Previously, to look respectable, it was enough just to have a full set of teeth. Now, to maintain the social status of the teeth it is desirable to have not only healthy, but also beautiful.
Aesthetic dentistry has reached such heights that almost every person with a certain financial freedom can find a beautiful smile. How and how to effectively and harmlessly whiten your teeth at home, saving time and money?
How can you whiten your teeth quickly and without harm to the enamel
The International Association of Dentists unequivocally points out that even simple home bleaching by popular methods should not be carried out without the advice of a dentist. The structure of dentin and enamel, their structure and defects, tolerability of various substances are individual for each. 
However, this does not mean that you can not safely deal with home procedures. Just talk to your doctor. Maybe you have the same case when teeth can not be whitened without losing the quality of life, and you will have to resort to a different method - vinification or nanocoating.
Still better to live fully with darkish healthy teeth than with white, but hypersensitive and unfit for contact with cold, hot, sour, spicy food and drink.
To whom it is undesirable to bleach teeth at home
- To people suffering from special sensitivity of gums and teeth.
- Wearing crowns, veneers and seals on the front teeth. Artificial dental tissue does not bleach in parallel with the living tissue. In this case, the dentist preserves the fillings and crowns, whitens the living tooth tissue, and then - the artificial parts of the tooth. Or simply replaces them with new fillings or crowns - under a new shade of teeth.
- To people with gray or black teeth. Yellow teeth lighten quickly enough. But grayish-black or brown tones mean the defeat of the deep layer of teeth - dentin. Perhaps because of the antibiotics of tetracycline or because of fluorosis.
- People with teeth blackened by trauma or after removal of nerves and canal filling.
- People with periodontal disease, periodontitis or dental caries. First you need to be cured.
If you do not belong to any of these groups or decide to take risks when consulting with a dentist, there are many opportunities for you to whiten your teeth. Let's talk about them.
Whitening strips for all types of tooth enamel
Strips can be of several types: classic, intense, especially sensitive enamel. The concentration of the active substance in them is different, so strips are applied at different times - from 5 to 30 minutes.
But it is important to follow the recommendations strictly, because an intense gel, imposed for a long time, can cause inflammation, itching and even pain in the mouth and teeth.
How to use strips? 
- Clean teeth in the usual way.
- Remove product, remove protective film.
- Stand at the mirror, apply the gel strip to the teeth, smooth, press to the teeth, repeating their shape. For better distribution of the gel, the extra edges of the strip can be folded.
- After the proper time, remove the strip.
- Rinse or gently clean the teeth.
- Strips apply twice daily.
- Do not eat or drink while you are stripping, do not smoke, do not talk, so that saliva does not stand out - this will spoil the effect.
Perhaps the most common brand that produces tooth stripes is Crest. The active substance is hydrogen peroxide, which bleaches only the living, natural enamel of the teeth. Clarifies teeth to 2-5 tones on the Vita scale.
Tooth whitening with stripes - recall:
Plus from using stripes - in their comparative cheapness. The kit, which is enough for a month, costs 25-40 dollars, and the result is 2-4 months. Then the course is repeated, it is possible with a more gentle, supporting gel.
Minus strips often cause discomfort to those with sensitive teeth and gums.
In general, they are safe for the teeth and do not change the structure of the enamel.
Gel for stronger teeth whitening
Two other forms of gel whitening - pencil sticks for bleaching and kapa( optional writing - kappa) with dental gel. Most of the drugs in this group are based on hydrogen peroxide with softening, compensating additives and taste improvers.
Inside the mold, a 10-35% whitening gel is lubricated. A strong, 35% gel with hydrogen peroxide is used for half-whitening.10-16% is laid in the kaps at night( from 6 to 8 hours).Gel for cap is sold in syringes. 
Method of application:
With a brush or syringe applicator, the gel is applied to the inner surfaces of the kapa and
subsequently, when properly seated, falls on the enamel of your teeth.
This method is good because for a month it allows you to bleach the enamel by 6-11 tones on the Vita scale. Another advantage is that the kaps are individual, fit tightly to the enamel of the teeth, so the whitening turns out to be uniform and strong.
Yellow teeth become white after a week of application, and the visible effect can be achieved in 1 evening. A stable result appears in the first week. The course of bleaching usually lasts 2-4 weeks and lasts up to 4-5 years. 
The stability of the effect depends on the lifestyle. Those who love tobacco, coffee, black tea, red wines, dark carbonated beverages, juices, beets and spinach change their teeth color faster. There is one tricky trick: coloring drinks can be drunk through a straw - this will significantly reduce the intensity of staining.
Causes - uniformity and intensity of bleaching and the ability to sleep in drops( without spending active time on bleaching).This creates a strong psychological effect: it went to bed, and in the morning - yellow as it was, the teeth are beautiful, the smile is bright.
This method is particularly suitable for smokers, as it removes nicotine yellowing and penetrates deep enamel layers.
Toothpaste for whitening, video
With them it's simple: pastes give a relatively modest whitening effect for 1-2 tones. These pastes can be used regularly, but not more often than twice a week, because they have abrasive particles, and with frequent use, the integrity of the enamel suffers.

Soda is used as a tooth powder or mixed into a habitual toothpaste.
But nevertheless in it there are enough large abrasive particles which can damage a mouth or enamel. Therefore, clean the enamel soda should not be more than once a week.
How to whiten tooth enamel with hydrogen peroxide
Hydrogen peroxide as a tooth whitener has been used since 1880 and ranks second in popularity. Many combine bleaching with hydrogen peroxide and soda, applying each of the methods once a week. And in general, peroxide is the main ingredient of most chemical brighteners.

How to whiten your teeth with a banana
More precisely, its skin. By the way, this little-known method is good because it whitens both natural and artificial enamel - fillings, extended teeth, crowns. 
Often removes a noticeable boundary between natural and artificial enamel. Therefore, older people actively use the method when they want to hide the artificial origin of a part of the teeth.
Darkening of artificial enamel is as natural as the change in the color of the natural enamel of the teeth, but these two processes pass unevenly, which makes the teeth look like piano keys.

How to whiten teeth to children
Teeth are not finished in children 0-10 years old and adolescents 12-16 years old, so whitening is not recommended. It is necessary to wait for the enamel ripening, which occurs by the age of 16.Often children and adolescents are caries( up to 90% of the population) and gingivitis( inflammation of the gums) as a result of non-compliance with oral hygiene and hormonal imbalance. 
Therefore, our advice: teeth whitening in a child is possible only by sparing plant methods or after consulting a dentist. In the overwhelming majority of cases, it is enough to clean the equipment twice a year, so that your child's teeth are beautiful and healthy. And, of course, it is necessary to timely cure gingivitis and caries.

Also people who wear braces are recommended to combine home whitening procedures with professional ones. It is better that this is a quick procedure, for example, Zoom, when the gel-bleach is activated by means of an ultraviolet lamp.
How to whiten tetracycline teeth at home
Tetracycline teeth are less suited to whitening. The fact is that the spots lie not on the enamel itself, but in the deep layers of the tooth. This is what makes darkening persistent and deep. 
The cause of darkening is the use of tetracycline antibiotics. And the destruction affects even the rudiments of the fetal teeth in the womb of the mother, who takes the antibiotic. Tetracycline is not excreted from the body, it is collected in bone and dental tissues.
Tetracycline darkening is manifested in three degrees:
- Local staining in the form of spots and streaks. This color is amenable to whitening both at the dentist and at home.
- Staining has an average degree: brown, yellow or gray teeth without streaks and stains. Whitening is possible at the dentist, and at home.
- Deep degree of staining. Intense color, large layers of dyeing, covering the teeth with stripes. Whitening does not give a satisfactory effect, it may be necessary to have vinification, crown replacement or nanocoating.
Tetracycline teeth are well suited to photobleaching using lamps that activate the gel applied to tooth enamel. This photobleaching clarifies the painted teeth by 9-12 tones on the Vita scale. 
Sometimes used internal bleaching. It is, of course, impossible to do it yourself at home. In this case, the whitening substance is injected into the inside of the tooth, into its channels, and covered with a temporary filling.
It is impossible to effectively whiten teeth affected by tetracycline in one hour, so it is necessary to take the procedures in advance. Often answers to mail.ru inspire people with false optimism that one can get rid of deep yellowing in one evening. This is not true.
And so that it went right, you need to consult a dentist. It's hard to whiten such teeth without harming the enamel.
Important: when bleaching tetracycline teeth, remove the stone with pre-cleaning. Cleaning - gentle non-invasive operation, takes no more than half an hour. Ultrasonic waves are directed to the surface of the teeth, after which they are rinsed.
The main reasons that prevent your teeth from remaining white
- The use of refined, processed foods with dyes, colored drinks and sweets, coffee, black teas, red wine, dyeing vegetables and fruits.
- Irregular, abnormal or insufficient brushing of teeth. How to properly brush your teeth, the dentist will teach, there is nothing shameful about it. By the way, most adults do not properly brush their teeth. You can see and training video on the Internet.
- Do not use rinse or dental floss.
- Uncleaned language. Yes, the language, too, must be cleared in the morning from a raid.
- No hardware cleaning( 2 times a year).
- Poor environmental conditions, aggressive substances in the environment, including iodine, lead, mercury, bromine.
- Pathology of internal organs. After unsuccessful bleaching, it makes sense to undergo examination - pathological processes inside the body that stain the tongue and teeth are possible.
Before deciding to whiten your teeth at home with folk remedies or using the newfangled methods, it is important to realize that after this procedure the enamel of the teeth will be particularly vulnerable for some time.
It is necessary to abandon bad habits and coloring food, and then the teeth, with a good selection of hygiene products, will always be healthy and white.
