It freaked him out when it became loose. He didn't dare to ride his bike as he was afraid that it would fall on to the ground and neither did he dare to eat as he might swallow it. It was a couple of days before he felt comfortable with it.
Fast forward another 3 days and the tooth has fallen out. Good thing it happened after he finished his dinner. He was enjoying his fruit when it decided to come out. That got him off eating as it felt really weird.
It happened when we were at my parents' place and he's staying the night there, so I guess the tooth fairy will be dropping by their place tonight :)
