It is popular that it is better to brush your teeth immediately after awakening, so that the microbes accumulated overnight do not get into the stomach from food. We decided to check if this is so.
Information that bacteria from the oral cavity They can get in the stomach along with breakfast and harm health, you can Meet on sites many dental clinic, on medical resources And Portals O style life. Users discuss whether to brush their teeth in the morning before meals, on various forums And in services questions And answers.
In the mouth of a person It lives About 700 types of various microbes. Not all of them are harmful: some contribute to the digestion of food or restrain the growth of the number of their pathogenic counterparts. Others can cause caries and diseases of the gums. Saliva, which also contains “good” bacteria, helps to restrain the growth of the number of bacteria in the mouth. During sleep, the process of salivation Slow downso the highest concentration Bacteria in the mouth of a person happens immediately after awakening. Some of them are really gets In our gastrointestinal tract (gastrointestinal tract) along with breakfast.
However, this happens in the same way when swallowing saliva, and if breakfast can be postponed “after brushing your teeth”, then the salivation process (and, accordingly, swallowing and getting saliva into the gastrointestinal tract) cannot be controlled. Normally a day in a person's mouth stands out About 750 ml of saliva. In total, 1 ml contains about 100 million bacterial cells, most of which enter our stomach when swallowing. At the same time, our body has a "built -in" protection in the form of gastric juice, which contains acid In a concentration sufficient to destroy swallowed pathogens and restriction of bacterial reproduction in the stomach.
Swearing is not the only possible way to get bacteria of the oral cavity into other internal organs. For example, through wounds in gums, they may be in blood flow, and with it spread throughout the body. In the process of breathing, bacteria may be in Light And cause bacterial pneumonia. So the brushing of teeth - neither after breakfast, nor before - does not guarantee complete protection against the spread of pathogens of the oral cavity to other organs.
“Verified” could not find a single authoritative scientific study that would prove that the time of brushing the teeth in the morning-before meals or after-somehow affects the probability of bacteria of the oral cavity and their harm to our gastrointestinal tract. At the same time, experts Markthat the effect of bacteria of the oral cavity on the health of other internal organs has not yet been investigated.
In general, dentists recommend brushing your teeth after breakfast. For example, this Opinions The UK National Health Service (NHS) adhere to. With them agree and experts of the Australian Health Department. Experts of other authoritative dental associations do not give accurate recommendations when it is still better to brush your teeth - after breakfast or before. So, the British Foundation for the Health of the Cavity advises Do this before bedtime and "at least once during the day." Experts of the Canadian Dental Association They saythat ideally you need to brush your teeth after each meal or at least at least twice a day - before bedtime and during the day. “Verified” did not find a single authoritative medical organization that would recommend brushing his teeth to breakfast.
However, the same NHS experts Recommend Brush your teeth no earlier than 30 minutes after consumption ”acidic»Food (that is, the one whose pH is below 4.6), so as not to injure the enamel toothbrush, and so weakened with acids. To such food Relate, for example, fruit juices, jams and even eggs - Quite popular ingredients for breakfast. U coffee PH is slightly higher than this value, and nevertheless, some nutritionists also attribute it to the "sour" drinks. Specialists of the American Dental Association Consult Wait after eating for at least an hour. Therefore, if you do not have time for such a large break between breakfast and brushing your teeth, it is better to clean them immediately after awakening.
In addition, brushing the teeth for a while stimulates salivation (research Showed different Duration This effect is from 5 to 60 minutes). This, in turn, can help with digestion of food eaten for breakfast and protecting the oral cavity from the reproduction of bacteria, so there are also some advantages of the choice of such a cleaning time.
Thus, no authoritative medical or specifically dental organization gives recommendations to brush your teeth before breakfast, and some, on the contrary, even advise doing this after eating. “Verified” could not detect a single serious scientific study that would confirm that the time of brushing the teeth in the morning somehow affects the occurrence of health problems caused by swallowing the microbes of the oral cavity. In addition, normal in the human body has mechanisms of protection against them - acidic acid acid kills pathogens. Nevertheless, there are also some advantages of teeth brushing before breakfast, but they are in no way connected with the hypothetical swallowing of bacteria.
