After a teeth whitening treatment, you want to avoid certain foods and drinks that can stain your teeth. Examples include red wine, tea, tomato juice, coffee, and soda. You also need to avoid sugary foods, smoking, and chewing tobacco. You shouldn’t take any of these for at least two days after treatment. Subsequently, you should still limit your intake as these substances stain your teeth and can undo the teeth whitening treatment quicker than usual.
On the flip side, you should eat what is known as a white diet in order to guarantee the best results – this includes things like tofu, yoghurt, chicken, fish, etc. Foods that are literally white!
Additionally, you may also want to avoid consuming cold or hot foods a few days after the teeth whitening procedure as your teeth may still be sensitive.
