I walked into the side of my bathroom door late at night and hit my upper left front tooth. This was early Wednesday sometime past midnight, but I still can't stop obsessing over it. There was no pain after the impact, no blood, and nothing seemed to be knocked out of place or loosened. I've also checked for any gray coloration, but nothing so far.

However, I can't help but sense that the tooth just feels different. I don't know if I would even call it sensitivity, but something just feels off, as if something had been loosened or moved---which is strange because, as far as I can tell, neither of these happened to the tooth.

I'm going to go ahead and book an appointment with a dentist to alleviate my paranoia to some degree, but my tooth is probably fine, right? I'm just afraid that there may have been some subtle damage incurred that is invisible to the eye---what tests should I ask the dentist to perform?

Also, the tooth next to it (#7) seems have a minor inconsistency in the enamel, right within the gumline---it almost looks like a hole up close, but it isn't. I can't really get it unless I use my fingernail, but the area seems rough and devoid of enamel. Is this just demineralization, and an onset of a cavity? I'm thinking that this may be what is giving me that "off" feeling in my tooth---i.e., the odd sensation isn't stemming from the hit tooth, but the increasing sensitivity of the tooth next to it (#7).
