I have a filly that has an overbite. It seems to run in one bloodline in reining horses, and unfortunately, this bloodline is very popular right now. Anyway, we tried to fix her with the upper jaw wiring starting at two or three months old. It was a failure, because in this instance, the fillys lower teeth did not touch the upper fronts at all, so when the upper jaw was wired , the lower jaw of course kept growing, but the lower front teeth got hooked behind the uppers, and it also seemed as if the wiring caused her upper jaw to curve downward, it really didnt hold back the growth of it much. the curving downward, actually made the overbite worse, since the lower teeth were stuck behind the upper ones. If the lower teeth were partially touching on the uppers, I think this wiring solution might have worked. The only solution that would have worked for my horse would have been a bite plate to keep her mouth apart, and this would have had to stay in except during feeding time. Keeping her mouth and teeth apart would have allowed the lower teeth to move past the upper ones. Luckily this filly is very talented, performance wise and also can eat quite normally. her back teeth are completely normal and line up perfectly. She just needs her front teeth ground down every 8 or 9 months.
My mare does not have an overbite, in fact she has outstanding conformation and so does the filly, the mare has had foals before and since with no problems what so ever. but I have been gathering some info on the bloodline the sire had, and it seems to be fairly common in his bloodline.
