The MB 03 rotates onto the tongue, applying tongue pressure, but because the mouthpiece is curved, it wraps around the bars and lips instead of pinching. The barrel in the center applies approximately the same pressure on the tongue as a traditional three-piece mouthpiece, however, the barrel distributes the pressure more kindly and creates Independent Side Movement(TM). Sweet iron mouthpiece oxidizes and encourages salivation.
