From Twilight to True Blood and even Harry Potter, vampires are every where these days.
One place they’re not, however, is the dentist’s chair, according to the Chicago Dental Society, which is celebrating Halloween this year by asking local dentists to unseal the dental records of their most frightening patients.
Although they’ve been known to chip their teeth on stubborn victims—and even lose the occasional fang – vampires are largely immune to cavities, says the society.
As a CDS spokesperson, paediatric dentist Dr Mary Hayes stuck her neck out, so to speak, to answer the pointed question: Can vampires get cavities?
‘Vampires don’t get cavities because their favourite meal – blood – is not full of sugar,’ Hayes said.
‘And sugar is the main culprit in cavities.’
The mouth is home to millions of microscopic bacteria that live on the teeth, gums, lips and tongue. Some of these bacteria attach themselves to tooth enamel in plaque where they grow into large colonies.
Because bacteria use it as a food source, sugar makes the bacteria more active and the plaque thicker, making it harder for saliva, the body’s natural decay defense, to keep teeth clean.
Stubborn plaque allows bacteria to feed on sugar in the foods we eat, producing acid as a byproduct.
This acid dissolves the minerals that make tooth enamel hard, making the surface of teeth full of tiny holes. Over time, these tiny holes in the tooth enamel grow until one large hole is formed. This is a cavity.
‘There is sugar in the blood, but under most circumstances the quantity is very small,’ Dr Hayes explained.
‘There isn’t enough of it available to cause decay. The bacteria in the mouth like sugar to be the main part of the diet, and sugar is incidental in the composition of blood.’
While drinking blood typically won’t cause cavities, it could have cosmetic side effects. Blood contains iron, and people who have extra iron in their diet can get a grayish stains on their teeth. While these stains are superficial, they nonetheless can gray out pearly whites.
While humans and vampires may have different oral hygiene issues, there is at least one thing they can agree on: No one likes the smell of garlic on their breath!
If you’ve consumed too much of this pungent vampire deterrent, the best thing to do is brush your tongue.
