Can fluoride-free toothpaste keep the teeth healthy?
Scientists have been trying to figure that out through a clinical trial of around 200 people. And based on the results of the trial, it was just as effective as traditional toothpaste.
Fluoride is a suitable dose, safe to use, and beneficial for oral hygiene. However, it may be risky to use for children who are habitual swallowers of toothpaste.
To find an alternative, the team of international scientists looked into toothpaste, which uses hydroxyapatite. Moreover, the pharmacies already have some hydroxyapatite toothpaste. The researchers were eager to compare it with fluoride-based toothpaste in a double-blinded, randomized clinical trial. Especially regarding cavity protection. Some experts also warn against fluoride-free toothpaste since some brands do not prevent cavities.
The researchers recruited 189 people between the ages of 18-45. It was an 18-month-long study, and 171 people completed the trial. In addition, half the patients used hydroxyapatite toothpaste, and the other half used fluoride toothpaste.
When the trial ended, they found that 90% of patients in both groups did not have any new cavities. Therefore, the conclusion was that hydroxyapatite toothpaste was “not statistically inferior.”
Co-principal investigator and corresponding author of the study, Professor Elzbieta Paszynska, said,
Hydroxyapatite is a safe and effective alternative to fluoride in caries prevention for daily use,
The final question is whether people will be using fluoride-free toothpaste in the future.
The study has proven that hydroxyapatite toothpaste may be a useful alternative for adults who have fluoride allergies. In addition to those who avoid using fluoride due to medical conditions.
Paszynska further explained,
Previously published clinical trials also show the caries-preventing effect of hydroxyapatite in risk groups such as children and patients undergoing orthodontic therapy
With our new clinical trial, it has been shown that hydroxyapatite prevents dental caries in adults. This is important from a public health perspective.
