A human tooth can be seen in babies as early as three months. It usually takes a few days for these teeth to grow and come in fully. A child should have their first set of teeth by the time they are a couple of years old.
For your child's two front teeth to grow back, it will likely take about a month. This depends on how close the teeth are to growing in, though.
it takes about a month, give or take a week, for there teeth to come in.
The upper "front teeth" usually "come out" around 7-8 years old
How long it takes a little bit of alopecia to grow back varies depending on the person. It can take days to weeks to grow back.
They always grow back,silly!!:)
If it is your baby molars fell out, then they will grow back.
That would depend on if your a child or not. you have two sets of teeth in your life time, when you are a child and lose a tooth an adult tooth takes its place, if your an adult and lose a tooth it does not grow back.
It takes about a month for a news layer to grow back
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.
About a month
