I was looking closely at Stanleys teeth today. Their very clean and bright. However I noticed a build up of dirt between the pairs of incisors on both sides of his top jaw. I used an old tooth brush to remove it best I could but there is still some staining. I'm now going to do this regularly since there is a small bit of decay where the build up was. Does everyone else already brush there dogs teeth? I feel a bit guilty now because had I done it from day one there would no doubt be no decay whatsoever. Your thoughts would be appreciated.
