Scientists Develop A Safer Tooth Paste For Children Without Fluoride

In Education

Scientists created a toothpaste for children that improves bone strength using hydroxyapatite instead of fluoride. The new formulation poses no higher risk of cavities compared to fluoride toothpaste, as shown in a study. Unlike traditional toothpaste, it avoids potential joint damage from fluoride ingestion.

Hydroxyapatite safer alternative for caries prevention

Poznan University of Medical Sciences’ Professor Elzbieta Paszynska, the study’s co-principal investigator said that hydroxyapatite is an effective and safe fluoride alternative in prevention of caries for everyday use.

Hydroxyapatite, similar to calcium, is safe for human consumption and strengthens the skeletal system. Studies suggest it protects against gum disease, prevents cavities, and reinforces broken tooth surfaces.

Most toothpaste contain fluoride, posing health risks, especially if swallowed by children. Tooth enamel, which is the hardest part of teeth, is made up of hydroxyapatite. Despite being harder than steel  it is prone to chipping if misused to things like opening a bottle.

Paszynska said that currently, the focal point of dental care revolves around embracing the concept of ‘minimally invasive dentistry’ on a frequent basis. The primary objective is to conserve maximum tooth tissue, even in cases where initial caries has caused alterations but still demonstrate the potential for remineralization. The utilization of remineralization compounds represents a significant advantage as it helps curtail the necessity for intrusive carious lesion treatment involving drilling.

Hydroxyapatite and fluoride have similar effect in new cavities prevention

In a study with 171 participants aged 18 to 45, lasting 18 months, the use of hydroxyapatite or fluoride toothpaste showed similar efficacy in preventing new cavities. Almost 90 percent of the participants experienced no new cavities. The participants received neutrally packaged toothpastes, electric toothbrushes, and replacement heads. They were instructed to brush their teeth twice daily for three minutes after meals, without altering their diet.

Participants visited clinicians every six months for an examination and received a new supply of toothpaste, including a plaque disclosing solution to assess teeth cleanliness. The study concluded that there was no notable difference in effectiveness between those using hydroxyapatite toothpaste and the control group.
