Those with dental insurance could be less likely to need to make a claim if they do not rinse their teeth after brushing.
An expert has advised that, contrary to what is widely believed by the public, teeth are better protected if people do not rinse them once they have been brushed.
Dr Phil Stemmer, from The Fresh Breath Centre in London, told the Daily Mail that this is because rinsing washes away the protective layer of fluoride left behind by the toothpaste .
"I try to avoid drinking any fluids for at least half an hour after brushing - it's a strange sensation at first, but you quickly get used to it," he said.
He also recommends not brushing teeth directly after eating as this could cause damage.
"Wait at least half an hour because the food acids and sugars temporarily weaken the protective enamel on the teeth. If you clean your teeth too soon, you are actually brushing away at the enamel before it hardens again," the expert said.
A study by the Office for National Statistics published last year revealed that two in five people do not get their teeth checked regularly by a dentist .
