I think I have a cavity!

I was the patient again on Monday and after using the diagnodent, my reading said that I have a cavity that has extended through the enamel. I just thought that it was a stain so I wasn't worried about it, but now I need to go to the dentist! Everything went smoothly, Sharli was even able to do one sealant on my premolar, but I still need more done. The order of everything makes sense now and I just need to continue getting faster at scaling. I am very excited for next semester!
