Teeth Whitening is increasingly popular in Singapore as many seek to enhance their appearance and boost their confidence. With the growing demand for safe and effective teeth whitening solutions, we offer a number of treatment options to help you present the best version of yourself.

Understanding Teeth Whitening

Teeth whitening is a cosmetic and non-invasive dental treatment that removes stains and discolouration from your teeth. This can be done in two ways — professional whitening or at-home teeth whitening kits.

The treatment offers a boost in your confidence, leading to a positive impact on social interactions. The process can remove deep stains, reducing the risk of cavities and gum disease. It can contribute to better oral hygiene habits as individuals tend to be more motivated to maintain post-whitening care following the procedure.

Additionally, teeth whitening can be a convenient and effective way to achieve a whiter smile that lights up your face.

2 Teeth Whitening Treatments for Every Smile

1. In-House Whitening (ZOOM)

A quick and effective way to achieve a brighter smile, our in-clinic whitening treatment or chairside teeth whitening is performed by our expert dentists, ensuring safety and remarkable results.

  • Duration: Approximately one hour.

  • Application Method: Professionally applied whitening gel, activated by Zoom lamp light or high-intensity UV light.


  • Immediate and noticeable results after just a single session.

  • Supervised by dental professionals for a safe treatment process.

  • Customisable treatment intensity to match individual sensitivity and need.


  • Higher cost compared to at-home options.

  • Potential for temporary teeth sensitivity.

You might benefit most from in-office teeth whitening if you seek immediate results, desire professional guidance and supervision, have severe or deep stains, or have busy schedules.

2. Home Whitening Kit (Opalescence teeth whitening system)

For those who prefer the convenience of home, we offer custom-fitted whitening kits tailored to your dental profile for effective and comfortable treatment.

  • Duration: Use daily for two weeks.

  • Application Method: Custom-fitted bleaching trays filled with whitening gel.


  • Flexibility to whiten teeth at your pace and comfort.

  • Custom trays ensure even application and minimise gum irritation.

  • Professional quality results in the comfort of your home.


  • Requires commitment to daily application.

  • Results appear gradually over the treatment period.

At-home whitening is best suited if you want flexibility in the whitening process or prefer a gradual improvement in the brightness of your teeth. It is also ideal for people with busy schedules who may not have time for in-office treatments, allowing them to undergo whitening at their convenience.

What Causes Teeth Stains?

Teeth stains refer to the darkening or yellowing of teeth beyond their natural shade. This may occur over time due to various factors, leading to discolouration. However, teeth stains can be effectively removed or lightened through teeth whitening treatments. 

Categorised into two main types:

  • Extrinsic stains

  • Intrinsic stains

Type of Tooth Stain


Caused By


  • Affects the outer surface (enamel) of the tooth, appearing as surface discoloration.
  • Discolour your tooth enamel, which may absorb some of the colour of the items you consume.
  • Extrinsic stains cling to dental plaque.
  • Extrinsic stains are easy to remove as they are located on the tooth surface.
  • Food and beverages that contain staining agents: Coffee, tea, wine, soda, dark fruits, and vegetables 
  • Tobacco and alcohol use
  • Poor oral hygiene: Plaque buildup


  • Affects the inner structure (dentin) of the tooth, causing discoloration throughout the tooth.
  • Dentin is naturally darker and more yellow than enamel.
  • Dentin is exposed when the enamel thins out due to wear and tear or inadequate oral hygiene.
  • Intrinsic stains are a little tougher to remove, but professional whitening can whiten it.
  • Aging: Natural yellowing of dentin
  • Genetics: Conditions known to cause inherent staining in teeth like dentinogenesis imperfecta
  • Certain medications: Tetracycline, antihistamines, antibiotics, certain mouthwashes
  • Excessive fluoride exposure: During childhood development 
  • Tooth injury or trauma: Cracks, fractures

Finding Your Perfect Smile: Choosing the Right Treatment

Choosing the right whitening treatment is a decision that should align with your smile goals. We take a personalised approach to help you select the best option, considering several key factors:

  • Desired Level of Whitening. Whether you are looking for a subtle enhancement or a dramatic transformation, we tailor our recommendations to meet your expectations.

  • Lifestyle and Preferences. Your daily routine and personal preferences play a significant role in selecting the right treatment. We consider factors such as the convenience of treatment and the pace at which you wish to see results.

  • Budget. We believe everyone deserves a radiant smile. Our team works diligently to offer options that accommodate various financial considerations, ensuring you don't have to compromise on quality.

  • Teeth Sensitivity. For those with sensitive teeth, certain treatments may be more suitable. Our dentists will assess your dental history to recommend the most comfortable and effective solution for you.

Your Teeth Whitening Journey: From Consultation to Aftercare

Our dentist will discuss your dental history, goals, expectations, and any concerns you may have. This is a great opportunity to ask questions and express what you're hoping to achieve with teeth whitening. Our dentist may conduct a thorough examination to assess and evaluate your oral health and to determine if you're a suitable candidate for the procedure.

Based on the outcome, our dentist will develop a personalised treatment plan and recommend the most suitable whitening option for you, ensuring that the chosen treatment aligns perfectly with your needs.

Treatment Options - Teeth Whitening Process

If you opt for in-office teeth whitening, here's what to expect:

  1. Our dentist will isolate your gums and lips with a protective barrier (a rubber coating) to ensure your safety throughout the procedure.

  2. A peroxide-based bleaching agent is then carefully applied to your teeth. The whitening gels may be in multiple applications throughout the procedure, depending on the desired results.

  3. After the application, a special LED light or Zoom lamp light may be used to activate the whitening gel and accelerate the whitening or bleaching process.

  4. Next, our dentist will remove the gel and rubber coating, polish your teeth, and provide you with aftercare instructions.

  5. Additional office visits would be scheduled until the desired shade is achieved.

The procedure normally takes 45 minutes to an hour, delivering immediate results. Our dentists utilise a professional-strength bleaching agent with a higher whitening content, ensuring an effective and efficient treatment process.

If you choose take-home whitening kits, the process involves:

  1. Our dentist will take impressions or moulds of your teeth to create custom-made trays that comfortably fit your mouth and hold the whitening gel.

  2. You'll be given detailed instructions on how to apply the bleaching gel (usually carbamide peroxide) and use the whitening trays at home, giving the flexibility to whiten teeth at your own pace and convenience. Proper cleaning and storage of the trays are also important to ensure their effectiveness.

  3. You'll wear the trays for a specific time frame daily, typically for a few weeks, or as recommended by our dentist to achieve the desired level of whitening.

  4. Follow-up appointments may be scheduled to check your progress and make any necessary adjustments to your treatment plan.

Results may only be seen after two to three weeks of consecutive use.


Whichever teeth whitening option you choose, post-teeth whitening care is crucial for prolonging the beautiful results.

Below, we have outlined essential aftercare recommendations to help you maximise the benefits of your whitening treatment.

Maintaining Your White Smile After Treatment

To ensure your teeth remain as bright as the day you left our clinic, consider the following aftercare tips:

  • Maintain a strong oral routine. Brush your teeth at least twice a day and after meals, and floss daily to remove plaque and prevent tooth decay.

  • Avoid teeth-staining food and drink. Limit consumption of coffee, tea, red wine, dark-coloured fruits, chocolate, and sauces. Essentially, avoid anything that could potentially stain your teeth.

  • Avoid acidic, sugary, and chewy foods as they can cause damage to the tooth surface.

  • When consuming beverages, using a straw can help reduce contact with your teeth, thus preventing staining.

  • Rinse after eating and drinking. If you can't brush immediately after eating or drinking, use mouthwash to minimise potential staining.

  • Incorporate a whitening toothpaste into your dental routine for daily maintenance and to tackle surface stains.

  • Steer clear of tobacco and alcohol. Smoking and drinking can quickly reverse the effects of your whitening treatment.

  • Stay hydrated. More water intake can help prolong the whitening effects on your teeth.

  • See your dentist once every six months for routine cleanings to keep your teeth healthy and your smile bright.

  • Schedule regular touch-up appointments. You might need touch-ups every six months.

Are teeth whitening results permanent?

While teeth whitening treatments significantly improve the brightness of one's smile, their effects are not permanent (meaning this can fade over time). Teeth whitening can last for about months to years, but the results may vary from person to person. The longevity of whitening depends on your lifestyle choices and maintenance habits.

We recommend maintaining good oral hygiene and getting professional touch-up treatments to prolong the results. You can talk to a professional dentist about when to touch up your whitening treatment to keep your teeth looking their best.

Will teeth whitening cause sensitivity?

Yes, teeth whitening can cause sensitivity. It's common to experience tooth sensitivity after teeth whitening treatment, usually of a mild and short-lived nature.

If you have previously experienced sensitivity following whitening or have sensitive teeth, it is advisable to discuss it with your dentist beforehand. They can assess your oral health and suggest the best treatment option for you.

Can teeth whitening be done on crowns or veneers?

Generally, teeth whitening treatments mainly impact natural tooth enamel and do not change the colour of any dental restoration. These are made from materials that do not respond to the bleaching agents in whitening products.

However, tooth whitening can still be done if you have crowns or veneers. The whitening will just lighten and remove stains from your natural teeth, resulting in a whiter shade than dental veneers or crowns. This may lead to an uneven appearance in your smile.

If you have these restorations, we can advise on the right approach to ensuring your smile remains uniformly bright, possibly including replacing older restorations after whitening procedures.

How long does teeth whitening last?

The duration of teeth whitening effects can vary widely; on average, it can last up to three years. However, it depends on a number of factors:

- the type of teeth whitening treatment;
- the degree and type of stain or tooth discolouration that you have;
- your lifestyle, including diet and habits;
- the frequency of dental check-ups;
- oral care routine; and
- even your age and genetic makeup.
As every patient and every case is

 different, our dental clinic is committed to providing tailored methods to extend the life of your whitened smile.

Are there any side effects of teeth whitening?

When carried out by a qualified dentist, teeth whitening procedures are generally safe and painless and considered non-invasive. However, like every other dental treatment, it can potentially cause temporary side effects.

Most patients experience mild tooth sensitivity or gum irritation due to the bleaching properties used in the process. These symptoms typically subside within a few days to a week after the treatment, and the discomfort is often temporary and should fade over time.

If you undergo teeth whitening treatment with us, our dentists ensure the safety standards to minimise potential discomfort and risks for our patients.

How white should my teeth be?

Stained teeth or yellow teeth can be improved, regardless of what teeth whitening options you choose to achieve whiter teeth. However, the desired level of whiteness ultimately depends on your personal preferences and the dentist's recommendations. Consider your skin tone, the white part of your eyes, dental stains (or surface stains), and if you have any existing dental work.

In the course of your consultation, our dentists will discuss your aesthetic goals to recommend a whitening level and perfect shade that will look both stunning and natural on you.
