How To Whiten Your Teeth Naturally

Common teeth whitening products on the market use chemicals to bleach teeth, which can be a concern for many people. Fortunately, it is possible to whiten your teeth without any harmful chemicals.

You can try alternative teeth whitening options by purchasing natural whitening products, trying home remedies, or using a mixture of both for a brighter smile.

6 Ways to Whiten Your Teeth Naturally (Home Remedies)

If you want to whiten your teeth naturally at home, there are a few things you can try, including:

1. Practice Good Oral Hygiene

The best way to keep your teeth white is to have a good oral hygiene routine. This involves brushing your teeth twice a day for two minutes at a time and flossing.

Other practices you can do include:

  • Avoid smoking or using tobacco products
  • Visit your dentist every six months for professional teeth cleanings
  • Limit intake of staining products like coffee, tea, red wine, dark berries, and curry powder
  • Limit or avoid sugary foods and drinks

2. Maintain a Healthy, Balanced Diet

Many healthy foods can improve teeth health, strength, and brightness. These include, but are not limited to: 

  • Coarse vegetables like broccoli High in fiber and require more chewing to break down, which increases saliva production and helps scrape away stains
  • Pineapple — Contains bromelain, an anti-inflammatory compound that helps remove stains
  • Dairy products Increase saliva production to help remove stains
  • Nuts and seeds — Natural exfoliators that help remove stains
  • Onions — Contain sulfur to help keep plaque from forming on teeth
  • Celery and carrots High in water, which helps remove debris between teeth

3. Get Enough Calcium in Your Diet

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 the teeth and decrease the risk of stains and damage.

Many vegetables and dairy-free products also contain calcium. These include:

  • Leafy green vegetables
  • Soy products
  • Legumes
  • Beans
  • Nuts

4. Eat Fruits Containing Papain and Bromelain

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.

5. Baking Soda and Hydrogen Peroxide (Diluted)

Hydrogen peroxide (HP) is a natural bleaching agent that can kill bacteria in your mouth. It can help prevent cavities and oral diseases.

Many commercial whitening products list hydrogen peroxide as an ingredient. However, they often contain high concentrations of it, which can lead to:

  • Gum irritation
  • Tooth sensitivity
  • Enamel erosion

However, studies show HP is safe to use if it is diluted in toothpaste or mouthwash. Products that contain 1 to 1.5 percent hydrogen peroxide are best. 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. 

6. Use Natural Whitening Products

Peroxide-containing products are safe to use on 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.

Why Do Teeth Stain?

Teeth can turn yellow due to intrinsic or extrinsic discoloration.

Extrinsic Discoloration

External staining or extrinsic discoloration affects the outside of your teeth. It is caused by consuming certain foods and beverages, including:

  • Tea
  • Red wine
  • Coffee
  • Foods with dyes
  • Tobacco

Poor oral hygiene can leave teeth looking darker and yellow due to plaque build-up. Since at-home whitening products only affect the outside of your teeth, they can treat extrinsic discoloration.

Intrinsic Discoloration

Internal staining or intrinsic discoloration forms inside your teeth. It is commonly caused by several factors, including:

  • Childhood illnesses
  • Genetics
  • Infection
  • Trauma to the teeth
  • Aging
  • Medications

To remove intrinsic discoloration, professional whitening treatment is typically necessary.

Is Activated Charcoal Safe on Teeth?

The answer is mixed. While studies have shown that activated charcoal removes stains, it is not the most effective option. 

A systematic review of 208 articles revealed that charcoal-based teeth whitening products have a lower whitening effect.11 It also says that these products carry more risk of dental erosion than other whitening alternatives due to their highly abrasive properties. 

Charcoal does have whitening properties. However, the toxicity of charcoal-based dental products hasn’t been thoroughly tested. Until more research comes out, avoiding whitening products containing charcoal is best. 

5 Unproven Natural Teeth Whitening Methods

Some 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:

1. Acidic Fruits 

Naturally acidic substances can wear away tooth enamel and cause cavities, sensitivity, and other conditions. Avoid using lemons, oranges, limes, strawberries, or other acidic fruits to whiten your teeth.

However, eating them as part of a healthy diet is perfectly safe. Make sure to eat them in moderation, as an increased intake of acidic foods can cause tooth sensitivity and wear away enamel.

2. Apple Cider Vinegar

Vinegar contains acid, which can wear away tooth enamel. Do not put vinegar directly onto your teeth, as it can cause tooth erosion and, eventually, decay.

3. Baking Soda-Hydrogen Peroxide Paste 

Applying a homemade baking soda-hydrogen peroxide paste directly to your teeth is abrasive because the concentration of the mixture is often too strong. Overuse can erode your enamel.

4. Turmeric and Other Spices

There is no reliable evidence that shows putting turmeric on teeth whitens them. Many herbs are beneficial for your health but will not whiten teeth. 

5. Oil Pulling

Oil pulling is an Ayurvedic practice of swishing oil through the teeth and around the mouth. Coconut oil and olive oil are commonly used. This practice may improve bad breath, but it will not remove stains from teeth.
