How Teeth Whitening Works?

There are many ways to whiten your teeth, including professional whitening services, over-the-counter teeth-whitening products (e.g. Crest Whitestrips), and natural remedies. The process is especially aimed at the surface stains that come from acidic foods, red wine, coffee smoking, and aging. The whitening substances break down these stains and return the natural color of the enamel layer.
Lemon Is the Most Powerful Teeth Whitener

Lemons contain citric acid, ascorbic acid, and malic acid, all of which have drying properties. These are mildly abrasive compounds that can assist in cleaning the soft debris of food from teeth, giving them a whiter appearance. However, they can also carry risks to tooth enamel and overall oral health.
How Lemon Juice Removes Stains From Teeth
Since lemon juice has a pH level of approximately 2, it is very acidic. This relatively high acid level can aid in breaking down some of the surface stains on your teeth. But constant exposure to acidic ingredients such as lemon juice will wear down teeth, cause sensitivity and, over time, damage the enamel layer.
How to Use Lemon Peel for Teeth Whitening

Some natural remedies even recommend rubbing a lemon peel directly onto the surface of your teeth. The idea is that lauric acid and lemon essential oils in the peel fight bad bacteria — and can lift yellow stains. But it does not seem to have solid scientific backing, and may still erode enamel.
Lemon and Baking Soda
One popular at-home teeth-whitening remedy is the use of lemon juice (citrus acid) with baking soda (sodium bicarbonate). Baking soda is a mild abrasive that can help lift surface stains, and lemon juice boosts the whitening effect. But this mix also has a high acid level, which can erode enamel over time.
Lemon for Teeth Whitening: 7 Potential Risks
True, lemons might give you some immediate color – lightening effects, but they carry serious risks too:
Erosion of teeth – Lemon citric acid can erode the enamel layer of teeth, resulting in increased sensitivity and vulnerability to tooth decay.
Heightened tooth sensitivity — Tooth sensitivity can be exacerbated by foods that are hot, cold, or sweet.
Erosion of Enamel – Enamel erosion is permanent and once the enamel is damaged, the teeth are forever damaged.
Bad breath – The acidic nature of lemon juice can change the pH balance of your mouth and create a suitable environment for harmful bacteria, which in turn disrupts healthy dental hygiene and causes bad breath.
What the American Dental Association (ADA) Has to Say
(That means lemon juice and other acidic home remedies for teeth whitening come from a long line of teeth destroyers; the American Dental Association recommends against it because of the very high likelihood for damage to enamel.) Their more cautious approach also includes professional whitening treatments, whitening kits, and maintaining regular tooth brushing with fluoride toothpaste.
Natural Options to Whiten Your Smile Other Than Lemon

If you’re seeking natural ways to achieve a whiter smile without those acidic kinds of food, consider these options:
- Activated Charcoal
One of the popular natural teeth whiteners is activated charcoal, which absorbs stains and toxins from the teeth surface. However, as a toiletry product, it is a safer option to lemon, can also not harm enamel (if used properly).
- Coconut Oil Pulling
The process of coconut oil pulling is as follows: One tablespoon of coconut oil is swished around in your mouth for 15-20 mins. Many people have begun to use coconut oil for oil pulling as well, as its lauric acid can help eliminate harmful bacteria and improve the health of the mouth.
- Banana Peels
Banana peels are sources of potassium, magnesium, and manganese, which could help whiten teeth when rubbed on the enamel.
- Baking Soda and Hydrogen Peroxide
Hydrogen peroxide is a mild bleaching agent and baking soda is a mild abrasive. This combination appears in commercial teeth-whitening products.
- Good Realignment of Braces and Dental Rediscovery
This strategy in conjunction with daily brushing with a fluoride whitening toothpaste will keep those pearly whites protected and shining bright!
