Teeth Whitening In Singapore

Having a row of whiter teeth can help to increase your confidence and overall appearance. Yellowish teeth, on the other hand, could have an adverse effect, often diminishing one’s self-esteem.

Persistent stains or a yellowish tinge on the teeth sometimes cannot be removed with simple dental scaling and polishing. Such deep stains require a more potent approach, which can be addressed and gently removed through professional teeth whitening procedures conducted by a trained dentist.

What Is Teeth Whitening?

Teeth whitening is a specialised dental procedure in Singapore that employs peroxide-based bleaching agents to break down and dissolve stubborn stains, offering a level of whitening that over-the-counter whitening kits cannot match. This professional treatment, exclusively performed by trained dentists, not only revives the brightness of your smile but also targets surface discolourations caused by coffee, tea, cigarettes, and wine, among other lifestyle factors. Beyond aesthetic improvement, teeth whitening can also contribute to oral health by eliminating bacteria that linger in plaque and gum pockets, promoting a cleaner and healthier mouth.


Teeth whitening services in Singapore are not just cosmetic enhancements; they are professional dental treatments. Beginning with a detailed consultation, your local dentist will evaluate the condition of your teeth to craft a personalised whitening strategy that aligns with your dental characteristics and aesthetic aspirations.

The heart of the treatment lies in the application of peroxide-based bleaching agents that delve beneath the enamel, targeting and oxidising the deep-seated stains that disrupt the natural whiteness of your teeth. Customised to each individual’s needs, the concentration of peroxide and the duration of its application may vary depending on the severity of discolouration and the desired outcomes.

It’s important to note that the most dramatic results are seen on teeth with a yellowish hue, as the procedure is specifically optimised for such cases. Brown or grey-toned stains might not respond as well. Additionally, teeth whitening does not affect the colour of dental restorations such as caps, veneersdental implants and crowns, or fillings. Discolouration resulting from medications or trauma might also not be amenable to the whitening process.

Typically, the teeth whitening procedure will be completed within an hour. It commences with the application of a gum-protective gel, followed by the careful application of a hydrogen peroxide-based whitening agent by a trained dentist onto all visible surfaces of your teeth Depending on the selected procedure, an activating light might be employed for around 15 minutes to enhance the teeth whitening gel’s properties. Throughout this process, comfort and customisation are paramount, ensuring a pleasant experience leading to a brighter smile.

Types of Teeth Whitening Treatments

Take-Home Teeth Whitening Kit

Home kit whitening is designed for ease and personalisation, offering a tailored solution to your teeth whitening needs. Afterwards, your dentist will provide you with a customised tray meticulously crafted to fit snugly over your teeth. Depending on the intensity of whitening desired, solutions of varying concentrations are applied within these trays, which can be worn either overnight or for specific intervals throughout the day, typically over a two-week period. This flexibility allows you to integrate the whitening process seamlessly into your daily routine with minimal disruption to your schedule.

The convenience of home kit whitening lies not only in its adaptability to personal timetables but also in its potential for a more controlled and gentle whitening journey. As the treatment unfolds, the custom-fit trays ensure consistent exposure of your teeth to the whitening agent, promoting even and effective lightening. While the process may be more gradual compared to in-chair procedures, it is particularly well-suited for those with mild to moderate discolouration, patiently edging towards the desired outcome. Nevertheless, the effectiveness of home kit whitening is dependent on individual dental characteristics and adherence to the prescribed regimen. A thorough consultation with a dental professional can help to increase the efficacy of this process, allowing for a well-informed and optimally beneficial teeth whitening experience.

Chairside (In-Clinic) Teeth Whitening

Chairside whitening is a sophisticated in-clinic procedure that utilises advanced technology to achieve a brighter smile in a relatively short period. The procedure typically employs LED or laser technology to enhance the efficacy of the whitening gel applied to the teeth. This activation process, divided into three segments of approximately 20 minutes each, can accelerate the bleaching effect, which may enable significant shade improvement within just one visit.

To ensure patient safety and optimal results, the chairside whitening procedure will be executed by professional dentists. They are skilled in applying the precise concentration of whitening gel and adept at controlling the light source to prevent any potential damage to the tooth enamel or gum tissue. Moreover, dentists can provide immediate assistance and remedies in case of any sensitivity or discomfort, making chairside whitening a reliable and preferred choice for rapid and noticeable teeth whitening.

Chairside Teeth Whitening Process

The teeth whitening process begins with a dental assessment to identify the underlying causes of tooth discolouration. This assessment helps the dentist determine the most appropriate treatment plan for each individual.

In-chair teeth whitening treatments typically involve a series of steps. Prior to the procedure, routine scaling and polishing may be performed to enhance the contact between the teeth and the bleaching agent. The dentist will then apply the whitening gel onto the teeth, which will be activated so that it can break down the stains and lighten the tooth colour. Depending on the initial condition of the teeth, a few sessions may be required to achieve the desired level of whitening.

Causes of Teeth Discolouration

Teeth discolouration is a common issue that affects many individuals, including those in Singapore. It can result from a variety of causes, which can generally be categorised as extrinsic or intrinsic factors. Extrinsic causes refer to external factors that stain the surface of the teeth, while intrinsic causes pertain to changes within the tooth structure that affect the colour of teeth.

Extrinsic Causes

Extrinsic causes of teeth discolouration include the consumption of certain foods and beverages. Common culprits are wine, coffee, and tea, which are known for their staining properties. These items are often consumed regularly and can lead to the gradual staining of the teeth’s surface. Additionally, the use of tobacco products is a significant contributor to extrinsic stains on the teeth.

Intrinsic Causes

Intrinsic causes of teeth discolouration are related to factors that affect the internal structure of the teeth. One of the intrinsic factors is the natural ageing process, which can cause changes to the dentin, the inner tissue of the tooth, leading to a darker or yellowish appearance. This type of discolouration can also be exacerbated by prolonged exposure to acidic foods, which can erode the enamel and expose the darker dentin underneath.

Another intrinsic factor that can cause discolouration is the damage caused to a tooth’s outer layer due to aggressive brushing or tooth root infections. Aggressive brushing can wear away the enamel over time, and infections can cause discolouration from the inside out.

Do’s and Don'ts After Teeth Whitening

For a smooth teeth whitening experience and to minimise the risk of possible side effects, it is crucial to follow these guidelines:

  • Do seek the advice and guidance of a trained dentist before undergoing any teeth whitening procedure to ensure a proper assessment and personalised treatment.
  • Do not attempt teeth whitening without consulting a dentist.
  • Do follow the dentist’s instructions carefully when using at-home whitening kits or in-office treatments.
  • Do not use unregulated or over-the-counter whitening products without professional guidance.
  • Do report any discomfort or side effects to your dentist promptly.

After your teeth whitening treatment, it is essential to follow proper post-treatment care to maintain the results and promote oral health. 

  • Avoid consuming dark-coloured foods and beverages (e.g. red wine, tea, coffee, curry, green spinach, etc.), as well as tobacco products, which can stain the teeth.
  • Use toothpaste specifically formulated for sensitive teeth, if necessary, to minimise any tooth sensitivity that may occur.
  • Practise good oral hygiene by regularly flossing, brushing your teeth twice daily, and scheduling routine checkups with your dentist.
  • If recommended by your dentist, consider using touch-up kits or undergoing periodic touch-up treatments every nine to 12 months to maintain the whitening results.

Potential Risks of Teeth Whitening

Teeth whitening is a popular cosmetic procedure in Singapore, but it is not without potential side effects and risks. Patients should be aware of these possible complications before undergoing teeth whitening treatments.

Tooth Sensitivity

One of the primary risks associated with teeth whitening is an increase in tooth sensitivity. This is particularly the case for patients who already experience sensitive teeth. The whitening agents can penetrate the tooth enamel and reach the dentin layer, which contains the nerve fibres. This process can exacerbate sensitivity, causing discomfort during and after the treatment.

Gingival or Mucosal Irritation

The chemicals used in teeth whitening solutions may also pose a risk to the gums, potentially leading to irritation or ulceration. This occurs when the whitening product comes into contact with the gum tissue (gingiva) or the mucous membranes in the mouth, leading to a chemical burn or irritation. It is essential that the whitening agent is applied carefully and that any excess is removed promptly to minimise this risk.

Mild Discomfort and Pain

In addition to sensitivity and irritation, teeth whitening can sometimes lead to mild discomfort and pain in the teeth and gums. This discomfort is usually temporary and often occurs as a result of the bleaching agents used during the procedure, which can cause a mild inflammatory response in the dental nerves. For some individuals, this pain can be a deterrent from undergoing or repeating the whitening process. It’s important for patients to discuss pain management options with their dentist prior to starting treatment, which may include the use of desensitising products or pain relief medications to help manage any discomfort that arises after the whitening session.

Frequently Asked Questions About Teeth Whitening in Singapore

Teeth whitening is not recommended for children under the age of 16. This is because the pulp chamber, or nerve of the tooth, is enlarged during this age. Teeth whitening done on children under the age of 16 could cause their teeth to become sensitive. 

Individuals with sensitive teeth and gums, receding gums and/or defective restorations should consult their dentist prior to using a tooth whitening system. Anyone allergic to peroxide (the whitening agent) should also not use a bleaching product.

It is advisable that teeth whitening is done only on patients with healthy teeth and gums. This means that there should not be any gum problems and that the teeth should be decay-free, or the patient may experience irritation to the gums and teeth. In addition, before any whitening is done, the teeth should be plaque/tartar-free so that the whitening gel can be in direct contact with the teeth. As such, dental scaling and polishing by a dentist needs to be done beforehand.

Teeth that exhibit uneven discolouration might present challenges to teeth whitening procedures, potentially leading to inconsistent or patchy results. Areas of the teeth that are discoloured differently may respond at varying degrees to the whitening process, which could accentuate the unevenness instead of correcting it. Additionally, it is important to recognise that teeth whitening treatments are ineffective on dental restorations such as crowns, veneers, and fillings. These materials dounding natural teeth become whiter, potentially leading to a mism not respond to bleaching agents as natural tooth enamel does, so they will remain unchanged while the surroatched appearance.

For more information on teeth whitening, refer to our guide on the six essential things to know about teeth whitening in Singapore.

The ideal whiteness for your teeth is subjective and should complement your features. We recommend avoiding an unnaturally white shade that could look synthetic. A dentist can guide you to a shade that is both aesthetically pleasing and looks natural. This decision is influenced by factors such as your skin tone, facial features, and personal preferences. The aim is usually to achieve a balance where your teeth appear naturally white without being distracting or seeming out of place.
The time it takes to see results from teeth whitening varies depending on the method used. In-chair treatments may provide very apparent results on your teeth, appearing several shades lighter after just one session. Home kits typically require consistent application over a period of days or weeks. Results can be gradual and may vary based on the degree of discolouration and individual tooth response to the whitening agent. It’s important to have realistic expectations and to follow your dentist’s instructions for the best outcome.

At-home treatments usually involve using special bleaching trays fitted to your mouth and filled with a professional-grade hydrogen peroxide bleaching gel. With this method, you might be able to see more lasting results after six to nine months.

When getting teeth whitening done through a dental practitioner, you’ll have access to stronger concentrations of bleaching agents. The effects of a chairside teeth whitening session performed in various clinics across Singapore will typically last anywhere from six months up to four years but may depend on factors such as lifestyle choices (e.g. excessively drinking coffee) and oral hygiene habits (e.g. proper brushing). 

If needed, touch-ups can always be done down the line, so don’t worry if there are slight signs of discolouration showing up again over time, these can be addressed via another exam with your dentist.

Permanent teeth Whitening is not currently possible. All whitening procedures may need to be repeated over time to maintain the brightness of your teeth, especially if you consume staining foods or drinks or if you smoke. Good oral hygiene and occasional touch-ups may help in prolonging the effects, but the natural ageing process and lifestyle choices will eventually affect the colour of your teeth again.
If repeated whitening treatments do not yield satisfactory results, it may be time to discuss alternative options with your dentist. Some teeth do not respond well to whitening due to deep intrinsic staining or other factors. In such cases, your dentist might recommend more permanent solutions such as dental veneers or crowns, which can provide a consistent and long-lasting tooth colour that whitening alone cannot achieve.
Teeth whitening is generally considered safe when performed or prescribed by a dental professional. The key to safety is in the professional assessment of your teeth’s suitability for whitening and the proper use of whitening agents. Side effects may include tooth sensitivity and gum irritation, but these are usually temporary. It’s critical to use products approved by dental health authorities and to follow your dentist’s instructions to minimise risks. Regular checkups and consultations can assist in ensuring that your teeth whitening process is both effective and safe.
Generally speaking, professional teeth whitening done by an experienced dentist is less likely to cause any pain or discomfort for most patients when performed correctly. At-home bleaching systems are also considered relatively mild and often do not cause any pain or irritation at all. Any sensitivity in your gums or teeth, side effects usually only last for a few days afterwards with no other long-term problems.
  • Avoid dark-coloured foods and beverages, as well as smoking for at least a week after whitening. Whenever possible, sip dark-coloured beverages with a straw.
  • For touch-up kits, apply the gel into the custom trays and insert them over your teeth over five days for five to seven hours per day. You may wish to wear the trays overnight for convenience. After you have completed the touch-up procedure, you may store the remaining gel in a refrigerator. You may wish to repeat the touch-up procedure every six to nine months or for three days before an important event for which you wish to have whiter teeth. (Whitening gel refills may be purchased at your chosen clinic in Singapore).
  • To keep your teeth looking their best, we recommend flossing, brushing twice daily, and scheduling a six-month routine checkup with your dentist.
