How to Sign "Brush Teeth"
To sign 'brush teeth', form your dominant hand into a '1' handshape by extending your index finger. Hold your index finger horizontally just in front of your teeth. Move your finger back and forth a few times, mimicking the natural motion of brushing your teeth.
Visual Logic(Etymology)
This sign is highly iconic, meaning it looks exactly like the action it represents. The extended index finger acts as a visual classifier for a long, thin object—in this case, a toothbrush—and the side-to-side movement mimics the daily routine of brushing.
Signing Tips
Keep your index finger hovering just slightly in front of your lips. You can part your lips slightly to show your teeth, which adds clear visual context to the sign. Keep the side-to-side motion small and brisk.
Common Mistakes
A common mistake is actually touching the teeth or putting the finger inside the mouth. Your finger should remain outside the mouth, hovering just in front of your lips. Another mistake is using the whole hand instead of isolating the index finger.
Regional Variations
This sign is widely used and understood across the ASL community with minimal regional variation.

Frequently Asked Questions
Does this sign mean 'toothbrush' as well?

Yes! In ASL, nouns and verbs are often related. The same sign can mean the noun 'toothbrush' or the verb 'to brush teeth'. Often, the noun uses a smaller, quicker double movement, while the verb uses a slightly wider, continuous motion.

Do I need to bare my teeth when signing this?

You don't need to exaggerate it, but parting your lips slightly into a smile to reveal your teeth makes the sign look much more natural and provides great visual context.

Which hand should I use to sign 'brush teeth'?

You should use your dominant hand. If you are right-handed, use your right index finger; if you are left-handed, use your left. It should feel exactly like the hand you naturally use to hold a real toothbrush.
