Incisors
Incisors are the front teeth
Humans have 8 incisor teeth
They have 4 at the top and 4 at the bottom
Incisors are made for tearing food – like when eating a chicken leg
Canines
Canines are the longer pointy teeth Humans have 4 canines 2 on the top and 2 on the bottom They help the incisors to tear food by
firmly holding the food in place Eruption of the canine teeth normally
happens between 11 years old and 12 years old
Pre-molars
Premolar teeth are found between the canines and molar teeth
Humans have 8 premolar teeth 4 at the top and 4 at the bottom Premolars are used to chew food. Another
word for chewing is mastication
Molars
Molars are the teeth that are furthest back in the mouth
Humans have 12 molar teeth Molar teeth are in sets of three with 6 in
the top and 6 in the bottom The farthest back molar is called the
wisdom tooth Molars are for grinding food after it has
been chewed
Wisdom teeth
Wisdom teeth normally appear between 17 years old and 25 years old
Most adults have 4 wisdom teeth Sometimes wisdom teeth effect other
teeth as they develop because they ‘impact’ on them. This means they grow sideways and push against the other teeth which can hurt. If this happens sometimes they need to be taken out and this can happen in hospital

How to keep your teeth healthy
Eat foods that are low in sugar like vegetables, cereals, nuts and fruit (even though fruits have their own sugars inside)
Drink lots of milk and eat plenty of diary products like cheese and yogurts because they have calcium and vitamin C which helps make strong teeth
Brush your teeth twice a day for 2 minutes each time
Thanks for watching!
