How to remove an object (Tooth) in After Effects I have a 5 second Video clip of our main Character smiling and when he opens his mouth we see that his tooth is gone. We have painted the whole tooth black but there is a shine on it and it doesn't look right. You can see that the hole up to his gum is black and probably should probably be more red.The shot itself is static.  

I was wondering how to remove this tooth in after effects. Its the final shot of the film so is important to get right. I have after Effects CS5.5 and Motion. 

If necessary we would shoot it again if anyone has any tips. Thanks! 

Thanks everyone that replied. Sorry for the delay in getting back. We had a bereavement in the family and everything was left. I think Rotoscoping is the way to go. Will update when i fix the problem.
Unfortunately, the only answer is rotoscoping.  You have to remove the tooth from each frame manually.  Rotoscoping tools will help give a closer starting point, but that kind of object removal where both the object and the background behind it are changing and moving is nearly impossible to do without manual effort.

Note, if everything in the mouth behind the teeth is black or basically the same color, then you have a lot more options as Brett outlined in his answer.  I was assuming that there was more detail in the mouth based on your description that would require background painting, but if you can avoid background painting for the mouth, then rotoscoping isn't needed.
