The History of Dental Advances


Many of the most common dental tools were used as early as the Stone Age. Thankfully, technology and continuing education have made going to the dentist a much more pleasant – and painless – experience. Here is a look at the history of dentistry's most common tools, and how they came to be vital components of our oral health care needs.

Where did toothbrushes and toothpaste come from?

The first toothbrushes were small sticks or twigs mashed at one end to create a broader cleaning surface. The Chinese lay claim to the first bristle toothbrush. Europe adopted the bristle brush in the 17th century, and many dentists practicing in colonial America advised their patients to use the brush. The first electric toothbrush was marketed in 1880, though the Swiss developed the first effective electric toothbrush just after World War II. It was introduced in the United States around 1960. A year later, the first cordless model was developed and proved to be popular with both consumers and dentists.

Toothpaste also saw its earliest form in ancient civilizations. Early toothpaste ingredients included powdered fruit, burnt or ground shells, talc, honey and dried flowers. Less agreeable ingredients included mice, rabbit heads, lizard livers and urine. Despite the decidedly non-minty flavor of early toothpaste, various recipes continued to appear throughout ancient history and well into the Middle Ages. Unfortunately, many of these toothpastes contained corrosive elements that dissolved tooth enamel.

Toothpaste as we know it emerged in the 1800s, with ingredients that included soap and chalk. In 1892, the first collapsible tube was marketed and reigned supreme until 1984, when the pump dispenser was introduced. In 1956, Proctor & Gamble introduced Crest brand toothpaste with fluoride.

When was drinking water fluoridated?

In 1945, Grand Rapids, Michigan introduced fluoride into their public water systems to help fight tooth decay among residents. At the same time, a group of Wisconsin-based dentists succeeded in getting the state's water system fluoridated. After substantial testing showed that fluoride reduced the incidence of cavities by as much as two-thirds, in 1951 the U.S. Public Health Service urged the entire country to fluoridate public drinking water.

The idea for water fluoridation resulted from an observation made by a dentist from Colorado Springs, Colorado, in the early 1900s. Frederick McKay noticed that locals had brown stains on their teeth. He called the staining "enamel mottling" and attributed it to drinking water with high fluoride content. He reported that the locals had a reduced incidence of tooth decay. In 1940, another dentist revealed that one part fluoride per one million parts water was the ideal ratio for reducing decay while preventing staining. Soon after, fluoride gained acceptance, and today more than 60 percent of Americans have fluoridated water.

What's the history behind false teeth?

Thanks to modern technology, today's false teeth are largely indistinguishable from real teeth. This wasn't always the case. Perhaps the most famous false-toothed American was the first president, George Washington. Popular history gave Washington wooden teeth, though this was not the case. In fact, wooden teeth are impossible; the corrosive effects of saliva would have turned them into mushy pulp before long. As a matter of fact, the first president's false teeth came from a variety of sources, including teeth extracted from human and animal corpses.

Despite this seemingly gruesome practice, dental practitioners preceding Washington's time attempted aesthetic restorations. Ancient civilizations used ivory and bone to create new teeth. Unfortunately, this craft was lost until the mid-1800s. Rotten or damaged teeth were simply extracted, and gaps became a way of life. When false teeth were warranted, threads of silk or tightly coiled springs were used to hold the new teeth in place; it wasn't much of an anchor, and teeth had to be removed before eating, lest they literally spring from the wearer's mouth. Additionally, genuine teeth extracted from the living and the dead and set in another's mouth soon rotted. Those who could afford it opted to have new teeth fashioned from ivory, gold or silver.

It wasn't until 1774 that two Frenchmen, a pharmacist and a dentist, designed a set of porcelain teeth. Steady improvements were made on the teeth, most notably in 1808 when an Italian dentist invented a single porcelain tooth imbedded with a platinum pin. These teeth came to America in 1822, and for the rest of the century dentists and technicians tinkered with the design, fit and feel of the teeth. A breakthrough occurred in 1839 with the discovery of vulcanized rubber, which was used to hold false teeth. Today's dentures are made of either plastic or ceramic.

How long have we had anesthesia?

Though dentistry has been around in one form or another since the days of primitive humans, painless extraction wasn't available until the 1830s. In the beginning, teeth were removed with a well-placed chisel and a hard swing of a mallet. Thousands of years later, during peaks of the great Greek and Roman civilizations, the chisel-and-mallet method was abandoned in favor of forceps.

In the 1790s, a British chemist began to experiment with the use of nitrous oxide as a pain-inhibitor and noted its most famous side effect, laughing. He coined the anesthetic's popular nickname, "laughing gas." During the next 50 years, the gas became very popular. In 1863 the gas was combined with oxygen, becoming a staple of surgical procedures.

Soon after the adoption of nitrous oxide, local anesthetics were developed. Just prior to the 1900s, cocaine was used, but once its addictive qualities were identified, the search began for a suitable alternative. Many of the alternatives were forms of synthetic cocaine, but none were successful until 1905 when a German chemist discovered procaine, which he named Novocain. The anesthetic proved extremely popular with dental professionals, as well as a public relieved at the sound of "painless dentistry."

Good Oral Health Is Essential During pregnancy


It's no secret that pregnancy is an important time in a woman's life. While women often hear about how pregnancy causes physical changes that affect their hormone or appetite levels, these changes can have a great effect on their oral health as well. Despite the fact that good oral health is essential for the overall health of both mother and child, only 22 to 34 percent of women in the United States visit a dentist during pregnancy. In fact, dental care during pregnancy is not only safe and effective, it's essential for combating the adverse effects of oral disease, according to an article published in the May/June 2010 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD). Dentists have the ability to maintain the oral health of expectant mothers by treating the dental findings that are common during pregnancy. 
"Hormonal changes during pregnancy can result in several changes in the mouth," says Homa Amini, DDS, co-author of the article. "Reports show that the most common oral disease is gingivitis, which has been reported in 30 to 100 percent of pregnancies."
Gingivitis, a buildup of plaque that causes inflammation of the gums, should be treated with a professional cleaning and proper toothbrushing and flossing. If left untreated, gingivitis can lead to periodontitis, a more serious form of gum disease. "Patients tend to delay the treatment of oral disease due to concerns for fetal safety; however, routine dental treatment can be performed safely at any time during pregnancy," says Dr. Amini. What's more, untreated dental disease can lead to pain, infections and unnecessary exposure to medications, any of which could harm the developing fetus. Poor oral health also can affect the nutritional intake of expectant mothers, which is essential for fetal growth and survival.
The hormonal fluctuations that result from pregnancy can produce benign pregnancy tumors in the mouth. These tumors usually appear after the first trimester and typically go away after delivery; however, surgical removal may be required when these tumors bleed, interfere with eating or do not resolve after delivery.
In addition to examining for oral disease, dentists may notice dental erosion—the chemical or mechanochemical destruction of tooth material—in pregnant women, due to increased acid in the mouth following morning sickness.
"To neutralize acid after vomiting, pregnant women should rinse the mouth with a mixture of a teaspoon of baking soda dissolved in a cup of water," says Patricia Meredith, DDS, FAGD, spokesperson for the AGD. "The teeth should be brushed only after the mouth has been rinsed and the acid has been neutralized to prevent further damage to the enamel."
Oral health assessment and treatment should be an essential part of prenatal care, as these steps allow the patient to receive ongoing advice concerning proper oral hygiene and infant oral health care.

When Should My Child See The Dentist (For The First Time)?


Your child's first visit to the dentist should happen before his or her first birthday. The general rule is six months after eruption of the first tooth. Taking your child to the dentist at a young age is the best way to prevent problems such as tooth decay, and can help parents learn how to clean their child's teeth and identify his or her fluoride needs. After all, decay can occur as soon as teeth appear. Bringing your child to the dentist early often leads to a lifetime of good oral care habits and acclimates your child to the dental office, thereby reducing anxiety and fear, which will make for plenty of stress-free visits in the future.

How do I prepare my child and myself for the visit?

Before the visit, ask the dentist about the procedures of the first appointment so there are no surprises. Plan a course of action for either reaction your child may exhibit – cooperative or non- cooperative. Very young children may be fussy and not sit still. Talk to your child about what to expect, and build excitement as well as understanding about the upcoming visit. Bring with you to the appointment any records of your child's complete medical history.

What will happen on the first visit?

Many first visits are nothing more than introductory icebreakers to acquaint your child with the dentist and the practice. If your child is frightened, uncomfortable or non-cooperative, a rescheduling may be necessary. Patience and calm on the part of the parent and reassuring communication with your child are very important in these instances. Short, successive visits are meant to build the child's trust in the dentist and the dental office, and can prove invaluable if your child needs to be treated later for any dental problem.


Child appointments should always be scheduled earlier in the day, when your child is alert and fresh. For children under 36 months, the parent may need to sit in the dental chair and hold the child during the examination. Or, parents may be asked to wait in the reception area so a relationship can be built between your child and the dentist.

If the child is compliant, the first session often lasts between 15 and 30 minutes and may include the following, depending on age:

  • A gentle but thorough examination of the teeth, jaw, bite, gums and oral tissues to monitor growth and development and observe any problem areas
  • If indicated, a gentle cleaning, which includes polishing teeth and removing any plaque, tartar buildup or stains
  • X-rays
  • A demonstration on proper home cleaning
  • Assessment of the need for fluoride
The dentist should be able to answer any questions you have and try to make you and your child feel comfortable throughout the visit. The entire dental team should provide a relaxed, non-threatening environment for your child.

When should the next visit be? 

Children, like adults, should see the dentist every six months. Some dentists may schedule interim visits for every three months when the child is very young to build up a comfort and confidence level or to treat a developing problem.

How do I find a good dentist for my child?

Many general dentists treat children. If yours does not, ask for a referral to a good dentist in your area. A word-of-mouth recommendation from a friend or family member can also yield the name of a quality dentist.

How can I protect my child's oral health at home?


Parents typically provide oral hygiene care until the child is old enough to take personal responsibility for the daily dental health routine of brushing and flossing. A proper regimen of preventive home care is important from the day your child is born.

  • Clean your infant's gums with a clean, damp cloth after each feeding.
  • As soon as the first teeth come in, begin brushing them with a small, soft-bristled toothbrush andwater.  If you are considering using toothpaste before your child's second birthday, ask your dentist first.
  • To avoid baby bottle tooth decay and teeth misalignment due to sucking, try to wean your child off of the breast and bottle by one year of age, and monitor excessive sucking of pacifiers, fingers and thumbs. Never give your child a bottle of milk, juice or sweetened liquid as a pacifier at naptime or bedtime.
  • Help a young child brush at night, the most important time to brush, due to lower salivary flow and higher susceptibility to cavities. Perhaps let the child brush their teeth first to build self-confidence, then the parent can follow up to ensure that all plaque is removed. Usually by age 5 or so, the child can learn to brush his or her own teeth with proper parental instruction.
  • The best way to teach a child how to brush is to lead by good example. Allowing your child to watch you brush your teeth teaches the importance of good oral hygiene.

Cleanings & Prevention


A preventive program is a cooperative effort by the patient, dentist, and dental staff to preserve the natural dentition and supporting structures by preventing the onset, progress, and recurrence of dental diseases and conditions.


Preventing dental disease starts at home with good oral hygiene and a balanced diet.  It is continued in the dental office by the efforts of your dentist and dental hygienist to promote, restore, and maintain your oral health.

Prevention also includes regular dental exams, cleanings, and x-rays. Sealants and fluoride are also great preventive treatments that help protect the teeth.

Prevention helps avoid serious and costly dental problems and is the key to having a healthy, confident, beautiful smile.

Dental Crowns



A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size.  A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.

Although there are several types of crowns, porcelain (tooth colored crown) are the most popular, because they resemble your natural teeth.  They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced.  Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.

Reasons for crowns:
  • Broken or fractured teeth.
  • Cosmetic enhancement.
  • Decayed teeth.
  • Fractured fillings.
  • Large fillings.
  • Tooth has a root canal.
What does getting a crown involve?
Although many porcelain crowns can be made using our CEREC technology, special situations often necessitate a traditional crown procedure requiring two appointments.  Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown.  A mold will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.

While the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown.  Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.

You will be given care instructions and encouraged to have regular dental visits to check your new crown.

Tooth Discoloration

What Is It?


Your teeth can become discolored by stains on the surface or by changes in the tooth material. Dentists divide discoloration into three main categories:
  • Extrinsic discoloration — This occurs when the outer layer of the tooth (the enamel) is stained by coffee, wine, cola or other drinks or foods. Smoking also causes extrinsic stains.
  • Intrinsic discoloration — This is when the inner structure of the tooth (the dentin) darkens or gets a yellow tint. Causes include excessive exposure to fluoride during early childhood, the maternal use of tetracycline antibiotics during the second half of pregnancy and the use of tetracycline antibiotics in children 8 years old or younger.
  • Age-related discoloration — This is a combination of extrinsic and intrinsic factors. In addition to stains caused by foods or smoking, the dentin naturally yellows over time. The enamel that covers the teeth gets thinner with age, which allows the dentin to show through. Chips or other injuries to a tooth can also cause discoloration, especially when the pulp has been damaged.
In rare cases, children with a condition called dentinogenesis imperfecta are born with gray, amber or purple discolorations.

Symptoms

Symptoms include stains on the enamel or a yellow tint in the dentin.

Diagnosis

No special tests are needed. A dentist can diagnose tooth discoloration by looking at the teeth.

Expected Duration

Some tooth discoloration can be removed with professional cleaning, but many stains are permanent unless the teeth are treated (whitened) with a bleaching gel.

Prevention

Brushing your teeth after every meal will help to prevent some stains. Dentists recommend that you rinse your mouth with water after having wine, coffee or other drinks or foods that can stain your teeth. Regular cleanings by a dental hygienist also will help to prevent surface stains.
Intrinsic stains that are caused by damage to a nerve or blood vessel in the inner part (the pulp) of a tooth sometimes can be prevented by having root canal treatment, which removes organic material before it has a chance to decay and darken. However, teeth that undergo root canal treatment may darken anyway. To prevent intrinsic stains in children, avoid water that contains a high fluoride concentration. You can check the concentration of fluoride in your drinking water supply by calling the public health department. Then consult your dentist.

Treatment

Discoloration often can be removed by applying a bleaching agent to the enamel of the teeth. With a technique called "power bleaching," the dentist applies a light-activated bleaching gel that causes the teeth to get significantly whiter in about 30 to 45 minutes. Several follow-up treatments may be needed.
It's also possible to remove discoloration with an at-home bleaching gel and a mouth guard given to you by your dentist. The bleaching gels designed for use at home aren't as strong as those applied by your dentist, so the process takes longer — usually two to four weeks. Whitening toothpastes may remove minor stains, but they aren't very effective in most cases.
If you've had a root canal and the tooth has darkened, your dentist may apply a bleaching material to the inside of the tooth.
When a tooth has been chipped or badly damaged or when stains don't respond to bleaching, your dentist may recommend covering the discolored areas. This can be done with a composite bonding material that's color-matched to the surrounding tooth. Another option is to get veneers, which are thin shells of ceramic that cover the outer surfaces of the teeth.

When To Call a Professional

Tooth discoloration is mainly a cosmetic problem. Call a dentist if you're unhappy with the appearance of your teeth. Any change in a child's normal tooth color should be evaluated by a dentist.

Developing Teeth: Moving From Primary To Permanent

Because there are more permanent teeth than primary teeth, the permanent premolars come in behind the primary molars. Permanent molars emerge into an open space. The jaw lengthens as a child grows to create space for these permanent molars.
It takes about six years, between the ages of six and 12, for children to lose their primary (deciduous) teeth and gain their permanent teeth. This is called the period of "mixed dentition," because for much of the time, children will have both primary and permanent teeth. Teeth form under the gum before they erupt (emerge through the gum). The crown, or visible part of the tooth, forms before the roots do. Before the roots form, the developing tooth is called a "tooth bud."
Eventually, the 20 primary teeth are replaced by 32 permanent teeth. The primary molars are replaced by permanent premolars (also called bicuspids) and the permanent molars come in behind the primary teeth. Most often, the first teeth to emerge are the lower two front teeth (incisors) and the upper and lower first molars, the molars closest to the front of the mouth. They are followed by the upper two front teeth. The order that teeth emerge can vary. Parents should be more concerned about symmetry (the same teeth coming in at the same time on both sides) than the time teeth emerge.
