New Toothbrush

It has been a long time since toothbrushes have changed. This interesting personally tailored brush, called the Blizzident is 3D printed to order and claims to clean your teeth in six seconds. The Company does have FDA approval for materials and production, but toothbrushes are FDA Class 1 devices and therefore generally do not need an FDA approval.

It looks almost like a set of dentures and has 400 bristles in a mold of a person's mouth. By biting down on the mouthpiece and grinding on it, the 45-degree angled bristles are supposed to clean your teeth in six seconds.

There are also inter-dental bristles that get between teeth. The Blizzident comes with slits where dental floss can be inserted to clean between teeth and the handle has a container for the dental floss. In the middle there is also a tongue scraper and brush so you clean your tongue at the same time.

The toothbrush is tailored to a person's mouth through either a dental impression or a dental scan performed by a dentist. The 3D scan can be uploaded to Blizzident's site, where it is used to make the toothbrush with a 3D printer. The first Blizzident brush costs $299 and recommended annual replacement brushes sell for $159. The company also offers to refurbish a brush by replacing the bristles for $89. Here is a LINK to the site. Wow, personally tailored low tech and high tech in one package.

Origin of Breath Mints

Bad breath in ancient Egypt often was a symptom of poor dental health. Seems the stones they used to grind flour for bread contributed a lot of sand and grit to their diet, which wore down tooth enamel to expose the pulp of the tooth and making it vulnerable to infection.

The Egyptians didn't have dentists to fix their deteriorating teeth and gums. Instead, they simply suffered, and scientists who examined mummies have found severely worn teeth and evidence of abscesses, even in youthful Egyptians. To cope with the unpleasant odors from their rotting mouths, Egyptians invented the first mints, which were a combination of frankincense, myrrh and cinnamon boiled with honey and shaped into pellets.

Archaeologists also found toothpicks buried alongside mummies, apparently placed there so that they could clean food debris from between their teeth in the afterlife. Along with the Babylonians, they're also credited with inventing the first toothbrushes, which were frayed ends of wooden twigs.

The Egyptians also contributed toothpaste. Early ingredients included the powder of ox hooves, ashes, burnt eggshells and pumice. They also found what appears to be a more advanced toothpaste recipe and how-to-brush guide written on papyrus that dates back to the Roman occupation in the fourth century A.D. It explains how to mix precise amounts of rock salt, mint, dried iris flower, and grains of pepper, to form a "powder for white and perfect teeth"
