6 months 4 more come in, 2 upper and 2 lower , corner incisors
6 months the 2 wolf teeth erupt (its possible to have none to 4 wolf teeth in varying positions)
The
last Permanent teeth come in at 2 , 3, and 4. The last 12 molars
that come in, never have caps, only come in as permanent teeth
At 2 1/2 ~ the youngsters get their first permanent teeth, 4 molars and 4 incisors ( losing their caps.)
The
permanent tooth is 3 inches long in total. The whole permanent tooth
erupts from upper and lower jaw bone. They are not down completely
until 3 years of age. This is a 6 month process to break through gum.
Also the four incisors caps come out over the next 6 months until they
are in wear.
At 3 years old ~ the next molar caps come off and it's another 6 months until the new teeth are in wear.
At 3 1/2
~ the 3 molars come in and start to line up. They also lose 4 caps and
it is another 6 months until those teeth start to wear.
At 4 1/2 ~ 4 incisors caps come off and permanent teeth erupt.
Then the last three molars in upper and lower come in ,( total of 6) and they are
perment teeth, never having caps . This makes the 4 th molar the oldest tooth in the mouth and
we look for the wear in older horses.
At 5 yrs ~ all permanent teeth are in and mouth is ready to "go to work" with bit, etc.
So in summary:
At 2 1/2 - 8 permanent teeth are coming in
At 3 yrs - 4 molars coming in
At 3 1/2 - 8 permanent teeth , 4 molars and 4 incisors, are coming in
At 4 yrs - 4 more molars come in
At 4 1/2 - 4 remaining incisors come in
At 5 all teeth in and starting to wear if everything is balanced.
The most crucial time in a horses mouth is
when many trainers are starting youngsters from 2 to 4 1/2 yeas old .
The bit is most
painful until they are 3, but the whole mouth is in this tooth process
until they are 5. The bumps under the jowl are the teeth trying to cut
through the gum to come up and knock out the caps.
Equine dentistry is extremely
important, especially for the young horse being started with a bit. So
make sure you and your trainer are observing your youngster and taking
care of their teeth during this time period.
