Peter and Ann arrived at Ann's apartment, and she led Peter straight to her bedroom. She opened the drawer of the bedside table and took a dental mirror and an explorer from there.

"Oh, it looks like you are very well prepared," Peter said surprised.

"Well, I have a bit of interest in dental stuff."

There was an adjustable table lamp on the bedside table, and Ann switched it on. It was unusually bright, almost like a dental light.

"I installed an extra bright light bulb," she said, "I think it's good enough, you don't need a flashlight. Then you have both hands free to use the mirror and the explorer."

Ann lay down on her back on the bed so that her head was under the lamp.

"Okay, please have a look what is going on in there," she said and opened her mouth wide open.

Peter had never held a dental mirror in his hands before, so he wasn't quite sure what to do. He was feeling really excited and nervous at the same time. He put the mirror carefully in Ann's mouth and learned that he can use it to reflect the light to illuminate a specific tooth. He noticed that Ann had four amalgam fillings in total: one in the lower right molar as he had seen already, one in the first upper left premolar, and one in both upper first molars.

"It looks like you have some silver fillings. How did you get those, I thought dentists don't do them anymore?" Peter asked.

"Oh, actually I asked for them. I had a couple of white fillings when I was a child, but they fell out, and I heard that amalgam fillings last longer. And to be honest, I think they look kind of cool."

"I think I agree. I never thought about it before, but I like your fillings. Your teeth are really clean and those fillings are shiny; it's a beautiful combination."

Peter picked up the explored to check the tooth with a possible cavity. In the bright light, he noticed it wasn't just a small dark spot on that tooth, but the area around the spot also looked darker, like a shadow inside the tooth. He used the explorer to poke the dark spot, and the explorer got stuck in it.

"Auch," Ann sighed.

"Oh yes, you definitely have a cavity there. And I think it might be quite deep. You need to see a real dentist soon."

"Yes, I think I knew it already. But can you check also the other teeth if there is anything to worry about?"

Peter started to systematically explore all of Ann's teeth one by one. Most of her teeth looked fine, she apparently took a good care of them. But then he reached the upper right first molar with an amalgam filling and noticed a crack when exploring the edge of the filling.

"I think the filling in your upper molar is broken. I can see it moving when I try it with the explorer," he said.

He tried to pull the filling with the explorer once more. This time the whole filling fell out. Ann uttered a brief moan. Just a large hole with sharp edges was left in the place of the filling.

"I'm really, really sorry Ann, I think you just lost a filling. I think you need to see a real dentist very soon now. It's my fault, is there anything I can do now?"

"Don't worry about it. If the filling was cracked, it was just a question of time when it falls out. It's not your fault. If you open the drawer, you can find a small tube of temporary filling stuff and cotton swabs. You can use a cotton swab to clean and dry the hole and then fill it with the temporary stuff."

Peter opened the drawer and picked up a cotton swab and the temporary filling material tube. He poked the cotton swab in the hole and moved it around. His hand was shaking as he was so nervous. Ann moaned quietly.

"Is it painful?" Peter asked.

"Yes, a little bit, but it's fine. Please continue."

Peter moved the cotton swab a couple of rounds more. Then he squeezed some filler out of the tube in the hole and flattened it using the cotton swab.

"It's ready now. Does it feel ok?" Peter asked.

Ann sat up and looked at him smiling.

"Thank you so much, Peter! You are like a real dental professional!"

Ann embraced Peter and kissed him. She moved her tongue inside his mouth and probed his teeth with her tongue. She could feel the smooth texture of the biting surfaces, differing from the groovy texture of natural teeth, hinting that Peter had several composite fillings in his premolars. The idea of his dental work fascinated her and turned her seriously on. Peter was surprised by her sudden outburst of affection but played along, and they kissed long and passionately.

"Oh, that was really cool! What are we going to do next?" Peter asked.

"Hmm, what do you think? I think it's your turn to be the patient," Ann replied, smiling mysteriously.
