At what age do permanent teeth start to fall out?!

Hello
if you brush 2 times a day and floss once a day and use a good quality toothpaste and have a healthy diet, your teeth will last until you die. Avoid sugar and starchy foods and eat tooth kind foods such as yogurts, milk, sprouts, fresh veggies and fruits( apples and pears and non citrus fruits). Cheese is also good and protein( chicken and fish).Avoid fizzy drinks and too much acidic food and drink. Also visit your dentist every 6 months and you will still have all your own teeth at your own funeral.

My nanny is 91 and has false teeth as she eats sweets like no tomorrow. I do not ever want false teeth, hence why I look after mine ;-)

myself as I love looking after my teeth
