Generally what we use in the dental clinic is a tooth whitening agent that has got a particular agent that whitens the tooth. Buy in lemon or baking soda, this particular agent that whitens the tooth is not present. So scientifically it does not penetrate the tooth or the entire teeth. So it will not be really useful to use lemon or baking soda. Rather ask a dentist what it is and only then it is better to use any kind of home remedy for the problem.
