Research shows sharing of cavity-causing bacteria may not be only from mothers to children
New ongoing research is showing more evidence that children may receive oral microbes from other, nonrelative children. It was previously believed that these microbes were passed primarily from mother to child, but in a recent study, researchers found that 72 percent of children harbored at least one strain of the cavity-causing Streptococcus mutans not found in any cohabiting family members.

Nanoparticles used to break up plaque and prevent cavities
The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can 'hide' within a sticky biofilm matrix, a glue-like polymer scaffold. A new strategy took a more sophisticated approach. Ref. Source 3e.
Genetic defects in tooth enamel conducive to development of cavities
Bacteria are not the sole cause of cavities; tooth resistance also plays an instrumental role. Researchers demonstrate that mutated genes lead to defects in the tooth enamel and can therefore encourage the development of cavities. Ref. Source 5y.
An end to cavities for people with sensitive teeth? An ice cold drink is refreshing in the summer, but for people with sensitive teeth, it can cause a painful jolt in the mouth. This condition can be treated, but many current approaches don't last long. Now researchers report the development of a new material with an extract from green tea that could fix this problem -- and help prevent cavities in these susceptible patients. Source 1m.
