The teeth lip roll is an alternate lip roll created through a vibration created by biting down on the bottom lip. This technique was popularized by Mr. Wobbles.
How it's done
- Make sure your lips are moist
- Bite down on your bottom lip (but not too hard!)
- Take your bottom lip and move it to the right
- Pull in air as hard as you can, which will create a vibration of the bottom lip behind the teeth
- Now place the upper lip on the bottom lip for an added bass layer
