Teeth Whitening: Myths vs. Facts

teeth whitening myths

In addition to improving one’s appearance, whiter teeth are often considered a symbol of health, beauty, and confidence. This has led many people to seek teeth whitening for a brighter and more attractive smile. One of the most popular cosmetic dental treatments for smile enhancement is tooth whitening. Despite its popularity, several myths have caused confusion about teeth whitening, which makes some people hesitant to pursue the many benefits of having whiter teeth.


New call-to-action


This article exposes these myths and presents the facts that can help you decide if teeth whitening is right for you.

Teeth Whitening Basics

Before considering the myths and facts, it's helpful to understand the basics of this popular cosmetic dental treatment before deciding on a treatment plan. Discovering why you have stained teeth is crucial to making the right decision about your teeth whitening.

Teeth come in a natural range of shades, from ivory to slightly yellow. This variation depends on genetics and the thickness of your enamel, which is the white outer layer of your teeth. Over time, dental enamel can become stained from two main sources:

Extrinsic tooth stains

These are surface stains caused by colored foods and drinks, such as coffee, sports drinks, berries, and tomato sauce. Other causes of surface stains include smoking and other tobacco products.

Intrinsic tooth stains

These deeper stains come from within the tooth itself due to aging, injuries, medications such as tetracycline, or excessive fluoride exposure during childhood.

Teeth whitening treatments target mostly extrinsic stains, while intrinsic ones may require different cosmetic treatments such as porcelain veneers or dental crowns.

Depending on the type and severity of the discoloration, teeth whitening can lighten the shade of your teeth. There are two categories of whitening procedures that can accomplish this for you:

The process of teeth whitening involves using bleaching agents, most commonly hydrogen peroxide or carbamide peroxide. These compounds break down into oxygen molecules that penetrate the porous outer layer of your enamel. The oxygen then reacts with the discolored molecules to break the bonds that hold them together. This treatment results in lighter-colored enamel without affecting the structure of your teeth.

Understanding these basics can help you make the best decisions when it comes to whitening your teeth. You will be better equipped to set realistic goals and choose the most suitable whitening method based on your needs and lifestyle. With this knowledge, you will also be able to dispel the myths surrounding this beneficial cosmetic procedure. Three of the most common myths are discussed below.

Myth #1: All teeth whitening treatments are the same.

The most common myth that dentists hear from patients is their belief that at-home, over-the-counter (OTC) products provide the same results as professional, in-office treatments. This myth can actually lead you to choose a whitening option that isn’t best suited for your needs. In reality, the effectiveness, safety, and suitability of teeth whitening methods vary significantly, influenced by factors such as the formulation of the whitening agent, the concentration of active ingredients, application method, and individual dental health.

Fact: There are significant differences between professional whitening and over-the-counter (OTC) treatments.

Although the goal of whitening your teeth is the same, there are important differences between the two, including:

  • Strength: Your dentist uses a higher concentration of bleaching solution. This typically results in whiter teeth in less time. OTC at-home bleaching strips, gels, and trays use weaker solutions due to safety concerns.
  • Application: Your dentist is an expert in creating bright and beautiful smiles. Using professional equipment, custom-made delivery systems, and predictable bleaching materials, your treatment is ensured to be safe and effective with precise delivery of the bleaching solution. This is a stark contrast to items you purchase in a grocery or drug store. These whitening products use a one-size-fits-all approach that can be less effective and safe.
  • Supervision: Professional whitening allows your dentist to monitor your whitening to monitor any risks and address any sensitivity issues quickly before they worsen.

Additionally, laser teeth whitening, as used by Palmetto Dental Arts, allows for added precision in whitening individual teeth. Laser teeth whitening technique uses the latest technology and dental materials for fast and superior teeth whitening results.

Myth 2: Teeth whitening damages enamel.

A common concern you may have about teeth whitening is that the process can damage or weaken your tooth enamel. This is usually a misunderstanding about the strength of the bleaching agents used in whitening treatments and their potential to harm the surface of the enamel. This often leads to further concern about tooth sensitivity, possible dental cavities, and other dental problems.

Fact: Teeth whitening has been found to be safe and poses no significant risk to tooth enamel when performed under the supervision of a dentist.

The bleaching agents used in most whitening products, such as hydrogen peroxide or carbamide peroxide, have been extensively studied and are considered safe for teeth. For ensured safety, professional-strength solutions must be applied under the direction of your dentist. This is especially true if you have damaged enamel.

Myth #3: Teeth whitening is permanent.

A common misconception about teeth whitening is that once your teeth are whiter and brighter, no further effort will be required to maintain and care for your new smile.

Fact: The reality is that teeth whitening is not a permanent solution for tooth discoloration.

How long you retain the brightness of your whitened teeth before needing them refreshed can depend on several variables, such as:

  • Diet: Some foods and drinks are prone to cause restaining more quickly. These include coffee, tea, tomato products, berries, energy drinks, and soy sauce.
  • Tobacco: Smoking or using other tobacco products can lead to needing whitening treatments sooner.
  • Oral hygiene: Regular oral hygiene with brushing and flossing is one of the best ways to help prolong the effects of your teeth whitening.
  • Age: Enamel thins with age, making your teeth more susceptible to acquiring surface stains.

To prolong the effects of your teeth whitening and maintain your bright smile, consider the following tips:

  • Avoid or limit the consumption of stain-causing foods and beverages.
  • Brush your teeth or rinse your mouth with water after consuming foods or drinks that are prone to stain your teeth.
  • Maintain a consistent oral hygiene routine, including regular brushing, flossing, and dental check-ups.
  • Avoid all tobacco products.
  • Use whitening toothpaste and other whitening products as recommended by your dental professional.

It's important to have realistic expectations when it comes to the longevity of teeth whitening results. While the treatment can provide a noticeable improvement in the whiteness of your smile, it's not a one-time, permanent solution. By understanding the temporary nature of whitening and taking steps to maintain your results, you can enjoy a brighter smile for longer.
