Five-year-olds in the most deprived areas of the country were more than twice as likely to have experienced decay (32.2%) compared to those in the least deprived areas (13.6%).
In addition, the survey found disparities in the prevalence of decay by ethnic group, with significantly higher percentages in the ‘other’ ethnic group (45.4%) and the Asian or Asian British ethnic group (37.7%).
Regionally, the north west had the highest prevalence of decay, with 28.7% of five-year-olds likely to have experienced it. At a local authority level, Brent had the highest rate with 43.4%.
The survey, which collected data during the 2023-24 school year, also found that the decay rates in four regions have worsened: London, Yorkshire, the south west and the north east.
Overall, the report states that 22.4% of five-year-olds from the survey had experienced decay – a slight reduction from 23.7% in 2022. Among these school children, each child had 3.5 teeth with decay on average.
In addition, the prevalence of decay decreased significantly from 30.9% in 2008 to 23.3% in 2017, but this stalled in 2019 and 2022. However, the recent report shows a slight decrease from 23.7% in 2022 to 22.4% in 2024.
The report states: ‘Inequalities in prevalence of experience of dentinal decay in five-year-old schoolchildren significantly reduced from 2008 to 2015 but there has been little change in inequalities since then.’
Decisive action needed
As a result, the British Dental Association (BDA) has called for decisive government action, warning that the oral health gap risks widening without it.
BDA chair Eddie Crouch said: ‘This oral health gap was made in Westminster, with children paying the price for official failure to take dentistry seriously.
‘A new government calls this “Dickensian”, but it will take deeds not words to turn this around.’
The ‘Read all about it’ rapper told the BBC he only realised the negative physical and mental health impacts of neglecting oral health later in life. He said he now took his own son’s toothbrushing routine very seriously alongside a healthy diet.
