Reptiles grow new teeth throughout their lives. This is extremely common in reptiles like alligators and crocodiles, who frequently lose their teeth.
Because of the shape of the teeth
Kittens lose their deciduous teeth (baby/kitten teeth) at around 5 to 6 months of age, and the adult canine teeth grow in. Adult cats may lose these teeth due to injury or disease, and new teeth do not grow back.
Fish, amphibians, reptiles (not turtles as they don´t have teeth).
they have sharp teeth
The cards were purchased at the Science Museum in Minneapolis Minnesota, but are probably available on the Internet. Technically the Whale Shark doesn't have teeth.
To let new teeth grow in.
Most reptiles with teeth are able to grow new ones once one was broken. It is surmised that dinosaurs were able to perform this function too.
Yes they do
No, you are born with all your teeth in there, they just shove down after awhile. The roots do grow, but, of course they do.
moulting is when a living thing loses its hair or skin. reptiles do this so they can grow out of their skin and into a new one :)
no
Because of the shape of the teeth
Short, Straight Teeth
Reptiles and fish both regularly replace their teeth. This way they avoid the problems that mammals can get with dental disease. Old teeth are eliminated before they become diseased, and they are replaced by new teeth.
You can not grow a new tooth. All your teeth are present at birth. Your first teeth come in while you are a baby but your second teeth are all ready there as small 'buds" ready to form and come in as you loose the first teeth. As you know, your last teeth do not come in until you are 17-20. Because they come in last and you are older, they are called wisdom teeth.
Your teeth can grow up to 55cm.
Yes, mammals have more teeth that reptiles. The land mammal with the most teeth is the Giant Armadillo (Priodontes giganteus) with as many as 100 teeth. The average range for mammals however is 20-40. Reptiles rarely have many teeth, if any at all. The crocodile has the most, with around 80 teeth at a time. It replaces as many as 3000 in its lifetime, but this is over a long period of time.
