Teeth Whitening 

For many Singaporeans, having a great smile is a crucial part of their overall appearance and teeth whitening plays a major role in bringing out a perfect smile.

The whiter your teeth, the brighter your smile, boosting your confidence by making you look pleasant and attractive.

With the help of our dentists, you can achieve results that will be faster, easier and more effective than any consumer-grade teeth whitening tool available in Singapore.

In one visit to Gentle Smile Dental Studio, you can whiten your teeth and bring out a more confident, pleasant and gentle smile. Book an appointment with us now.

Why Are My Teeth Yellow?

Your teeth could have intrinsic stains or extrinsic stains.

Intrinsic stains 

Intrinsic stains can look white, chalky, brown or grey-black. They are stains that are embedded into the teeth while they are developing or while those teeth have erupted.

Aging also causes intrinsic staining as layers of enamel are lost over time, and the darker portions of teeth get exposed.

Extrinsic stains

Your choice of food, diet and habits plays a big part in extrinsic staining of teeth and they are the most common reason for teeth yellowing in adulthood. Major contributors of lifestyle habits include drinking coffee, tea, red wine, and smoking.

Extrinsic staining refers to stains that embed themselves on your teeth’s exterior or penetrate your tooth’s enamel. 

Most of this staining is caused by the interaction of pigments from food and beverages with the plaque covering the enamel surface. 

When stains penetrate the microscopic cracks and fissures of the teeth, they cannot be easily removed by consumer-grade whitening agents or brushing.

Why Do Teeth Whitening with Gentle Smile Dental Studio?

At Gentle Smile Dental Studio, we can help you whiten your teeth with specialised tools that are exclusive to dental professionals.

We offer a comprehensive and tailored approach that is safer, more effective, and longer-lasting results compared to over-the-counter methods.

Customised Treatment

Our dentists can provide home-based whitening treatments that utilise custom-fabricated dental trays to deliver the whitening agent.

This ensures a better fit and more effective coverage of the teeth, hence it’s more efficient in helping you whiten your teeth.

Our dentists can discuss your personalised treatment, set realistic goals, and make you aware of the process including what to watch out for. We will also answer any questions that you have.

Prescription-grade Whitening Agents

In-office procedures often use higher concentrations of hydrogen peroxide (25%-45%).

This can produce faster and more dramatic results compared to over-the-counter products. 

In contrast, over-the-counter whitening agents used in unregulated kits have a maximum concentration of 0.1%. 

The low concentration avoids any severe problems that come from user error, but this is far too low for any meaningful effect.

Since dentists like us have specialised tools, therefore, you can get whiter teeth in less time.

Professional Cleaning Before Whitening

To maximise effectiveness of our cleaning treatments, we can help you clean your teeth and remove any plaque to ensure that the teeth whitening treatments are working directly on your teeth

Our Teeth Whitening Methods

Sometimes, brushing is not enough!

We recommend two types of teeth whitening methods.

In-Office Chairside Whitening

Whitening your teeth can make you look and feel more confident. It’s an easy process that just takes one visit to our dental clinic, where we will apply trays of gel firmly onto the teeth surface over the next hour until they look several shades lighter and brighter.

Take-home Kits

For patients who are looking for take-home kits, we offer an alternative effective maintenance program that will keep the colour of your teeth white.

In-clinic treatments provide faster and potentially more dramatic results.

Fast results

You will see immediate results on the same day as your treatment. In about an hour, you’ll notice your teeth whiten significantly. 

Professional protection

Our dentists will take utmost care to protect your gums from whitening agents by using dental dams or protective gels.

Tackles deeper staining and yellowing

Chairside whitening remains the only option if your teeth are significantly stained beyond what a take-home, prescription-grade kit can help.

You might prefer a take-home kit because

  • you don’t need immediate results;
  • prefer the flexibility;
  • your take-home kit can be used multiple times in the future.

Patients can continue to whiten their teeth until they reach their desired shade.

Moreover, after the initial treatment, you will still have the trays and access to the whitening material, allowing them to touch up their smile as often as they like. 

Lower Costs

The cost of a take-home kit is lower than an in-clinic teeth whitening experience.

Custom Trays

These trays are custom-fabricated to fit your teeth perfectly so that the teeth whitening agents make contact with your teeth and ensure effective teeth whitening.

Teeth Whitening Timelines

Come to Gentle Smile Dental Studio for a consultation prior to your treatment for a safe, effective teeth whitening experience.

No matter which teeth whitening option you choose, we’ll meet two weeks after the treatment for a review.

In-Office Chairside Whitening

Firstly, we’ll have a 30 mins consultation.

Then, you choose between the Express and Premium package.

Express package: 45 mins consisting of two whitening cycles

Premium package: 1 hour consisting of three whitening cycles

Each cycle will consist of these steps:

  1. We’ll polish your teeth
  2. We’ll use a retractor and barrier to keep lips and gums away.
  3. We’ll apply the whitening gel 
  4. We’ll shine teeth whitening light 

After each cycle, we will replace the whitening gel and shine the light again for the next cycle.

Take-Home Kits

If you prefer a take-home teeth whitening kit, we will then use the digital scan from the consultation to fabricate whitening trays which means no need for mould/dental impression.

Trays will take 10 days to 2 weeks to be ready. 

Our Gentle Smile team will test the trays to ensure fit and to teach you how to apply the gel and give instructions for usage.

Take-home teeth whitening kits are used for 1-2 hours each day for two weeks.

Frequently Asked Questions

What is the cost of treatment?

The cost of treatment ranges from $350 to $950.

How quickly can this treatment be done?

For take-home teeth whitening, it will take about two weeks. For chairside teeth whitening, your results will be seen on the same day. There is also a two-week follow up for all teeth whitening treatments.

What is the difference between in-clinic chairside teeth whitening and take-home teeth whitening kits?

Both methods are effective in helping you whiten your teeth as they both use prescription-grade teeth whitening agents under the supervision of our dentists. The main difference between chairside teeth whitening and take-home kits is the time needed to see results, prices and your involvement in the process.
