Trust Sweet Iron Loose ring Dr. Bristol

This double-jointed mouthpiece bit with a flat middle piece is made of Sweet Iron alloy, designed to stimulate salivation through surface rust that forms when moistened.

• The bit acts mainly on the tongue due to its angled, flat plate.
• The side piece consists of loose rings allowing for more freedom of movement in the mouth.
• The special Sweet Iron alloy forms surface rust when moistened, which tastes sweet and stimulates salivation.
