We love the Centaur Stainless Steel Dr. Bristol Full Cheek with Twisted Copper Mouth Bit because it stops the pulling. The copper promotes salivation and relaxes the jaw.
Each side of the bit is perfectly balanced to assure total comfort and response. Lost wax cast and hand polished from the highest grade of 18/8 Stainless Steel. Lifetime guarantee against rust. Features pony-sized cheeks for sizes 4.5" & 4.75"
