I call this a “bluegrass attachment.”
Kinda like a bluegrass appliance but smaller form so it can fit in a removable retainer.
Some of my doctors call it “spinners”
I got this idea (and the beads) from one if my doctors and used to make it exclusively for him, until one of my other doctors saw it and loved it! Now I make it for a few doctors.
The patients call it addictive for their tongue!
It’s kind of a training device to keep the tongue away from the front teeth
They are used to distract the tongue and keep it busy while the patient swallows and talks.
Here are the beads that I got from the doctor to make these. Make sure they are non-toxic. I believe you can pick them up from any hobby/crafts store.
