This is an automatically translated article.

Teeth whitening strips are currently being loved by many people because of their fast effectiveness, low cost, and confident white smile for many people. However, apart from those benefits, is the whitening toothpaste any good? A lot of people speculate about the harmful effects of teeth whitening strips, what is it really like?

1. Are teeth whitening strips good?

There are many brands of teeth whitening strips on the market today. These patches contain teeth whitening ingredients that work on the mechanism of staying on the tooth surface for a certain time to whiten.
Depending on the whitening needs, users often choose a patch containing from 9-14% hydrogen peroxide with a course of 14-20 days of continuous use. So are teeth whitening strips effective?
As with other at-home teeth whitening solutions, the whitening strips have the following characteristics:
Visibly whitening effect, with each use from 30-60 minutes persisting for more than 10 days ( even faster). How to use is easy, just stick to the teeth according to the instructions and wait for a certain time. The cost is much cheaper than the professional whitening measures at the dental clinic. There are many different origins, from the US, France, Korea and even China. Thus, if only in terms of teeth whitening and economics, the whitening paste is considered a "good" and highly effective product.

2. Harm of teeth whitening stickers

The culprit that wreaks havoc on teeth is hydrogen peroxide - a mild abrasive found in many whitening strips on the market. According to dental specialists, the concentration of hydrogen peroxide in teeth whitening products at dental services is 45%, which has a whitening effect within 1 hour under the control of a doctor. After that, a special dental instrument will be manipulated with a bleach concentration of about 10% (considered a safe concentration of bleach). However, with teeth whitening strips advertised as having a "speedy" effect, the concentration of hydrogen peroxide must be higher than 10% to have a quick effect.
How do high levels of Hydrogen Peroxide affect teeth? In terms of tooth structure, there are 3 layers: the thin outer layer is enamel, the lower layer is dentin and the tissue that connects the root to the gums. Most teeth are made up of dentin with high protein and collagen content. After 1 hour of use, hydrogen peroxide will penetrate into tooth enamel and break down collagen protein present in dentin. Because collagen regeneration is very slow, it will be harmful to use too many whitening strips in a short time.
The thickness and hardness of each person's enamel will be different. Users also can not brush their own enamel is strong enough to experience the effects of whitening ingredients at high concentrations, so the risk of causing gum inflammation, thinning of tooth enamel, swelling of the gums, tooth pulp death, prolonged tooth sensitivity is very high.
Especially for people with processed teeth, collagen regeneration is not possible, lost enamel also never returns. Therefore, users should consider for themselves before deciding whether to buy teeth whitening strips or not.

3. Notes before applying whitening strips
