Brushing Secrets

Unlike the title of the comment there is no secret. To have teeth "clean" and keep the periodontal area healthy, it is necessary and sufficient to remove the "totality" of the plaque.
Toothpaste still represents only a very small part in this result. It has a little by changing the surface tension as all know.
What matters is that the toothbrush bristles are in contact with all surfaces of every tooth, every day. It is not easy, he shall be called "technical" brushing and once per 24 hours is sufficient.
You can comfort brushing after every meal which will be much less extensive.

It is quite possible to achieve this result with a manual toothbrush; Colgate or Signal makes excellent. Their disadvantage is that they are quite large, it takes a good 2 minutes to arrive at a correct result and that the inner surfaces of the lower teeth are almost unattainable in some people.
There is a solution to all this! An electric toothbrush, small, easily going everywhere, and making the right move for you! Broxodent that has existed for 40 years and too ignored even professional
Only problem: the price and its limited distribution
