Teeth whitening pencil - application features, effectiveness, reviews

Special pencils for whitening teeth appeared in the lines of many European, and a little later, Chinese manufacturers. They are tubes that contain a special whitening gel. To apply it, use a brush, brush or sponge. The amount of gel can be dispensed, but the required volume is always indicated by the manufacturer on the package.

Application features

The most important advantage of this method is convenience. Teeth whitening at home with a pencil does not require almost any action. All that is needed is:

1. rinse your teeth after eating - it is advisable to carry out the procedure precisely after eating, because in the future it is required to refrain from eating and drinking at least an hour;
2. wipe them dry with a napkin - it is important for the normal action of the gel;
3. apply gel on teeth - the active substance begins to foam;
4. tolerate with an open mouth for 1-10 minutes, depending on the manufacturer's recommendations;
5. rinse the gel with water or do nothing - this is also indicated by the manufacturer, as some gels simply evaporate from the surface of the teeth while whitening the enamel.

Each manufacturer notes on the package how to use a tooth whitening pencil. Different products have nuances of use. Common aspects for all are:

• frequency of use - apply the gel 2 times a day;
• course duration up to 2 weeks;
• effectiveness only if at the time of whitening you avoid the main factors that led to the darkening of the enamel: coffee, cigarettes, pomegranate juice, red wine, other dyes. Having them in your life reduces the effectiveness of your whitening pencil. Instructions to it, by the way, usually do not indicate this.

How does a bleach pencil work?

And now let's see why a whitening pencil (pen) with aliexpress for teeth is able to lighten enamel. The reason lies in the composition of the gel. Its active ingredient can be the following compounds.

• Hydrogen peroxide - its concentration is low, it is 5-12%, but this is enough to cause deep damage to the enamel if you overexpose the composition on your teeth. Peroxide reacts with oxygen, which activates the removal of plaque from enamel.
• Urea Peroxide - in fact, this is the same peroxide, only slightly weaker. The peroxide content in the gel usually does not exceed 15%. When applied to the teeth, it also activates the release of oxygen, but acts in a more gentle way. The approximate difference in the intensity of exposure to hydrogen peroxide and urea peroxide is 3: 1.

In addition, other substances can be included in the gels, for example, enamel mineralizers (phosphorus, fluorine, calcium), natural flavors, bactericidal agents. Each such additive improves the action of the pencil, reduces the aggressive effect of its main component. Therefore, reviews about a tooth whitening pencil recommend that you buy enriched formulations.

What could be the consequences

• Increasing tooth sensitivity - always happens. But manufacturers warn about this, so claims, it would seem, should not be. However, they arise, since this sensitivity does not pass by itself, but only increases as the means is used.Only special toothpastes can eliminate it.
• Conditional enamel brightening - Unfortunately, manufacturers do not warn that the use of only one pencil is not able to bring tangible benefits. An integrated approach is required: professional cleaning in dentistry, refusal of coffee and smoking, coloring products and the additional use of a pencil as a support tool.
• Enamel destruction - develops when using the product without consulting a dentist. If the enamel initially had cracks, the product significantly exacerbates the problem.

Reviews

• Natalya Borisenko, Luxury Whitepro pencil: “I am an employee of a dental store. And I assure you that as an independent tool, the pencil does not work.

• Irina Kravchenko, Bliq teeth whitening pencil: “Only my teeth ruined myself with this pencil. At first, when I started to smear, my teeth became lighter, and after 6 days they started to ache so that I ran to the dentist. She told me that cracks appeared on the enamel, scolded, but you can’t help your teeth anymore ... ”
• Tatyana Ilyina, Teeth Whitening Pen: “I haven’t noticed any effect at all, maybe the enamel has brightened, but by a tone, not more. But the teeth began to whine and ache. In general, after about a week I stopped using it. ”
