In humans, we only get two sets of teeth. Children have what are known as milk teeth and these fall out, or are knocked out accidentally. We then get our adult teeth.
In some other species - such as sharks, the teeth are continuously renewed.
Once a person is past childhood, adult teeth do not "grow back" once they've been extracted (pulled out).
you can get two teeth your primary "baby: teeth and your permanent "adult" teeth. when you lose you adult teeth it will not grow back
Adult wolf teeth do not grow back. In fact, teeth do not regenerate in any mammal once they have reached adulthood.
Once you have replaced your baby teeth with adult teeth, if you lose one it is gone for good.
once a cavity is formed in the teeth the teeth doesn't have the capacity to repair itself .but we can fill the cavity artificially
Baby teeth will never grow back, once their gone their gone. However, this 4 year old may have earlier adult teeth. These are stronger, but take care of them. For when these Adult teeth are gone, theres no way of getting them back, unless of course you wear dentures or have teeth implants. This however is very expensive, and as a 4 year old, i wouldn't want to be wearing dentures!! So the answer to your question is that, his baby teeth will never grow back, but his Adult teeth will.
All baby teeth are deciduous (they fall out) and do not grow back. However, after they fall out, they are typically replaced by the permanent "adult" teeth. Sometimes, though, the baby teeth don't fall out. And sometimes, the adult teeth don't grow in. But "normally" a child will lose all their teeth and they will be replaced by their permanent teeth.
Ummmmm....... FYI Once you lose your adult teeth you need dentures (aka false teeth) you don't get another set of teeth.
Yes, when children lose their first/'Milk' teeth they grow new teeth. Sometimes they all grow at once and get crammed up in their Mouth's they'll need braces, eventually - when they've lost around about all of their 'Milk' teeth they'll grow rather large molars at the back.
GENERALLY, once wisdom teeth are gone they don't grow in again. If something is coming out from your gums after a wisdom tooth extraction, it might be a piece of root that was left out. It might also be a surnumerary wisdom tooth (extra wisdom tooth) that was already there before the extraction. However, they can grow back. It's documented, and happens to 1-3% of adults.Teeth don't grow back. Basically you get two sets, first the baby/milk teeth, then your permanent teeth. Wisdom teeth are the last of your permanent teeth to emerge.If you lose a milk tooth it will kinda-sorta be replaced with a permanent tooth (which you would have gotten eventually anyhow).When a permanent tooth is lost it's gone, your body won't make a new one.Back teeth are also known as molars. If you lose one of those before you have gotten your wisdom teeth, then it can look like it's the lost one that's grown back, but it isn't. It's the wisdom tooth (which you would have gotten eventually anyway) that has stepped up in its place.No. they dont grow back once they are removed. however, rarely we do find an extra molar, other than the wisdom teeth, which are called as the PARA Molars.Teeth don't grow back. Basically you get two sets, first the baby/milk teeth, then your permanent teeth. Wisdom teeth are the last of your permanent teeth to emerge. When a permanent tooth is lost it's gone, your body won't make a new one.
you just can't. once it's gone, it's gone. so always brish and floss ur teeth kids!
Dogs have similar teeth development to humans - they have one set of deciduous ("baby") teeth and a second set of permanent ("adult") teeth. However, once their permanent teeth come in, there are no replacements for them.
