Top Ways to Whiten Teeth In 2024 - Part 1

A survey found that 80% of American adults aged 18-49 desire whiter teeth, and in 2016, over $1.4 billion was spent on at-home whitening products (1). With numerous options available, many teeth-whitening products use chemicals that may concern some individuals.

If you prefer to avoid chemicals, this article explores several natural and safe alternatives for teeth whitening.

**Oil Pulling**

Oil pulling is an ancient practice from India aimed at enhancing oral hygiene and removing toxins. This method involves swishing oil, such as coconut oil, around in your mouth to reduce bacteria and plaque, which can lead to yellowing teeth .

Coconut oil is favored for its pleasant taste and health benefits, including its high lauric acid content, which helps decrease inflammation and kill bacteria.

Although scientific studies have not definitively proven that oil pulling whitens teeth, many users report improved whiteness and brightness.

To perform oil pulling, swish 1 tablespoon (15 ml) of coconut oil in your mouth for 15–20 minutes. Spit it into the trash or toilet to avoid clogging your pipes.

**Baking Soda**

Baking soda, a common ingredient in commercial toothpastes, has mild abrasive properties that can help remove surface stains and create an alkaline environment to prevent bacterial growth .

While plain baking soda has not been proven to whiten teeth significantly, studies show that toothpastes with baking soda are effective in reducing plaque and improving dental health .

To use, mix 1 teaspoon (6 grams) of baking soda with 2 teaspoons (5 ml) of water and brush a few times a week.

Science has not yet proven that brushing with plain baking soda will whiten your teeth, but several studies show that toothpaste containing baking soda can improve dental health and may have a whitening effect.

**Hydrogen Peroxide**

Hydrogen peroxide is a natural bleaching agent also known for its antibacterial properties . While higher concentrations are used in commercial whitening products, a diluted 1.5% to 3% solution can be used at home.

Studies show that hydrogen peroxide in toothpaste can effectively whiten teeth. Use it as a mouthwash or mix with baking soda for a homemade toothpaste, but limit use to avoid potential enamel erosion.

**Fruits and Vegetables**

Eating raw, crunchy fruits and vegetables can help reduce plaque. Strawberries and pineapples are often suggested for their potential whitening effects.

However, while strawberries and baking soda may help exfoliate teeth, they are not proven to significantly whiten them . Pineapple's enzyme bromelain may aid in stain removal, but eating pineapple alone is unlikely to have a substantial effect.

**Regular Oral Hygiene**

Maintaining good oral hygiene through regular brushing and flossing is crucial for keeping teeth white. Brushing removes surface stains, and flossing helps prevent plaque buildup. Regular dental cleanings also contribute to a whiter smile.

**Preventing Stains**

To avoid staining, limit the intake of coffee, red wine, and other dark-colored foods and beverages. If consuming these, use a straw and brush your teeth about an hour afterward. Also, reduce sugar intake to prevent plaque buildup and ensure sufficient calcium intake to strengthen enamel.

**Unproven Methods**

Several natural whitening methods lack scientific validation. These include activated charcoal, kaolin clay, fruit peels, and apple cider vinegar. These methods have not been thoroughly tested for safety or efficacy.

Certainly! Here are three additional natural methods to whiten your teeth:

**Turmeric**

Turmeric, known for its vibrant yellow color and anti-inflammatory properties, has been used in traditional medicine for various health benefits. Some believe that turmeric can help whiten teeth due to its natural abrasiveness and its potential to reduce bacterial growth in the mouth . However, scientific evidence supporting turmeric’s effectiveness in teeth whitening is limited. To use, make a paste by mixing turmeric powder with coconut oil and brush your teeth with it. Be cautious as turmeric may temporarily stain your toothbrush or sink.

**Apple Cider Vinegar**

Apple cider vinegar (ACV) is often touted as a natural teeth-whitening remedy due to its acetic acid content, which can help break down stains on the teeth. However, the acidic nature of ACV means it should be used with caution. Excessive use can erode tooth enamel, leading to sensitivity and increased risk of cavities. To use ACV safely, dilute it with water (1 part ACV to 2 parts water) and swish it around your mouth for about 30 seconds before brushing. Limit this practice to a few times a week to prevent enamel damage .

**Activated Charcoal**

Activated charcoal is popular for its purported ability to absorb toxins and stains. The idea is that it binds to particles on the teeth, helping to remove surface stains. While some users report a whitening effect, scientific evidence supporting its effectiveness is limited, and there are concerns about its abrasive nature potentially damaging tooth enamel .

If you choose to use activated charcoal, use it sparingly. Dip a wet toothbrush into activated charcoal powder and gently brush your teeth for 1-2 minutes, then rinse thoroughly. Avoid frequent use to prevent enamel erosion.

**Conclusion**

Natural methods can help with teeth whitening by removing surface stains, but they may not be as effective as professional treatments. For more significant discoloration, consider consulting a dentist about stronger whitening options.
