What did the first dentures look like?

December 16th, 2015

Remember hearing about George Washington and his wooden choppers? Not his tools for cutting down cherry trees, but his false teeth.

Actually, George’s teeth were made of ivory but were so stained that they appeared to be made out of wood. You might think those were the earliest dentures. In fact, the history of false teeth goes back centuries before President Washington.

Ancient Times

The earliest known dentures consisted of human or animal teeth tied together with wires. Examples of such dentures have been found in Egyptian and Mexican archeological sites. Other ancient peoples use carved stones and shells to replace lost teeth. These early dentures were probably made for cosmetic purposes. The materials they used were not likely to stand up to the pressure placed on teeth during eating.

The earliest surviving set of complete dentures were actually made out of wood (sorry, George). They were found in Japan and date back to the 16th century.

Human and animal teeth continued to be popular materials for dentures until the 20th century in some parts of the world. But the difficulty obtaining healthy teeth (and the risk of disease from unhealthy teeth) led dentists to search for other substances.

Modern Era

In the 18th century, dentists began using porcelain, ivory, gold, silver and even rubber as tooth substitutes. Dentures made with these substances could be used in eating. They were often ill-fitting, however, which may explain why George Washington looks puffy and glum in many portraits.

Porcelain and metals were the most popular denture materials until about 1950, when plastics and resins were developed. Tough and durable, these materials make up most of the dentures Dr. Keldsen and our team use today.

Still, what goes around comes around. Researchers at the University of Texas are looking at using human teeth for dentures once again. Only in this case, the researchers hope to use biotechnology to spur the growth of new sets of teeth to replace those lost over a lifetime.

Good Teeth Lead to Sporting Success

December 9th, 2015

You already know that taking care of your teeth can help prevent tooth decay and the need for extensive work such as root canals or implants, which can be inconvenient and expensive. But the benefits of good teeth can go far beyond having an attractive smile and being able to crunch carrots and chew meat.

The American Dental Association explains that healthy teeth are linked to a lower risk for heart disease and diabetes. Furthermore, recent research published in the British Journal of Sports Medicine states that good teeth can improve athletic performance among elite athletes.

Researchers examined the oral health of nearly 300 athletes in 25 sports at the 2012 Olympics in London. They looked for conditions such as dental caries, gingivitis, dental erosion, and periodontal disease, and asked about recent visits to a dentist.

Study investigators also asked athletes whether their oral health interfered with quality of life or athletic training and performance. The study concluded that poor oral health and fewer dental visits led to interference with preparation for competition.

This can happen for a few reasons. Tooth pain can disrupt sleep, which leads to slower reaction times. Oral health conditions can indicate chronic inflammation in the body, which means suboptimal performances on an elite level. Tooth pain can interfere with focus during training and competition.

Unfortunately, merely taking good care of your teeth won’t turn you into an Olympic gold medalist. However, the benefits can still be worthwhile. Even if healthy teeth provide little if any detectable gain in your athletic abilities, the potential benefits of maintaining a healthy mouth clearly go far beyond an attractive smile.

Practicing good oral hygiene and seeing Dr. Keldsen regularly can promote your physical health, and maybe – just maybe – you will start to achieve an advantage over your weekend athletic opponents.

How long do dental implants last?

December 2nd, 2015

The average dental implant can last a lifetime if taken care of properly. In fact, studies have shown that the success rate of implants after ten years is about 90%! Of course, Dr. Keldsen and our team know that the better you care for your implant, the longer it will last.

There are a few factors that must be taken into consideration, when you are considering dental implants. These factors all play a role in how long your dental implants will last.

  • Bone Structure – You must have enough bone in your mouth for the implants to be inserted. Over time, the bone can wear down and become too thin or to short. In cases, where you may have just enough bone for the implants, over the years, the bone will continue to become smaller and thinner and the implants will not last nearly as long as the suggested minimum of ten years.
  • Healthy Gums – Diseased gums will not support dental implants for very long. It is important to maintain regular dental visits to maintain your healthy gums.
  • Good Oral Hygiene – Just because your implants are not your “real” teeth, doesn’t mean you have to take care of them. That means brushing, flossing, and regular professional cleanings.

Bone structure, healthy gums, and good oral hygiene all play a crucial role in the length of time your dental implants will last. Whether you have full dental implants, partial implants, or a single tooth implant. The bottom line is you have to take care of them if you want them to last as long as possible.

Is gingivitis preventable?

November 25th, 2015

The earliest sign of gum disease is called gingivitis (sometimes called periodontal disease), and is an inflammation of the gums. If left untreated, gingivitis can lead to gum tissue loss, loss of bone that supports the teeth, and eventually tooth loss. The good news is that gingivitis is easily treatable at Keldsen Family Dental Care. Better yet, gingivitis is nearly 100 percent preventable.

Gingivitis is usually caused when plaque and bacteria accumulate on the gums, generally due to poor oral hygiene. A patient with gingivitis will have red and puffy gums that will likely bleed when he or she brushes or flosses.

It is almost entirely within our patients’ power to prevent gingivitis by brushing and flossing on a daily basis. In addition to good oral health habits, regular visits to see Dr. Keldsen will also help with early detection. We can often detect minor inflammation and other signs of gingivitis before it causes any discomfort or issues.

If left untreated, gingivitis will eventually progress to periodontitis, a breakdown of the tissue and bone that support the teeth. Smokers, women who are pregnant or menopausal, people with heart disease, diabetes, epilepsy or HIV infection, and people who suffer from poor nutrition are more likely to have gum disease.
