By the time we see many horses, the challenge isn't figuring out what to removeโฆ
It's recognizing how much has already been removed.
Years of excessive or aggressive floating can leave teeth so reduced that there simply isn't enough dental material remaining to make the changes a horse may now need.
And sometimes, the most appropriate decision is to leave the tooth alone and allow more tooth to erupt.
๐๐ก๐ฒ ๐๐จ๐๐ฌ ๐ญ๐ก๐๐ญ ๐ฆ๐๐ญ๐ญ๐๐ซ?
Because the teeth do not exist in isolation from the rest of the horse.
Their relationship with the mandible, temporomandibular joint (TMJ), hyoid, cranial bones, cranial nerves, craniosacral system, fascia, and upper cervical spine-C0, C1, and C2, is part of a much larger functional system.
From an osteopathic perspective, we aren't looking at the teeth as simply structures that need to be โfloated.โ We are looking at how the entire stomatognathic system interacts with the rest of the body.
When we make osteopathic changes through the body, the dental structures need to be capable of supporting those changes.
If the teeth have been reduced too far, they may no longer provide the occlusal relationship necessary to support normal mandibular movement and TMJ function.
And that relationship matters.

So, what exactly is the pulp?
The pulp is the living, innermost portion of the tooth. It contains connective tissue, blood vessels, nerve fibers, and odontoblasts which are the cells responsible for producing dentin.
In the horse's cheek teeth, the pulp isn't one simple hollow chamber. Equine cheek teeth contain a complex pulp cavity system with multiple pulp horns. Depending on the tooth, individual cheek teeth can contain numerous pulp horns, some of which may lie surprisingly close to the occlusal surface.
It isn't simply an empty space.
It is living tissue.
The horse's hypsodont teeth are uniquely adapted to continual wear. Throughout the horse's life, the pulp produces dentin beneath the occlusal surface to help protect the pulp from being exposed as the tooth wears.
That protective dentin is incredibly important.
Research has demonstrated that the thickness of sub-occlusal secondary dentin can vary dramatically, not only between individual horses and teeth, but even between individual pulp horns within the same tooth. In some areas, the protective dentin has been measured at only a few millimeters.
That means we cannot assume that a certain amount of tooth reduction is automatically safe simply because the same amount was removed from another tooth or another horse.
Every tooth is not the same.
And when excessive tooth is removed, the pulp may be brought dangerously close to the occlusal surface or exposed.
One study examining overgrown equine cheek teeth found that reducing certain overgrowths completely to the level of adjacent teeth would have resulted in occlusal pulp exposure in 58% of the teeth studied, leading the authors to recommend gradual reduction of larger overgrowths over time.
There is another consideration:
๐๐๐๐ญ.
Motorized dental instruments can generate significant heat within the tooth. Research measuring pulpal temperatures during mechanical reduction found that prolonged use of motorized instruments increased the likelihood of reaching potentially damaging pulpal temperatures. Greater dentinal thickness and water cooling were protective factors.
So excessive reduction isn't simply about how much tooth was removed.
It is also about what may have happened to the living structures underneath it.
And pulpal injury can be extremely painful.

If you've ever had a filling or other dental work, you know your dentist is concerned with how much healthy tooth structure remains between the surface and the pulp.
Human dentistry even uses procedures such as an indirect pulp cap when the pulp is very close to exposure, with the goal of protecting the pulp and supporting the tooth's natural reparative response.
The horse's tooth is very different from a human tooth, but the fundamental concept is worth understanding:
The living tissue inside the tooth matters.
And once we have removed too much tooth, we cannot simply put it back.
๐๐ก๐ ๐๐จ๐ฅ๐ฅ.
We also need to look beyond the โpoll.โ
A horse that continually develops poll tension, resists flexion, or repeatedly appears to need a poll adjustment may have contributing factors elsewhere.
Trauma, training, riding, muscular and fascial restrictions, cervical dysfunction, dental imbalance, TMJ dysfunction, and other factors can all contribute to how a horse carries and moves its head and neck.
From an osteopathic perspective, the question should not simply be:
โWhere is the tension?โ
It should be:
โWhy is the tension there, and why does it keep returning?โ
If we continually adjust the poll without asking why the tension keeps returning, we may be managing an expression of the problem rather than understanding the larger pattern.
Sometimes the answer isn't another adjustment.
It isn't another float.
It is time.
Time for the tooth to erupt.
Time for the tissues to adapt.
Time to address the body.
Time to reassess.
Because good dentistry isn't always about knowing what to take away.
Sometimes the most important thing we can do is recognize what needs to remain.
