Natural teeth whitening remedies: do they work and are they safe?


A bright, white smile is often associated with beauty and good oral health. Over time, various factors such as aging, diet, lifestyle habits, and genetics can cause teeth to become stained or discolored, leading many individuals to seek ways to achieve a whiter smile. In addition to professional teeth whitening options, there is a growing interest in natural teeth whitening remedies. These remedies often use household ingredients or natural substances to lighten tooth color. In this blog, we will explore popular natural teeth whitening remedies, examine their effectiveness, and discuss their safety compared to professional teeth whitening treatments.

The Appeal of Natural Teeth Whitening Remedies

Natural teeth whitening remedies have gained popularity for several reasons:

a. Accessibility: 

Natural remedies often use household ingredients that are readily available, making them convenient for individuals who prefer at-home solutions.

b. Cost-Effectiveness: 

Natural remedies are generally more affordable compared to professional teeth whitening treatments, which can be appealing to those on a budget.

c. Minimal Chemical Exposure: 

Many natural remedies avoid the use of harsh chemicals commonly found in commercial teeth whitening products, which may be perceived as a safer option by some individuals.

d. Environmental Consciousness: 

Some individuals may choose natural remedies due to environmental concerns, as they typically involve fewer chemicals and packaging waste.

Popular Natural Teeth Whitening Remedies

There is a wide range of natural teeth whitening remedies that people use to brighten their smiles. Some of the most popular natural remedies include:

a. Baking Soda: 

Baking soda is a common household ingredient that is believed to have mild abrasive properties, helping to remove surface stains on teeth.

b. Hydrogen Peroxide: 

Hydrogen peroxide is a natural bleaching agent that is often found in commercial teeth whitening products. It is used in some natural remedies, but caution should be exercised due to its potential to cause tooth sensitivity and gum irritation in high concentrations.

c. Coconut Oil Pulling: 

Oil pulling involves swishing coconut oil in the mouth to remove bacteria and plaque. Some people claim that it can also help whiten teeth, although scientific evidence is limited.

d. Apple Cider Vinegar: Apple cider vinegar is acidic and may help remove surface stains on teeth. However, its acidic nature raises concerns about potential enamel erosion if used excessively.

e. Activated Charcoal: 

Activated charcoal is believed to adsorb surface stains and toxins from the teeth, although research on its effectiveness and safety is limited.

f. Strawberries and Citrus Fruits: 

Some individuals use strawberries or citrus fruits like lemon or orange peel to rub on their teeth, as they contain natural enzymes that may have mild whitening effects.

Effectiveness of Natural Teeth Whitening Remedies

The effectiveness of natural teeth whitening remedies varies depending on the remedy and individual factors such as the type and severity of tooth discoloration. While some people may report positive results with certain natural remedies, it is essential to understand that scientific evidence supporting their effectiveness is generally limited.

a. Baking Soda: 

Baking soda’s mild abrasive properties may help remove some surface stains on teeth, resulting in a slight whitening effect.

b. Hydrogen Peroxide: 

Hydrogen peroxide is a proven bleaching agent used in commercial teeth whitening products. In low concentrations, it may help lighten tooth color, but high concentrations may cause tooth sensitivity and gum irritation.

c. Coconut Oil Pulling: 

Limited scientific studies exist to support the claim that coconut oil pulling has a significant teeth whitening effect.

d. Apple Cider Vinegar: 

While apple cider vinegar may have some effect on surface stains, its acidic nature raises concerns about potential enamel erosion with prolonged use.

e. Activated Charcoal: 

The effectiveness of activated charcoal for teeth whitening is debatable, and its abrasive nature raises concerns about enamel wear.

f. Strawberries and Citrus Fruits: 

The natural enzymes in strawberries and citrus fruits may have some impact on tooth color, but they may also contribute to enamel erosion due to their acidic content.

It is essential to approach natural teeth whitening remedies with caution and not expect the same level of effectiveness as professional teeth whitening treatments. For more severe tooth discoloration or stubborn stains, professional treatments may provide more reliable and noticeable results.

Safety Considerations for Natural Teeth Whitening Remedies

While natural teeth whitening remedies may seem appealing, it is crucial to consider their safety before using them:

a. Enamel Erosion: 

Many natural remedies, such as apple cider vinegar and citrus fruits, are acidic and can potentially erode tooth enamel with prolonged use. Enamel erosion can lead to tooth sensitivity and increased susceptibility to dental problems.

b. Tooth Sensitivity: 

Some remedies, particularly those with abrasive properties or high concentrations of bleaching agents, may cause tooth sensitivity or gum irritation.

c. Lack of Regulation: 

Unlike professional teeth whitening treatments, natural remedies are not regulated by dental authorities. This lack of oversight means that the safety and effectiveness of these remedies may not be well-documented or scientifically proven.

d. Allergic Reactions: 

Individuals may have allergies or sensitivities to certain natural ingredients, leading to adverse reactions when used as teeth whitening remedies.

e. Interaction with Dental Restorations: 

Natural remedies may not work on dental restorations such as crowns, veneers, or fillings, potentially resulting in uneven tooth color.

Professional Teeth Whitening Treatments

Professional teeth whitening treatments are performed by dental professionals in a dental office or supervised at-home settings. They involve the use of higher concentrations of bleaching agents, such as hydrogen peroxide or carbamide peroxide, to achieve more immediate and significant whitening results.

In-Office Professional Teeth Whitening:

In-office professional teeth whitening offers immediate and noticeable results. Dental professionals use higher concentrations of bleaching agents and may incorporate special activation techniques to accelerate the whitening process.

Advantages of in-office professional teeth whitening:

Immediate Results: 

Patients can see significant improvements in tooth color after a single dental appointment.

Professional Supervision: Dental professionals ensure the safety and efficacy of the treatment.


The dentist can tailor the treatment to address specific dental concerns and desired outcomes.

b. At-Home Professional Teeth Whitening:

At-home professional teeth whitening involves custom-fitted trays or strips provided by the dentist and prescribed bleaching gel containing lower concentrations of the bleaching agent. Patients wear the trays or strips for a designated period each day, achieving gradual whitening results over time.

Advantages of at-home professional teeth whitening:


Patients can whiten their teeth at their convenience, following a schedule prescribed by the dentist.

Gradual Whitening: 

The lower concentration of bleaching agents reduces the risk of tooth sensitivity and allows for more gradual results.

Safety and Effectiveness of Professional Teeth Whitening

Professional teeth whitening treatments conducted by dental professionals are generally considered safe and effective when used as directed. The treatments are tailored to each individual’s dental health and goals, ensuring that the concentration of the bleaching agent and treatment duration are appropriate for their specific needs.Dental professionals also take into account any existing dental restorations or oral conditions that may affect the whitening process. The supervision provided during the treatment helps minimize potential risks and ensures optimal outcomes.


Natural teeth whitening remedies have gained popularity for their accessibility, cost-effectiveness, and minimal chemical exposure.

Moreover, many natural remedies carry potential safety risks, such as enamel erosion and tooth sensitivity.In comparison, professional teeth whitening treatments performed by dental professionals offer immediate and noticeable results.
