Ball Python Bite...picture included

Hello,

My ball python accidently bit my finger when she missed her meal which dangling in front of her in some tongs. That was about 2-3 weeks ago. The places never healed and are actually getting worse. Is it possible that somehow she broke off some teeth into my finger? I don't understand why it would be getting worse otherwise. I've been bit before by a kingsnake, and it was healed in NO time.

I am soaking it in Chlorhexidine, and then applying neosporin. I've been doing this since it started getting worse.

It's entirely possible.

I've removed teeth fom a bite for several days after it happened. In these instances the marks didn't heal until the tooth was removed.
I'd work on it a bit, it wouldn't surprise me at all if there wasn't a tooth in there.
Once it starts swelling a little and remains sore, you can sometimes just apply pressure on either side of it and the tooth will be pushed up to where you can get ahold of it.
