Is Teeth Whitening Safe?
Teeth whitening is the process of removing stains from your teeth and brightening your smile.
Teeth whitening treatments include in-office bleaching procedures, dentist-grade products for at-home use, and over-the-counter (OTC) whiteners.
Tooth whitening is safe and effective when the manufacturer’s protocol is followed or performed by a dental professional.
Though whitening is safe, there are still some risks that users should know. Temporary tooth sensitivity and gingival inflammation are the most common adverse effects of teeth whitening.
Why Do Teeth Stain?
Many factors can cause teeth stains, including:
- Infections or tooth decay
- Genetics
- Too much fluoride
- High-acidity foods and drinks
- Tobacco
- Trauma
- Poor oral hygiene
- Aging
- Certain antibiotics (tetracycline, chlorhexidine, etc.)
How to Safely Whiten Your Teeth
There are a few ways to whiten your teeth safely and effectively from the comfort of home:
- Use over-the-counter teeth bleaching products that contain baking soda or hydrogen peroxide
- Look for products with an American Dental Association (ADA) Seal of Acceptance
- Avoid high-colored food and drinks
- Use a tooth whitening pen
- Use teeth-whitening toothpaste and mouthwashes as maintenance
- Brush and floss daily
- Invest in an electric toothbrush
- Use a whitening pre-rinse before brushing
You should also eat more foods that brighten your teeth, including:
- Apples improve gum health and stimulate saliva production, which helps rinse away stains.
- Cheese, milk, and yogurt strengthen tooth enamel and appearance.
- Nuts, celery, broccoli, and carrots have an abrasive texture that scrubs off stains.
- Raw onions contain sulfur, which stops plaque from forming.
- Strawberries contain malic acid, which removes surface stains lurking on teeth.
Teeth whitening is only safe for patients with good dental hygiene. If you have cavities, gum disease, or other oral health conditions, refrain from using whitening products.
Before using DIY teeth whitening methods, you should first talk to your dentist about what teeth whitening options are best for you.
Is Activated Charcoal Teeth Whitening Safe?
Activated charcoal is not proven to be safe or effective for teeth whitening. The American Dental Association has not given activated charcoal its Seal of Acceptance, which certifies a treatment is safe to use and is recommended by dentists.
Not only has charcoal not been proven safe, but it might also damage your teeth.
Charcoal is abrasive and can erode enamel, which is irreversible. If the charcoal erodes too much of your enamel, it makes your teeth look more yellow. This is because thinning enamel reveals more of the inner dentin, which is darker.
Enamel loss can lead to increased sensitivity and susceptibility to dental decay.
Can You Use Turmeric for Teeth Whitening?
Turmeric is not recommended for teeth whitening because it has not been certified as a safe or effective method. The American Dental Association has not given turmeric its Seal of Acceptance, which authorizes a treatment as safe for use.
There is limited data on turmeric’s efficacy as a natural whitening product. However, turmeric is an astringent, which may impact tooth enamel and health. And in one study, turmeric created no difference in teeth color.
What is the Most Effective Way to Whiten Teeth?
The safest and most effective way to whiten your teeth is with professional teeth whitening treatments. These methods provide instant results and are completed in a dentist's office. However, professional whitening is expensive, making it less desirable for many people.
Instead, NewMouth recommends at-home whitening products that contain safe levels of peroxide. Products containing either hydrogen or carbamide peroxide are safe and effective teeth whitening agents.
At-home teeth bleaching products typically contain 5 to 10 percent hydrogen peroxide or 35 percent carbamide peroxide. They are applied for 10 to 30 minutes for multiple days in a row.
Using at-home whitening products that contain higher levels of peroxide can lead to increased sensitivity and gum irritation.
10 Best Teeth Whitening Products (for Enamel-Safe Whitening)
Here are the best (and safest) at-home whitening products recommended by NewMouth:
Snow Teeth Whitening
Best Overall & Best for Sensitive Teeth

hismile's teeth whitening kit uses three powerful, enamel-safe ingredients to provide instant results without any sensitivity:
- Hydroxyapatite (nHAp) rebuilds the protective layer of teeth and replaces lost minerals.
- Phthalimidoperoxycaproicacid (PAP) is clinically proven to whiten teeth without sensitivity or gum irritation.
- Potassium citrate helps relieve pre-existing sensitivity and provides long-term protection.
hismile is also peroxide-free. Peroxide as a bleaching agent can cause sensitivity, gum irritation, and the demineralization of teeth.

The product contains 2 percent hydrogen peroxide, which dentists recommend for whitening. It also contains fluoride to protect against cavities.
Whitening toothpaste is not as effective at whitening your teeth as LED kits or Whitestrips. But it can help remove and prevent surface stains. Therefore it should be used in addition to one of these other methods.
Cost: $
Colgate Optic White Whitening Mouthwash contains 2 percent Hydrogen Peroxide. This can slightly help remove surface stains.
However, whitening results from mouth rinse alone will not be as effective as an LED whitening kit or Whitestrips.
Because it does help prevent new stains, whitening mouthwash is best used in addition to another whitening product.
Cost: $
This LED whitening kit was designed to reduce sensitivity and uses enamel-safe ingredients.
If you prefer to use the same brand for every step of your oral health routine, you can use Colgate whitening toothpaste, mouthwash, and LED kit.
This kit can be used hands-free, only takes 10 minutes, and doesn’t require a smartphone.
Cost: $$$
Side Effects Of LED Teeth Whitening
Risks commonly reported with teeth whitening include tooth sensitivity and gingival irritation. The severity of these side effects is directly connected to the concentration of peroxide bleach used and the duration of treatment.
While limited data is available on the effects of LED light in dentistry, studies have shown that light sources have little effect on teeth sensitivity.
Tips for Preventing Tooth Discoloration
To protect your pearly whites from becoming discolored, you should:
- Brush and floss your teeth twice daily
