If you’re looking for a teeth whitening remedy without coming to the dentist, there are a few simple things you can try at home like brushing with baking soda or using hydrogen peroxide to brush or rinse with on an occasional basis. 1. Cut the peroxide in half so you are using a 1.5% solution and not a 3% solution, which is common for over-the-counter. 2. Use apple cider vinegar as a brushing or rinsing agent. 3. Eat more fruits and vegetables as they are good for your body and your teeth. 3. Limit your consumption of foods that stain your teeth such as soda, coffee and red wine. 4. Limit your sugar intake and always remember to brush and floss twice a day—it’s still a powerful tool.
