Safest Teeth Whiteners
The safest ways to whiten your teeth explained
Many teeth whitening products on the market use chemicals to bleach teeth. This is a concern for many people. Fortunately, it is possible to whiten your teeth without any of the harmful chemicals.
There are many ways to whiten your teeth naturally. You can purchase natural whitening products, try home remedies, or use a mixture of both for a brighter smile.
Popular ways to whiten teeth include:
Teeth whitening is a popular cosmetic dental treatment. In fact, Americans spend $1.4 billion annually on non-prescription teeth whitening products. $3.2 billion is spent on whitening treatments worldwide.
Teeth can turn yellow due to intrinsic or extrinsic discoloration:
Extrinsic discoloration affects the outside of your teeth. It is caused by consuming certain foods and beverages (e.g., tea, red wine, coffee, and foods with dyes).
Tobacco smoke can also cause this type of tooth discoloration. Poor oral hygiene can leave teeth looking darker and yellow due to plaque build-up. Since it only affects the outside of your teeth, whitening products can treat extrinsic discoloration.
Intrinsic discoloration forms within your teeth.
This type of discoloration is commonly caused by a childhood illness, genetics, infection, trauma, aging, or medications. To remove intrinsic discoloration, professional whitening treatment is typically necessary.
There are a few ways to naturally whiten your teeth at home, including:
The best ways to keep your teeth white include:
Many healthy foods can also improve teeth health, strength, and brightness. These include, but are not limited to:
Calcium is essential for strong bones, including your teeth. The stronger your teeth are, the lower the risk of damage. And the less damaged your teeth are, the less prone they are to yellowing.
Cheese, yogurt, and milk contain lactic acid and the enamel-fortifying mineral calcium, which strengthen your teeth and decrease the risk of stains/damage.
Many vegetables and dairy-free products also contain calcium. These include leafy green vegetables, soy products, legumes, beans, and nuts, among others.
Fruits like papayas and pineapples contain the enzymes papain and bromelain, which have been shown to have whitening effects on teeth. However, more research is still being done on the effectiveness of these enzymes.
Hydrogen peroxide (HP) is a natural bleaching agent. It also kills bacteria in your mouth, which can help prevent cavities and oral disease.
Many commercial whitening products list hydrogen peroxide as an ingredient. However, they often contain high concentrations of the chemical compound.
When hydrogen peroxide is heavily concentrated, it can lead to gum irritation, tooth sensitivity, and/or enamel erosion. However, studies show HP is safe to use if it is diluted in toothpaste or mouthwash.
It is best to use whitening products that contain 1 to 1.5 percent hydrogen peroxide. Many of these products also have small amounts of baking soda.
Do not overuse whitening products containing hydrogen peroxide or baking soda. Always make sure you read the instructions before using them.
Peroxide-containing products are safe to use on your teeth in small doses. However, some people prefer to use completely natural products.
Many natural whitening strips, toothpastes, and mouthwashes on the market use essential oils and botanicals to whiten teeth gradually.
Before purchasing a natural teeth whitening product, it is essential to look for certain features to ensure you are buying the best product.

If you do not want to use peroxide-containing products, there are many other natural whitening treatments available.
Our team has put together a list of the best natural products based on the standards listed above:

We recommend purchasing Primal Life’s White Whitening Gel (listed below) instead of the Activated Charcoal Whitening Gel.

Lumineux’s Whitening Kit is a certified non-toxic, microbiome safe, and clinically proven teeth whitening regimen.
Lumineux products combine ancient homeopathic ingredients with scientific evidence.
The formulas include ingredients like coconut oil, sage oil, and lemon peel oil. These naturally-derived ingredients help remove surface stains and freshen your breath naturally.

The Cali White Botanical Whitening System is non-toxic and contains zero peroxide.

Cali White’s whitening gel tastes better than traditional gels because it contains Xylitol (non-toxic sugar alcohol) and organic peppermint oil. This oil is also a natural antiseptic.
Some natural teeth whitening methods are capable of lightening your teeth safely. However, other popular whitening methods are not proven to work. They may actually do more harm than good.
According to the American Dental Association (ADA), you should avoid whitening your teeth with:
The answer is mixed. While studies have shown that activated charcoal removes stains, it is not the most effective option.
A 2017 review of charcoal-based toothpastes (by JADA) found that 96 percent of them claimed to have whitening effects. Forty-six percent of them were able to detoxify teeth.
This shows that charcoal does have whitening properties. However, the problem is that there is no clear definition of what it means to detoxify something (at least not in the mouth).
In addition to this, the toxicity of charcoal-based dental products hasn’t been thoroughly tested.
No evidence shows that activated charcoal is 100 percent safe. Some dentists are also concerned that charcoal's abrasive particles whiten teeth by removing a layer of enamel.
Until more research comes out, it is best to avoid whitening products containing charcoal.
