Safest Ways to Whiten Teeth


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 Prevent Tooth Discoloration

To protect your pearly whites from becoming discolored, you should:

  • Brush and floss your teeth twice daily
  • Avoid smoking or using tobacco products
  • Consume tooth-staining foods in moderation
  • Brush and floss after eating dark-colored foods
  • Drink tea or coffee with milk 
  • Drink iced tea, iced coffee, juices, or other colored beverages through a straw
  • Rinse with water after drinking coffee or tea
  • Chew sugarless gum to neutralize the acids in your mouth 
  • Eat high-fiber foods to lower the acid level in your mouth
  • Eat leafy greens, which generate more saliva in the mouth and can “scrub” the teeth clean
  • Attend regular dental cleanings twice annually
  • Try oil pulling with coconut oil to remove toxins
  • Brush your tongue to remove bacteria

For a whiter smile, you should limit your intake of foods that stain the surfaces of your teeth, including:

  • Red wine
  • Blueberries
  • Blackberries
  • Pomegranates
  • Soda
  • Barbecue sauce
  • Coffee
  • Green tea
  • Black tea
  • Sugary treats
  • Marinara
  • Curry
  • Paprika
  • Balsamic vinegar

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
  • Apply lemon and apple cider vinegar which brighten teeth
  • 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 the 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.

While limited data is available on the effects of LED light in dentistry, studies have shown that the light sources have little effect on teeth sensitivity.
