Dental Disease in Horses
Sharp enamel points, diseased teeth and uneven wear can cause pain, weight loss and poor chewing, especially as horses age.
THE SHORT VERSION
Understanding supports better veterinary conversations.
Sharp enamel points, diseased teeth and uneven wear can cause pain, weight loss and poor chewing, especially as horses age. The same outward signs can occur with several diseases, so an examination and appropriately selected testing are important.
What is this condition?
Sharp enamel points, diseased teeth and uneven wear can cause pain, weight loss and poor chewing, especially as horses age. The same outward signs can occur with several diseases, so an examination and appropriately selected testing are important.
Which animals can be affected?
Risk factors, examination findings and management can differ between species and individual patients.
Why can it happen?
- Normal tooth wear becoming uneven, fractured or infected teeth and periodontal disease.
- Age, jaw alignment and missing teeth affect chewing surfaces.
What might an owner notice?
- Dropping partially chewed feed, slow eating or quidding.
- Weight loss, foul odor, facial swelling, nasal discharge or resistance to the bit.
How is the problem investigated?
- Sedated oral examination with a full-mouth speculum and good lighting.
- Dental radiographs or other imaging when root disease or fracture is suspected.
What might treatment involve?
- Appropriate floating and treatment or removal of diseased teeth.
- Individual feeding adjustments for impaired chewing.
This is an overview, not a prescription or a recommendation for a specific individual animal.
What can owners do at home?
- Write down when the problem began and track appetite, drinking, waste, activity, breathing and medication use.
- Bring clear photos or short videos when they can be taken without stressing the animal.
- Follow the veterinary team's instructions for medication, feeding, isolation, environmental changes and rechecks.
Avoid actions that could make care less safe.
- Do not use human medication, leftover antibiotics or another animal's treatment without veterinary direction.
- Do not force food or water into an animal that cannot swallow normally, is struggling to breathe or may have an obstruction.
- Do not delay veterinary care when pain, breathing, appetite, urination, movement or responsiveness changes quickly.
What can the longer-term outlook involve?
The outlook depends on the underlying cause, severity, species and how quickly effective care begins.
Can risk be reduced?
- Provide species-appropriate nutrition, housing, sanitation and routine veterinary care.
- Learn the animal's normal behavior, appetite, body condition and waste pattern so meaningful changes are noticed early.
When should you arrange care?
- Contact a veterinarian promptly for dropping partially chewed feed, slow eating or quidding. or weight loss, foul odor, facial swelling, nasal discharge or resistance to the bit..
- Arrange reassessment if signs return, worsen or do not improve as expected.
Seek emergency veterinary care if you notice:
