Is tooth decay contagious

Dental problems usually occur in children because they have no self-control, have no resistance to sweets, and may not clean their mouths in time after eating, so the chance of getting tooth decay is very high. Many children will ask their parents if tooth decay is contagious after they suffer from tooth decay. Tooth decay has no source of infection and is mainly caused by poor oral hygiene.

1. Is tooth decay contagious?

Tooth decay is generally not contagious because it is caused mainly by the oral environment being acidic for a long time, which promotes the growth and reproduction of bacteria, leading to erosion of the tooth enamel layer and thus caries. Tooth decay caused by tooth decay is not contagious. For example, if the pH value of some people's saliva is more acidic, then the possibility of all teeth suffering from tooth decay will increase as the pH value of saliva becomes more alkaline. But because saliva flows, the infection cannot be transmitted between teeth. Tooth decay should be treated promptly. Due to the large amount of tartar and plaque in the mouth, the poor nutrition of some teeth, and the lack of good preventive measures, it is easy to cause tooth decay in other teeth. However, this is not a problem of tooth decay being contagious, but the direct result of the cause of the disease.

It is very necessary to prevent tooth decay. You should pay attention to maintaining oral hygiene, develop the habit of brushing your teeth in the morning and evening, and rinsing your mouth after meals. At the same time, adopt oral medicine prevention methods as needed, such as children's pit and fissure sealing, local fluoride supplementation, etc., which are effective ways to prevent tooth decay.
