> Wave mouth
Wave complexes are when the molar arcades develop an uneven "wavelike" appearance. Usually some other defect in the mouth is the cause of the problem, causing the horse to adopt a defective chewing cycle leading to uneven wear of some teeth, and over eruption of others. Wave complexes can result in prematurely worn out teeth, pocketing of food and bacterial infection, inhibited chewing and grinding of food, and inability to relax the jaw while on the bit.
Due to the level of the defect and the fact it involves several teeth, correction of wave mouth is done over several sessions, to prevent the horse losing too much chewing surface in one visit. Over time tooth arcades displaying waves can be brought back to reasonable level chewing surfaces.
