Teeth whitening at the dentist

If you’re looking to whiten and brighten your smile, then you should consider visiting your neighborhood dentist for a professional teeth whitening. Dentists use a very high concentration peroxide along with other accelerants to give you the best whitening results. You can remove 3 to 5 shades of yellowness from your teeth in as little as 45 minutes. Plus, bleaching your teeth at the dentist is now more affordable than you can imagine. Most dentists run promotions and special deals on teeth whitening services so you can achieve amazing results at a fair price.

How does professional teeth whitening work?


Almost all teeth whitening products work the same way. They apply a high concentration of bleaching gel, either carbamide peroxide or hydrogen peroxide, to your teeth surfaces. Bleaching gel breaks down and releases peroxide which penetrates deep into your teeth surfaces. The peroxide breaks down internal teeth stains and removes the yellowness from your teeth, resulting in a whiter and brighter smile.

What are the steps in professional teeth whitening?

Most whitening sessions are completed during a single session. This usually lasts between 45 minutes to an hour. Here are the steps involved in professional teeth whitening:



Professional teeth whitening always starts off with a thorough examination. Your dentist needs to make sure that there are no major obstacles to bleaching your smile. There may be fillings or crowns on your front teeth that could cause a color mismatch. You may have exposed roots that could cause extreme sensitivity. These issues need to be addressed prior to bleaching your teeth. Your dentist also needs to make sure that your teeth are healthy and clean. Teeth covered with plaque and tartar don’t respond well to bleaching, so you may require a cleaning beforehand.


Once you’ve been cleared by your dentist, it’s time to start the bleaching process. Your dentist will measure your pre-whitening teeth color as a reference point. Sometimes they even take photos so you can compare your before and after results or to post to their website. The whitening treatment itself is typically done by a staff member under the supervision of your dentist. The first step is to isolate your teeth. This is done by placing a barrier where your teeth and gums meet. The bleaching gel that your dentist uses is very strong. Therefore, your gums need to be isolated so that the gel does not contaminate and caused damage to your gums. Put your headphones in, wear your glasses, and you’re now ready to start whitening your teeth!

Bleaching process

To start the whitening process, your dentist applies bleaching gel evenly to all teeth surfaces planned for whitening. This typically includes the outer surfaces of your front 6 to 10 teeth. Your molar teeth, which are located in the back, are usually not included in whitening treatment. Changing the color of your back teeth won’t affect your smile, plus it’s very difficult to apply the whitening gel onto these teeth. Now all you have to do is sit back, relax, and let the bleaching gel do its thing.

Benefits of whitening your teeth at the dentist

If you’re looking for the best results, you should whiten your teeth at your local dentist. There are many benefits to having your teeth whitened professionally by your neighborhood dentist, such as:

Strong bleaching gel for maximum results


Your dentist uses a much stronger bleaching gel than you’re allowed to use at home. At-home whitening products use a concentration of maximum 16% carbamide peroxide (or its equivalent hydrogen peroxide) whereas your dentist can use a concentration as high as 40% carbamide peroxide. The reason high-concentration bleaching gel is only available at the dentist is due to its high risks. High-concentration peroxide can cause extreme tooth sensitivity or gum inflammation. Occasionally, these side-effects are permanent and never improve over time. This is the reason why professional whitening gels are only available at your dentist and they’re not for at-home use.

Immediate results


Dentists use a high concentration peroxide gel to give you whiter teeth in just one session. Most teeth whitening systems also use a light source to improve the outcome. The light source, which is either an LEDhalogen or plasmaarc, breaks down the bleaching gel into its active ingredients to speed up the process for even better end-results.

Treatment in a controlled environment

Your dentist monitors your treatment to make sure you don’t end up with any problems. They protect your gums from getting damaged, help you address tooth sensitivity issues, and make sure that you’re 100% satisfied with the final outcome. At the end of the day, you get better results in less time, while having someone accountable for your treatment.

How much does professional teeth whitening cost?


Almost all general dentists offer some type of teeth whitening treatment. Most offer them at great prices and run promotions to make teeth whitening more affordable. On average, dentists charge a few hundred dollars for in-office teeth whitening treatment. There are different brands of teeth whitening and they all have different costs. The more popular teeth whitening brands, such as Zoom!®, Boost® and KöR®, are more expensive but they also give you better results.

Teeth whitening


There’s no question that having whiter teeth can improve your smile and appearance. Of course, maintaining pearly white teeth isn’t all that easy. Our teeth have a tendency to turn yellow over time. There are two main reasons why your teeth darken as time goes by:
(1) Your teeth develop deep stains which makes them appear yellower
(2) Your teeth lose their outer protective layer, known as enamel, which exposes the darker underlying layer and makes them appear yellow

Let’s look at a few common reasons why teeth change color and turn yellow:

Plaque & tartar

Tour teeth may simply look darker because they buildup too much plaque and stains. A simple dental cleaning removes these buildups and instantaneously gives you a whiter and brighter smile.

Tobacco Products

Nicotine, cigarette tar, and other tobacco products stain teeth and turn them yellow. This explains why most long-term smokers have darker and yellower teeth.

Certain foods & drinks

There are many food additives that stain your teeth. For instance, regularly drinking coffee or tea stains and darkens your teeth. Red wine, colas, fruit juices, berries, and most spices also contain additives that stain teeth and they cause your teeth to turn yellow with repeated consumption.

Exposure to acids

It’s no surprise that acid destroys your tooth enamel. Losing your enamel layer exposes the underlying tooth structure which results in permanently yellower teeth. So what causes acid damage to teeth? Carbonated sodas and juices, especially lemon juice, contain acids that damage your enamel. If you can’t kick your soda habit, then be sure to brush your teeth frequently. Drinking plenty of water also helps wash away the acid buildup from your teeth surfaces and protects against acid damage. Acids are also found in your stomach fluids, which are very corrosive and wears out tooth enamel rapidly. Frequent regurgitation, as evidenced in bulimics or those suffering from acid reflux, destroys your protective enamel layer and turns teeth yellow. Again, be sure to brush your teeth very thoroughly so that your teeth are not exposed to these acids for prolonged time periods.


As we get older we lose some of our protective tooth enamel layer. This makes your teeth appear yellower as if they have lost their youthful appearance.

Teeth Grinding

Grinding not only damages your teeth, but it also causes them to change color and turn darker. Heavy grinders wear away their tooth enamel over time, which causes teeth to appear yellower and darker.

How do I reverse yellow teeth?


You need to figure out why your teeth have turned yellow before worrying about whitening your teeth. If your yellow teeth are the result of internal stains, then it’s easy to reverse this effect with a professional tooth whitening treatment. However, if your teeth are yellower due to damage or loss of your enamel layer, then they are not likely to respond well to teeth whitening treatments. Let’s explore which cases are good candidates for teeth whitening treatment and which ones tend not to respond as well:

Excessive dental work in your mouth

Teeth whitening products change the color of your teeth by breaking down internal stains. However, they do not alter the color of your dental restorations, such as dental fillings, bondings, or crowns. If you have lots of existing dental work in your mouth, especially if they are located in the front, you should always consult with your dentist prior to starting a tooth whitening regimen. Otherwise, you could end up with an unsightly mismatch between your natural teeth and existing dental restorations!

Loss of your tooth enamel layer

Teeth whitening treatments aren’t effective if your teeth have turned yellow due to the loss of the protective enamel layer. This usually happens due to prolonged exposures to acidic products, teeth grinding, or simply a result of aging. These cases are not suitable for teeth whitening treatment, instead, they are better candidates for cosmetic dentistry procedures such as dental bonding and porcelain veneers.

Teeth covered with plaque and stains

There’s a chance your teeth look yellow because they are covered with plaque and stains. A professional dental cleaning can remove these stains from your teeth to significantly whiten your smile. Be sure to improve your brushing and flossing habits to maintain your new smile over time.

Am I a good candidate for professional teeth whitening?

If your teeth have turned yellow due to smoking, coffee, tea, red wine, etc. then you’re a great candidate for professional teeth whitening. The bleaching gel penetrates your teeth, breaks down internal stains, and significantly whitens and brightens your smile. Yellow teeth which results from grinding, acid damage, or aging is not a good candidate for professional teeth whitening.

Benefits of custom whitening trays

There are countless ways to whiten your teeth nowadays. Of course, the most effective whitening treatments are always delivered by your dentist. Dentists offer two types of teeth whitening methods, which are:

  • In-office professional whitening
  • At-home custom whitening trays

In-office teeth whitening is a professional whitening performed entirely at your dentist’s office. Your dentist will use a high concentration bleaching gel to whiten your teeth, typically during a one-hour session. Custom whitening trays is another way your dentist can help you brighten your smile. Your dentist designs your custom trays from moldings of your teeth. Use your custom trays to deliver high-concentration bleaching gel to brighten your smile. Let’s take a closer look at how custom whitening trays brighten your pearly whites:

Making your custom whitening trays


Custom whitening trays are specifically designed to fit your teeth. This explains why whitening trays are more effective at whitening your teeth as compared to over-the-counter alternatives. Dentists make these trays using impressions of your teeth. The lab blocks out space to accommodate bleaching gel onto teeth surfaces planned for bleaching. Custom bleaching trays fit comfortably in your mouth and they deliver the right amount of bleaching gel to teeth surfaces.

Bleaching gel

All teeth whitening treatments use some type of bleaching gel. The bleaching gel helps break down your teeth stains and removes yellowness from teeth. Be sure to use a reliable bleaching gel to go along with your custom trays. Avoid using knock-off beaching gels simply because it contains a higher concentration of bleach. Unregulated whitening gels could damage your gum tissue or cause extreme tooth sensitivity. Be sure to purchase your bleaching gel refills from a reputable tooth whitening company. Here’s a list of some of the more reputable bleaching gel manufacturers who offer custom tray gel refills:

How to use your custom whitening trays?


Begin by carefully applying the bleaching gel into your trays. Apply the gel evenly onto the front-facing surfaces of your teeth. Avoid placing whitening gel on the inside portion or onto your back molar teeth. Ask your dentist for assistance if you’re confused about where the whitening gel goes. Once you’ve applied the gel, carefully insert the trays into your mouth. Wear your trays as per the bleach manufacturer’s instructions. You may have to wear them for as little as 30 minutes or you may require overnight wear.

Once done, slowly remove the custom trays from your mouth. Avoid swallowing the excess gel and rinse out thoroughly. Brush your teeth afterward, without toothpaste, and clean your custom trays thoroughly. Store your custom trays and bleaching gel in a safe area for future use. Be sure to avoid food items that stain teeth, such as tea, coffee, red wine, etc. for the next few days.

Important instructions on using custom whitening trays


Custom whitening trays offer an effective and safe way of brightening your smile. Here’s a list of things to watch out for when using your custom whitening trays for the first time:

Minimize saliva contamination

Insert your custom trays carefully to minimize saliva contamination. Mixing saliva with bleaching gel dilutes the gel makes it less effective. It’s a great idea to eat something prior to using your whitening trays to reduce your saliva flow and get better results.

Use your bleaching gel wisely

Apply the bleaching gel evenly to cover teeth surfaces you want to bleach. Applying the gel unevenly could cause white spots where the gel is more concentrated and creates spotty results. Avoid getting the bleaching gel onto your gum tissue. Carefully remove any excess gel that sneaks its way out. Avoid applying bleaching gel where it’s not necessary. This includes your back molar teeth and the inside surfaces of your front teeth. Only apply the bleaching gel to the front-facing surfaces of your front teeth, the areas you actually want to whiten!

Be patient

Custom whitening trays need time to work. Leave your trays in your mouth until they finish doing their job. You’re usually looking at anywhere from 30 minutes to overnight wear. You may even have to use your custom whitening trays for several days in a row to see noticeable results. The longer you leave your trays in your mouth, the more effective the results will be. Follow the gel manufacturer’s instructions, be patient, and ask your doctor for assistance if you’re unsure about how to use your custom trays.

Stop treatment if it hurts

It’s normal to feel a bit of sensitivity when bleaching your teeth. However, if you start to feel extreme sensitivity or actual pain, you must stop your whitening treatment right away. Remove your trays, rinse your mouth thoroughly, and brush your teeth carefully. Consider switching to a weaker concentration of bleaching gel. If you already have sensitive teeth to begin with, it’s a good idea to use anti-sensitivity toothpaste before starting treatment. Toothpastes designed to help with sensitivity, like Sensodyne®, can help build tooth resistance to ease your sensitivity during and after the whitening treatment.

Benefits of using custom whitening trays


So you know by now that whitening trays are among the most effective ways to brighten your smile. Here are some other benefits of using custom trays to brighten your grin:

  • Custom whitening trays uniformly administer whitening gel to your teeth surfaces for best results
  • You can use your custom trays from the convenience of your own home while watching TV, cooking, or even sleeping!
  • Custom whitening trays fit snugly onto your teeth surfaces which makes them super comfortable to wear
  • You can reuse whitening trays as many times as you’d like to continue maintaining your white smile over time

Despite what many people think, teeth whitening results are not permanent. As you consume tea, coffee, cigarettes, berries, wine, etc., your teeth slowly start to turn yellow again. Custom whitening trays have a slightly higher initial cost, however, you can reuse them as many times as you’d like. This means that you can maintain your whiter smile at a fraction of what other whitening treatment treatments cost. In the long-run, using whitening trays is more cost-effective than going to your dentist for a professional whitening, or continuously buying whitening strips.
