How to choose your dental bleaching kit

#1 - Type of product

This is the main criterion for differentiating between whitening treatments.

Each type has its advantages and disadvantages.

For example, whitening toothpastes are the most accessible and easiest to find, but their effectiveness is generally dependent on a longer or shorter treatment time and their composition. They are free of hydrogen peroxide but often contain fluoride, so they are healthier and more harmless.

More popular with women, whitening pens are very practical and easy to use, despite their higher price.

After the chewing gums that clean have appeared the chewing gums that whiten. These are less expensive but their effectiveness is relative.

Then come the whitening kits that use hydrogen peroxide to whiten your teeth. They are more expensive but their effectiveness is also relative.

Tray kits are also very common on the market, but you have to make sure that the product is suitable for you, otherwise it will be a waste of time.

Finally, smile bars are also a solution proposed in institutes. The product offered there is not sufficiently controlled, if it is too concentrated, it can cause gum burns or necrosis of the teeth.

#2 - The concentration level of hydrogen peroxide

Many tooth whitening treatment products are made with hydrogen peroxide. However, it's best to check the level. Dental offices prescribe products with a 10% concentration of hydrogen peroxide, compared to only 0.01% on many brands of toothpaste.

It should be noted that the use of hydrogen peroxide-based products implies regular brushing of the teeth according to the rules of the art: an average of 3 minutes. It should also be used with caution because this product can damage the dentin of the teeth and reduce their strength.

#3 - Make sure you choose the right accessory

There

are many kits with trays on the market. Some of them are different from those dispensed by dentists. The results are then likely to be absent, because the product is not static.

It is diluted in the mouth, which does not allow good contact with the teeth. It is therefore better to opt for the kits with the adapted mouthpiece. The use of a thermos mouthpiece that adjusts to your teeth is also recommended.

#4 - Acidity level

The

penetration of the principle, and therefore the effectiveness of a teeth whitening treatment product, depends on its acidity level. Some toothpens, although very popular with women, have too low a level, which does not bode well.

#5 - The dosage

The

concept of express whitening often involves overdosing. Thus, some teeth whitening treatment products represent a real danger for the mouth. Too concentrated, they can cause dental problems or gum burn. If they are less concentrated, they are of no use.

Those who are used to these various products should be careful. It is better to find out about the active ingredients contained in the products, as well as their dosage.

#6 - The right ingredients

Grandmother's recipes are simple and effective. Nevertheless, the choice of ingredients is essential. Thus, it is better to avoid the trick of rubbing lemon on the teeth. This practice weakens the enamel and makes the teeth too sensitive.

On the other hand, chewing apples, carrots or celery pays off. These foods increase the production of saliva tenfold, which prevents deposits on the teeth.

#7 - The natural colour of the teeth

The

natural color of the teeth serves as a basis for choosing teeth whitening treatment products. If it is rather off-white, sodium bicarbonate or baking soda is best. For long-lasting results, this treatment should be combined with regular brushing of the teeth. The use of an electric toothbrush is also highly recommended. On the other hand, colored foods such as tea, coffee, or even red wine should be avoided.

#8 - Duration of treatment

The

effectiveness of a tooth whitening treatment product depends on the length of the treatment. On average, if the first results are still not seen after two months, it is better to turn to another product. The best solution remains a consultation with the dentist to find out which product is best suited to your teeth.

How to whiten teeth?


Indispensable to take care of yellowed or grayish teeth, the kits of dental bleaching allow to find the whiteness. Indeed, these kits are generally composed of a small lamp and a tray. The latter contains a whitening gel. Teeth whitening kits ensure a quick result because you can see its effectiveness after only 5 days.


However, the whitening products used by dentists are safer and more effective. They have the best equipment, specifically, everything that is necessary to perform a teeth whitening. Indeed, dentists have the right to use hydrogen peroxide, also called hydrogen peroxide, because it has a high concentration of oxygen, concentrated at a maximum of 6% to whiten teeth.

And tooth whitening should really be done at the dentist's for a proper treatment. Hydrogen peroxide is known for its effectiveness on our teeth. And it is thanks to this large quantity of oxygen that the stains will be perfectly eliminated and the teeth will be brighter, and this, in several shades. That said, we can also use urea or carbamide peroxide to whiten teeth.


But it is also possible to do a home tooth whitening. This involves using baking soda on your teeth. Indeed, it is a natural, soft and effective product to whiten your teeth. To use it, simply sprinkle some baking soda on your toothpaste before brushing your teeth normally. It is advised to do it only once a week to avoid damaging the enamel of your teeth.


The most commonly used tooth whiteners are, in fact, products based on less concentrated oxygen peroxide, such as toothpastes or powders, etc.

The different types of dental bleaching kits

Professional bleaching at the dentist

An appointment with a dentist is highly recommended to get the right teeth whitening treatment. This option guarantees a personalized treatment that is best suited to your teeth.

Benefits :

  • An adapted treatment
  • For an optimal efficiency

Disadvantage:

  • Its somewhat high cost

When to choose a professional whitening at the dentist?

An appointment at the dentist is essential for those who want to be safe from the risks associated with an inadequate treatment.

Smile bars

A

little detour to a smile bar is one of the express solutions for whitening teeth. Installed in a comfortable booth, you will have a silicone tray containing a whitening gel of sodium perborate, which will be placed like braces. Your teeth will then be exposed to a pulsed light for about 20 minutes.

Advantages :

  • Optimal comfort
  • Immediately visible results

Disadvantages :

  • Non-compliance with legislation, particularly with regard to the level of chemical products
  • Not adapted to certain types of teeth
  • High risk of irreversible lesions
  • Not very long-lasting effect

When to choose a smile bar?

The smile bar is particularly effective in erasing coffee or cigarette stains.

Tooth whitening strips

These

strips stick directly to the teeth to lighten them and restore their natural shine. However, there are risks to this process, as improper use of the strips can burn the gums, damage the teeth, or cause dental hypersensitivity. It is therefore important to always take precautions when using this type of product, which contains hydrogen peroxide, a harmful agent if overdosed.

Advantages:

  • They are easy to use
  • They are accessible to all

Disadvantages:

  • Risk of irritation and burning of the gums

When to choose a teeth whitening strip?

For a one-time solution, opt for a teeth whitening strip.

White pens

The

teeth whitening pen is a type of brush that applies a whitening product to the tooth enamel. This cosmetic pen gives a temporary optical effect of whitening teeth.

Advantages:

  • It is easy to use
  • It is sold at an affordable price

Disadvantage:

  • Its use poses risks to the teeth and gums

When to choose a whitening pen?

For a bright smile for a night out, a whitening pen is the perfect solution.

Whitening toothpastes

Nothing

better than whitening toothpaste to get rid of stains caused by tea, coffee, or even tobacco. Its sodium bicarbonate content explains the effectiveness of this product. To increase the effect tenfold, it is also possible to add a pinch of baking soda powder to the paste.

Advantages :

  • Simplicity
  • Immediate result

Disadvantage :

  • Risk of attacking the enamel

When to choose a whitening toothpaste?

For whiter teeth after a fairly long treatment, opt for a whitening toothpaste.

Tooth whitening kits

Tooth whitening kits are currently all the rage, especially among the ranks of smile bar enthusiasts. They can actually have the same effectiveness, by providing the treatment themselves, in the comfort of their own home. The kit contains a gel to be applied with a brush, as well as a pulsed lamp.

Advantages :

  • Treatment in complete privacy
  • Immediate results
  • Low cost

Disadvantages :

  • Ephemeral results
  • Abnormal level of peroxide

When to choose a tooth whitening kit?

The whitening kit is an express solution for those who don't have time to go to a smile bar.

Natural solutions

Natural solutions are no match for other teeth whitening procedures. Baking soda and lemon, vegetable charcoal, strawberry paste, or certain essential oils are proving to be miracle ingredients for a pristine smile.

Advantages:

  • They are easy to use
  • They are risk-free

Disadvantages:

  • Their effectiveness is relative

When to choose a natural solution?

If you are concerned about the risks of teeth whitening, opt for natural solutions.

Use a tooth whitening kit or have a scaling?

Using a tooth whitening kit

The tooth whitening kit can be used at home. Correct use is enough to have a bright smile. The whitening process is safe even if not assisted by the dentist. Opt for a whitening kit if you have a special occasion or if you don't feel like paying for a scaling. But you should keep in mind that improper use of tooth whitening products can thin the enamel of the teeth, making them more vulnerable to cavities. It can also increase tooth sensitivity.

Do a decalcification

Scaling is a procedure performed by a professional for cosmetic reasons. The operation consists of removing yellow stains from the teeth, caused by smoking or excessive consumption of red wine, coffee or tea. This process requires the use of special devices, which are not available in stores. However, this method can make your teeth more sensitive because of the chemicals used during the whitening process. Because the physical structure of teeth varies from person to person, the scaling process can affect each person differently.

Verdict

If you have stubborn stains on your teeth, scaling should meet your needs. However, we recommend the dental bleaching kit for a more effective and visible result in a few minutes. In any case, do not abuse these two methods at the risk of increasing the sensitivity of your teeth and making them more vulnerable.

Why use a teeth whitening kit?

The whitening treatment is currently a very popular solution to have white teeth. It must be said that it has many advantages:

1. For a bright white smile

Having a bright smile eliminates the face of men and women. A dazzling white smile, as seen on our TV stars, is now perceived as a symbol of health, charm and success. The popularity of whitening treatments is also due to the effectiveness of these products.

2. For fast results

Choosing professional teeth whitening products can also mean fast results. After three to four weeks of treatment, or even less for the most effective products, teeth should be bright and invigorated. Some products on the market are not only expensive, but also have difficulty achieving such results after two months of treatment.

3. Products that respect the natural color of the teeth

Before prescribing a whitening treatment product, professionals refer to the natural color of the patient's teeth. This avoids any risk of incompatibility. For off-white teeth, for example, products based on sodium bicarbonate or soda do the trick. In practice, you should not forget to brush your teeth regularly, preferably with an electric toothbrush.

4.well-dosed products

Dental professionals are the best people to offer teeth whitening products. They conduct a complete analysis of the patient's teeth before deciding on the right solution. The patient will receive a well-dosed, effective product that does not pose a risk to the inside of the mouth.

5. Products with a normal level of hydrogen peroxide

If you go to a dentist's office, it is possible to obtain teeth whitening products with a hydrogen peroxide concentration of 10%. This composition ensures successful whitening. Note that the rate in question is around 0.01% on many brands of toothpaste. Finally, to increase the desired effect tenfold, all you have to do is brush your teeth regularly for an average of 3 minutes.

6. Optimal acidity level

After a thorough analysis of your teeth, your dentist will suggest the right whitening product. The acidity level of the product should not pose a risk to the patient. It is therefore best to be wary of certain products that abound on the market. Among them are toothpens that are sometimes ineffective. With a too low acidity level, they cannot fulfill their whitening mission.

7. Static products

Dentists are the only ones authorized to dispense kits with trays. These are offered with a custom-made thermo tray to ensure good contact with the teeth. This is necessary to prevent the product from dissolving in the mouth if it is not static. This disappointment is often seen with many kits with gutter proposed on the market.

8. For less risk to your mouth and teeth, go natural

At a time when 100% organic products have become the standard, professionals are offering teeth whitening products made with natural ingredients. These products are manufactured according to hygiene and safety standards, especially for the inside of the mouth. Some grandmother's remedies are also useful. But be sure to ask beforehand, as not all remedies are effective. For example, rubbing lemon on the teeth is very dangerous: the enamel takes a serious hit, to the point of becoming too sensitive.

Tips

Clean your teeth well.

Brush and floss your teeth. Then use the teeth whitening kit.

Be careful with the quantity of products to be used.

Make sure the trays in the kit are dry before you fill them with the peroxide solution, and never overfill the trays. If you apply the gel directly to your teeth, use a toothbrush and carefully cover all exposed surfaces. Be careful not to get it on your gums.

Follow the instructions.

Only leave the gel or whitening strip on for the recommended time. Keeping the product on your teeth longer will not give you better results and may cause tooth sensitivity or damage.

Rinse your mouth.

Avoid coffee, as well as cigarettes. Your teeth will stay white.

Dentures may not bleach.

Some dentures, crowns and fillings will not lighten with whitening treatments. So you may end up with mismatched coloring if you don't replace those dentures.
