My son Ethan was in year 2 before he lost his first tooth.. It was wobbly for months, yet all the other teeth have wobbled for a day or 2 then fallen out.. So just a year after his first tooth fell out we are now up to 5 and another 2 wobbling. Also big teeth at the back just started coming in..

As for growing back Ethans first couple of teeth grew back within a week or 2 yet his 2 front teeth are still empty even 3 months later

My nephew had a wobbly tooth and lost it the next day. He is only 5 and a bit..
