Teeth Whitening in Singapore: Show Your Smile to The World

What Is Teeth Whitening?

Teeth whitening is a cosmetic dental procedure designed to lighten the colour of your teeth. A radiant, white smile not only communicates various emotions but also boosts your self-esteem. Dive deeper into this guide to discover various strategies for attaining a brighter smile.

What Causes Tooth Discolouration?

Tooth discolouration causes can be classified into intrinsic and extrinsic stains.

Extrinsic (External) Stains

Extrinsic stains impact the enamel, the outermost tooth layer. To minimise these stains, regular cleaning and moderation in consuming staining substances are essential. When stains occur, whitening treatments can be effective.

Possible Causes:

  • Food & Drinks: Beverages like tea, coffee, and wine have pigments that bind to tooth enamel.
  • Smoking: Tar in cigarettes causes a brownish discolouration.
  • Poor Oral Hygiene: Inadequate brushing or flossing allows plaque buildup, contributing to discolouration.
  • Ageing: Over time, enamel thins and more of the yellowish dentin shows through.

Intrinsic (Internal) Stains

Intrinsic stains reside deep within your teeth, beyond the enamel, and involve the dentine or cementum. These stains are usually typified by grey, brown, or yellow hues. Unlike surface stains, intrinsic discolourations require professional dental treatment as regular cleaning is ineffective.

Possible Causes:

  • Ageing
  • Medication
  • Dental trauma
  • Genetic disorders
  • Tetracycline (a type of antibiotic)
  • Overexposure to fluoride
  • Tooth decay (dental caries)
  • Root canal treatment
  • Heavy smoking

What Does Teeth Whitening Involve?

There are two main ways as to how teeth whitening can be done:

Teeth whitening is an effective way to brighten your smile. This cosmetic procedure utilises a bleaching gel that typically contains hydrogen peroxide.  Another common bleaching agent used in teeth whitening treatments is carbamide peroxide, which breaks down into hydrogen peroxide and urea in the mouth, offering a sustained whitening effect. When applied to your teeth, bleaching agents penetrate the enamel and break down the molecules causing discolouration.

  • Application: A whitening gel is carefully spread on the surface of your teeth.
  • Mechanism: The bleaching process involves chemical reactions which dismantle staining compounds within the tooth structure.
  • Effectiveness: Results can vary, depending on the type and severity of stains you have.
  • Duration: The time it takes to see results may differ according to the specific teeth whitening treatment you choose.

The choice between hydrogen peroxide and carbamide peroxide depends on your whitening goals, sensitivity, and whether the treatment is performed at home or in a dental office. Professional consultation can help determine which agent is best suited to your needs, ensuring both the effectiveness and safety of your teeth whitening process.

Teeth Whitening Treatment Options in Singapore

Singapore offers a variety of teeth whitening treatments catering to both extrinsic and intrinsic stains, as outlined earlier. From in-office procedures designed for rapid and pronounced whitening effects to take-home kits for gradual improvement, each method addresses the unique challenges presented by different types of tooth discoloration.

1. Chairside Teeth Whitening

Also known as “In-Office teeth whitening”, professional in-office whitening treatments are available for immediate results.


1. Light-Accelerated Whitening: Utilises a combination of a whitening gel and a special light (often LED or halogen) to speed up the bleaching process, offering significant whitening in about one hour.


2. Laser Teeth Whitening: Involves the application of a bleaching agent to the teeth, which is then activated and accelerated by laser light. This method is known for its efficiency and quick results.


3. Chemically Activated Whitening: This type of whitening does not require light or laser to activate the bleaching agent. Instead, it relies on a specially formulated gel that begins working upon contact with the teeth, suitable for those looking for a non-light-based option.


4. Hybrid Whitening Systems: These systems may combine in-office procedures with take-home kits to enhance and maintain whitening results. They often involve a preliminary in-office treatment followed by the use of custom-fitted trays at home.


5. Custom Tray Whitening: While primarily a take-home method, it's sometimes initiated in the dental office with the creation of custom-fitted trays. Dentists may start the process in-office to ensure proper application and effectiveness.

2. Take-Home Teeth Whitening Kits

For a more gradual approach, take-home kits allow you the convenience of whitening your teeth in the comfort of your home, with each use progressively enhancing your smile.

3. Over-the-Counter Products

Access to over-the-counter products is straightforward, providing an entry-level whitening solution. Popular options include teeth whitening strips, teeth whitening gels and teeth whitening pens. These products are the most easily accessible and cost-effective way to brighten your smile on a budget. However, they tend to be less effective than professional treatments.


When selecting your teeth whitening method, consider your desired results and how quickly you would like to achieve them.

Teeth Whitening Treatment Procedure

Before the Procedure



  • Schedule an appointment with a dentist for an initial assessment to determine your suitability for teeth whitening.
  • Discuss the best whitening method for your needs, considering your oral health and any dental restorations you may have.



  • Undergo a dental examination to identify and treat any underlying issues, such as cavities or gum disease, to ensure a clean and healthy oral base.
  • Receive a professional cleaning to remove plaque and surface stains, enhancing the effectiveness of the whitening treatment.
  • Ensure your oral hygiene is exemplary, possibly including a scale and polish, to prepare your teeth for the whitening process.

Post-Procedure Care:

  • Sensitivity Management: It's common to experience some sensitivity. Your dentist may recommend specific products to alleviate this.
  • Maintaining Results: To extend the longevity of your whitened smile, adhere to oral hygiene practices and follow the guidelines for a diet that minimises staining substances.

During the Procedure

Application Process:


  • Application Process: Following the protective covering of your gums, the whitening agent, as explained in the "How Does Teeth Whitening Work?" section, is applied to your teeth. This step utilises the bleaching properties to target and lighten discolouration effectively.
  • Activation: Depending on the chosen method, an LED or laser light may be employed to activate the gel, focusing on the practical application and immediate monitoring by your dentist to ensure optimal outcomes.
  • Duration: The entire session is closely monitored, typically concluding within about an hour, emphasising safety and comfort throughout.

Dos After Teeth Whitening:


  • Brushing twice a day and regular dental cleanings prevent surface stains.
  • As much as possible, choose clear or white beverages and foods to avoid discolouration.
  • Maintain oral hygiene with regular brushing and flossing.
  • Drink plenty of water, especially after meals.
  • Visit your dentist regularly for check-ups and cleanings.

Tooth Shade Guide

How to Use:


  • Before Treatment: Your dentist will match your current tooth shade against the guide.
  • After Treatment: Compare your post-whitening teeth to the initial shade to gauge the results.

What You'll See:

The guide typically consists of a series of porcelain or plastic teeth, arranged in a spectrum from lightest to darkest.

It categorises tooth colours in this manner:

A: Reddish-brown
B: Reddish-yellow
C: Grey
D: Reddish-grey

It uses numbers (1–4) to indicate the colour's intensity, with “1” representing the lightest shade.

B1 is identified as the brightest natural shade teeth can reach. Typically, even at their lightest, natural teeth maintain a slight yellow hue.The difference in shades before and after treatment will help you understand the level of whitening achieved.

Setting Realistic Expectations

It's important to have a realistic understanding of what teeth whitening can achieve. Not all teeth will whiten to the same degree, and the original shade of your teeth plays a significant role in the potential outcome. Here are factors to consider:


1. Intrinsic vs. Extrinsic Stains: Teeth whitening treatments are most effective on extrinsic (surface) stains caused by food, drinks, and smoking. Intrinsic stains, which are inside the tooth, may not respond as well and might require alternative cosmetic treatments, such as veneers.


2. Age and Tooth Structure: Younger teeth, with more porous enamel, tend to whiten more readily. Over time, enamel wears down, and the naturally yellower dentin underneath becomes more visible, potentially making whitening less effective.


3. Pre-existing Dental Work: Existing dental restorations like crowns or fillings will not lighten with whitening treatments, which may result in uneven shades if these restorations are on visible teeth.


Remember, the goal is to enhance your smile by improving the tone of your teeth without compromising your oral health. It is also a step to ensure that results align with your expectations

Am I a Good Candidate For Teeth Whitening?

Determining your suitability for teeth whitening depends on several nuanced factors:
  • Healthy Gums and Teeth: Crucial for whitening. Pre-existing dental issues should be addressed first.
  • Surface Stains: Stains from food, drinks, and smoking typically respond best to whitening.
  • Age and Dental Work: Younger individuals and those without dental restorations like fillings or crowns may see more pronounced results. Restorations do not lighten.
  • Sensitivity: If you have sensitive teeth or gums, discuss it with your dentist. There are solutions designed to reduce sensitivity.
  • Lifestyle: Your diet and smoking habits post-whitening affect how long the results last. Avoiding stain-causing substances is advised.
  • Expectations: Understand that results can vary. While whitening improves brightness, achieving a "Hollywood" white is not guaranteed for everyone.
Assessing these factors with your dentist can help determine if teeth whitening is a suitable cosmetic procedure for you, ensuring you achieve a brighter smile safely and effectively.

Teeth Whitening Risks

  • Sensitivity: Teeth may become temporarily more sensitive after whitening, a common issue for those already prone to sensitivity, due to whitening agents reaching the dentin.
  • Gum Irritation: Whitening products can cause temporary gum discomfort.
  • Enamel Damage: Overusing whitening products risks enamel harm. Following dental advice is key to avoiding damage.

Teeth Whitening Complications

  • Temporary Discomfort: The process may cause short-term sensitivity or gum irritation, impacting daily activities.
  • Potential for Overuse: Frequent application of whitening treatments without professional guidance can lead to complications such as enamel degradation.
  • Individual Variation in Effectiveness: Results can vary widely among individuals, with some experiencing less satisfactory outcomes or needing additional sessions for desired whiteness.

1. Can Teeth Be Whitened Permanently?

No. While teeth whitening effectively enhances smile brightness, no treatment is permanent. However, you can prolong the effects of teeth whitening by avoiding or limiting stain-causing foods.

2. How Long Does Teeth Whitening Last?

Whitening longevity varies with treatment type and personal habits. Professional treatments can last up to 3 years, with at-home methods lasting months. Regular care and avoiding staining substances are crucial.

3. Why is Professional Whitening So Costly?

Professional whitening costs more due to the use of advanced technology, higher concentrations of whitening agents, and the expertise of licensed dentists, ensuring effective, safe, and tailored treatments for optimal and lasting results.

4. Are Teeth Whitening Treatments Safe?

Yes. Teeth whitening is safe with professional oversight, improving oral hygiene and smile aesthetics. Be mindful of temporary sensitivity or gum irritation. Consultation with a dentist is vital for tailored treatments and minimising side effects.

5. Do Teeth Whitening Treatments Hurt?

No. Professional teeth whitening typically causes no significant pain, though some may experience temporary sensitivity. This discomfort is minor and short-lived, with specific care recommended to reduce it.

6. How Long Does Teeth Whitening Take?

In-office teeth whitening offers immediate effects, with full colour stabilisation in 2-3 days. Home treatments require weeks, depending on discolouration. Lifestyle impacts the duration of results.

7. How Many Sessions Does It Take to Whiten Your Teeth?

The number of whitening sessions varies by desired results and discolouration level. In-office treatments may provide instant improvement in one visit, while home kits need multiple applications over weeks.

8. Is Whitening Your Teeth the Same as Bleaching?

No. While bleaching is a type of whitening, teeth whitening can involve either bleaching or non-bleaching products.

9. How Often Should I Whiten My Teeth?

Whitening frequency should align with oral health and is determined by a dentist. Professional treatments may be recommended twice a year, with at-home product use as directed.

10. I've Tried Whitening My Teeth Multiple Times But I'm Still Dissatisfied With The Results. What Can I Do?

Consider consulting with a cosmetic dentist to explore alternative treatments like veneers or bonding. Unfortunately, you may also need to adjust your expectations as most “pearly white” smiles portrayed in popular media are the result of Photoshop and/or lighting.

11. How White Should My Teeth Be?

Set realistic expectations for teeth whitening based on genetics and natural colour. Aim for a naturally enhanced look, with professional guidance for achieving and maintaining the desired shade.

12. Can I Whiten a Single Tooth?

Yes, targeted treatments can whiten a single discoloured tooth, using either peroxide-based gels or porcelain veneers for a uniform smile. Consultation with a dentist is crucial for optimal treatment.

13. Does Whitening Work On All Teeth?

No. Whitening effectiveness varies by stain type and tooth condition. It's more successful on extrinsic yellow stains than on intrinsic or discoloured ones by medication. Options like veneers are suggested for resistant stains.

14. Can Pregnant Women Go For Teeth Whitening?

Pregnant women are generally advised to avoid teeth whitening procedures due to the lack of safety data on the effects of bleaching agents during pregnancy.

15. Can Children Go For Teeth Whitening?

Children under the age of 16 are typically not recommended for teeth whitening due to the potential sensitivity of developing teeth and gums.
