In-Office Teeth Whitening and 5 Steps To A Bright Smile

Do you think that teeth whitening improves your smile and appearance? Professional in-office teeth whitening is the most common cosmetic dental procedure these days. Unlike at-home treatments that contain low concentrations of bleaching agents, in-office teeth whitening is carried out under the supervision of professionals who are able to use a high amount of bleaching gel. The result of this procedure is obvious immediately.

What is In-Office Teeth whitening

In-Office Teeth Whitening, also known as professional or chairside teeth whitening, is a cosmetic dental procedure performed by a dentist or dental professional in a dental office. It is a popular method for achieving a brighter and whiter smile in a relatively short amount of time. Unlike at-home teeth whitening kits, in-office teeth whitening involves the use of stronger bleaching agents and specialized equipment to effectively remove stains and discoloration from the teeth.

Advantages of In-Office Teeth Whitening

  • Yields the fastest outcomes.
  • The safest method of bleaching.
  • Reduces the risk of gum and tooth sensitivity, which were drawbacks to in-office teeth whitening. Dental diseases are more controllable due to thicker peroxide gels and the use of desensitizers such as potassium nitrate and fluoride.

Disadvantages of In-Office Teeth Whitening

  • Relatively more pricey than over-the-counter bleaching kits. The prices for teeth whitening at BeDental are available on our page here.
  • Results vary depending on age, heredity and the original shade of teeth, etc.
  • In-office teeth whitening does not last permanently. Shortly after treatment is completed, the teeth start accumulating stains. As a result, many dentists advise using a lower-percentage bleach at home as a follow-up that may be applied to the teeth for extended lengths of time and kept on the teeth for longer periods of time.

Stains Removal before In-Office Teeth Whitening

  • Certain stains on teeth, usually inorganic, may not react well to in-office therapy. In fact, these teeth may be considerably darker after the surrounding teeth have been whitened.
  • Trauma, which results in the dentin darkening.
  • Tetracycline antibiotics ingested during tooth-formation. These drugs interact  with the crystalline structure of both the tooth’s enamel and underlying dentin.
  • Overexposure to fluoride, which can cause fluorosis—is the main cause of teeth discoloration.

Who is not a candidate?

In-office teeth whitening is not recommended for those with the following conditions:

  • Gum and tooth hypersensitivity. The dentist will suggest at-home teeth whitening with low-dose of carbamide peroxide in order to prevent some unexpected situations. 
  • Pervasive staining. In-office teeth whitening are sometimes unable to remove deep and resistant stains. In these cases, dentists recommend a monitored regimen of at-home teeth whitening or other options such as bonding, crowns, or veneers.
  • Become transparent with age. It’s quite common for the front teeth, which are actually thin.
  • Exposed to tetracycline. Prolonged and higher-dose exposure to antibiotics can potentially lead to more pronounced tooth staining. As a result, the outcome of in-office teeth whitening may not meet your expectations as effectively.
  • Gum recession. People with gum recession should prioritize treating the recession before considering teeth whitening, as whitening procedures are ineffective on enamel-less tooth roots.It also can worsen the sensitivity of receding gum when exposed to whitening solutions.

Preparation for In-Office Teeth Whitening

  • First, prophylactic cleaning will completely remove the plaque and debris that have accumulated on your teeth over time. 
  • A comprehensive exam will be carried out to look for potential problems such as tooth decay, fractures and gingivitis. If these circumstances exist, bleach may irritate you to varying degrees. Your dentist will most likely postpone the treatment until these issues are resolved. 
  • Photos may be taken of your teeth, and their color measured on a shade guide. This serves as a baseline for evaluating your advancement.

Opalescence Boost Procedure


If you desire a dazzling white smile in no time, the perfect solution is OPALESCENCE BOOST®. The state-of-the-art Ultradent OPALESCENCE BOOST® In-Office Whitening System employs advanced technology to significantly whiten your teeth in just over an hour. It is an excellent choice for those seeking immediate results. Even after the whitening treatment is complete, the process continues to enhance the whiteness of your teeth for 12-24 hours. Start the treatment on a Friday, and by Monday, you’ll be greeted with an entirely new smile!

An important benefit of teeth whitening is the viscosity of the bleaching gel, which has received praise for this property. Opalescence Boost does not compose a light activator, instead it depends on chemistry to produce its effects. Its hydrogen peroxide gel solution at 38 percent comprises a special, patented ingredient called PF, a combination of potassium nitrate (which lowers the risk of sensitivity) and fluoride (the enamel-strengthener which reduces the risk of cavities).

Advantages of Opalescence Boost

  • Impressive Results: While most professional whitening treatments achieve an eight-shade difference, Boost surpasses this average with an eight-shade change. This means it statistically provides superior results compared to many competing products.
  • Minimal Sensitivity: Boost contains fluoride and potassium nitrate, which strengthen the enamel and prevent peroxide from reaching the teeth’s tubules, reducing sensitivity.
  • Fast Treatments: The active whitening phase of the treatment can be completed in less than an hour. Including preparation and wrap-up, the entire process takes approximately an hour and twenty minutes.

Disadvantages of Opalescence Boost

  • Frequent Touch-Ups: While some professional treatments offer long-lasting results, Boost’s effects typically last for 6-12 months. Therefore, you will need to maintain your smile at home or schedule additional treatments once a year.
  • Gel Reapplications: During each treatment, the dentist needs to reapply Boost’s gel every twenty minutes. This may become inconvenient if you were planning to use your phone or stream content during the procedure.


Total chair time: One to two hours.

  • Step 1: Place a cheek retractor into your mouth to help keep the lips and cheeks away, and expose all the teeth that are visible when you smile.
  • Step 2: Rubber-dam liquid or hardening resin is applied for both upper and lower gum to keep them clean and protect against any irritation caused by the bleaching gel.

  • Step 3: Then, apply bleaching gel, including hydrogen peroxide, to the front 10-12 teeth and spread a 0.5–1.0 mm thick layer of gel to the labial surface of the teeth with a small brush. Leave it for about 20-30 minutes.
  • Step 4: The bleaching gel is suctioned or washed off, and repeat steps 3. Stop when reference results are reached.
  • The teeth are checked in between gel applications to see how thoroughly they have whitened and whether more bleaching is necessary. 
  • Step 5: After the last application, the dentist suctions, washes gel off and removes the cheek retractor. Teeth whitening can range from two to three colors to eight shades (out of a total of 16).
  • Part of the whitening effect is due to dehydration during the bleaching process, which makes the teeth look whiter than their true new color. After a few days, that hue will become apparent.

If additional whitening is desired and no significant sensitivity is noted, reschedule the patient in 3–5 days for repeat treatment.

Or your dentist can suggest a regimen of take-home bleaching trays, if a suitable degree of whitening hasn’t been obtained.

However the outcome really depends on your natural teeth and oral hygiene routine.

It’s necessary to consume certain meals and beverages in moderation in order to limit the accumulation of stains and keep them from returning. The first 24-48 hours following treatment are crucial for avoiding certain meals and beverages since this is when your teeth will continue to whiten. 

A good guideline to remember is that anything staining your white shirt will also do so on your teeth. The following common meals and beverages should be avoided:

  • Black tea and coffee
  • Red wine
  • Sauces (soys, curries, tomatoes, etc)
  • Dark berries or strong-colored fruits
  • Tobacco
  • Dark sodas

Additionally, some desensitizing products that contain stannous fluoride can cause stains and should be avoided.

Maintenance and Long-Term Results of In-Office Teeth Whitening

Maintenance and long-term results are crucial considerations when it comes to in-office teeth whitening. While the immediate results of the procedure can be impressive, it is important to follow proper oral hygiene practices and take certain precautions to maintain the whiteness of your teeth over time.

Here are some key factors to consider for maintaining and maximizing the long-term results of in-office teeth whitening:

  1. Oral hygiene: Maintain a consistent oral hygiene routine by brushing your teeth at least twice a day and flossing daily. This helps remove surface stains and prevents plaque buildup, which can contribute to tooth discoloration.
  2. Avoid staining substances: Limit your consumption of foods and beverages that are known to stain teeth, such as coffee, tea, red wine, and dark-colored sauces. If you do consume these substances, it’s best to rinse your mouth or brush your teeth soon afterward to minimize staining.
  3. Quit smoking: Smoking is a major contributor to tooth discoloration. Quitting smoking not only benefits your overall health but also helps preserve the whiteness of your teeth.
  4. Regular dental visits: Maintain regular visits to your dentist for professional cleanings and check-ups. This allows your dentist to monitor the condition of your teeth and provide additional treatments or touch-ups as needed.
  5. Touch-up treatments: Depending on individual factors, such as diet and lifestyle habits, touch-up treatments may be recommended to maintain the desired level of whiteness. These treatments can be done at intervals determined by your dentist.
  6. Customized care instructions: Follow any specific care instructions provided by your dentist. This may include using at-home whitening products or avoiding certain foods and beverages for a period after the procedure.

Remember that the longevity of teeth whitening results varies among individuals, and lifestyle factors play a significant role. By practicing good oral hygiene, making conscious choices to minimize staining substances, and following your dentist’s recommendations, you can extend the benefits of your in-office teeth whitening treatment and enjoy a brighter, more confident smile for the long term.

Sensitivity management 

After treatment, there may be some sensitivity, but this usually goes away within a few days. Gum white spots may spring up, but they will also disappear (within about 20-30 minutes). Apply some Vaseline® (petroleum jelly) on your gums before inserting the trays if you suffer irritation while using your at-home teeth whitening treatments.

For the first few days following treatment, be cautious while cleaning your teeth and carefully use a toothbrush with soft bristles to prevent soreness. Be cautious when flossing and using a seesaw motion to slide floss between the teeth.

Teeth whitening procedures shouldn’t hurt or create a lot of irritation, while they have been known to produce slight discomfort or increased sensitivity in people who already have sensitive teeth.
