Tooth decay is a common disease in children and adults. It is caused by bacteria present in dental plaque. This plaque forms when bacteria in the mouth feed on sugars in food and turn them into acids that attack tooth enamel. If plaque is not removed by regular tooth brushing, it turns into tartar, a hard substance that can lead to tooth decay.
Until then, it was established that the main culprit of dental caries was Streptococcus mutans. However, the study published in Nature Communications reveals the existence of another bacterium, called Selenomonas sputigena, which plays a major role in the formation of dental caries. This bacterium, hitherto only associated with gum disease, would form a multicellular structure in the shape of a honeycomb thus trapping the clusters of streptococci within the dental plaque, promoting their proliferation and thus contributing to the production of acid. , a key virulence factor in dental caries.
A better understanding to prevent dental caries
The researchers took dental plaque samples from 300 children between the ages of 3 and 5 to analyze bacterial activity and uncover the role of Selenomonas sputigena. Thanks to this discovery, it is possible to better understand how this disease develops and therefore to find more effective ways to prevent it.
This study may thus lead to new ways to take care of one’s mouth and avoid dental caries. Oral hygiene practices play a key role in preventing these. It is recommended to brush your teeth regularly, use dental floss and mouthwash. In addition, a healthy and balanced diet is also important for the health of your teeth. This includes limiting the consumption of sugar and sugary drinks, which are the main culprits of tooth decay.
Dental caries, a real public health problem
Dental caries is one of the most common pathologies worldwide. In some countries, it affects up to 90% of the population. Dental caries is particularly common in children and adolescents, but can affect all age groups. Most of the population is affected by dental caries at one time or another in their lives. Apart from tooth pain, untreated cavities can lead to complications, such as tooth infections, tooth abscesses, and even tooth loss.
