WHAT IS AS BRITTLE AS GLASS and at the same time, the hardest substance in your body?

Tough Stuff

Your tooth enamel! Each time you bite down it handles the equivalent of 72 kilos of pressure, time after time after time. Think about how often you bite down during your lifetime. It’s crazy!

Enamel is the hard outer layer of your teeth, built to protect the softer dentine layer, and your super-sensitive pulp.

It’s Amazing How Such A Brittle Substance Handles The Pressure

It’s an engineering marvel. Enamel is actually made up of a dense forest of long rods. These rods start crisscrossing each other as they go deeper into the tooth, diffusing the pressure. It’s like sprawling your body out flat to crawl over an ice-covered pond, spreading the pressure over a wider area.

Mother Nature’s Pattern For Strength

This same concept actually inspired a group of scientists to create glass that is 200 times stronger than normal! Read about it in the article, How to Toughen Glass by Cracking It: A Lesson From Teeth and Shells.

Enamel Is Built To Deal With Pressure… But Not Erosion

As strong as your enamel is, it doesn’t deal as well with acid and bacteria. It needs our help for that.

4 ways your enamel CAN get worn down:

  1. Acidic breakdown (usually from acidic drinks like fizzy drinks, fruit juices, and sports drinks).
  2. Abrasion from rough brushing and tooth-whitening toothpastes.
  3. Bad habits like tooth-grinding.
  4. High sugar-and-starch diets, which create acid byproducts.

Your Enamel Is Finite So Treat It Well

As amazing as your enamel is, it’s one of the only parts of your body unable to regenerate itself because it’s one of the only parts of your body not comprised of living cells. So protect your enamel by brushing regularly with fluoride toothpaste, flossing, and keeping your regularly scheduled checkups.

COVID-19 UPDATE - November 2020

Despite the latest lockdown we are still open.

Due to social distancing requirements and enhanced infection control procedures we are having to run the practice at a reduced capacity then we would do normally.

Opening hours are 9.00am to 5.00pm Mon-Thurs and 9.00 to 4.00pm Fridays.

Whilst we are doing check ups and routine dentistry we have long waiting times for appointments.

We also run a telephone emergency service during normal working hours. Out of hours advice is available via NHS Direct on 111.

Due to our reduced capacity we are unable to take on new NHS patients but can provide emergency advice and care if appropriate.
