How a baby’s first teeth develop

A newly born baby usually has no teeth visible but most have begun to develop primary or baby teeth.

These generally begin to appear about six months after birth.

Over their first few years, they will develop all 20 primary teeth and will usually have them all in place by age three.

The teething process is uncomfortable for many babies and they can become sleepless and irritable. They also might lose their appetite or drool more than usual.

If your infant has a fever or diarrhea while teething or continues to be cranky and uncomfortable, call your physician.

Sometimes when a tooth erupts, an eruption cyst may develop. The tooth will eventually rupture this as it pushes through the gums and these cysts are usually harmless and should be left alone.

If a baby has sore or tender gums when they are teething, it can help to gently rub the gum with a clean finger, a small, cool spoon or a wet gauze pad.

When this happens, your dentist or pediatrician may suggest a pacifier, teething ring or a special numbing salve for the gums.

When the teeth begin to erupt, you should brush them with a soft-bristled toothbrush and a little water to prevent tooth decay.

Toothpaste is not recommended until a child reaches age two. When a child begins using toothpaste, you need to supervise the brushing to make sure they don’t swallow it.

Regular dental checks should begin after your child’s first tooth appears or by their first birthday.

How dentistry has developed over the last 300 years

When you visit a modern dental surgery, its hard to imagine the challenges of dental treatment without all the latest technology.

Yet specialists have been taking care of peoples teeth for thousands of years.

Here are some of the key developments over the last 300 years.

1723: French surgeon Pierre Fauchard – credited as being the father of modern dentistry – publishes the first book to describe a comprehensive system for the practice of dentistry.

1760: John Baker, the earliest medically-trained dentist to practice in America, immigrates from England and sets up practice.

1790: John Greenwood adapts his mothers foot treadle spinning wheel to rotate a drill.

1790: Josiah Flagg, a prominent American dentist, constructs the first chair made specifically for dental patients.

1832: James Snell invents the first reclining dental chair.

1841: Alabama enacts the first dental practice act, regulating dentistry in the United States.

1844: Horace Wells, a Connecticut dentist, discovers that nitrous oxide can be used as an anesthesia and successfully uses it to conduct several extractions in his private practice.

1880s: The collapsible metal tube revolutionizes toothpaste manufacturing and marketing.

1890: Willoughby Miller notes the microbial basis of dental decay in a book which started a world-wide movement to promote regular toothbrushing and flossing.

1896: New Orleans dentist C. Edmond Kells takes the first dental x-ray of a living person in the U.S.

1938: The nylon toothbrush, the first made with synthetic bristles, appears on the market.

1945: The water fluoridation era begins when the cities of Newburgh, New York, and Grand Rapids, Michigan, add sodium fluoride to their public water systems.

1950s: The first fluoride toothpastes are marketed.

1960: The first commercial electric toothbrush, developed in Switzerland after World War II, is introduced in the United States. A cordless, rechargeable model follows in 1961.

Root canal treatment

Root canal therapy is an important treatment that can save a tooth with a diseased nerve and which in the past would probably have needed to be removed.

Inside each tooth is the ‘pulp’ which runs like a thread down through the root and provides nutrients and nerves to the tooth. It is the soft tissue that contains nerves, blood vessels and connective tissue.

If the pulp is diseased or injured, the pulp tissue dies.

The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp.

So, if you don’t remove it, your tooth gets infected and you could lose it.

After the dentist – or endodontist (a dentist who specializes in problems of the pulp) – removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger.

Most of the time, a root canal is a relatively simple procedure involving one to three visits with little or no discomfort.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.
