cold would hit that area of my mouth. So, at his suggestion, I made an appointment with an oral surgeon, and had both lower wisdom teeth extracted at the same time. Shortly after the healing was finished and the stitches had dissolved, I no longer experienced any pains in that area of my mouth. This was back in 1999.
Fast forward to April 1, 2008, and what has now happened. The tooth that developed the chip, and was causing the "Yikes!" feeling back then, has had a filling in it for about 20 some-odd years now. Not sure when the chip occured, most likely by my guess while I was sleeping... probably swallowed it. Oddly enough, no problems with cold stuff (not yet anyway), just that "jaggy" feeling on the right side of my tongue.
Tomorrow morning, I'm going to call and make an appointment with the dentist to get it seen about. Since I don't consider it quite an "emergency" at this point, I'm going to see if he can work me in on one of my days off, either this coming Monday or Tuesday, or next Monday or Tuesday, so I don't have to miss any work (because of Wal-Mart's "no such thing as an excused day off" policy). In the meantime, I'll try to favor the left side of my mouth for chewing.
Got a chip in a different tooth back in '99, shortly after the wisdom extractions, the dentist installed a crown over that one. If this tooth is hopeless, might have to have it yanked... hope not though.
