Baking soda and lemon juice have been touted as great natural, at-home teeth whiteners. But there's no reputable evidence that baking soda and lemon juice really work to whiten teeth, and lemon juice contains acids that could harm your enamel. If you want to brighten your smile, the safest and most effective way to do so is to see your dentist for a bleaching procedure or use one of the over-the-counter tooth whitening products sold in drugstores. Whether you want to have your teeth whitened professionally or you want do it yourself, talk to your dentist first to find out which product is best for you.
American Dental Association answeredWhile baking soda can be used to whiten teeth, it is not recommended. If you are looking for toothpastes that whiten teeth, look for products that contain the American Dental Association Seal. That way you can count on that the products have been evaluated to do what they say on the label. Lemon juice can be harmful to your tooth's enamel and is not recommended for whitening.
Rita Medwid, Dentistry, answeredThere are no known cases of teeth whitening from lemon juice or baking soda. For years, baking soda has been used as toothpaste to brush teeth. The baking soda may remove some surface stains and the teeth may appear brighter. Lemon juice can be harmful to your teeth by causing the enamel to weaken. The teeth may look slicker and shinier, but this is not good for you. The acid erodes the teeth and can make them very sensitive and prone to decay. In time they may get darker looking. The best way to whiten is with over the counter whitening strips or the system the dentist uses.

Baking soda and Lemon juice are not a healthy way to whiten your teeth. Although the result may seem that your teeth are whiter you have actually eroded and abraded your teeth. Lemon juice is very acidic and will erode your teeth. Baking soda is very abrasive and will abrade your teeth. Together they can have a very destructive effect. Once enamel is lost, it is lost forever.
A healthier and more effective way to bleach your teeth is to do the in-office bleaching systems or the at home bleaching systems with bleaching trays. There is no way to know how much improvement you will get but you will see an improvement. Some over-the-counter whitening products can be effective if used as instructed.
A good way to keep your teeth white is to get your routine cleanings, minimize foods that can stain your teeth (coffee, tea, wine, soda etc.) and don't smoke. Also, you can use whitening toothpaste and keep the slurry that forms from brushing in your mouth for about 5 minutes. If done consistently for a few weeks you will notice an improvement.

Baking soda and lemon juice are the equivalent of using Ajax on your bathtub. It gets out the stain but the abrasive nature only makes it easier for stains to return. A healthier way to whiten teeth is to reduce you consumption of acid promoting and corresponding stain producing foods such as refined carbohydrates and sugars. Also some foods can naturally whiten teeth such as those high in fiber such as apples, pears, celery, and almonds. the fiber acts like "tiny toothbrushes" that scrub the surface of the teeth.
