I've just been Daniel of every dental

specialist in Chilliwack British Columbia this is trooper and his owner joking I have a series of videos called dentistry for pet owners on YouTube there to help you look after your pets teeth and show you how to recognize problems in the mouth so that you can tell your vet so trooper do you wanna help us okay so what I want you to start doing if you're not doing this already is with your pets start looking at their teeth all right now trooper is totally used to this and you just lift the lip and see how I'm lifting the look to show the upper and lower molars and fourth premolar troop is very good some dogs won't be quite so good so make sure that you're careful and you don't get bit thank you that is lovely okay that's good hello I'm Joseph Emmanuel David I'm a veterinary dental specialist in Chilliwack British Columbia and I'm here to talk to you about the general anatomy of the head of the dog this is a plastic dog skull and the clear plastic represents the bones of the skull and the white structures are the teeth there are four jaws in the head of a dog and

this is the upper right lower right upper left lower left doors when we talk about the teeth we start at the midline when we number them and that's the midline and this is incisor one two and three this is the upper canine and the upper four premolars one two three and four this is a large - the last four the fourth premotor is a large tooth and then you've got the upper molars one and two when you look at the lower jaw you've got in sizes one two and three the canine and in premolars one two three and four and the lower molar teeth one two and three and the lower molar is a very large tooth the purposes of the teeth are for the incisors they are used for grooming display and for holding small things the canine teeth are to catch the prey and to hold them the premolars are to cut through the meat of the of the prey and the molar teeth are to crush the food to chew it if you look at this model you can see the surfaces of the crowns the premolars of the top jaw are sharp and the chewing surface of the molars are nice and flat so they're really good for chewing again on the bottom jaw the all of the premolars and the front part of the

first molar have a sharp crown and the back part of the first molar and the second and third molar are flat so they're good crushing surfaces so when you are counting your teeth you want to make sure that you count the total upper lower right upper lower left and add them all together and in the adult dog you should have 42 teeth I want to point out a couple of things about the teeth the length of the tooth is very long what you see in the mouth which is a started about here starts at the gum line that's called the crown and that's about a third of the length of this the tooth 2/3 of the total length are actually in the bone so in the incisors that's where they end they're very long the canine tooth see where it ends that represents 2/3 of the total length of the tooth there's the third that you do see and the same goes for your premolars and molars they have very long roots also the number of roots per tooth changes the incisors have one root the canines have one root the premolars have one root the first premolars do and the lower third molar has one root when you look at the second and third upper premolars and the second third

and forth lower premolars and first and second lower molars you'll see that they have two roots the upper fourth premolar and the first and second upper molars have three roots what that means is that when you have long roots and you have several roots for tooth you have more work for your vet when it comes to extractions thanks for watching
