Extra baby tooth??

DS had a dentist appointment on the weekend, to check on what I assumed to be an adult tooth coming through behind his baby tooth, at the front.

The dentist looked and said 'I don't think it's an adult tooth, let's do an xray.'

Turns out he has an extra baby tooth at the front.

The adult teeth are there and look fine but there's three front teeth not two. The dentist seems happy enough to leave things as they are but DH wants one of them removed as he thinks it looks weird and is worried about DS getting teased at school.

It does seem to be affecting his speech a little but I think it's only me who's noticed it.

What would you do? I don't think they could easily remove the extra tooth, they'd need to remove the existing on and let this new one grow in it's place
