They do look like gum and teeth but it would be helpful if you can tell us where you are going with this. If its for a monster, toony character etc.
My biggest issue is the transparency on the teeth.
That looks very nice, but can you render it with HDRI lightning? It’s hard to imagine them with only single source of light in a plain gray scene.
True, forgot about that. Currently im too focused in finishing the scene entirely
It will be used on a human mouth but with a weird twist. The teeth have two layers,the enamel on the outside which is partially transparent and the dentin on the inside.
