Like the old way of training and riding, man had a mold and the horse was broke and trained to fit that mold. In today's world of equine dentistry, people performing "dentistry" are also using the mold they were taught by someone else and attempting to make it fit all horses that they do. I believe, we should tailor equine dentistry to fit the horse and its specific riding discipline. I have found that performing whole mouth equine dentistry includes all the following points:

Point 1- Head Symmetry

          The shape of a horse’s head differs according to breed. Therefore, special attention should be focused on bone and muscle structure of the head. Before a dentist even picks up an instrument, he or she should check out the muscle in the face to see how the horse has been chewing. Is there any swelling or discharge? Are there any injuries, broken bones, a twisted jaw, or asymmetries? Are the TMJ joints sensitive to the touch? Such signs can tell me what I can expect before even looking in the horse’s mouth.

Point 2 – Body Structure

          Like the horse’s head, the body is also built differently. Abnormalities in the body can also be a sign of dental problems. Is the horse bending his neck and flexing at the poll where he should or is he flexing between vertebrae C1 and C2 (indication that his jaw is hanging up and not allowing for the neck and poll to flex)? Are the withers, croup, and flanks rounded with good muscle tone or are they atrophied? Is there unexplainable lameness, especially in the hocks? Are there signs of chronic lameness or severe injury such as bowed tendons, founder, etc.? Lameness can affect the wear pattern in the teeth and also needs to be addressed. Even if the teeth were addressed, after only a few months the same problems will reoccur because lameness can be directly related to teeth and vice versa.

Point 3 – Back Teeth (Molars)

          After observing the head and body structure, the dentist should now examine the molars. My goal when balancing the molars is to enhance the biomechanical movement of the lower jaw (anterior and posterior movement) with the least amount of tooth reduction. When the horse lowers its head to eat, the bottom jaw will move forward and the incisors and molars will meet. The same thing happens when the horse is asked to perform various tasks. If the horse has a malocclusion, he will not round up or collect and this will result in fighting the bit. I have found when balancing the horse and eliminating the malocclusion, the horse will perform excellently. This is also based on yearly dental maintenance. Once the horse has balanced molars, they will need to be maintained with yearly visits. Regular dentists who come out only to float the sharp points off will over look most malocclusions. Thus resulting in labeling the horse as stubborn or hard to handle, when he should be identified as a horse in pain.

Point 4 – Front Teeth (Incisors)

          After balancing the molars, the dentist will need to balance the incisors. Most horses will need incisors reduced prior to balancing the molars, because the horse is not in its natural grazing state as would occur in the wild. In the wild, a horse generally grazes for about fourteen to eighteen hours a day. The abrasive silica in the grass will naturally wear down the front teeth. Unfortunately, with today’s horses living in unnatural environments (stalls, paddocks, and pastures), natural wear is not possible. Incisors are to be used for prolonged periods of grazing. Upon first looking at the horses incisors, we will find them excessive in length in older horses, as well as wedged or jagged. In younger horses we often find caps or retained caps. Which brings me to what I feel is very important at this point. That being, after checking the front and back teeth and observing the pathology of all the teeth, I perform the necessary incisor work to correct any problems found with the incisors and having reduced the length of them to give the horse a 3-point balance (incisor, molars, and TMJ’s).

Point 5 – Checking Your Work

          When the dentist finishes doing work on the teeth, he or she should manually move the lower jaw side to side and back and forth checking the occlusion or contact of the molars. This gives a good idea of how well the teeth meet. However, manually moving the lower jaw does not give you an accurate reading, because the teeth still could be riding on a high tooth giving the dentist the impression that the horse is balanced. The dentist should back up the evaluation with looking down the horse molar table with a light and look to see if all the teeth in the arcade are meeting at the same time. This gives you the best accurate reading when checking for occlusion and checking to see if the horse is balanced properly. The bottom line, is a dentist should be checking for the natural balance of equal pressure among the incisors, molars and TMJ.

Point 6 – Handling Horses

          Horsemanship today involves compassion, understanding the horses’ needs, and intent. The horses’ needs should come first while doing dentistry, although this is not the norm in dentistry today. Due to today’s advancements in dentistry, often times a horse will need to be sedated so that technology can allow us to pin point the problems and address them with minimal amount of tooth lost and time in the horses’ mouth. If the speculum (a device that holds the mouth open) is not used, it is not possible to see and feel everything in the back of the mouth or to get the work done properly. With the horse properly sedated, it allows the dentist to get in and out in less time with the use of electrically powered instruments, and allows the dentist to be thorough in his work. Performing dentistry on unsedated horses does not allow the dentist to use electrically powered instruments, a full mouth speculum, and in most cases, not enough time to work on the horse properly. However, with a sedated horse, the horse is less stressed, the experience is a positive one, and there is minimal to no soft tissue damage. In the long run, the horse is happier and in some cases, depending on how bad the horses mouth is, the horse can be rode in the same day.

          I feel that horses today are getting the short end of the crop, so to speak, when it comes to dentistry. The horses tell us what they need, and yet we are unable to read the signs. Educate yourself and know what to look for. Make sure your dentist knows what he or she is looking for and can determine what should be done for the horse’s best interest, not only in doing dentistry, but when handling the horse as well. Horse dentistry is just a piece of the whole horse puzzle. There is no “I” in team and we, as horse professionals, need to work together to help the Horse.
