Teeth whitening gel dentists use

Common ingredients of teeth whitening gel dentists use:

Carbamide Peroxide and Hydrogen Peroxide – One of the most commonly used ingredients in whitening gels is carbamide peroxide, a common whitening agent in many dental products. It is a source of hydrogen peroxide, which whitens teeth by reacting to existing stains by changing its chemical structure to eliminate pigmentation. hydrogen peroxide helps eliminate both superficial stains and deeper pigmentation on teeth.

Slow-acting and fast-acting whitening gels:

Your dentist can provide you with carbamide peroxide as a slow-acting whitener so you can use it at home. At your first consultation, your dentist will take an impression of your mouth and, at your next visit, you will receive a pair of whitening protectors and their corresponding whitening gel to apply at home. The fast-acting whitening gels that dentists use in the office have a higher concentration of hydrogen peroxide: about 30%. This makes the whitening process faster than when done at home, but can also cause more sensitivity.

Other ingredients: Many teeth whiteners contain added ingredients to help decrease tooth sensitivity. Two common ingredients in whitening gels are potassium nitrate and amorphous calcium phosphate, whose action to reduce sensitivity is proven. However, the sensitivity that may occur after teeth whitening usually occurs for a couple of days and subsides later.

What is teeth whitening gel?

A whitening gel is a gel that incorporates some type of teeth-whitening agent such as hydrogen peroxide or carbamide peroxide into its formula, although there are also peroxide-free whiteners.

Even if you’ve already whitened your teeth, some stains may reappear over time, especially if you like to drink coffee, red wine, or other highly pigmented foods or drinks.

But if you repeat your at-home whitening treatment sporadically, you have a greater chance of staying white for longer.

If you already have a whitening kit at home, getting replacements for it is easy. You can use refills of teeth whitening gel for the trays you already have in your kit.

What are the different concentrations of gels?

Commonly used concentrations are 16% CP, 22% CP, 35% CP, 44% CP, 6% HP, 16% HP, 22% HP, 35% HP, these are peroxide whitening gels. CP refers to carbamide peroxide, and HP refers to hydrogen peroxide gels.

The conversion relationship between CP and HP: The oxygen content of 1 unit of HP is equivalent to the oxygen content of 2,765 units of CP. For example, the oxygen content of 44% CP is equivalent to 16% HP.

From the perspective of the target market, different consumption habits in foreign countries use different concentrations. For example, the European Union has higher requirements for whitening gel.

The concentration of whitening glue determines the speed of the effect, high concentration, fast effect; The lower the concentration, the slower the effect. However, the high concentration will cause some irritation to the oral cavity. This irritation also varies from person to person. People have individual differences. Each person has a different sensitivity to their teeth and gums. It is best to use it with a gum protector.

How white can teeth be after using gels?

It can be guaranteed to improve tooth color, but the natural background color of each person’s teeth is different. Unless artificial dentures (such as porcelain or dental veneers) are made, real teeth can’t reach the so-called “white and flawless” level. No product in the world can turn yellowed teeth into pearls. From the actual effect, most people can whiten 3 to 9 shades of teeth.

Because the surface of the tooth is covered by a layer of enamel, it is transparent or translucent, and its deep part is dentin, which is pale yellow. Tooth color is related to the degree of enamel calcification. The higher the degree of calcification, the more transparent the enamel, and the true color of deep dentin makes the teeth light yellow; Otherwise, the teeth will look abnormally white or milky.

Therefore, light yellow teeth indicate that your enamel has a high degree of calcification, which is a sign of health. On the contrary, because poorly developed and calcified teeth are mostly white, and teeth with initial caries, calcareous plaques form due to demineralization.

How do you apply whitening gel to teeth?

Different styles of whitening gel have different application methods, such as spreading the gel on your teeth or applying it to trays:

Pre-gelled strips:

These are possibly the easiest to apply since you just have to dry your teeth and stick the upper strip to the upper teeth and the lower one to the lower teeth. You then remove them after the indicated time.

Refillable mouth trays: 

These are a little less straightforward as they require you to fill them with a quantity of whitening gel from a pod or syringe. When you place the tray in your mouth, enough gel should drip onto your teeth to whiten them. However, some may also get on your gums. If you want to know more about whitening with splints, check out this article.

Gel Pens:

These require you to paint your teeth with the gel, so you can ensure you get an even amount on your teeth and none on your gums.

Types of teeth whitening gels

Whitening gels can also come in different packaging. Some examples are:



*Whitening strips:

The different styles available can make a difference, some are easier to use and others are safer for your teeth. If you already have a whitening kit, you can use the refills with the mouthpiece, trays, and LED lights you already have.

Whitening gels that come in pen form are the least messy and safe for your gums as they are painted directly onto your teeth. The capsules and syringes are easy to use, as you just have to fill the whitening tray and place it for use.

Carbamide peroxide teeth whitening gel

Carbamide peroxide is a chemical compound commonly used in teeth-whitening gels. It works by breaking down into hydrogen peroxide and urea, which then oxidizes and removes stains from tooth enamel.

The most commonly used percentage of carbamide peroxide in teeth whitening gels is 6 to 35%. The higher the percentage of carbamide peroxide, the stronger the whitening effect. However, it is important to note that higher concentrations of carbamide peroxide may also increase the likelihood of tooth sensitivity and gum irritation.

It is recommended to start with a lower concentration of carbamide peroxide and gradually increase if necessary under the supervision of a dental professional. The length and frequency of use additionally rely on the proportion of carbamide peroxide used.

A higher concentration should be used for a shorter period and less frequently to minimize sensitivity and damage to tooth enamel.

Hydrogen peroxide gels

Gel forms of whitening agents such as hydrogen peroxide are frequently used to whiten teeth. The main component of these products is hydrogen peroxide, which interacts with the natural colors of your teeth to break them down and remove them.

The amount of hydrogen peroxide most commonly used in these solutions is 35%. Although most people find this dosage to be safe and efficient, it should only be used under the supervision of a dentist or other dental professional.

Lower amounts of hydrogen peroxide (such as 6% or 8%) can also be used to whiten teeth, but they may not be as effective at removing stubborn stains. High amounts of hydrogen peroxide (such as 16% or more) are generally not recommended due to the risk of damage to teeth and gums when used incorrectly.

PAP teeth whitening gel

PAP whitening gels are a type of teeth whitening product that contains phthalimido peroxy caproic acid (PAP) as an active ingredient. PAP is a relatively new whitening agent that is effective in removing dental stains and discolorations.

Common percentages of PAP in whitening gels can range from 2% to 18%, with 12% being a commonly used concentration. It is important to follow the instructions on the product label or those provided by a dental professional when using PAP whitening gels, as overuse or incorrect application can cause sensitivity or damage to your teeth and gums.

By penetrating the enamel and whitening stains, oxygen molecules leave it looking brighter and clearer.

These gels can be brushed on or placed on a plate specially designed to fit your teeth. The tray technique is more efficient because it allows for more uniform dispersion of the gel and better adhesion of the gel to the teeth. For a period of one to two weeks, it is recommended that people use the gel for 30 to an hour every day. Depending on the severity of the stain, the course of therapy may differ, but it is essential to remember that abuse can cause teeth to become sensitive and irritated.

Teeth Whitening Gels 35% HP

While HP 35% Teeth Whitening Gel can be very effective, it is important to note that this concentration level is strong and should only be used under the supervision of a dental professional. Improper use can cause tooth sensitivity, gum irritation, and even chemical burns. A dental professional can help ensure that treatment is safe and appropriate for your individual needs.

One of the main benefits of 35% HP teeth whitening gel is its high level of effectiveness. This concentration can produce dramatic results in a short period and can remove even the toughest stains that may not respond to other types of whitening treatments.

However, it is important to note that not all types of discoloration can be treated with teeth whitening and that results may vary depending on factors such as the person’s age, diet, and oral hygiene habits.

16% CP Teeth Whitening Gels

Users typically apply the gel to their teeth using a custom-made tray that is worn for a few hours each day, with results typically visible within a week or two of regular use.

Another advantage of this gel is its relatively low sensitivity profile compared to other teeth-whitening agents, such as hydrogen peroxide. While some users may experience minor sensitivity during treatment, it is generally less intense and shorter-lasting than the discomfort associated with other whitening products.

However, it should be noted that using 16% CP teeth whitening gel for prolonged or frequent periods may cause discomfort or sensitivity in some people. It is important to follow the instructions provided by the manufacturer or dentist and consult a dental professional if any problems arise.

35% CP Teeth Whitening Gels

Efficacy is another advantage of 35% CP teeth whitening cream. It offers more dramatic effects than over-the-counter whitening products because it is a professional-grade option.

How should teeth whitening be done to be safe and effective?

Professional dental whitening in a clinic, to be safe and effective, must guarantee that it does not harm your teeth or cause excessive tooth sensitivity. Here are some key features that good in-clinic teeth whitening should have:

*Professional supervision: A trained dentist or dental hygienist must perform the procedure and supervise the entire process. This ensures that it is applied correctly and problems are avoided.

*Pre-evaluation: Before whitening, a complete dental evaluation should be performed to ensure that your teeth are in good health and there are no problems such as cavities or gum disease that need pre-treatment.

*Using safe products: Quality teeth whitening products that comply with relevant standards and regulations should be used. Generally, hydrogen peroxide or carbamide peroxide gels are used in safe concentrations.

*Gum protection: To avoid irritation of the gums, they should be adequately protected with barriers or rubber protectors before applying the whitening gel.

*Sensitivity management: Dentists can apply sensitivity-reducing products before, during, and after the procedure if you are prone to tooth sensitivity.

*Controlled time: The exposure time to the whitening gel must be carefully monitored to avoid excessive whitening that could damage tooth enamel.

*Professional equipment: Dental clinics use special lamps or lights to activate the whitening gel, which speeds up the process and improves results.

*Gradual results: Whitening results should be gradual and natural, avoiding excessively white teeth that may appear artificial.

*Follow-up and recommendations: After the procedure, the dentist should provide instructions on how to care for your teeth at home and avoid foods and drinks that could stain them again.

*Dental history: Your dental history and any pre-existing conditions should be taken into account when planning whitening, as some people may not be suitable candidates due to certain dental conditions.

Always consult your dentist before undergoing teeth whitening to make sure it is right for you and done safely. Avoid at all times performing home teeth whitening that could compromise the health of your teeth and gums and go to a specialized center.

Why do teeth become stained?

Age: There is a direct correlation between teeth color and age. Over the years, teeth darken as a result of wear, decay, and stain accumulation. Teenagers experience immediate and noticeable results with whitening. After the age of twenty, when teeth begin to take on a more yellow tinge, whitening may require a little more effort. After age forty, yellow gives way to brown, and more maintenance is probably needed. After age fifty, your teeth have absorbed a lot of stubborn stains that can be difficult (but not impossible) to remove.

The initial color: We are all equipped with a tooth color from birth that varies between brownish-yellow and greenish-gray and that intensifies over time. Brownish-yellow generally responds better to bleaching than greenish-gray.

Translucency and thinness:

These are also genetic characteristics that become more pronounced with age. Although all teeth are somewhat translucent, those that are thicker and more opaque have an advantage: they look lighter, have more shine, and respond better to whitening. Teeth that are thinner and more transparent, especially the front teeth, have less of the pigment needed for whitening. According to cosmetic dentists, transparency is the only thing that cannot be corrected with any form of teeth whitening.

Eating habits:

Over the years, regular consumption of red wine, coffee, tea, cola, carrots, oranges, and other brightly colored foods and drinks causes noticeable stains on the teeth. Additionally, acidic foods such as citrus fruits and vinegar contribute to enamel erosion. As a result, the surface becomes more transparent and the yellow dentin is seen more.

Smoking: Nicotine leaves brown residues that slowly soak into the tooth structure and cause intrinsic discoloration.


The use of tetracycline during tooth formation produces dark gray or brown stains that are very difficult to remove. Excessive fluoride consumption causes fluorosis (discoloration characterized by the appearance of faint white marks on tooth enamel) and white-speckled areas.

Grinding: Teeth grinding (crunching, bruxism, etc.), often caused by stress, can increase microcracks in the teeth and cause the incisal edges to darken.

Trauma: Falls and other injuries can cause considerable cracks in the teeth, which accumulate a large amount of stains and debris.

How long will it take to take effect when using teeth whitening gels?

Generally, exogenous discoloration can be seen in 2-3 days, and a 14-day treatment course can be significantly improved. In the case of endogenously stained or mild tetracycline teeth, it takes more than 3 weeks to see obvious changes.

Tips for use at home

Before starting treatment with a whitening gel, consult your dentist. They can make you a personalized protector with the contour of your mouth and explain how to use the gel correctly. For example, you must always brush your teeth before applying the treatment gel. Depending on the product, you may need to wear the protector for a few hours of the day or you may need to wear it at night.

Your dentist may also recommend using the protector for approximately two weeks to obtain the desired results. Be careful not to swallow the gel. Carefully remove all debris from your teeth and gums with a cloth, a clean finger, or a soft toothbrush, then rinse your mouth thoroughly.

Side effects of teeth whitening gel

Some people are concerned about how safe teeth whitening products are to use. According to a popular article from the National University of the Northeast, peroxide-based whitening agents, like those used in many of these products, can cause gum irritation. This can happen if the gel is used with an ill-fitting protector or if it is applied incorrectly.

Tooth sensitivity may also occur, although both irritation and sensitivity usually disappear after treatment. The best way to avoid and prevent these side effects is to perform whitening under the supervision of your dentist.

Whitening gels are a good way to make your smile look more radiant, so consult your dentist to find out if you are a good candidate for teeth whitening. To keep your smile radiant longer, floss every day and brush your teeth twice a day with whitening toothpaste. Don’t forget to go to your appointments with the dentist: the polishing action of professional cleaning treatments is essential to combat superficial stains. With a little effort, you can say goodbye to yellow teeth and hello to your new, revitalized smile.
