I had the idea for this for a while, but AcousticBrony decided on Tumblr that today was Colgate Day, so I had to upload it before the night was over.

LYRICS:
I'll cook up a solution with the toothpaste I've accrued
They say a brush in time saves nine but I'm just saving two
I've gathered the ingredients to combat tooth decay
There's hardly room for seconds when the seconds brush away

Watch as I work my dentist magic
Flouride that tastes like cinnamon
Swallow your pride and open wide and
open the portal, jump in!

Tooth stew, do you fear it Derpy Hooves?
Sometimes life is not a muffin served up on a silver spoon

Toss your sweets and,
save the day and,

dental flosses, toothpaste sauces
hourglasses, laughing gasses
minty icing, timeline splicing,
need some fillings, time for drillings

Derpy:
Colgate if you're hearing this be careful what you eat
I've got some cavities now cause those muffins were too sweet

My dentist chair's preheated and I've got you in my thrall
Let's beat these bums and save your gums by brushing the fourth wall!

Watch as I work my dentist magic
Teach everypony oral health
God help the ponies who don't brushie
Someday I'll find my true self
Someday I'll find my true self
