Dental Welfare in Aging Horses: Meeting Complex Needs

Dental problems are the most common health issue affecting horses over 20 years old. Understanding age-related dental changes is essential for maintaining quality of life in geriatric horses.

Key Facts

Horses have hypsodont teeth that erupt throughout life and are gradually worn down by grazing
By 25-30 years of age, horses often have severely worn teeth unable to process roughage adequately
Periodontal disease, loose teeth and gaps in the dental arcade are all common in horses over 20
Horses with dental problems lose body condition, change feed preferences and show reduced hay intake
Regular dental examination every 6-12 months is recommended for all horses, with increasing frequency in older animals

Welfare Considerations

Dental pain in horses is often chronic and underrecognised. Horses rarely vocalise pain and may continue eating despite significant dental discomfort, masking the welfare problem from owners. Weight loss, head tossing, bit resistance and dropping partially chewed feed (quidding) are observable signs that dental pain is affecting welfare and behaviour. In older horses, the progressive loss of functional dental surface means that even with regular veterinary care, nutritional management must adapt to declining dental capacity. Horses unable to maintain body condition on hay may require soaked hay cubes, fibre pellets or other easily processed alternatives to prevent slow starvation.

What You Can Do

Schedule dental examinations every 6 months for horses over 15 years of age
Learn to monitor body condition score monthly and seek veterinary advice if score falls below 4/9
Adapt the diet of horses with severe dental wear to include easily processed fibre sources
Work with an equine dentist or veterinarian to develop a dental health plan for geriatric horses
Ensure older horses have adequate time and space at the feed face without competition from younger animals
