The temporary incisors are all erupted into position by 9 months of age. Foals are checked at or close to birth to determine if any congenital abnormalities exist. Deciduous teeth are soft and can develop sharp edges quickly. From age 2 to 4 months to about 18 months, these teeth should be checked every 4 to 6 months and floated if needed. Floating can be done without a speculum, requiring only three to four strokes of a float per molar arcade to correct.
Permanent premolars begin and are in wear from age two years and six months to age four years.
An eruption timetable is included with these notes. The first molar erupts at one year of age. The last molar erupts into position at age three. These bumps are the developing roots of the permanent third and fourth premolars. The bone of the mandible is remodeling and expanding to allow for the tooth elongation.
