stallion
adult male horse of breeding age
gelding
castrated male horse
mare

deciduous teeth
temporary, milk, or baby teeth
permanent
second eruption or adult teeth
eruption
pertains to the period when breaks through the gum
labial surface
surface towards the lips
lingual surface
surface towards the tongue
buccal surface
cheek surface
1st incisor
central
2nd incisor
intermediate
3rd incisor
corner
canines
develop around 4-5 years of age, top and bottom, and located within the middle bars of the mouth
P1
first premolar, known as wolf teeth, which don’t appear until 5-6 months of age, only on the top, located directly in front of premolars, often removed at early age
P2, P3, P4
2nd, 3rd, 4th premolars, cheek teeth, deciduous and permanent teeth
M1,M2,M3
1st, 2nd, 3rd molars, permanent only, no deciduous
teeth formula
2(I 3/3 C 1/1 P 3-4/3 M 3/3)= 40-42 teeth
diastema
space between two teeth, where the bit goes
foal eruption times
Di1: 6 days (birth or first week)
Di2: 6 weeks (4-6 weeks)
Di3: 6 months (6-9 months)
Dp2, Dp3, Dp4: birth or first 2 weeks
young horses-permanent incisors eruption times
central pair: 2 1/2 years
intermediate: 3 1/2 years
adult corner incisors: 4 1/2 years
5 years: fully developed
dental table
the table, masticatory or occlusal surface, where the upper and lower teeth touch
infundibulum
the deep funnel of enamel filled with a variable amount of cement
cup
the dark cavity of the infundibulum
dental star
darker dentin that fills the pulp cavity as the tooth wears, slightly visible at age 5 and very visible by age 8
galvayne’s groove
the longitudinal depression on the labial surface of the upper corner incisor
cups
hollow and rectangular or oval in shape, appearing on the tables of the permanent incisors, that wear away over time
smooth mouthed
what the horse is referred to when all the cups are gone, average age is 11-12 (up to 15)
angle of incidence
angle and shape of the incisors: as horse ages, angle of incisors becomes more acute, slanting forward
parrot mouth
lower jaw too short
monkey mouth
lower jaw too long
dental points
dental problem where the top is wider than the bottom and can result in sharp points that can cut cheeks
floating
treatment for dental points that involves filing off the sharp points
hooks
formed when the front border of the upper 1st teeth are further forward than the lower 1st teeth, can cut into the gums
four key changes to estimate age
- occurrence of permanent teeth
- disappearance of cups
- angle of incidence
- shape of the surface of the teeth
