Articifical capped tooth question

[jdawsy]

Hi all ,

A few months ago I had an accident whilst playing rugby where my central incisor got chipped. I had it repaired and although I am not sure what material the artificial add on is now , in photos it is clearly visible as it comes out as what looks to be slightly stained /or the light passes through it or something . It's quite hard to explain . I was just wondering , though what sort of care and attention I need to give to make the articifical cap on look more white and natural and not as artifical as it looks.

Hope this makes sense.

Thanks
