There are a lot of theories based around the management of horses during the ages of permanent tooth eruption (2.5yo-4.5yo).
Many people underestimate the importance of regular dental visits, often having the view that ‘nature will take its course’.
The problem with this is horses have hypsodont dentition, meaning they continue to erupt reserve crown throughout their life, making them susceptible to irregular wear and malocclusion.
Retained caps are a contributing factor to irregular wear, so if you have a young horse be sure to have them looked at on a regular basis, setting them up for the future. Prevention is better that cure.
