Basic Mouthpieces

These mouthpieces are relatively mild. The curvature of the port allows for tongue relief (applying minimal pressure across the width of the tongue). And with rotation of the bit, the mouthpiece does not apply palate pressure (pressure applied to the roof of the mouth). Both mouthpieces will, however, apply pressure to the bars of the mouth that increase in severity as the mouthpiece diameter becomes smaller.

The Snaffle configuration by itself is a mild bit and one of the most universally used mouthpieces. It can be thick and mild on the bars and tongue when covered with rubber, or severe if used as a thin twisted wire mouthpiece. It can be combined with many variations such as a Copper Roller, Dr. Bristol, Dog Bone or Lifesaver mouthpiece.

Just as the Low and Medium Port mouthpieces provide tongue relief and apply pressure to the bars of the mouth, so does the high port.

The sweet iron mouth piece is a very popular mouthpiece that will rust with age. As it rusts, the mouthpiece becomes more flavorful. This sweet taste promotes the horse’s mouth to salivate. When a horse salivates, the tongue and lower jaw stay relaxed and the horse becomes more responsive.

Also termed as a "Cricket" mouthpiece, the Roller is commonly made of copper and can be combined with Medium and High Ports, Snaffle Mouths, Half-breeds and Spades. This mouthpiece will apply pressure as it lays across the tongue. It is an ideal mouth piece to pacify nervous horses and at the same time promotes salivation.

The Correction mouth, when used as part of a leverage bit, can be considered severe because it applies tongue pressure at the flexible joint of the port and bar pressure.

This mouthpiece provides some tongue relief and does apply bar pressure. It is recommended for horses that dislike palate pressure.
