After each meal, 3 times a day and for 3 minutes is what we taught children about brushing. And the truth is that although we brush correctly is not always true. Sometimes what we know about oral health is not always right.
For example, brushing your teeth immediately after eating is one of the most common mistakes and it seems logical to think that it is the best time but the fact is that if we do we will be rubbing the acid ingested against our teeth.
REASON WHY YOU SHOULD NOT BRUSH YOUR TEETH AFTER EATING
This is the biggest enemy as far as care is concerned, making the effect stronger and longer, this weakens and demineralizes the surface of the tooth since we would be lowering the pH of our mouth.
Being thus more prone to caries. So correct is to wait at least half an hour before brushing your teeth after eating. Since our own saliva will decrease the level of acidity. So if you are in a hurry it would be best to rinse your mouth with water in this way pH levels will be within normal range.
At work it is advisable to have a little mouthwash so that the plaques are not acidic. This is healthier than brushing after eating. It is advisable to chew gum or cheese to help us produce saliva as this is the best mechanism to reduce acid levels in the teeth.
The cheese helps to reduce the pH of the bacterial plaque and has elements that help the teeth. The chewing gum if sugar besides helping us to salivate possesses xylitol a sucrose substitute that apart from sweetening has anti-cancer properties.
