While the toothbrush is used to remove the bacteria deposited and attached to the surface of the teeth, or the so-called “tartar” that was formed due to food residues, the dentist Abdulaziz Al-Qarni stated that it transmits infection if it is not properly maintained, as viruses and bacteria can live on the surface of the brush So it causes diseases to people without their knowledge.
Al-Qarni pointed out that the toothbrush differs in its design in terms of the number of bristles, their thickness, and the type of material they are made of, but studies have shown that its function does not differ from each other according to the design, and it may be a source of bacteria accumulating and depositing it between the bristles, changing its color or shape, which leads to a reduction in its function. And their removal of bacterial deposits, which makes them a source of transmission or infection again, especially infectious diseases such as (influenza, mouth sores, or herpes simplex virus, corona, hepatitis virus, AIDS), noting that the toothbrush must be changed periodically every 3 or 4 months or change when its color or shape changes even before this specified period.
A dental repair and cosmetic consultant, Abdullah Al-Yahya, explained that if a person is infected with an infectious disease and then recovered, he must change the brush immediately, as well as a medium-rough brush with equal bristles should be used to avoid any pain or blood leakage when molting, and parents must provide their children with a dedicated brush for them , And it carries certain specifications for their age, such as the small size of the brush that has bristles consistent with the size of their small teeth, and it is recommended that the brush be covered and placed in a safe place that prevents insects from reaching it, and there is no doubt that its use from one person to another is completely prohibited because it transmits many diseases, the most important of which is decay. And when using a person’s brush with bleeding gums, this infects the other person with the hepatitis virus, indicating that the use of dental flossing is important and complementary to hygiene, as the brush cleans 70%, and flossing 30%.
