* Incisors: These are the front teeth used for biting and tearing. Foals have 12 deciduous incisors, and they lose them in pairs, starting with the central incisors (also known as the "central nippers").
* Canines: These are the pointed teeth located behind the incisors. Foals have 4 deciduous canines, but they don't usually erupt until the foal is about 6 months old and are not shed.
* Premolars: These are the teeth located in the back of the mouth, used for chewing and grinding. Foals have 12 deciduous premolars, and they lose them in pairs, starting with the first premolars.
Here's the typical order of tooth loss for a foal:
1. Central incisors: Around 6-8 months old.
2. Intermediate incisors: Around 10-12 months old.
3. Corner incisors: Around 18-24 months old.
4. First premolars: Around 24-30 months old.
5. Second premolars: Around 30-36 months old.
This is just a general guideline, as some foals may lose teeth slightly earlier or later. It's important to note that foals do not lose their canines. Their deciduous canines are eventually replaced by adult canines.
By observing the pattern of tooth loss, you can get a good idea of a foal's age. Veterinarians and horse owners use these "tooth charts" to estimate the age of horses.
