The Bluegrass appliance is a habit appliance with a pearl in the palatal vault that retrains the tongue as well as restraining it. Made to your Rx and shipped in 10 business days or faster.
Habit and Holding Bluegrass Appliance A .040 support archwire is soldered to bands on the upper first molars, and a vertical cage behind the lower anteriors stops tongue thrusting. The pearl, or roller, sits in the vault, so the tongue learns a new resting position. Searchers spell it blue grass or bluegrass, and it's the same appliance.

Questions about the Bluegrass Appliance.
Bluegrass appliance vs tongue crib: what's the difference?
The crib restrains the tongue. The Bluegrass adds a roller in the vault that retrains it.
Is a blue grass appliance the same as a bluegrass roller appliance?
Yes. Blue grass, bluegrass and bluegrass roller all describe the same appliance.
Is the Bluegrass used for tongue thrusting?
Yes. The vertical cage stops the thrust, and the pearl gives the tongue a new place to rest.
How is the Bluegrass appliance anchored?
A .040 support archwire is soldered to bands on the upper first molars.
