Best professional teeth bleaching


Created with the needs of individuals with sensitive teeth in consideration, the Snow whitening kit provides remarkably bright smiles with only a few minutes of daily use, catering to even the most delicate teeth.

Star-studded whitening

Snow is effective in removing stains caused by smoking, coffee, soda, and wine. In just three days, you can witness remarkable enhancements. The Snow whitening kit contains hydrogen and carbamide peroxide as its active ingredients. The blue LED light is specifically engineered to enhance the activation of the ingredients, thereby promoting increased efficacy. In addition, the serum is supplemented with peppermint oil in order to enhance the palatability of its taste.

The Snow whitening kit includes:

You can get the Snow whitening kit if you're ready to whiten your teeth and take your smile to the next level.

Custom-made trays

If you're looking at take-home whitening kits, we recommend you check out Smile Brilliant. Their whitening kit is identical to the treatment you'd get from a dentist, but instead of visiting a dental office to get your teeth whitening trays, you take your own impressions at home and mail them to the lab.

However, we strongly recommend visiting your dentist first to examine your teeth and determine if they are suitable for any whitening treatment.

Smile Brilliant's 22% carbamide peroxide gel is strong enough to whiten teeth by up to eight shades in a single treatment course. When you purchase your kit, you can customize it according to how heavily stained your teeth are and whether you need extra desensitizing treatments.

What's more, the gel is sealed in foil bags, which prevents light from breaking the peroxide down into the water. Thus you have a gel that maintains its strength for longer!

This is the closest you'll get to in-office whitening without actually visiting a dentist as you apply the gel in custom-made trays. The best part is that it can be purchased for as little as $149, with affordable refills available.

Sporting Smiles

Sporting Smiles professional whitening gel

Sporting Smiles follows the same concept as Smile Brilliant in that you order an impression kit online, make your impressions at home, and send them back in so that you can get custom whitening trays.

The gel from Sporting Smiles has 35% carbamide peroxide, and it delivers a special foaming action that ensures it whitens every crack and crevice of your teeth.

The trays are strong and will last for years, so you don't need to order new ones every time you want to whiten your teeth. Plus, Sporting Smiles is one of the more affordable whitening treatments that use custom trays on the market at just $80. You can get your impression kit now to get started.

Smile Avenue

Smile Avenue whitening kit contains carbamide peroxide to effectively whiten your teeth and hydroxyapatite to safeguard the enamel and aids in the remineralization of teeth, ensuring optimal protection against tooth sensitivity.

The results of Smile Avenue teeth whitening kit can be seen within a 12-day period. You can have a brighter smile with safety, efficiency, and zero sensitivity. With their innovative brush applicator that requires a reduced amount of gel, your kit is designed to provide you with 24-30 whitening sessions, ensuring long-lasting results.

You can apply the product directly onto your teeth using the brush provided for a safer and more cost-effective experience, as it helps prevent any gel from leaking onto your gums. Using the Smile Avenue whitening kit involves a simple three-step process, as detailed in their user guide. It costs $149, and the kit includes the following:

  • 3 x Smile Avenue Gel Pen
  • 1 x Desensitizing Gel Pen
  • 1 x Smile Avenue LED Light with micro-USB plug
  • 3 connectors: USB, USB Type-C, Lightning (iPhone)
  • 1 x Smile Avenue shade guide
  • 1 x Smile Avenue Velvet Pouch
  • 1 x User manual with instructions

Best professional teeth whitening procedures — in-office

Laser teeth whitening

This teeth whitening service, also known as “laser bleaching” or “power whitening,” involves the application of a whitening gel that contains an activator (aka Chromophores) that absorbs the wavelength of that particular laser, enhancing the bleaching process. The activator and whitening agent are usually combined at application.

how much does professional teeth whitening cost
Laser is a type of in-office teeth whitening

Laser teeth whitening costs more than other methods. Some clinicians agree that this method is the closest you'll get to “instant” teeth whitening. However, there is limited evidence that light-activated methods are more effective than others in the short term. In fact, effectiveness is usually attributed to the concentration of the bleaching agent.

The first step of the laser teeth whitening process includes the placement of a lubricant on the lips to protect the external soft tissue. Then, the teeth are coated with a bleaching product — usually containing hydrogen peroxide for teeth whitening. A laser shone on the teeth during treatment makes this whitening technique quick and effective.

The whitening process is usually performed in quadrants to limit the heat to the teeth. The procedure is typically quick, with a full mouth taking approximately 20 -30 minutes. Each quadrant has approximately 30 secs of laser application.

Here is a video of how laser teeth whitening works:

The results of laser whitening should be clear after just one visit, but your dentist may recommend repeating the process to achieve the results you desire.

Is laser teeth whitening safe?

Laser teeth whitening is safe when performed in-office by a licensed professional. However, because it is so intensive, laser teeth whitening side effects may include sensitivity in your teeth. Current research is conflicting, with some studies saying that this method causes the least sensitivity.

Other studies show that sensitivity is associated with the bleaching agent rather than the method. Due to the quick process, some clinicians may not recommend this method for people who want teeth whitening for sensitive teeth.

Any sensitivity should subside quite quickly but can be uncomfortable for some patients and extremely painful for others. This method may, therefore, be best avoided by people who want teeth whitening for sensitive teeth.

There have been concerns about the effects on the pulp (nerve) of the tooth due to external heat from lasers or the whitening gel, which is why the light and laser use by the dentist is very quick.

Zoom teeth whitening (LED)

Another professional teeth whitening option is Zoom whitening. Using technology from Philips works in a similar way to laser whitening but instead uses LED lights to accelerate a whitening agent. In most cases, Zoom tooth whitening costs less than laser whitening.

Zoom is one of the best teeth whitening services

LED teeth whitening systems like Zoom are not as intense as laser treatment, so you might need more than one session to see the results you want, although Philips claims they can whiten teeth by up to eight shades in an hour.

LED whitening has largely replaced UV whitening since it's safer and proven to be more effective. It's UV light that causes sunburn and skin cancer, so using it in the mouth can damage gums, cheeks, and lips.

With Philips Zoom teeth whitening, you can choose between two whitening options—Zoom QuickPro and Zoom WhiteSpeed. Let's have a closer look at these options now.

Zoom QuickPro

Zoom QuickPro was designed so that patients could spend a minimal amount of time in the dentist's chair. It takes just 30 minutes of in-office time and is ideal for touching up the whiteness of your teeth or getting a jump start on the whitening process. According to the Philips website, you'll get 4 shades brighter in a single 30-minute session.

How does it work?

  • Your dentist preps your mouth and gums
  • They apply whitening varnish to each tooth
  • They then apply a protective sealant to protect from sensitivity
  • You are free to go! After 30 minutes, once you're back at home, brush off the dried varnish, and you'll have your results.

Zoom WhiteSpeed

Zoom WhiteSpeed offers the most results. It takes 45 minutes, and teeth can get up to 8 shades whiter. Should you choose these options:

  • Your dentist preps your mouth and applies whitening gel to your teeth
  • They shine a blue LED light on your teeth to speed up the whitening processes
  • This is repeated three times
  • Your dentist applies a protective gel after treatment

Zoom teeth whitening review

To give you a better idea of what this whitening treatment involves, here is a video review from a woman named Brooklyn who had Zoom whitening at the dentist. She explains the process in detail and shows each step as it happened, so it's interesting to watch if you're considering having this treatment.

Brooklyn made two visits to the dentist, the first to create molds of her teeth and the second for the actual whitening. The whitening consisted of three 15-minute sessions, all on the same day.

Straight after her whitening session, she was given mouth trays containing a sensitivity-reducing gel, which she wore for 30 minutes. This last step makes this a good option for those looking for teeth whitening for sensitive teeth.

Zoom teeth whitening near me

You can find Zoom teeth whitening at dentists all over the country. If you need help finding a dentist who offers Zoom in your area, call 866-383-0748 to get connected and make your appointment.

Enamel microabrasion

Enamel microabrasion is an in-office procedure used to remove stains from the surface of your enamel. It involves using a combination of abrasives and acid to remove a micro layer of the enamel. The layer that is removed is so small that there aren't any negative side effects except for temporary sensitivity.

You can find out more about this procedure in our full guide here.

How much does professional teeth whitening cost?

Professional teeth whitening at the dentist costs from $300 to $1,800, depending on the procedure. Zoom teeth whitening costs around $400 on average, and laser teeth whitening costs around $1,000.

How much does laser teeth whitening cost?

teeth whitening dentist cost
Dentists' teeth whitening costs vary greatly

Laser teeth whitening costs the most when it comes to teeth whitening professionally because of the technology used, but it offers the fastest and most noticeable results. You can expect to pay around $1,000 for laser teeth whitening.

At-home dental whitening costs less than teeth whitening costs at the dentist because you're spending relatively little time in the dentist's chair.

Note that the main benefit of laser and LED whitening over take-home trays is the speed at which they produce results. If you are happy with more gradual whitening, a take-home bleaching kit will still give good results over the duration of the treatment.

It's worth getting quotes from more than one dentist for the laser teeth whitening cost since professional dental teeth whitening costs vary from one clinic to another according to a number of factors.

Another way to save money on professional teeth whitening and laser teeth whitening costs is to get your treatment abroad. If you live near the Mexico border, you could save hundreds of dollars on dental whitening (and any other treatments) by visiting a dentist in Mexico.

Alternatively, you could get cheaper teeth whitening while on holiday in places like Costa Rica or Thailand. Read more about getting dental work abroad here.

Benefits of professional teeth whitening

Although the cost of teeth whitening at the dentist is higher than at-home alternatives, there are a number of safety benefits that the best in-office teeth whitening treatments offer:

teeth whitening dentist costs
A barrier protects the gums from the bleach
  • The dentist will check that you're a suitable candidate for safe teeth whitening. If you have inflamed gums or tooth decay, for example, whitening is not advisable.
  • The bleaching ingredient is stronger than a patient will find in any home whitening kit. It can be as high as 30-35% hydrogen peroxide. The higher the percentage, the lower the pH (can be as low as a pH of 4). This is why fluoride treatments are advised, along with routine care.
  • For in-office whitening, your gums will be protected with a seal or shield.
  • Mouth trays are custom-made to fit your teeth properly and ensure even gel coverage.
  • The dentist controls your treatment intensity and duration to produce the results you desire.

There is also a notable time advantage with in-office procedures. The American Dental Association (ADA) states that “while OTC products are less expensive than at-home or in-office approaches, there is a time trade-off in that OTC products may take significantly longer than do either of the other options for whitening.”

Ask a dentist: Why get in-office whitening treatment?

Most home whitening kits just do superficial work, cutting down on surface stains. It could take up to a month to see any results, and your teeth are going to get maybe three or four shades lighter. At-home trays that you can get at the dentist’s office are more effective, but you will still have to wait a week or two to get results.

With laser teeth whitening, the procedure doesn’t take much more than an hour, and you get long-lasting results. It uses light-activated bleaching, and just one appointment can get your teeth eight shades lighter. You aren’t going to get that kind of immediate result from a home whitening kit.

Dr. Alexei Aguil, Exquisite Dentistry

Note that although laws vary by state concerning who can legally carry out tooth whitening, the ADA recommends all bleaching is performed or supervised by a professional. 

“Dental professionals are responsible for managing patient care and are a key resource on oral health to the public at large. Consumers may pursue tooth bleaching without understanding the risks of treatment or the factors that may affect treatment success or failure. For optimal safety and to ensure proper diagnosis and treatment, examination by a dentist is necessary.” explains the ADA.

How do I find professional teeth whitening near me?

Not all dentists offer cosmetic tooth whitening, and those that do each have their own preferred methods and brands. First, decide which kind of whitening you would prefer. Then, search for a teeth whitening dentist near you using the internet or by asking around in your area.

Your first step will be to have a consultation with a teeth whitening professional who can assess your suitability for your chosen teeth whitening procedure. This gives you a chance to ask about the dentist's teeth whitening costs and any other questions you may have.

If you don't already have a dentist in mind, call 866-383-0748 to get connected to a dentist offering teeth whitening near you.

If you have dental caries or inflamed gums, you'll probably need treatment for this before getting your teeth whitened. The strong bleaching products that dentists use can easily lead to increased inflammation or sensitivity if used on patients with untreated dental problems.

If you have teeth sensitivity, the most commonly used ingredient for teeth sensitivity administered in the dental office (pre or post-treatment) is potassium nitrate or sodium fluoride.

Summary of dentist teeth whitening costs and options

In this table, you can see a summary of how much professional teeth whitening costs at the dentist using the different methods we've mentioned.

Approximate cost

Treatment takes...

Results appear...


Laser whitening

$400 - $1,800

1 hour, 1 or more sessions

Right away

Intense whitening procedures can cause greater sensitivity

Zoom whitening

$300 - $1,000

1 hour, 3-4 sessions

Right away but build up during treatment

Whitening trays can be used at home following this procedure to maintain results

Professional bleaching

$300 - $900

3-4 weeks with 2-3 dentist visits; 30 minutes - 8 hours for each home treatment

3-14 days

Begins with 2-3 dentist visits and is completed at home; 8-hour treatment can be done overnight

Remember, these professional teeth whitening costs include:

  • The expertise of a qualified professional
  • Specialized technology
  • High-quality, concentrated whitening ingredients
  • Assistance if you experience sensitivity or any other problems

Additional work, such as hygiene treatments and fillings, will incur extra charges. These high costs are why we recommend more affordable, and very effective, at-home professional teeth whitening options.


If you're considering whitening your teeth, you'll be joining a popular trend — in 2020, 37 million Americans used teeth whitening treatments, and dental bleaching is more than a $5.2 billion global industry (as of 2021).

If you want fast results, laser whitening and Zoom whitening can whiten teeth by several shades in just one hour. A bleaching kit supplied by your dentist is a more affordable way to achieve good results while still under the supervision of a dental professional.

All of these methods of professional teeth whitening at the dentist can be expensive. Those wanting a cheaper way to get whiter teeth can try a home whitening system instead. There are many brands of kits available, but we recommend choosing one like Smile Brilliant, which comes with lab-made mouth trays to fit securely around your teeth.

Other kits like Snow and Smile Avenue are also very popular for home whitening but use a different system without custom trays. But remember, not everyone is a good candidate, so check with your dentist first.

3 Ways To Finance Dental Work That Aren’t Insurance


How do dentists whiten teeth?

Dentists whiten teeth by applying a bleaching agent (often hydrogen peroxide) to remove stains on teeth and give teeth a whiter appearance. Common treatments include Zoom and laser teeth whitening.

Qualified dental staff are allowed to use higher concentrations of peroxide than you'll find in over-the-counter teeth whitening kits. This means professional whitening services can deliver better results.

How long does teeth whitening take?

Professional teeth whitening can take just an hour of treatment in the dentist's office. You may need several visits to the dentist to achieve the desired results. If you opt for a professional bleaching kit, you should start to see results after a few days of daily use, but treatment continues for around 10-14 days.

How long does professional teeth whitening last?

Professional teeth whitening can last for 2 to 3 years after the procedure. However, results will diminish sooner if you consume a lot of foods and drinks that cause teeth to stain. We have some information on how to avoid yellow teeth in a separate article. Results will also vary for each person based on:

  • The original shade of your teeth
  • The whitening method used
  • How well you care for your teeth after whitening
  • The kinds of food and drink you consume after whitening

Does professional teeth whitening work?

Yes, in most cases, professional, dentist-approved teeth whitening is an effective treatment. With professional treatments, your dentist can remove both intrinsic and extrinsic staining in most cases.

There are some cases, like if your teeth are severely discolored from taking certain antibiotics as a child, that may not be suited to professional whitening.

How much is professional teeth whitening?

Professional teeth whitening costs average between $300 to $1,800. These costs of teeth whitening, including laser whitening costs, depending on where you go and the exact procedure you choose. The average cost for Zoom teeth whitening is around $400, and laser teeth whitening costs around $1,000.
