Scores of tots are having their teeth removed because of decay.
In England last year 83 kids under two had at least one rotten tooth pulled, according to NHS Digital figures.
And nearly 36,000 children aged from two to 17 had one removed – while 54 kids aged nine or under had all their teeth out last year.
In total across England 2,806 patients had the procedure.
The British Dental Association is worried some children are not getting their free checks as their parents do not go to the dentist – and do not take their kids either.
An estimated one in five adults put off seeing a dentist because of the £22.70 charge for a visit.
The BDA said childrens’ lack of attendance puts more pressure on the NHS. There are also fears some parents are putting fizzy drinks and sugary milkshakes into babies’ bottles causing their teeth to rot.
Dentist Lauren Harrhy, from Pontypool, Torfaen, revealed: “I’ve seen a two-year-old having to have nearly all of his teeth taken out – it’s quite distressing.”
She urged parents not to put sugary drinks into babies’ bottles and pile sugar on fruit as it can be such a challenge to persuade children to clean their teeth.
She said: “It still happens, not as much coke, but we do see it.
“But lots of people say: ‘I thought I’d put a bit of milkshake in because they like it’, but milkshake is as sugary as coke.”
NHS chiefs in Wales rolled out the Designed to Smile scheme in 2009 in nurseries and schools in some of the most deprived communities.
It came after shock figures showed that half of under-fives were living with tooth decay in Wales.
The scheme, which included putting fluoride varnish on children’s teeth, has helped to reduce the number to a third.
But the BDA said that more needed to be done as only 27 per cent of 355 practices it surveyed were taking on new NHS patients.
