Category: Teeth Whitening

Teeth whitening is now the most commonly requested cosmetic dental procedure1.  With greater demand for cheaper and more convenient teeth whitening products, many have resorted to buying teeth whitening products online as well as trying numerous do-it-yourself (DIY) methods using natural ingredients like strawberry puree, etc.

There are 4 options for teeth whitening:

  1. In-office whitening
  2. Take-home whitening
  3. Over-the-counter (OTC)
  4. Non-dental options
1. In-office whitening

In-office teeth whitening is done by the dentist in the clinic and this involves the application of a hydrogen peroxide bleaching gel. These whitening agents penetrate your teeth to break down the discoloured molecules deep down in your teeth and whitening your smile.

2. Take-home whitening kit

Take-home whitening kits are used at home. The home whitening kit can be used on its own or in combination with in-office whitening, to maintain or improve whitening results. This usually involves taking impressions of your upper and lower teeth to fabricate custom bleaching trays. At home, you will fill each tray with a whitening gel (usually carbamide peroxide) your dentist provides. You will wear the trays for several hours every day, according to your dentist’s advice. Carbamide peroxide gel will break down into hydrogen peroxide which whitens the teeth.

3. Over-the-counter (OTC)

Over-the-counter (OTC) whitening products include gels, rinses, chewing gums, toothpastes, paint-on films and strips, which are readily available at pharmacies and your local supermarket. The problem with these products is that they do not offer any protection to the gums during bleaching and therefore causes more discomfort.

4. Non-dental options

The latest teeth whitening trend is the availability of whitening treatments or kits in non-dental retail settings, such as mall kiosks, salons, spas and, more recently, aboard passenger cruise ships. Non-dental whitening venues have come under scrutiny because the involved personnel are not educated in the use of disease screening or diagnostic tests (such as radiographs), and are not licensed or qualified to provide dental examinations. Additionally, their level of education and training in infection control is unknown (infectious diseases such as COVID-19 can spread via contact with saliva).

Comparison of different teeth whitening techniques2

*HP – hydrogen peroxide, *CP – carbamide peroxide

So, what’s the best option among the 4 choices of teeth whitening?

The safest and most effective teeth whitening methods are still in-office and take-home whitening. Both work equally well. However, in-office whitening produces the fastest results.

Here at Tan Dental Surgery, we offer both options for teeth whitening:

Most patients would opt for a combination treatment, whereby after a session of in-office teeth whitening, they will get a take-home whitening kit to whiten the teeth further or for maintenance.

Is it safe to buy whitening products online? They are so cheap!

The most effective whitening agent is still hydrogen peroxide. However, only dentists can prescribe hydrogen peroxide-based products for teeth whitening.

Most of the teeth whitening products sold online do not contain hydrogen peroxide. For products which contain hydrogen peroxide, the concentration and safety as well as effectiveness of the products are unknown.

So, the bottom line is that it is best to avoid online teeth whitening products. They might cause more harm than good. We are very excited to help brighten your smile. Don’t hesitate to contact us for a teeth whitening session.

TEETH WHITENING

Teeth whitening is now one of the most commonly requested cosmetic dental procedures. If you wish to have a quick smile makeover, check out our teeth whitening services below.

In-Office Teeth Whitening

In-office teeth whitening means professional teeth whitening procedure carried out by the dentist in the clinic. Here at Tan Dental Surgery, we use Opalescence™ Boost™ (made in USA) which does not require the use of light.

Studies have shown that light increases the risk of tooth sensitivity during in-office teeth whitening and the light may not improve the whitening effect1.

The procedure is quick and only takes about 1 hour to complete.

Take-Home Whitening Kit

Take-home whitening means professionally supervised teeth whitening using customised whitening tray. This can be done in the comfort of your own home.

The main advantage of take-home whitening versus in-office teeth whitening is that tooth sensitivity is reduced with the take-home whitening kit. This is because a lower concentration whitening gel is used for take-home whitening (using Opalescence™ PF 10%). It is also more convenient as teeth whitening can be done at home.

The main disadvantages are that a longer treatment time (a few weeks) is required and the trays would need to be worn overnight.

Teeth Whitening FAQs

Teaming up with your dentist is the best way to get the whitening results you want. Your dentist knows your oral health and can make recommendations that will allow you to get the best results in a time frame that works for you. Your dentist can also help you understand how the whitening process works, monitor your progress, and treat any sensitivity issues that may arise.

Everyone responds differently to whitening treatments and everyone will whiten at different rates. Some stains are easier to treat than others. Teeth that are yellow or brown are easier to whiten than teeth that are gray/blue. Younger patients typically whiten more quickly than older patients, but every patient is different.

When whitening, keep in mind that your smile looks most natural when the colour of your teeth matches the whites of your eyes. Some people want a Hollywood white smile, but that is not a natural colour for teeth and few people can actually reach that colour of white. Consider consulting with your dentist to help determine the perfect shade of white for you.

Teeth whitening is a safe, comfortable way to get a bright, white smile. Results and treatment time may vary depending on the level of staining and whiteness desired. Crowns, bridges, fillings, and veneers will not whiten.
Teeth whitening results are very stable and typically last about 9 months to 2 years, leaving you with a stunning smile long after treatment is over. However, there are a few factors that can make teeth lose their luster. Things like genetics, diet (e.g. coffee and tea), age, some medications (e.g. tetracycline), and certain habits (e.g. smoking) may affect the length of your whitening results. Fortunately, touch-up treatments are quick and easy, helping you get that bright, white smile back.

Tooth sensitivity is a relatively common side effect of teeth whitening. If sensitivity occurs, it is often temporary and will go away once you have completed the whitening process. Desensitising products are available to reduce and treat sensitivity.

Many professionally applied whitening treatments use a light or a laser during the whitening process. You have probably seen commercials for these kinds of teeth whiteners. Or maybe you've even seen kiosks in the mall where they'll use a light to whiten your teeth. Are these lights and lasers really effective, though? The answer is no. Current research shows that hydrogen peroxide alone is effective in whitening teeth, and that light activation adds no additional benefit.

Pregnant women, those with gum disease, worn enamel, cavities, and exposed roots should not whiten their teeth.

People whiten their teeth for many reasons. You can bring back some of that youthful appearance with a whiter, brighter smile. Do you have a wedding or important day coming up? A whiter smile can help brighten up special occasions. Some people whiten their teeth before a job interview to get that extra boost of confidence that comes with making a great first impression.

According to a recent survey by the American Academy of Cosmetic Dentistry, “close to one in two (48%) people believe that a smile is the most memorable feature after first meeting someone—more so than the first thing a person says (25%).” That same survey also found that “more than a third of respondents view people with a flawed smile to be less attractive (37%) and less confident (25%) than those with perfect teeth.” Smiles make a lasting impression and a bright, white, beautiful smile won’t be forgotten. People seem to agree—nothing beats a beautiful smile!
