Can Anyone Whiten Their Teeth?

Can Anyone Whiten Their Teeth

Teeth whitening has gained immense popularity in recent years, offering individuals a brighter smile and increased confidence. Navigating the world of dental aesthetics, The House of Mouth™, renowned for its passion for dentistry and commitment to enhancing smiles, brings you a comprehensive guide on teeth whitening.  

With extensive expertise, we aim to demystify the process, highlighting who can benefit and who should reconsider this popular procedure. This article delves into the ideal and non-ideal candidates for teeth whitening, ensuring oral health remains a priority. 

Teeth whitening is a simple process that involves the use of bleaching agents, primarily hydrogen peroxide or carbamide peroxide, to break stains into smaller pieces. This process doesn’t structurally change the colour of the teeth but makes the teeth appear whiter by dispersing the concentration of the discolouration.   

Understanding the types of stains

Teeth can become discoloured for various reasons.  

  • Extrinsic stains, which are on the tooth’s surface, are often caused by dark-coloured beverages like coffee, tea, and red wine, as well as tobacco use.  
  • Intrinsic stains, on the other hand, are located within the tooth and can be a result of factors like aging, trauma, or exposure to certain medications during tooth development.  

Understanding the type of stain is crucial as it determines the effectiveness of the whitening procedure. 

Oral health comes first.

It’s a common misconception that teeth whitening is purely cosmetic. In reality, the health of one’s teeth and gums play a pivotal role in the success of the procedure. Healthy teeth, free from cavities and gum disease, respond better to whitening treatments and experience fewer side effects.  

Moreover, whitening treatments on compromised teeth can lead to exacerbated dental issues. Thus, ensuring optimal oral health is not just a recommendation; it’s a prerequisite. Learn more about myths about Teeth whitening in this article.  

Suitable Candidates for Teeth Whitening

While many individuals can safely undergo teeth whitening and have a lot of benefits, it’s essential to note that certain restorations, such as fillings, implants, crowns, and dental bridges, won’t whiten with the procedure.

Let’s delve into who makes an ideal candidate for this procedure. 

Natural Teeth

Natural Teeth: Individuals with natural, healthy teeth, free from restorations, often see the most uniform and pleasing results from teeth whitening. The natural enamel responds well to the bleaching agents, resulting in a brighter smile. 

External Stains

External Stains: Those with stains caused by external factors, such as coffee, tea, red wine, and tobacco, are prime candidates. These stains, known as extrinsic stains, reside on the outer layer of the teeth and are often effectively lifted with professional teeth whitening treatments.

Good Oral Health

Good Oral Health: An essential prerequisite for teeth whitening is good oral health. Those without active cavities, gum disease, or severe tooth sensitivity are more likely to experience a comfortable and successful whitening procedure. It’s crucial to address any underlying dental issues before considering cosmetic treatments.  

Understanding Of The Process

Understanding of the Process: Ideal candidates are those who have realistic expectations and an understanding of the procedure. Teeth whitening can significantly enhance one’s smile, but it’s essential to remember that results can vary based on individual factors. 


Restorations: It’s worth noting that while individuals with dental restorations (fillings, crowns, bridges, and implants) can undergo teeth whitening, the restorative materials do not respond to bleaching agents in the same way natural teeth do. This means that while the natural teeth may lighten, the restorations will remain their original colour, potentially leading to a mismatch in shades. It’s essential to consult with a dentist to discuss potential outcomes and solutions. 

Unsuitable Candidates For Teeth Whitening

Unsuitable Candidates for Teeth Whitening

Teeth whitening, while transformative for many, isn’t a one-size-fits-all solution. Certain individuals may not be ideal candidates for the procedure due to various reasons, ranging from health conditions to the nature of their dental issues. Here’s a closer look at those who might want to reconsider or delay teeth whitening: 

Pregnant Or Lactating Women

Pregnant or Lactating Women: The safety of teeth whitening during pregnancy or lactation hasn’t been extensively studied. As a precaution, many dental professionals advise against undergoing the procedure during these periods to avoid any potential risks to the mother or the baby.

Children Under 16

Children Under 16: The pulp chamber, or the innermost part of the tooth, is enlarged until this age. Whitening procedures can irritate the pulp, leading to increased sensitivity or even potential damage in younger individuals.

Dental Conditions

Dental Conditions: Those with active dental conditions such as periodontal disease, tooth decay, cavities, and exposed roots should prioritize treating these issues. Whitening an unhealthy mouth can exacerbate existing problems and lead to severe pain and sensitivity.


Allergies: Some individuals may be allergic or sensitive to ingredients used in the whitening process, especially bleaching agents like peroxide. It’s essential to undergo an allergy test or discuss any known allergies with a dentist before the procedure.

Sensitive Teeth 23

Sensitive Teeth: For those already battling with tooth sensitivity, teeth whitening can intensify the discomfort. However, there are gentler options available, such as lower-concentrated peroxide treatments or even peroxide-free alternatives.

Unrealistic Expectations

Unrealistic Expectations: Teeth whitening can offer significant improvements, but it’s not a miracle cure. Those seeking extreme results, like a blindingly white shade, might be disappointed. It’s essential to have a candid discussion with a dentist about achievable outcomes.

Options for Teeth Whitening

Options For Teeth Whitening

There are various teeth whitening options or teeth whitening products offered by House of Mouth, ranging from professional treatments to at-home kits

  • In-Office Whitening: This professional treatment, often referred to as chairside whitening, is performed by dental professionals. It offers the most dramatic results in the shortest amount of time, often in just one session. The dentist uses a high concentration of bleaching agent, ensuring both safety and effectiveness. 
  • At-Home Whitening Kits: These kits, allow individuals to whiten their teeth in the comfort of their homes. They usually include custom-fitted trays and a lower concentration of bleaching agent than in-office treatments. 
  • Over-the-Counter Products: Ranging from whitening toothpaste and whitening pens to strips and gels, House of Mouth offers some best-at-home teeth whitening products and kits that offer a more affordable and convenient way to achieve a brighter smile. However, the results might be less dramatic compared to professional treatments. 
  • Natural Whitening: Some individuals opt for natural methods, like activated charcoal or baking soda. While these can offer some improvement in tooth shade, it’s essential to be cautious as abrasive substances can wear down enamel over time.

Safety is a paramount concern when it comes to any cosmetic procedure. When conducted under the supervision of a dental professional, teeth whitening is considered safe. The procedure utilizes bleaching agents that have been rigorously tested and approved for dental use. However, it’s crucial to adhere to the guidelines and instructions provided by the dentist or the product manufacturer to avoid any adverse effects.

While teeth whitening can be a transformative experience for many, it is not a universal solution. Individuals with certain dental conditions, allergies, or those who are pregnant, lactating, or under the age of 16, should exercise caution. A thorough consultation with a dental professional can help determine suitability and tailor the treatment to individual needs.

A common misconception is that teeth whitening can damage the tooth enamel. However, when used correctly, the bleaching agents in whitening products are not harmful to the teeth. It’s essential to follow the recommended concentration and application time to prevent any potential damage. For a more in-depth understanding of this concern, refer to this article.

While teeth whitening is generally well-tolerated, some individuals may experience temporary side effects such as tooth sensitivity or gum irritation. These symptoms are usually mild and subside shortly after completing the treatment. For those with pre-existing sensitivity, using a lower concentration of bleaching agent or a desensitizing toothpaste can help alleviate discomfort.
