EOTRH - Dental Disease


Tutorial - First Time Use - Click Here


Chances of Success: Using the Vetdrop System (based on actual work results). Medium to high.


The dental disease EOTRH was long considered untreatable. Treatment with Vetdrop TDA

Older horses from around 15 years of age are particularly affected by the very painful dental disease EOTRH (Equine Odontoclastic Tooth Resorption and Hypercementosis)

There is currently no cure for EOTRH. The disease is becoming more and more common and causes a lot of problems for both the horse and the owner.

No owner wants their horse to lose all of its teeth. There have been some successes with mushroom mixes, but they are limited. However, when combined with Vetdrop, the oxygen and various products, there is a real chance that the day when all teeth need to be extracted will be delayed considerably. The pain is greatly reduced and the carrot test is successful. This can mean your horse can have a full-toothed mouth for years to come, which is probably better for the horse and definitely nicer if the horse has to compete. I think most of us will agree that our own teeth are always better than false teeth or no teeth at all, and we should try to give our beloved animals that opportunity too.

Veterinarian comments on Playboy's case

Yes, I would also find it very interesting, and I am also sure that you could definitely inhibit and reduce the inflammation of the mucous membranes and the progression of the disease. In any case, this brings significant pain relief. However, the problem in the tooth socket remains and so does the resulting pain. Unfortunately it is EOTRH Especially in the advanced stage very, very painful and the pain from the outside not easy or not at all to be recognized (unfortunately, whether the horse is clinically well or it is eating does not say anything). Therefore, the fastest and best option for horse pain relief is total tooth extraction. Based on the photos, it must still be a very painful process because the mucous membrane overgrowth indicates severe hypercementosis in the tooth socket. The horse, provided the molars are nicely balanced, has no problems after a total incisor extraction, except that the tongue protrudes a little. Unfortunately, I can't say more about this at the moment, I haven't seen the case myself. We must therefore leave the decision to the owners, whether they want to put up with longer pain for the horse or whether they want to go for the extraction right away.

In any case, I notice with mine EOTRH Patients only get a clear improvement after removing tartar and shortening the incisors, as well as when the owners regularly brush their teeth and remove food residues afterwards. So there must definitely be an improvement with the vetdrop in my eyes. Especially in the early stages I can imagine that regression and stabilization might even be possible. You should definitely have x-rays in addition to the photos for documentation. I am already convinced that the gums will look significantly better after a few weeks, but the x-ray should show whether there is also an effect in the tooth socket. And if there is a clear improvement there, you can also convince critics of it.


Another comment from a veterinarian who specializes in teeth

He said he doesn't like pulling his teeth if they eat well, are not lean and can bite off carrots, you can definitely wait. He also says it could very well have been tartar that has come off, there are different forms of the disease and some make a lot of tartar above the gums and below the hypercementosis. He thinks that the vetdrop stimulates the body's defenses and the oxygen helps the tissue to regenerate - and therefore the situation is improved. For example, he says that when these horses are stressed or vaccinated (immune system is weakened) one often observes that it gets worse. But when the horses eat well, he waits as long as he can to pull his teeth. (Treatment with Vetdrop TDA)

Playboy and Max needed more treatments - but we had great success. Max lost no teeth and Playboy only lost 2. More information can be found in our treatment journals - EOTRH treatment horse

Equine odontoclastic tooth resorption and hypercementosis EOTRH


  • medical vet Julie Schwechler
  • Dental practice for horses






  • Equine Odontoclastic Tooth Resorption and Hypercementosis EOTRH


  • Painful disease of the gums and gums in older horses (from 15 years)
  • Mainly incisors and stallion teeth affected
  • Increased breakdown of tooth substance (odontoclasts) versus increased formation of dental cement (hypercementosis)


  • Similar diseases:
    • Human: Multiple Idiopathic root resorption MIRR
    • Cat: Feline Odontoclastic Resorptive Lesions FORL



Clinical picture


  • Different characteristics
    • Early stage with slight swelling of the gums and reddish punctiform discoloration of the gums without clinical signs of pain, sometimes increased tartar formation
    • Late stage with massive gingivitis and regression, formation of tooth fistulas and tooth root abscesses with pronounced tartar deposits
      • Significant local sensitivity to pressure, pain when eating food over hay net or biting off carrots, etc.
      • Putrid bad breath, increased salivation, defense against bridle, poor performance, emaciation




  • Clinical symptoms
  • X-rays



X-ray of inconspicuous incisors X-ray of incisors with pronounced EOTRH




  • No secure explanation!
  • Increased pressure and incorrect position of the teeth with decreasing area and strength of the tooth support apparatus in the older horse
  • Circulatory disorders of the periodontium
  • Favoring diseases (PPID (Cushing's disease), calcium deficiency, etc.)
  • Genetically conditioned





  • In the advanced stage: tooth extraction!
    • Individual teeth (mostly outer incisors most affected)
    • Total extraction (protrusion of the tongue as a cosmetic side effect)


  • Tooth correction (pressure relief through grinding, angle adjustment and balancing of the molars)
  • Removal of the tartar
  • Regular manual cleaning of the gum line to reduce bacterial inflammation of the gums
  • Medicinal mushrooms (Equident Matrix, Equimove dental,)



VetDrop as a form of therapy?



  • Anti-inflammatory and antibacterial effect
    • Phyto products (chitosan, urea, turmeric, frankincense extract, panthenol, succinic acid, hyaluronic acid, vitamin E.)
  • Significantly less tartar formation and a decrease in gingivitis
  • Significantly less local pressure sensitivity
  • Positive effect on pathological processes in the tooth support system?
