First in Dental History – Back to School!

/in /by

With the school year fast approaching, let’s take a minute to learn about where modern day dentistry first started:

Ancient Dentistry

5000 BC – “Tooth worms” is described as the cause of decay in a Sumerian text.

166-201 AD – The Etruscans (ancient French and Italians) practice dental prosthetics such as gold crowns and fixed bridgework.

The Middle-Ages

700 AD – An ancient Chinese medical text mentions the use of an amalgam filling material referred to as “silver paste”.

1210 AD – The “Guild of Barbers” is established. These barbers could perform bloodletting, teeth pulling, and cupping therapy-in addition to cutting your hair and shaving facial hair. (YIKES)

18th Century

1723 – Pierre Fauchard (“The Father of Modern Dentistry”) publishes The Surgeon Dentist, A Treatise on Teeth (Le Chirurgien Dentiste). The book was the first to describe a comprehensive system for the practice of dentistry including basic oral anatomy and function, operative and restorative techniques, and denture construction.

1768-1770 – In the first known case of post-mortem dental forensics, Paul Revere identifies his friend’s body from a bridge he had constructed for him.

1790 – The first “dental drill” operated by foot pedal is created by John Greenwood out of his mother’s foot treadle spinning wheel.

19th Century

1825 – Commercially manufactured porcelain teeth hit the market

1864 – The rubber dam is invented, a device still used today to isolate the tooth from the oral cavity during procedures.

1866 – Dr. Lucy Beaman Hobbs becomes the first woman to earn a dental degree.

1869 – Dr. Robert Tanner Freeman becomes the first African-American to earn a dental degree.

1880 – Toothpaste is revolutionized with the invention of the collapsible metal tube. Previously, toothpaste was sold in liquid or powder form (made by dentists) and packaged in bottles, pots, or paper boxes.

1896 – Dr. C. Edmond Kells takes the first dental x-ray of a living person in the U.S.

20th Century

1905 – A German chemist formulates a local anesthetic and markets it under the name “novocaine”

1937 – Alvin Strock inserts the first Vitallium (biocompatible implant metal) dental screw implant.

1950 – The first fluoride toothpastes are marketed and become industry standard within 20 years.

1960 – Lasers are developed and approved for soft-tissue work.

1989 – The first commercial home tooth bleaching product is marketed.

Many, many more developments in materials and procedures have occurred since then and come to form dentistry as we know it today. Stop in to our friendly Coquitlam office and book your next cleaning and check up with Dr. Shahriary! Call Today (604) 936-1263

 

Whitening – What are the options?

/in /by

There are many different teeth bleaching options available over the counter and in office, but which is best for you?

 

Whitening Strips

Over-the-counter whitening strips like Crest White Strips are a popular option due to their low cost. The strips are sold as a thin, flexible membrane coated with bleaching material that conforms to the shape of your teeth.

Pros:

  • They can be worn comfortably at home or on the go, making them a convenient option.
  • Cost effective

Cons:

  • Not suitable for crooked teeth
  • Often misses the areas between the teeth
  • Saliva can get under the membrane and dilute the bleach
  • Not ideal for a “wide smile” as they are “one size fits all”
  • The strips are prone to slip and slide out of place
  • Low concentration of bleach

Brush-On Whiteners

Often sold in pen style applicators with foam or brush tip applicators, brush-on whiteners are the least expensive option. They are most effective when applied directly after a meal or beverage with high colour content (beets, red wine, etc…). While this product claims to whiten your teeth, they act as more of an “antidote” to new stains.

Pros:

  • Inexpensive
  • Convenient

Cons:

  • Does not show meaningful results as a “whitening” tool

Custom Bleach Trays (Opalescense)

Unlike whitening strips, custom bleach trays are made specifically for your teeth and can not be shared with others. First an impression is take of your mouth and model is made of your teeth. Then a tray is formed around the model using a thin, flexible plastic material. The dental office then provides you with concentrated bleaching gel in syringe applicators and instructions on how to use the bleach at home.

Pros:

  • Extremely effective whitening
  • Ideal for people with crooked teeth as the bleach reaches all surfaces of the teeth
  • Long term results, often lasting 6 months or more
  • Concentrated bleach gel often gives drastic results within 2 weeks
  • Shaped to prevent bleach from coming into contact with your gums (when used correctly)

Cons:

  • Can cause sensitivity
  • Significantly higher cost than over-the-counter bleaching solutions due to the medical grade whitening gels

In-Office Whitening (Opalescence Boost)

In-office whitening is performed by your Dentist or Dental Hygienist. A cheek retractor is placed in the mouth to pull your lips and cheeks away from your teeth. Then a protective gel is placed on to your gum line and light-cured to guard your gums from the potent bleaching materials. A layer of whitening gel is painted on to your teeth and left for 20 minutes, then removed and applied again for an additional 20 minutes. Multiple visits may be required for desired results.

Pros:

  • Highest concentration bleach, causing drastic shade changes
  • Quick, sometimes immediate results

Cons:

  • Can cause sensitivity due to high concentration bleach
  • May require multiple appointments for desired results
  • The least cost effective option
  • Some people find the cheek retractors uncomfortable as they stay in the mouth for almost an hour

Dental Sealants – What are they and why is my Dentist recommending them?

/in /by

Dental sealants are a great way to prevent decay from forming in the grooves of our teeth. Teeth are formed with grooves and pits in them that can trap food and the longer these food particles stay trapped in these areas the more likely they are to develop decay.

While most of us are aware of the traditional way of cleaning our teeth ie: brushing, flossing, and mouthwash; manual plaque removal does not always work when your teeth have deep fissures in their surfaces. When this happens your Dentist may recommend dental sealants to help with the deeper, uncleanable grooves. Dentists recommend dental sealants most often when children’s permanent premolars and molars are erupting into the mouth.

Sealants require no freezing and are a thin, transparent resin painted onto the biting surface of the tooth and light cured to harden. The resin fills in the narrow grooves, decreasing your risk of decay. Sealants generally last 5-8 years before needing to be reapplied.

Dr. Shahriary can tell you at your next visit if any of your teeth should be sealed and protected, because not all teeth need sealants.

Remember to maintain regular visits to the dentist for dental examinations and professional cleanings.
