Tooth decay - special report

...Public Health England suggests part of this improvement may be down to increased levels of fluoride in most children’s toothpastes.
Dr Gill Davies of the Greater Manchester Public Health England Centre said: “This survey shows the numbers of five-year-olds free from tooth decay has improved, but there is still much to do to reduce the inequalities in levels of dental decay,
“Good home care is the key and parents should brush their child’s teeth twice a day, once just before bedtime and once in the morning.
“The same factors which affect people’s health such as a healthy diet will affect their oral health too so we know there are clear links between levels of deprivation and levels of oral health.”
From April this year, local authorities have taken over responsibility for oral health.

Health Minister Lord Howe, said: “We know more work is needed to make sure good oral health is more consistent right across the country.

“However, we have some of the lowest decay rates in the world.”

That is commendable but all that fluoride in the toothpaste will it lead to Alzheimer's later on in life or other problems?
