> Hooks and Ramps
Caused by slight misalignment of the upper and lower cheek teeth and often a result of an over or under bite. Hooks develop where part of the tooth is out of line and does not get wear from the opposing tooth as it should, instead forming a sharp hook. They are most prevalent on the first or last upper molars, causing riding problems due to the fact that when your horse is going well on the bit, it's lower jaw is relaxed and moves forward, hooks prevent this happening, and can cause pain in the turn as well as causing lesions and non-efficient feeding.
Ramps in contrast to hook's, are a gradual rising of the whole tooth from front to back, where hooks involve only part of the tooth. Ramps occur when the opposing upper premolar is retained, preventing normal eruption of the tooth. Problems such as inhibited chewing, excessive molar wear, and severe discomfort with the bit are common. Ramps need to be reduced slowly over time, to allow the opposing tooth to recover to normal table level.
