Brushing your teeth

A unicorn mare with a light blue coat, an ice-colored mane with a dark blue streak, and a cutie mark of an hourglass being named after a toothpaste company opened her shop with a sign saying, CHECK UP WITH COLGATE TODAY FOR SHINY TEETH!, not amusing some ponies. After a while, ponies wouldn't brush their teeth or even keep them CLEAN for a while, angering Colgate. After a short while, a certain pony who thinks humans are real came into the shop. It was Lyra. Lyra Heartstrings.

"Hello Lyra! What do you need today?"

"I can't brush my teeth yet after you showed me a few tips back then."

"That doesn't make sense. How come?"

"I don't have...hands hehe."

A quick angry breath from Colgate, she yelled:

"You know you have a horn! How can you be so DUMB?!"

This made Lyra whimper. Colgate apologized and said to use her horn to brush her teeth.

3 months later...

After getting some gifts from a doctor friend, Colgate found that there was:

A scalpel

A new mouth mirror

A stainless steel pick

A gold trophy for dentistry

6 random doctor magazines

A fedora (stylish yeah!)

A Top 100 Pony Music track

After wearing the fedora on and setting the gold trophy on her shelf, Colgate saw Lyra entering through the door. She set the Top 100 Pony Music track on her radio.

"Yeah uh...I can't brush my teeth. Sorry."

"..."

"Colgate...?

"........."

An angry glare with a serious frown was found on the dentist mare.

"...Nice hat?"

"YOU PIECE OF SHIT! WHY WOULD YOU COME HERE IF YOU CAN'T EVEN CLEAN YOUR TEETH?!

The music was still blaring on the radio.

Lyra whimpered and muttered something quiet. She then had a tear slide down her cheek.

Colgate just looked at her with a sad face. Then something in her body snapped. All the rage from the past years has controlled her.

She grabbed the scalpel and headed for Lyra. Lyra saw it and ran out of the way. After trying to slice her a few times, she instead locked Lyra in a room. She then grabbed a drill and drilled the doors. After a while, she heard Lyra scream a bloody scream she has never heard before. It was extremely louder then the music on the radio. She found she was hungry, so she went to Sugarcube Corner, Lyra still screaming.
