Teeth whitening is a simple, non-invasive cosmetic dental treatment that can change the color of your natural tooth enamel and enhance the beauty of your smile.
Because having whiter teeth has now become the number one aesthetic concern of most patients, there are a number of ways to whiten teeth. You’ve probably seen tons of over-the-counter whitening products at your local drug store, from whitening toothpastes to rinses to whitening strips and other types of at-home treatments. However, the single most effective way to whiten teeth is with a professional teeth whitening session in your dentist’s office.


Reasons for tooth whitening:


  • Fluorosis (excessive fluoridation during tooth development)

  • Yellow teeth due to age or normal wear of outer tooth layer

  • Stained teeth due to medications (tetracycline, etc.)

  • Stains from coffee, tea, red wine, or smoking

What does tooth whitening involve?

The ZOOM (PHILIPS) One Hour Smile Whitening Process can be completed in as little as one hour. However, we highly recommend getting a dental cleaning before your teeth whitening. This will add some time to your appointment, but it will enable you to receive even more dramatic whitening results from the treatment.

The first step in the actual whitening process is to apply a protective material to your gums so that the whitening gel will not irritate them. Next, the whitening gel will be applied to your teeth. Then, we will position a special teeth whitening UV light over your teeth to activate the gel and speed the whitening process. This part of the treatment takes 20 to 30 minutes.

After your treatment, you will be given tips about how to keep your smile bright for as long as possible. You may wish to schedule recurring treatments to make sure your teeth are always white.



At SPINEL DENTAL, we offer the ZOOM (PHILIPS) One Hours Smile Whitening Process to patients wishing to brighten their teeth and take years off of their appearance. The process is safe and comfortable and the results will be long-lasting, provided you take good care of your teeth and avoid staining agents such as tobacco, coffee, tea, and red wine.

Since teeth whitening only works on natural tooth enamel, it is important to consider how the presence of any old fillings, crowns, etc. will affect the results of your whitening treatment. Replacement of any restorations will be done after bleaching so they will match the newly bleached teeth.

Teeth Whitening FAQ

Gneral Knowledge

How Long Does It Take?

This depends on the type of treatment you seek and the professional who carries it out. In most instances however, a single whitening treatment takes in the region of 45 to 60 minutes. There may also be additional time required for advice and consultations, both before and after treatment. In addition, you may need any number of sessions over a given period of time, in order to benefit from the best possible results. Your dentist will advise accordingly.

Will There Be Any Pain or Sensitivity?

Again…and as is the theme with the whole piece…it depends on both the quality of the treatment carried out and the specifics of the patient in question. For example, if you already have particularly sensitive teeth, it is possible that you will experience heightened sensitivity or discomfort during the treatment process. That said, some dentists use whitening products and treatment processes in general that are significantly gentler than others. In any case, this is a question you should bring up with your dentist, before agreeing to go ahead. If your teeth are already sensitive, this is something they need to know about.

How Long Does the Treatment Last?

Exactly how long you can expect the results to last will be determined primarily by your lifestyle. For the average person, quality results by way of a premium whitening treatment will take about a year to fade back to their original shade. This is why many people decide to have the whiteness of their teeth ‘topped-up’ after several months. Just as proactively preventing stains from setting in can prolong the whiteness of your teeth, lifestyle habits like smoking, drinking red wine and failing to look after your oral health in general can speed up the discolouration process.

Is Professional Teeth Whitening Harmful?

It’s of crucial importance to ensure that you only ever entrust a reliable, reputable and recommended specialist with the process. Handled correctly, there is no reason why professional teeth whitening should be in any way harmful. But at the same time, substandard service providers who use excessively harsh chemicals and outdated techniques could potentially do your teeth more harm than good. Always look into the general status and reputation of any dentist, before committing to any of their treatments.

How Far In Advance Of An Event Should I Whiten My Teeth?

Dentists are often approached by those who are getting married, going on holiday or planning to attend some kind of event where they need their teeth to look their best. In such cases, those concerned often ask how far in advance they should get their teeth whitened. As a rule of thumb, the answer is somewhere in the region of three weeks. While it doesn’t take particularly long to undergo a professional whitening treatment, it is nonetheless recommended to give it a few weeks prior to the event, just in case additional top-ups are needed.

Will the Treatment Whiten Crowns, Veneers Or False Teeth?

Unfortunately, this is just about the only limitation is far as most professional whitening treatments are available. The products used to whiten teeth are designed to be used with teeth and teeth alone. In turn meaning that anything within the mouth that isn’t a natural tooth is unlikely to respond to the treatment. That said, professional whitening treatments can effectively clean and restore the original colour of false teeth. Nevertheless, it will not be possible for the treatment to whiten false teeth or veneers further than their original colour.

Is It Necessary To Have My Teeth Polished and Scaled First?

Some dentists recommend undergoing an intensive process of polishing and scaling the teeth, prior to having them whitened. In reality however, this isn’t strictly necessary. If you haven’t had your teeth scaled and whitened for some time, it could be in your best interests to get it done for general health and hygiene reasons. In addition, ensuring your teeth are at least adequately cleaned and flossed prior to whitening is important. But if your dentist tells you that it is fundamentally necessary to have your teeth polished and scaled first, they’re technically bending the truth somewhat.

Can Anyone Not Get Their Teeth Whitened?

Last but not least, there are no known side effects or potential risks of any severity that accompany teeth whitening. As such, just as long as you consult with a reliable and reputable service provider, pretty much anyone represents a candidate for teeth whitening. Nevertheless, those with existing oral health issues, sensitive teeth and gums, recent dental surgery or other general health issues may not be suitable for treatment. In addition, the vast majority of dentists refuse to carry out treatments on anyone under the age of 18, while some also advise against professional teeth whitening while pregnant. In all instances, your dentist is the best person to ask regarding your own suitability.

How White Will My Teeth Get?

Just as is the case with every whitening product and kit on the market, results vary significantly from one person to the next. While some come out of their first whitening session with an extraordinarily white smile, others need considerably more treatments to achieve the same results. What’s more, there will always be cases where an individual’s teeth simply cannot be made quite as white as another patient’s. As a rule of thumb however, most professionals set out to improve whiteness by a minimum of five shades, though typically edge closer to eight shades.

Opalescence teeth whitening

How does Opalescence gels teeth whitening work?

Working from the inside out, the active ingredients in Opalescence gels penetrate your teeth to break down the discolored molecules deep down in your teeth, removing stains and whitening your smile. Our original, patented formula contains PF (potassium nitrate and fluoride) and is sticky and viscous, so it stays where it’s placed. This unique feature prevents the gel from migrating during treatment and helping keep the gel and custom tray in place so it can continue whitening your teeth for the duration of the treatment. Stains on teeth can be classified in one of two ways: extrinsic or intrinsic. Extrinsic stains appear on the surface of your teeth. Intrinsic stains live between the microcracks in your enamel and deep within your dentin (the layer of your tooth underneath your enamel). Whitening toothpastes and mouth rinses may be able to remove some of the extrinsic stains on your teeth. But only teeth whitening agents can remove the stubborn extrinsic stains and the unsightly intrinsic stains that cause your teeth to look discolored.
Opalescence gels contain an active whitening ingredient (either carbamide peroxide or hydrogen peroxide) that penetrates your enamel to get to discolored molecules. Oxygen molecules from the whitening agents react with the discolored molecules in your teeth, breaking the bonds that hold them together. The oxygen molecules spread, whitening the entire tooth. As a result, you are left with a brighter, whiter smile.

Is teeth whitening for everyone?

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. We recommend visiting your dentist for a prewhitening consult so that they can help you choose the professional option that best fits your needs.

How long do teeth whitening results last?

Teeth whitening results are very stable, 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, age, some medications (like tetracycline), and certain habits (like 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. There are many factors that can affect the shade change of your teeth after whitening, so it's important to have realistic expectations before and after whitening. Depending on factors like current shade and staining, it may take longer to get that bright, white smile. You should also know there are certain foods, habits (like smoking), and medications that can cause staining to occur after your teeth have been whitened. You'll want to avoid these as much as possible during whitening in order to maintain your white smile.
Once you've achieved the level of white you want, it is up to you to maintain your bright, white smile. Remember it takes just as long to stain your teeth again as it did in the first place, and good habits and oral hygiene are the best ways to keep your dazzling smile. You may want to use a whitening toothpaste like Opalescence Whitening Toothpastes in order to help maintain your white smile while also increasing your oral health. If you are concerned that your white smile is fading, ask your dentist about a touch-up treatment for a couple of nights once or twice a year to retain your desired shade.

Will teeth whitening cause tooth sensitivity?

Tooth sensitivity is a relatively common side effect of teeth whitening. If sensitivity occurs, it is often temporary and will go away once you've completed the whitening process.

How to manage Whitening Sensitivity?

For some people, teeth whitening can cause sensitivity. Most often, sensitivity is temporary and treatable, so it's important to talk to your dentist before, during, and after your whitening treatment so they can understand and treat your sensitivity issues on an individual basis.
Before you begin any whitening treatment, you should undergo a whitening consultation with your dentist to determine your level of sensitivity and staining. Once your dentist has established your sensitivity level—usually by a touch and air test—they'll be able to determine which whitening treatment will be most comfortable for you while treating the stains appropriately.

Prewhitening Sensitivity

  • If you have a history of sensitivity, your dentist may recommend you take the following steps to help prevent sensitivity during the whitening treatment:
  • Using a soft-bristle toothbrush, brush your teeth with Opalescence Sensitivity Relief Whitening Toothpaste for 2 weeks.
  • Remove any acidic beverages and foods from your diet.
  • Wear a prefilled tray or custom trays filled with UltraEZ (desensitizing gel product) for 30–60 minutes once a day or Opalescence Sensitivity Relief Whitening Toothpaste for 1–2 nights.
  • Continue to brush with Opalescence Sensitivity Relief Whitening Toothpaste, but brush 30 minutes before you insert your tray, and wait 30 minutes after whitening to brush again.
  • Begin whitening with a low-concentration Opalescence product, or whichever Opalescence product your dentist recommends.

During Whitening Sensitivity
Some people who do not have a history of sensitivity may develop some level of sensitivity during their whitening treatment. If you develop sensitivity during your whitening treatment, your dentist may suggest additional treatment options:
Option 1
  • Reduce concentration of whitening material if possible
  • Reduce wear time
  • Change from night wear to day wear
  • Skip a night or day of whitening
  • Stop whitening for an extended period of time
Option 2
  • Continue or start brushing with Opalescence Sensitivity Relief Whitening Toothpaste
  • Wear UltraEZ (potassium nitrate and fluoride product) prefilled trays for 30–60 minutes once a day or your custom tray filled with UltraEZ overnight in place of whitening material for 1–2 nights
  • Switch from one whitening gel to another
  • If none of these treatments work, your dentist may recommend the whitening process be discontinued.

What is tooth whitening?

Tooth whitening is the removal of stains and discolorations from the enamel and dentin. The outer layer of the tooth is enamel, and beneath the enamel is dentin. Enamel is thin and typically much lighter in color, while dentin is darker in color and makes up the bulk of the tooth. Enamel can be discolored over time simply from age, but also from outside sources like coffee, tea, tobacco, and other foods and beverages. Also, as we age, our enamel thins, causing more dentin to show through, making the overall appearance of the tooth look darker. Whitening your teeth removes these stains and discolorations, giving you a whiter, brighter smile.

Can you whiten non-vital teeth?

Yes! Opalescence® Endo is designed specifically to whiten non-vital teeth. Consider talking to your dentist to learn more about the process for whitening a non-vital tooth.

Can I whiten a crown or a filling?

No, only natural tooth structure can be whitened, any crowns or fillings that you have will not react to whitening products. If you have a crown or a filling that is easily visible, you may want to talk to your dentist about different options for improving your smile.

Is there anyone who should not whiten their teeth?

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

Why should I whiten my 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!

How long does it take to whiten?

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 color of your teeth matches the whites of your eyes. Some people want a Hollywood white smile, but that is not a natural color for teeth and few people can actually reach that color of white. Consider consulting with your dentist to help determine the perfect shade of white for you.
