What number on your upper and lower incisors
uppper 8&9, Lower 25 & 26
What numbers are you upper and lower canine?
11, 6, 22, 27
Central How many Roots?
The two upper and two lower teeth in the very center of your mouth. Single Rooted
Lateral, how many roots?
The teeth just adjacent to the centrals. Single rooted
Cuspid, How many roots?
The pointy teeth just behind the laterals. These teeth have one cuspal (or point). Cuspids are also called canines. Single rooted
First Bicuspid (pre-molar) How many cuspals and how many roots?
The teeth just behind the cuspids. These teeth have two cuspals (or points). It is Bi-rooted on maxillary, single rooted on mandible.
Second Bicuspid (pre-molar) How many cuspals and how many roots?
The teeth just behind the first bicuspids. These teeth also have two cuspals (or points). Single rooted on maxillary and Mandible.
First Molar How many roots?
The teeth just behind the second bicuspids. These teeth have a level surface with four cuspals. Tri-rooted on maxillary, bi-rooted on mandible
Second Molar How many roots?
The teeth just behind the first. These teeth also have a level surface with four cuspals. Tri-rooted on maxillary, bi-rooted on mandible
Third Molar How many roots?
The teeth just behind the second molars. These teeth also have a level surface with four cuspals. Tri-rooted on maxillary, bi-rooted on mandible
Incisor
Another name for the centrals and laterals
Canine
Another name for the cuspids
6 year molar
Another name for your first molar
12 year molar
Another name for your second molar
Wisdom Tooth
Another name for the third molar
Anterior Teeth
Your centrals, laterals, and cuspids. These are the teeth in the front of your mouth
Posterior Teeth
Your bicuspids and molars. These are the teeth in the back of your mouth.
Deciduous Teeth
Your primary, or “baby teeth”
Primary teeth
The first set of teeth which come in. Primary teeth are also called “baby teeth” or deciduous teeth.
Secondary Teeth
Your permenant teeth, i.e. the second group of teeth to come in.
Quadrants
The four parts of your mouth, that is the upper left, the upper right, the lower left, and the lower right.
Numerical notation for teeth
The numerical notation for teeth is an alternate to Palmer’s notation. In this notation, the centrals are designated as 1’s, the laterals as 2’s, the cuspids as 3’s, the first bicuspids as 4’s, the seond bicuspid’s as 5’s, etc.
Universal numerical notation for teeth
The universal numerical notation is an alternative numerical notation for teeth. In this notation, your upper right third molar is designated as tooth#1, and then you number each tooth sequentially moving right to left and down across your mouth.
How many molars does an average mouth have in each quad?
3 1st Molar 2nd Molar 3rd Molar
How many pre-molars or Bi-cuspid does an average mouth have in each quad?
2 1st bicuspid 2nd bicuspid
What teeth are considered posterior?
Molars and Pre-molars
What teeth are considered anterior?
Incisor and canine (cuspid)
Incisor
cutting, straight edge Front teeth, Chisel shaped for cutting
What tooth is this?
Incisor
What tooth is this?
Canine
Canine
One cuspid, pierce and hold, pear shaped, pointed, convex, incisal

What teeth are crushing and Grinding?
Molars
What are the position, shape and # of cusps of molars?
Maxillary premolars and the mandibular first premolars usually have two cusps. Mandibular second premolars frequently have three cusps— one buccal and two lingual. Maxillary molars have two buccal cusps and two lingual cusps.
Shape: The occlusal surface is wide and uneven. Rectangular shape with pits and fissures on it.
Position: Posterior
