Study Notes
Incisors
- Each dental arch contains four incisors, totaling eight incisors for the entire mouth.
- Incisors are located at the front of the mouth and are the first teeth to emerge.
Canines (Cuspids)
- Canines are the pointed teeth located next to the incisors, with one in each quadrant of the mouth.
- Their primary function is to tear food, aiding in the chewing process.
Premolars
- Each dental arch has two premolars, leading to four premolars total in the mouth.
- Premolars have a flat biting surface designed for crushing and grinding food.
1st Molar
- The first molar is classified as the first large tooth behind the premolars, usually the upper first molar is known as the "upside-down Y" shape.
- These teeth are essential for grinding food due to their flat surfaces.
Tooth Arrangement
- Teeth are arranged in the oral cavity in two dental arches: the upper (maxillary) and lower (mandibular).
- Each arch consists of incisors, canines, premolars, and molars, facilitating various functions in eating and speech.
