How to put it together
- 1
Cut out a head hole and two wide armholes in the cardboard box using a utility knife.
- 2
Paint the entire exterior of the box bright white and let it dry completely.
- 3
Use blue and green paint or markers to write 'DENTAL FLOSS' and draw a small mint leaf or tooth logo on the front of the box.
- 4
Attach a small square of silver metallic tape to the top corner of the box to represent the metal floss cutter.
- 5
Poke a small hole next to the silver cutter, thread the white cotton rope through it, and knot it on the inside so it stays secure.
- 6
Put on your white base clothes, slip the decorated box over your head, and let the extra rope trail behind you or loop it around your hand.
Makeup & hair
Keep your hair neat and simple. For makeup, focus on a bright, clean smile, or add a touch of light blue face glitter for a fresh, minty sparkle.

Dental Floss costume FAQ
- How do I make the dental floss look realistic?
- Use thick white cotton rope or clothesline cord. Let a few feet of it dangle from the 'cutter' tab on your box, and loop some of it around your hand.
- What is the easiest way to make this last-minute?
- Wear a plain white t-shirt and use fabric markers to draw a dental floss dispenser logo on the front, then drape a piece of white yarn over your shoulder.
- Is this costume comfortable to sit down in?
- If you use a rigid cardboard box, sitting can be tricky. For better mobility, opt for a sandwich-board style hanging by straps, which you can easily slip off when sitting.
Did you know? Dental floss was first invented in 1815 by a New Orleans dentist named Levi Spear Parmly, who recommended his patients use thin silk thread to clean between their teeth.
