For me, teeth whitening is not a trivial procedure, but a necessity, because I treat smokers and coffee lovers, and my teeth are constantly turning yellow. Probably, I do not brush my teeth very carefully, which also does not positively affect the color of the enamel of my teeth.
As the dentist explained to me, the teeth are white not because they have a high calcium content, but because I have such a genetic predisposition. Even the enamel, which is distinguished by its strength and rich calcium content, can have a yellowish tint.
There are a lot of these methods, and I tried several of them.
1. Special whitening paste. This method is considered the most simple and inexpensive, although not effective enough. When I used this paste, I only achieved what I took off the patina, and the color of the enamel remained the same. By the way, for a long time, more than one month, you cannot use such a paste, so as not to damage the tooth enamel.
2. Activated carbon. I bought coal at the pharmacy. At first I pushed him, then put it on the brush and brushed my teeth with this powder. I cleaned off the swoop quickly, and the tooth enamel underwent a slight abrasive effect. The whitening effect is still small, but there is no danger to the enamel. The main thing is not to press hard when cleaning the toothbrush, so as not to scratch the enamel.
3. Lemon or baking soda. I tried to whiten my teeth with lemon peels, rubbing them into my teeth. Also used the method of grinding teeth with gauze soaked in a solution of soda. These methods are also simple and effective enough, but often you should not use them in order not to cause damage to the enamel and not to increase the painful sensitivity of the teeth.
4. Special gel. I consider this method the most professional of all that you can use yourself. There is a special whitening gel on sale, which is sold by dentists. But you need to get advice from them about the use of the gel.
The first method using the gel is to apply it on the teeth with a special brush. The gel gradually hardens, and then saliva washes away for some time. In order to achieve a good effect, I applied the gel for three weeks, ensuring bleaching for a long time.
The second method is to use mouth guards. I filled this special mouthguard with gel and put it on the teeth at night. Whitening is improved by prolonged donning of the mouthguard. I liked the fact that my teeth were whitened at the time when I was resting.
