Stop grinding your teeth!

NightguardGrinding your teeth during sleep is kind of a sleep disorder. Also called bruxism, it can happen at any age.

Children sometimes do it as their teeth are changing from their primary to their permanent ones. Some people just get a wear spot, but in more serious cases, you might grind right through the enamel to the pulp.

The best prevention is a hard, plastic mouth guard created by your dentist. It will discourage grinding and protect the surface of your teeth.

Did you know your teeth are harder than bones? In fact, they are harder than steel.

Tooth enamel is unique in that it has to last our entire lifetime. The mineralisation process that produces tooth enamel creates an incredibly tough substance that is even harder than steel.

New research reveals a never-before-seen mechanism for crack deflection that helps make its exceptional resilience possible.


Can people really pick up radio waves on their braces or fillings?

Do you wear metal braces or have metal fillings in your teeth? The closer you are to a large AM transmitter, the more likely you are to hear music in your mouth.

When AM transmitters were common in big cities, it was an everyday occurrence for people living near them to hear the station on their toasters, from their light bulbs, and even from things like a metal spoon resting in a metal cup. If you’re picking up radio, your dentist can change the size of the filling or the length of wire in your braces to solve the problem.

Why are our teeth so sensitive to pain?

The legend of the tooth fairy

tooth fairyEvery single recorded human culture has some kind of tradition for the disposal of baby teeth. The story of the Tooth Fairy dates back to 13th Century Norse traditions, when it became a tradition for a ‘tooth fee’ to be given to a child when they lost their first baby tooth. Various cultures since that time advise throwing baby teeth into the sun, into fire, between the legs, onto or over the roof of the house; placing it in a mouse hole or burying or hiding it. During the 1950s and in the Disney spirit, Americans conjured up a benevolent fairy who rewards baby teeth with money.

Tiny tooth sensors to monitor your health

tooth sensorScientists from Tufts University developed tiny sensors that attach to your teeth, and monitor your diet and health in real time.

The sensor, when communicating wirelessly with a mobile device, can transmit information on glucose, alcohol and salt intake. Researchers note that future adjustments of these sensors could make them detect and record a wide range of chemicals, nutrients, and physiological states.

Your teeth are like fingerprints

Your teeth are like your fingerprints: they’re uniquely yours. Whether the 20 “baby teeth” that serve us in childhood or the 32 permanent teeth we have in our adult years, no two teeth are exactly the same shape and size. Each tooth in your mouth has its own unique profile, and teeth vary widely from person to person.

Despite their unique properties, teeth can indicate certain information about us, like our age, gender, and personality. They can indicate certain personality traits and significantly impact our overall impression of people.
