Toothpaste plays a crucial role in the oral hygiene as it provides fresh breath and prevent cavities. However, some experts maintain that toothpastes might be harming the oral microbiome.
A study conducted by Niamh Coffey, Albert Leung, and Isabel Olegário, RCSI University of Medicine and Health Sciences revealed that the mouth is one of the most densely populated microbiome environments, home to more than 700 species of bacteria.
The microbiome of the mouth is essential for regulating the pH levels, breaking down food and also producing natural antimicrobial compounds. According to the researchers, many toothpastes contain fluoride that helps in preventing cavity and strengthening tooth enamel. The team highlighted that fluoride also makes it harder for acid-producing bacteria like Streptococcus mutans to cause tooth decay.
According to the study, the anti-bacterial agents present in toothpaste can reduce both harmful and beneficial bacteria. Consequently, it disrupts the microbiome environment inside the mouth. There are ongoing studies on improving the quality of toothpastes so that they can kill the harmful bacteria, while keeping the helpful bacterial environment intact.
In the study, the researchers emphasised on brushing with fluoride toothpaste and cleaning between the teeth twice a day to reduce the bacterial load inside the mouth and also reduce the risk of oral diseases.
