The cost of teeth whitening in Singapore ranges between $800 to $1,300. Teeth whitening treatments in clinics generally are much more expensive than salon and take-home kits. In a salon, teeth whitening procedures generally cost around $180 to $500. Take-home kits for teeth whitening in Singapore are much cheaper and cost between $18 to $60.  

Teeth whitening has come a long way since its inception. At first, it was carried out with stuff that sits around in the house like baking soda. And now it’s gotten to a point where you can pay a teeth whitening specialist at a dental clinic in Singapore to do it professionally with the help of expensive high-grade equipment. There is a lot of controversy around these options - which one is better, are they safe, which is more better at whitening teeth? - and we are here to shed more light on both. Stick around to find out more about home-based teeth whitening and in-office teeth whitening methods in Singapore.

Why Do Teeth Discolour Over Time?

To explain this, let’s start with some basic facts about the tooth structure. Nerves and blood vessels are wrapped up in something like a shell that keeps them from damage. To begin with, they are encased in the dentin, which protects against infection and happens to be yellow in appearance. This layer is less mineralised and tends to form throughout life.

Above it lies the enamel. Although relatively durable and thick, it’s less sturdy than the dentin, making it prone to chipping. In fact, this is the outermost layer of the teeth and the main culprit for the shade of your smile. But it’s not because of the colour. Technically, the enamel is translucent, so there is little it can do about the look you covet about (at least not without some external assistance). Rather it’s the exposure to different environments that alters its appearance.

It serves to shield off the structures from impact and extreme temperatures the same way a coat keeps you from the cold. Without it, every sip and bite would cause irreversible damage.

Now, when parts of the enamel wear off over time, the dentin can show through and that’s one reason for the problem.

Another one is poor oral hygiene. When you don’t wash your teeth right, plaque builds up inside the mouth, which later results in tartar. They can both make your white structures yellowish. The good news is that once you get rid of them, you will restore the shine of your pearls.

The third and commonest reason is your habits. For the most part, it’s things like ketchup, coffee, tea, wine, and other offenders that contribute to the problem. Eating curry and smoking takes a toll too. The general rule of thumb is: if it stains your tongue, chances are it will stain your teeth.

Finally, some diseases and treatments might influence how your smile looks from within.

What Are Some DIY Teeth Whitening Methods?

Let’s admit it, you can’t always cough up an amount as high as $700 for an in-office teeth whitening session at dental clinics in Singapore. That’s why most people prefer to try some at-home techniques first. Here are the different products and tools you can have for whitening of teeth if you are willing to stick with the over-the-counter options. Some even boasts effects up to 8 shades whiter.

  • Teeth whitening toothpaste or gel

What is the secret here, how does it actually help in teeth whitening, you would ask? Well, it comes with a chemical that sticks to the teeth, making it seem as if they are whiter than usual. The substance goes under the name blue covarine. If you use the teeth whitening toothpaste or gel long enough, say six weeks, you will notice some changes. However, keep in mind that toothpaste only works on the surface stains and won’t treat any spots or discoloration lodged underneath the enamel.

  • Hydrogen peroxide

This chemical compound has universal application, both around the house and on the medical scene. In small doses, it can have a nice effect on your white structures, but you should be extra careful with it. Pick a bottle of the solution at a 3% concentration just to be in the safe zone. Soak your toothbrush in it and apply directly on the teeth, brushing your way in and out. Rinse with water to ensure all debris is gone.

Another way to go is to mix one part of hydrogen peroxide with one part water. Use as a mouthwash for 30 seconds. Make sure you don’t swallow any of it because it can burn your throat and organs.

  • Activated charcoal

The powder can be employed to brighten your smile naturally. All you have to do is get your hands on one of those small pots, immerse your toothbrush in it so it catches on the tiny particles, and then wash your teeth as normal. Don’t get intimidated by how tinted everything will look. Once you rinse your mouth, those pearly whites will immediately show.

  • Gum

The market has an abundance of gum choices to suit all tastes, literally. Instead of going for your regular piece of gum, try a teeth whitening one this time around. It comes with mild abrasive properties, which help to clean gunk and remove existing stains, as well as a chemical called sodium hexametaphosphate. This buddy will make sure you don’t develop any future stains.

  • Strips

There are some over-the-counter teeth whitening strips that you should apply for a set period of time. They contain varying bleaching agent concentrations. Aside from that, some of these teeth whitening strips also have tiny amounts of hydrogen peroxide which we already discussed above.

Here is what you ought to consider before buying anything for home use. First of all, check if it's approved by dentists in Singapore and that it meets the established safety standards. Second, always read the instructions before applying.

  • Home whitening kits

A home whitening kit may vary from brand to brand. They generally come with an universal mouth tray where teeth whitening gel is applied. You then place the mouth tray into your mouth and let the whitening gel do the work. Many like the convenience of teeth whitening kit where you can do your whitening treatment at the comfort of your own home. It is commonly reported that users see 2 to 8 shades lighter in using these products.

Similar to home whitening kits, there are also take-home teeth whitening kits by dental clinics in Singapore that provide you with a mouth tray that is customised to your teeth. This will ensure optimum comfort and safety. The whitening gel that come with the take-home whitening kit can then be applied. They usually contain hydrogen peroxide, which is the main substance that removes discolorations and stains and makes your teeth white.

  • Non-peroxide teeth whitening products

Non-peroxide teeth whitening has been growing in popularity in recent times. While these gel products can still help in removing surface stains, the results can be very limited because they are not able to remove deep discoloration inside the enamel structure, due to being "peroxide free" or "non-peroxide".

What are the Advantages and Disadvantages of DIY Teeth Whitening Treatments?


  • DIY whitening treatment is affordable - there are no dentist fees involved.
  • It is convenient because you can do it at your leisure or whenever you feel like it. You don’t have to book an appointment at a dental clinic. Conforming to their visiting hours might interfere with your schedule and cause inconveniences that you weren’t prepared for.


  • When you are performing a home teeth whitening treatment, you run the risk of doing things incorrectly. For instance, you might apply the product at the wrong time or keep it on for longer than necessary, which will compromise the results. What’s worse is it may even cause structural damage.
  • That leads us to the next point, which is safety. DIY products and devices are not as good as the professional ones but that doesn’t mean the risk of messing up is smaller. On the contrary, since you are not a professional, you will not know what to do, nor will you have the experience required for a quality performance.
  • It’s not nearly as effective as professional whitening treatments. You won’t yield the same results as you would if you were to have the procedure done by a medical expert using premium equipment. So, when you face the outcome, it might make you upset.

What Does Professional Teeth Whitening Treatment Singapore Comprise?

When you undergo in-office teeth whitening treatments in Singapore, they will place a retractor (small plastic device) on your lips to keep them out of the way. A barrier will cover your gums so they are safe from damage too. When this step is over, the dentist will apply a whitening agent (hydrogen peroxide or carbamide peroxide) on the teeth and leave it on for 60 minutes. Results can be evident in a single session.

Depending on your condition, your dentist may recommend you a take-home teeth whitening kit. The teeth whitening gel or solution that come with the take-home kit may either contain hydrogen peroxide or carbamide peroxide at individualised concentrations. This take-home system of whitening treatment is a great way for individuals who cannot commit time for regular in-clinic sessions in Singapore to achieve that pearly-white smile!

What Are the Advantages and Disadvantages of Professional In-office Treatments in Singapore?


  • The effects of the treatment will last over a long period.
  • You will be served by a professional, which gives you safety and peace of mind.
  • They will stick with high-class tools to get the job done.


  • These procedures come with a heavy price tag, which involves the cost of the equipment, the dentist’s fees, and the product itself - if such is necessary.

What Are Some Concerns Regarding Both?

In general, whichever method you go by for tooth whitening, there is always a risk of developing teeth sensitivity for some time after the treatment, however, it’ll diminish fast. Now, you may also come to experience gum irritation which will go away after the manipulation ends.

That being said, getting your professional teeth whitening treatment from dental clinics in Singapore is so far a better option because it is administered in a medical setting by a person who knows what they are doing. The concentrations they use are all predetermined based on each individual case. Not to mention, the equipment is finer and more powerful, which allows for greater results. Lastly, the chance of developing side effects is slim to none.
