Alright...well, went back to the dentist yesterday for other issues stemming from the antibiotics he had me on. He asked me to go ahead and come in so he could take another look. It's still there, not changing from the medication, so it will be biopsied for sure. He changed the date from the 13th to the 12th, so looks like I'll be in next Thursday!

Thanks everyone for the replies and support, and I'll be sure to be back to update!

How long does it normally take for biopsy results? I forgot to ask the dentist about it!
