"Show me your teeth" prompt: "teeth are a big deal to Tooth and Pitch's could use some TLC ?"

Or: Tooth always has a way of talking Pitch into doing things he doesn't like. In this case, dental hygiene.

"Ngh..."

"Shhh, hold still." Tooth murmured gently, as she worked. "It's almost over."

A muscle flexed in Pitch's jaw, as he did everything to resist the temptation of simply pushing Tooth away, along with her instruments of torture.

Or not really torture, but they certainly felt like it. Tooth had decided she had wanted to give Pitch a dental check, and... he honestly had no idea why he had agreed to go along with it.

But here he was now, in a dentist chair, while she was ever so carefully cleaning his teeth. She had at least been happy to inform him beforehand, that he had no cavities (which to her was a miracle, since she was quite certain that the Boogeyman had never had a regular dental check for several hundreds of years).

Pitch was not the most sensitive of spirits, but the whole thing was just a little bit painful, especially since he could feel the metal of the tool scrape against the back of his teeth, and that there seemed to be a taste of copper in his mouth.

Finally however, it was almost over. When Tooth was finished with one tool, she allowed Pitch to sit up and spit and cleanse his mouth with some lukewarm water (cold water was anything but pleasant on ones teeth). When he felt his mouth was cleaned out, he gave her a weary look.

"Have we finished?"

"Almost. I promise the next bit will only take about ten minutes tops." Tooth said. "And then you can say that you are the proud owner of some nice, clean teeth!"

"Lucky me." Pitch sighed, but he laid back anyway and allowed her to get to work.

"And when we're done, think of how you can startle the others, by giving them a very shiny smile." Tooth added with a small smirk.

Pitch raised a brow at the mental image, as Tooth got to work by carefully, but thoroughly covering his teeth in what was a type of cleansing paste.

Well, he thought to himself, this is one reason she always manages to talk me into things.
