Foals should be checked for dental malformations such as parrot mouth, or sow mouth.
Two - four and a half year olds may have wolf teeth, caps and very sharp enamel points.
Non-riding horses such as broodmares or retired horses have different dental requirements than performance horses.
Geldings and stallions have four "canine" teeth (not to be confused with "wolf" teeth) that are on the bars of the mouth and need to be reduced. They can interfere with the bit if improperly fitted.
Geriatric/aged horses should be checked for loose teeth, missing teeth, abscesses, decayed teeth, sharp points, irregular wear, tumors.
Some breeds come with their own set of dental issues and concerns.
Performance horses may need to be on a more frequent examination schedule. Comfort in the bridle can be maximized by installing bit seats and ensuring proper fit of bits and tack.
