When a child looses their first tooth you should reassure the child that it's a normal and healthy part of growing up.
Once the child begins to lose their tooth you can explain to them that it's normal and there's nothing to worry about.
If the tooth is loose enough they can sometimes gently wiggle the loose tooth enough to allow it to come out.
After the child's tooth falls you there is often some normal bleeding that can be fixed using a clean tissue or gauze and by also maintaining good oral hygiene.
If you want you can also try having the child place the tooth under his or her pillow and let them know that the tooth fairy will leave them some money and in which you yourself would remove the tooth from under the pillow and then place some money in it's place.
Or you could simply keep the child's lost first tooth for a keepsake.
The tooth falling out of the child's mouth ideally should be allowed to fall out naturally as pulling out a loose tooth that is not loose enough could lead to infection or possible damage to the underlying permanent tooth that is gonna replace it.
Also you can encourage the child to wiggle the tooth gently and address any bleeding and clean the area where the tooth was with a soft washcloth or gauze.
When you or a child has a loose tooth it's better to let it eventually fall out instead of pulling it.
However if the loose tooth is loose enough you may be able to wiggle it enough so that it comes loose and comes out.
But as long as the loose tooth is not bothering you or your child it's okay to leave the loose tooth alone and it will eventually fall out on it's own.
Even when kids start to lose their baby teeth the baby teeth start to get loose and then the child can wiggle it.
You can either pull the loose tooth out if loose enough or just wait and allow the loose baby tooth to eventually come loose completely on it's own and fall out.
When I was a kid I would always wiggle my loose tooth until it came out but never actually did any pulling of it.
If the tooth you have is an adult tooth and it's bothering you and causing infections and is loose then you might want to have it pulled but otherwise you can leave the loose tooth alone and it will come out eventually.
A child or yourself won't choke on a loose tooth although it's possible to swallow it in your sleep.
The tooth is small enough that it would simply pass through your throat without any issues but most times you'll wake up when you feel the tooth in your mouth.
