Dr. Joe has the best answer.  \nHe is definitely ready to take the national boards\nattention to detail Ha\n\nchoose his. \nNice.\n\nSorry Tweetie Bird there are only 20 Deciduous teeth total

If you're referring to a human skeleton, yes, a good approximation can be done because our teeth have limited growth (they're brachydont) and we only have 2 generations, like most mammals. Therefore, an expert could see if the teeth are part of the milk or definitive dentition, and also assess the wear of the occlusal (grinding) surfaces. And not only the external appearance of the teeth is examined, but also the tissues (dentine, cement, enamel, pulp cavity).\nThere are standards to calculate age and they're normally used by forensic experts.\nA list of bibliography on the subject:\nhttp://users.breathe.com/malt/agedet.htm\nI've tried to find articles but none are free :-(\n\nHowever, other mammals have permanently-growing teeth, and therefore age determination is more difficult. And in other vertebrates that have more dental generations, other methods are used for age determination.

I'm a genetic anomoly.  I've lost particular teeth two and three times and had hem grow back.  I had some extra teeth.  Even now, at the age of 28 and with all my adult teeth fully surfaced, I have seen in my X-rays a nascent incissor in my skull--and that's a tooth I've lost twice already.\n\nNormal people only get to lose their baby teeth once, but freaks like me have extra sets of teeth.

Well compared to a humans lifespan we are only baby's for a short period of time.  After a certain age we need stronger teeth(adult teeth) to help digest all of the harsher stuff we eat as adults for the rest of our lives.  Some individuals such as myself have been blessed with extra teeth (3rd) a condition called freakishly "shark teeth" (because shark have 3 sets) that are still in my gums waiting for me to loss the tooth above it to come up. I am over 20, lost a tooth recently and the 3rd one came up! Cool for me!

206.\n\nAt birth the human body has about 350 bones, but by the time adulthood rolls around, some of our bones have fused together to give us a total of 206 bones in our body!\n\n28 skull bones\n\nthe horseshoe-shaped hyoid bone of the neck; \n\n26 vertebrae\n\n24 ribs plus the sternum or breastbone(2 clavicles, the most frequently fractured bone in the body, and 2 scapulae)\n\n the pelvic girdle (2 fused bones); \n\n30 bones in our arms and legs (a total of 120); \n\nThere are also a few partial bones, ranging from 8-18 in number, which are related to joints.\n\nBasically, there are 7 vertebrae and the hyoid bone in the neck.

There ae 32 teeth in the adult dentition.  There are 4 quadrants in the mouth with 8 teeth in each quadrant.  From the front of the mouth going back, the names of the teeth are:  Central Incisor, Lateral Incisor, Cuspid (Canine), 1st Bicuspid (1st Premolar), 2nd Bicuspid (2nd Premolar), 1st Molar, 2nd Molar, 3rd Molar (Wisdom Tooth).\n\nNot everyone develops all of their teeth so they may or may not have 32.  Also, it's possible to have an extra tooth, known as a supernumerary tooth, so there may be more than 32.

There are 206 bones in the human body.

In a single hand, there are 5 phalanges, and 5 meta phalanges. \n\nI hope this helps!

A child normally loses it`s teeth in the following ascending order--\n(1) lower front 2 teeth (central incisors)\n(2) upper central incisors + lower lateral incisors(ones beside the centrals)\n(3) upper lateral incisors\n(4) lower canines(next to the laterals)\n(5) upper 1st molars\n(6) lower 1st molars + upper 2nd molars\n(7) lower 2nd molars + upper canines

OH, you mean CANINE TEETH.\n\nSpelling is important if you wish to be understood child.\n\nFirst off snakes don't have canines. Most mammals do have canines, including humans.\n\nCanines are the elongated, sharply pointed teeth near the front of the jaw. They are commonly called fangs although that name is incorrect since fangs are hollow teeth and canines are always solid.\n\nCanines are designed to allow predatory animals to grasp prey. They are sharp so they can puncture skin and muscle when the animal bites, and they are long so that when they go in they won't slip out until the animal opens its jaw.\n\nSome herbivorous animals also retain their canines from their more carnivorous ancestors. The largest canines belong to the African hippopotamus, and although hippos are vegetarians their canines are over a foot and half in length. Hippos use their canines for fighting other hippos rather than for catching prey.\n\nCelbone canines are not used for tearing. They are used for gripping. The incisors and premolars and incisors are used for tearing.

The flat teeth near the back of your mouth indicated that you crush things such as leaves (lettuce), the sharp-pointy teeth near the front indicate that your teeth were designed to eat meat (pork-chops...yum). Therefore human teeth represent an omnivorous animal.

The temporomandibular joints (TMJ) connect the lower jaw, or mandible, to the temporal bones at the sides of the head. These joints are flexible, allowing the jaw to move smoothly up and down and side to side, and enabling us to talk, chew, and yawn. TMJ dysfunction involves face pain, clicking sounds in the TMJ, and limited movement of the jaw. About 33 percent of the population has TMJ dysfunction, and as many as 75 percent have some symptoms.

How many is a lot?  I can come up with a statistical average, but it would be meaningless.  I have some 37 year old patients who only have one or two fillings and some who only have one or two TEETH.  Somewhere in between that amount...\n\nThese days, I'd say it's common to see someone that age with maybe 8-to-10 fillings and zero-to-one crown.  The crown would be on a tooth that was decaying just as the young adult moved from home and decided to put dental care on the back burner.  Unfortunately, THIS tooth decayed all the way to the nerve and needed root canal treatment followed by a crown.\n\n§

Vertebrae. Cervical vertebrae, to be precise. All mammals have seven, including humans.

Domestic dogs have 42 teeth, as do wild dogs in the genus Canis.  The bat eared fox has 52 teeth, but some wild dogs have less than 40.  The names are the same as they are for all mammals:  molars, premolars, canines and incisors.  The 4th upper premolar and 1st lower molar compromise the carnassial "scissors" that enable carnivores to slice up flesh.

Well, yea and no..Only vertebrates have teeth as we know them, but insects, including caterpillars, do have structures called "teeth". \n\nCaterpillar mouthparts are mandibles, which are the mouthparts of all the arthropods - by far the largest and most successful animal group, which includes insects, crustaceans, spiders and relatives, millipedes, centipedes and a few more slightly obscure groups of things.
