The oral microbiome has a role in initiating tooth decay but it is not necessary to kill these bacteria to prevent tooth decay. What most people don\u2019t know is that bacteria in the oral cavity start taking an action right after a dentist scrapes the enamel or plaque from the teeth.\r\n\r\nWithout stopping sugary and high carb foods, there is no way that bacteria would not build a biofilm and start to corrode the enamel eventually causing cavities. That\u2019s why children are advised not to eat candies, gummies, and other sweet things for saving them from cavities.\r\n\r\nBut researchers have now come up with a new way which can put an end to all this. This new treatment can prevent plaque formation and risk of cavities development at the start. It uses a unique cerium nanoparticle formula which is directly applied to the teeth by a certified dentist.\r\nAlso read- Is Meditation Walk Helpful to Reduce Stress?\r\nThis research project will be presented in the Virtual Meeting & Expo under the American Chemical Society (ACS) for Fall 2020.\r\n\r\nThe human mouth is a house to more than 700 types of bacteria which is called the oral microbiome, says Russell Pesavento who is the lead investigator in this project. He also says that some of these bacteria are beneficial which aid in digestion and metabolization.\r\n\r\nIn addition to this, the oral microbe also contains some bacterial species which are harmful to health, for example, Streptococcus mutans. Once the dentist clears the teeth, these bacterial strains adhere to the freshly clean teeth and start to replicate.\r\n\r\nThey use sugar as their building material and rely on it to grow. Once a thick film forms, it is almost impossible to remove all these bacteria from the mouth by brushing. The metabolization of sugar leaves acidic byproducts behind which damage the tooth enamel and develops cavities.\r\n\r\nDentists recommend using products that have fluoride in them. This fluoride helps to inhibit plaque as well as silver nitrate to prevent tooth decay. The researchers have also come across nanoparticles that are made out of zinc oxide, silver, and some time copper oxide too. These nanoparticles can reportedly treat all types of dental problems.\r\n\r\nBut a repeated usage of these products can cause stained teeth and developing bacterial resistance says Pesavento, from the University of Illinois at Chicago. He also highlights that these agents work in general and may also kill some beneficial bacteria in the oral cavity.\r\nAlso read- Why Racism is a Public Health Crisis and What Does it mean?\r\nThat\u2019s why researchers are working to find a better alternative than doesn\u2019t target the beneficial bacteria but still prevents tooth decay.\r\n\r\nPesavento and his colleagues have come up with a new type of nanoparticles made with cerium oxide. They evaluated the effects of cerium oxide on oral microflora checking if it kills beneficial bacteria or not. \u00a0Although they have only considered some clinically important bacterial strains but these nanoparticles have shown much better results than previous types of nanoparticles.\r\n\r\nThis new type of treatment is significant as it is less damaging for the overall bacterial load in the oral cavity. The nanoparticles only stop the bacteria to adhere to the teeth and create biofilms. So the beneficial bacteria are unharmed in this type of treatment.
