0 one of the large teeth at the back of the mouth in humans and some other animals used for crushing and chewing food -- 臼齒，磨牙
1 containing one mole of a substance in each litre of a liquid -- 體積莫耳濃度的（在一升溶液中含有一莫耳溶質的）
The most common teeth affected are mandibular (lower) canines, premolars, and molars, especially third molars.
The incisors are very small, the canines large, and the molars are tricuspid.
Entelodonts had full sets of teeth, including large canines, heavy incisors, and relatively simple, yet powerful, molars.
They have incisors, premolars and molars, therefore lacking canines.
The dentition is complete with strong, procumbent, chisel-shaped incisors, strong sharp-pointed canines, and low-crowned cheek teeth with bilophodont molars.
Incisors are used for cutting or biting off pieces of food; canines, are used for tearing, premolars and molars for chewing and grinding.
To my certain knowledge, they have taken three bites at the cherry, and have cracked their molars every time.
I understand that the point about six months is that, roughly speaking, that is the time at which a puppy gets its first molars.
