Can you brush your teeth too hard
Yes, brushing too hard can ultimately lead to decay and sensitive teeth.
Ever since we were children, we've been told that brushing our teeth properly is important to protect against cavities.
So plenty of us approach the task with the enthusiasm of an army cadet trying to clean his dirty boots – we figure the harder we scrub, the better the result will be.
But brushing your teeth requires a more delicate approach, says Dr Peter Alldritt, chairman of the Australian Dental Association's oral health committee.
"People can literally kill their teeth with kindness," says Alldritt.
