What is in-office teeth whitening? Professional in-office teeth whitening is becoming the most popular cosmetic dentistry procedure. In contrast to at-home procedures that use modest concentrations of bleaching agents, in-office teeth whitening is done under the supervision of specialists who can use a large amount of bleaching gel. The outcome of this operation is instantly apparent.
Advantages of In-Office Teeth Whitening
- Produces the quickest results
- The safest method of bleaching.
- Reduces the possibility of gum and tooth discomfort, which are disadvantages of in-office teeth whitening. Thicker peroxide gels and the use of desensitizers such as potassium nitrate and fluoride have made dental disorders more manageable.

Disadvantages of In-Office Teeth Whitening
- More expensive than over-the-counter bleaching kits.
- The results vary based on age, genetics, and the initial hue of the teeth, among other factors.
- Teeth whitening done in-office does not last forever. The teeth begin to stain shortly after therapy is done. As a result, many dentists recommend using a lower-percentage bleach at home as a follow-up treatment that may be administered to the teeth for longer amounts of time and left on the teeth for longer periods of time.
Stains Removal to In-Office Teeth Whitening
- Certain tooth stains, mainly inorganic, may not respond well to in-office treatment. In fact, when the surrounding teeth have been whitened, these teeth may be significantly darker.
- Trauma, which causes the dentin to discolor.
- Antibiotics containing tetracycline were consumed during tooth development. These medications interact with the crystalline structure of both the enamel and the underlying dentin of the tooth.
- The major cause of tooth discolouration is excessive fluoride exposure, which can lead to fluorosis.

Exceptional Cases
In-office teeth whitening is not recommended for those with the following conditions:
- Hypersensitivity of the gums and teeth. In order to avoid any unwanted complications, the dentist will recommend at-home teeth whitening with a low dose of carbamide peroxide.
- Staining is all over the place. Deep and stubborn stains might be difficult to remove with in-office teeth whitening. In these circumstances, dentists may recommend a carefully controlled at-home teeth whitening routine or alternative choices such as bonding, crowns, or veneers.
- With age, they become translucent. It is very frequent for the front teeth, which are very thin.
Preparation for In-Office Teeth Whitening
- First, prophylactic cleaning will eliminate all plaque and debris that has developed on your teeth over time.
- A comprehensive examination will be conducted to search for problems such as tooth decay, fractures, and gingivitis. If these circumstances exist, bleach may irritate you to varying degrees. Your orthodontist will almost definitely postpone treatment until these issues are solved.
- Your teeth may be photographed and their color quantified using a shade guide. This provides a starting point for measuring your progress.
Opalescence Boost Procedure
The viscosity of the bleaching gel, which has gained an appreciation for this quality, is a significant advantage of teeth whitening. Opalescence Boost is not a light activator; rather, it relies on chemistry to achieve its effects. Its hydrogen peroxide gel solution contains a unique component called PF, which is a mix of potassium nitrate (which lessens the risk of sensitivity) and fluoride (the enamel-strengthener which reduces the risk of cavities).
Total 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 the 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 will become apparent.
If more whitening is needed and no noticeable sensitivity is shown, reschedule the patient for a second treatment in 3-5 days.
If an acceptable level of whitening has not been achieved, your dentist may recommend a regimen of take-home bleaching trays.

Avoid some food and drinks
Certain foods and beverages must be consumed in moderation in order to reduce the formation of stains and keep them from returning. Because your teeth will continue to whiten over the first 24-48 hours after treatment, it is essential to avoid certain foods and beverages during this time.
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 (soy, 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.
Sensitivity management
There may be some sensitivity after treatment, but this normally goes away within a few days. Gum white patches may emerge, but they will also fade (within about 20-30 minutes). If you experience irritation when using your at-home teeth whitening treatments, apply Vaseline® (petroleum jelly) to your gums before placing the trays.
To avoid pain in the first few days after treatment, be cautious while cleaning your teeth, and use a toothbrush with soft bristles. When flossing, use a seesaw motion to glide the floss between the teeth.
