Iguanodontid material is common in the UK Wealden, but juvenile material is always nice to find. This looks to be a dentary tooth, based on the broad diamond shape. For comparison, here's a photo of a medium-sized adult dentary tooth from Iguanodon bernissartensis:

A few weeks ago: The best Iguanodon fossilA few weeks ago (on my Facebook page), I posted this photo of another juvenile Iguanodon bone. It's a tiny thumb spike! The spike is a little bit worn as it has been rolling around the beach for a while, but you can see the "nail groove" running down the side.
When I found this back in the 1990's, I was not particularly experienced in identifying bones, so for a while I thought it was a crocodile tooth, but it is clearly bone.
