I realize this is a possible correlation but it's still a bit disturbing.
My husband had cavities about 20 years ago, has had his wisdom teeth removed, had braces in the teens, but hasn't had any cavities in the last 10 years.
I've never had a cavity or braces, but have only 1 wisdom tooth left (the other were removed but I chose to keep the last one due to it being close to a nerve).
We've been drinking fluoride-free water for 4 years.
We alternate between non-fluoride Tom's of Maine and Tropical Traditions toothpaste brushing with the Sonicare electric brush twice daily, use Tom's of Maine mouthwash twice daily, and floss daily.
Our dentist thinks are teeth are great.
How frequently do you have dental x-rays or would you recommend them?
I am a dentist with a low carb approach to the practice of dentistry. I would recommend bite wing radiographs every 18 months. Full set every 5-7 years. There are other reasons besides decay to radiograph. Restoration status and bone levels come to mind.
I take the obligation to minimise exposure to ionising radiation extremely seriously. There is no such thing as "routine" xrays in my book. In the uk, the regulations surrounding the use of ionising radiation mean that each patient's need for every single exposure to xrays should be assessed on an ad hoc basis that takes into account things like age, diet, oral hygiene, snacking habits, history of incidence of caries, history of gum disease, etc. An xray shoild be taken only if there is a proven clinical justification for doing so, ie when diagnosis can only be made or best treatment carried out with the help of a radiograph.
