YANBU - DS1 once had a wobbly one for six months, it was really wobbly but just never came out. In the end the dentist pulled it out.
He has just yesterday been told by the orthodontist to get wobbling his last two milk teeth so that they can start on his braces. If they're not out in three months the dentist will have to pull them out. He's wobbling furiously!!
Good luck, hope yours come out quicker than DS's!!
DS had a loose front tooth for about two weeks. We were away on holiday with my parents (so he was eating loads of holiday 'rubbish' then went to my parents' house) While he was eating garlic bread it came out.He blamed me for putting a stone in his garlic bread Then two of his bottom teeth popped out on the drive home.
My older DB told me to do what he did, but i was too scared so he did it. Tied a piece of cotton thread < mum always had loads as made all our clothes> round the tooth to the open door knob and then he shut the door quick.
