Children’s dental health has not improved in 30 years, according to the National Health Survey of 5-year-olds. What’s more, the current COVID-19 crisis has exacerbated inequalities, reduced access to dental care, and will have repercussions for years to come.

This was the backdrop to a webinar presented on behalf of BioMin® to address the issues surrounding paediatric dental health and the work underway to try and improve the situation. It was also an introduction to the new BioMin® F for Kids toothpaste. Sir Paul Beresford, a dentist by background and the MP for Mole Valley, opened the discussion with some ‘appalling’ statistics. There are 160 dental extraction operations daily in England for 5 to 9-year-olds at a cost of £836 per individual per time; and 25% of all 5-year-olds have decay in at least 3 or 4 teeth – a figure that rises to 50% in deprived areas.

He commented that Chief Dental Officer Sara Hurley is campaigning hard to raise the profile of children’s dentistry, with strategies to teach toothbrushing in schools. Together with the CDO and Professor Mike Lennon of the British Fluoridation Society, Sir Paul has met with Health Secretary Matt Hancock to push for a widening of fluoride in the water supply. Sir Paul is a strong advocate of water fluoridation which, he believes, together with the backing of health ministers and effective messaging, ‘could mean we are heading for a very, very strong preventive programme.’

He added that he would like to see a ‘BioMin test ’ run in schools, with the efficacy of BioMin measured against other brands of toothpaste. He’s already raised this with the CDO, ‘and Sara’s on for that,’ he said.

He was followed by Emma Pacey, a dental therapist by training with dual roles at Health Education England and King’s College Hospital. Emma reiterated Sir Paul’s concerns that children’s dental health improvement had plateaued. With a strong correlation between poor oral health and overweight/obesity, tackling this was especially important, she argued.

This was particularly worrying during the current COVID-19 crisis, she said, with inequality proving a huge risk factor – ‘both for infectious diseases like COVID-19 and for conditions such as dental decay.’ Her work involves addressing the complexities of promoting oral health and making sure that the workforce has the necessary and transferable skill set to enable it to meet current challenges. She did see a positive, however, that the current crisis has taught many lessons about the transferability of skills and how to move forward.

Nigel Carter, CEO of the Oral Health Foundation, described how the Foundation was addressing the problems of children’s dental health through its campaigns, but warned too that the reduced access to care under lockdown would have particularly severe consequences on deprived areas – and especially children, in whom decay advances more quickly. ‘As dental practices return to practice, there will be a need to prioritise children,’ he said.

Dr Carter is glad to see a real interest in water fluoridation. ‘It really is going to be a huge step forward and a huge health benefit, and we will be increasingly supporting and promoting it,’ he said.

He did however believe that the COVID - 19 crisis offered a special opportunity for the dental profession to review the way it worked. ‘Uniquely within the history of the NHS, during this period dentists are not being paid to drill and fill, so they have a unique opportunity to step back from their normal practice and move towards a preventive and outcomes related model rather than an output related model,’ he said.

Paediatric dental expert Professor Ferranti Wong agreed that he continued to see large numbers of children with dental decay. This problem had an impact not only in terms of pain, he said, but also in lost sleep, time off school, and on parents missing work. Figures from the Royal College of Surgeons showed a rise of over 24% in extractions among under-4s in the last decade.

While fluoride toothpaste has been with us since the 1960s, doing a good job, Professor Wong felt it had limitations. He welcomed the introduction of BioMin F, containing not only fluoride but also calcium and phosphate to remineralise lost or damaged enamel. He also believed that BioMin would have a valuable place in treating patients with developmental decay or enamel hypomineralisation (MIH) which causes acute sensitivity. Anecdotally some of these patients have benefited from using the toothpaste. ‘BioMin toothpaste might additionally be able to help with this sensitivity, enabling me as a clinician to treat the problem,’ he said. In response to a question about this later, he said he would like to see a controlled trial to prove these anecdotal impressions.

Professor Robert Hill of Queen Mary University of London, who developed BioMin F and is Chief Scientific Officer at BioMin Technologies, briefly explained the action of BioMin F in slowly releasing a low concentration of fluoride, calcium and phosphate ions over a sustained period to raise the pH in the saliva, and form stable fluorapatite for tooth surface remineralisation.

Moving on to the particular issues with children, Professor Hill illustrated that children’s typical frequent ‘grazing’ eating style means that the pH in the mouth is not allowed time to return above 7, causing the mouth to remain on the acid side, causing tooth decay. BioMin F dissolves faster when the pH is lower, he explained, and unlike previous generations of bioactive glass, forms fluorapatite, which dissolves far less readily. Shockingly he warned that during the coronavirus lockdown, consumption of fizzy drinks and crisps had increased by 25-30% over the last three months, with inevitable effects on tooth decay rates.

For those worried about fluorosis, Professor Hill explained that thanks to the slow release mechanism of BioMin F, ‘we can have a caries preventative effect at much lower fluoride content (equating to approximately 540 ppm) ’.

Regarding the guidelines on recommending toothpaste containing fluoride, Professor Hill felt they had ‘some deficiencies’. He said: ‘If you want to make the most effective use of fluoride, you also need a source of calcium and phosphate.’ Studies in the laboratory (see remineralisation graph below) have shown that BioMin F, containing all three, had significantly higher remineralisation rates than other products.


Introducing new BioMin F for Kids, Professor Hill said it has the same active ingredient loading as the adult paste, but with child-friendly strawberry and melon flavours, packaging to engage children featuring ‘Bino’, and a range of materials to make brushing more fun, such as colouring sheets, stickers, and a brushing chart.

Questions followed, and in response to a query about how to engage parents and motivate children, Emma Pacey stressed that messages must be ‘positively framed – no scare tactics’. She added that explaining that ‘what’s good for teeth is good for tummies’ piggybacks neatly on broader health promotion messages, giving people an additional incentive to change their behaviour. She encouraged dentists to work in partnership with other local professionals such as pharmacists and local education workforces. ‘It’s not just about giving advice, it’s about supporting people through behaviour change once we’ve had that initial conversation,’ she said.

Professor Robert Hill responded to a question about further uses of the bioactive glass technology by saying that his team were looking into using it for varnishes, filling materials, and adhesives. ‘The bioactive glass has considerable promise in all these areas,’ he said.

Attendees at the webinar appreciated the interactive question and answer format. Hygienist Jocelyn Harding wrote on Facebook: ‘A great webinar on children’s dentistry. Thank you.’ Gilliano Wallis commented: ‘It was a great style, thoroughly engaging and enjoyable.'
