THREE in ten children have rotten teeth by the time they start school, according to official figures.
One report found that 29.3 percent of five-year-olds have some degree of tooth decay.
This is more than half in the worst affected areas.
Health leaders warn about fizzy drinks and junk food are destroying toddlers’ enamel.
It comes as a family struggle to see a dentist rise cash-strapped clinics shun NHS work.
Only 46 percent of the children had a check-up last year.


The Ministry of Health said: “Tooth decay is related to the frequent exposure to teeth to sweet snacks and drinks.
“It affects children’s ability to eat, smile and socialize and causes pain and infection with parents’ missed days at school and work.”
The 2022 Oral Health Survey revealed the state of English children’s teeth for the first time since 2019.
It used checks of 62,649 children and found their grinds were in worse shape than before.
The report said: “There was a decrease in decline in 5-year-olds from 2008 to 2017.
“However, there is no continuation of this improvement in 2019 or in the results of this latest study.”
Statistics show that children in the North West of England were in the worst shape, with 38.7 per cent suffering from decline.
More than half have tooth decay in the hardest hit areas of Cambridgeshire (56.7 per cent), Peterborough (56.4 per cent) and Blackburn (54.9 per cent).
Those in the poorest parts of England are three times more likely to have dental problems than those in the richest.
Eddie Crouch, president of the British Dental Association, said: “Our youngest patients need actions, not words, whether it’s access to basic care, rolling out programs in schools or fluoridating water.”
The 10 areas with the highest rates of tooth decay at age 5 are:
- Cambridgeshire (57%)
- Peterborough (56%)
- Blackburn with Darwen (55%)
- Bolton (53%)
- Brent, London (50%)
- Liverpool (49%)
- Blackpool (48%)
- Camden, London (47%)
- Leicester (47%)
- Salford, Gtr Manchester (44%)
NHS guidelines say parents should brush their children’s teeth once they are over.


They should be brushed twice a day and families should visit the dentist regularly.
Children should also not be given too much sugar, so avoid sweets, lollipops, fizzy drinks and fruit juice.
