Is Your Horse Getting a Little Long in the Tooth?
This old saying usually means the horse (or person) is getting old. But even young horses can have teeth that are too long or have sharp points.
It's very important to understand how horse's teeth change as they mature.
Horse's teeth do not grow - they erupt. The entire permanent equine tooth is below the gum line. As a horse chews the exposed surface of the tooth is worn away. The tooth emerges (erupts) maintaining the needed length. By the time the horse is a senior only a stub will remain…if there is any tooth remaining.
A foal's teeth will start to erupt within a week of birth. The first set to appear will be the four incisors - located in the middle - two on the top and two on the bottom. The second set (intermediate) will appear a week or two later; the third set (corner incisors) appearing at about six months of age. There will be a total of 12 teeth in the front.
The premolars will also erupt at about two or three weeks of age. There are three on each side - top and bottom - for a total of 12 teeth in the back.
Over the next four plus years the permanent teeth will erupt. The erupting permanent teeth will push the shorter rooted baby teeth out. The baby teeth are sometimes called caps because they sit on top of the permanent tooth until they shed.
At the same time 12 more additional permanent molars will erupt. An adult mare usually has 36 permanent teeth. An adult male will usually have 40. Males usually develop canine teeth…adding to the number of teeth present. Some mares will also show canine teeth, but are small and short rooted.
Young growing horses need to have their teeth examined regularly. There are times when the cap may not shed or becomes lodged in the gum. The cap will need to be removed.
The lower jaw of the horse is slightly narrower than the upper. The lower jaw moves back and forth - grinding the lower teeth against the upper teeth during the chewing process. The surface of the teeth is worn away and eruption occurs in order to maintain the needed length.
As long as there is full lateral movement of the lower jaw and the diet is "horse friendly" the teeth should wear properly; but that is not always the case.
Wild horses with poor teeth died and did not reproduce. But most breeding programs do not take into consideration the structure of the jaw and quality of the teeth. Processed feeds now allow horses with genetic tooth defects to lead productive and useful lives. In most cases the owners are not aware a genetic tooth problem.
Most domesticated horse's diets are not natural. Eating hay from a manger instead of grazing does not allow the incisors (front teeth) to be worn down. The molars are still being worn away, but not the incisors. Eventually the molars will not meet properly because the incisors are too long.
The feeding of grain and processed commercial products instead of forage can also affect the molars.
When a horse eats long stem fiber - hay or grass, he grinds the material with a big wide lateral movement of the lower jaw. This allows the lower teeth to grind against the upper teeth and wear evenly.
If grains, chopped forage, pellets and processed feeds make up the majority of the diet the horse chews with a short quick lateral movement. The teeth do wear evenly and long points will develop.
Another cause of a long tooth is a missing corresponding tooth. There is nothing for the remaining tooth to wear against; but it will continue to erupt and cause chewing problems.
If you want your horse to become long in the tooth because of age, be sure to make regular dental appointments for him. An equine dentist or veterinarian can file the long tooth or point, allowing the horse to chew properly.
