It is most likely decay, but it could be something else. The only way to know is to see a dentist. The brown spot is most likey not caused by antibiotics. Those type should not be given anymore. And they normally affect the adult teeth and all of them, not just one. It is possible that it's decay and will need to be filled. If it is decay, then their are probably other teeth that have decay also. A front tooth usually gets a cavity after the back teeth. But if the child goes to bed with a bottle or cup or even on the breast a lot, it could be decay from that. The only thing in a bottle that won't cause a cavity it plain water. Juice, milk, formula, breast milk; all of that may cause a cavity. Bottom line, the child should be taken to a dentist to be sure if it is or isn't and fixed if it is.

I once had a cat who had brown discoloration on his teeth, and the vet told me that was because he had probably been given tetracycline as a kitten, before I got him.
