4 Things You (Probably) Didn’t Know About Dental Fillings

Posted in Fillings

Are any of these facts news to you?

  1. Mercury Fillings Aren’t Poisonous

Amalgam (silver) fillings that contain mercury are not considered dangerous, so there’s no need to panic if you still have metal restorations.

The mercury in metal fillings can’t harm you, since inhaling a mercury vapor is what’s really toxic to humans. Your restorations don’t give off enough vapor to cause any toxicity. But if you’re still worried about them, your dentist can offer a safe removal method.

  1. The Oldest Known Dental Fillings Are Roughly 13,000 Years Old

In 2017, archaeologists at the University of Bologna discovered a human body that had teeth with evidence of dental work dating around 13,000 years old. Two front incisors appeared to have holes in them that were drilled with stone tools and then filled with a tar-like mixture.

  1. White Fillings “Move” with Your Teeth

Tooth-colored composite dental fillings are made from a material that contains a combination of plastic resin and glass. The result is a strong restoration that bonds with teeth and also moves with them.

Your teeth feel hard, but they actually expand and contract on a microscopic level with temperature changes. Metal fillings expand and contract too rapidly and this extreme activity can damage teeth from the inside. But white fillings move at the same rate natural tooth structure does, making them much a much more gentle and conservative restorative option.

  1. Dental Fillings Are Preventable!

Dental treatment doesn’t have to be inevitable. By cutting down on your sugar consumption, using fluoride toothpaste, and practicing good oral hygiene, you can lower your risk for needing a dental filling.

Talk with your dentist about other preventative dental treatments like sealants and fluoride varnish.
