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 16^th century.

Human and animal teeth continued to be popular materials for dentures until the 20^th 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 18^th 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. Gregory Weaver 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.

Does the thought of getting a dental implant put knots in your stomach? There are many people who don't enjoy getting dental work done and there is a myriad of reasons why. For whatever reason you aren't at your best when you arrive at our Raleigh, NC office, we'd like to offer some tips that can help put you at ease for your implant procedure.

Sedation

For lengthy visits like an implant procedure, sedation dentistry may be an option for you. With sedation dentistry you are given sedation medication, usually orally with a pill or intravenously, which allows you to drift through the entire procedure without any memory of it afterward. If you decide on oral sedation, typically you take the medication about an hour before your procedure starts.

To avoid any complications, a complete medical background check is made along with a record of any allergies before any sedation is administered. Your vital signs are also monitored throughout the entire procedure.

If you decide sedation is not the right option for you, there are other techniques that you can benefit from. Some of these include:

• Communication: This may seem obvious, but communicating any fears or anxiety you may have about your procedure with us is extremely helpful. Not only does this build a relationship of trust but it allows us to try and alleviate your anxiety as much as we can.
• Herbal teas: Drink some herbal tea (like chamomile or lemon balm) before you visit the office. Many patients find this is a great help in relieving anxiety and putting them sufficiently at ease.
• Relaxing music: Bring a pair of headphones along and listen to your favorite music during treatment (preferably something low-key). Or why not catch up on your reading when you visit us — some patients like to listen to audiobooks too!
• Meditate or practice deep breathing: Meditation and deep breathing are good to practice in general, since they relax both the body and mind. They can be effective in the case of anxiety, too!

Since dental implants first started being implemented in the 1980s, they have been primarily made of titanium. Recent advances in implant technology have allowed dental implant manufacturers to shift from all-metal implants, to part-metal and part-ceramic implants, to the newer all-ceramic or zirconia implants.

Zirconia implants are made of high-impact resistant ceramic called tetragonal zirconia polycrystal (ZrO2+Y2O3). They remedy many of the issues and complaints doctors and patients have with traditional metal implants and have several advantages—let’s take a look at some of them.

Advantages of Zirconia Implants

• Do not cause allergic reactions – Although titanium is considered non-toxic, some people still have allergic reactions to titanium. Zirconia implants are inert, non-corrosive, and hypoallergenic.
• Have been used for decades in medical applications – Millions of patients have had zirconia used safely and effectively as the base material for their hip replacements. The zirconia used for medical applications also undergoes strict radiation monitoring to ensure its safety for use within the body.
• They are incredibly strong – Unlike titanium implants, zirconia offers a much higher degree of resistance to scratching, corrosion, and fracture. The aerospace industry even uses zirconia (ZrO2) due to its high resistance to heat and fracture. This all means a safer and more aesthetically pleasing result for the patient.
• One-piece design is more hygienic – Zirconia implants are a one-piece design, meaning there is nowhere for bacteria to build up or liquids to penetrate like with titanium implants. They are highly biocompatible (how a material reacts with the human body) which leads to healthier gums and no risk of corrosion.
• Implant margin is at gum not bone level – With titanium implants the margin (or gap between the implant and the tooth) is at bone level, which can lead to bacterial buildup since you can’t brush there. The zirconia implant margin, which is at gum level, allows you to brush and clean your implant and restoration regularly.

If you are in need of a restorative dental implant, it would be wise to consider zirconia due to its many advantages. It might not work in every situation, but feel free to discuss your options with Dr. Gregory Weaver or one of our Raleigh, NC staff members.

Have you ever noticed your attention being instantly drawn to peoples’ teeth when they smile at you? Some people have dull and yellowing teeth, while others have teeth that appear bright white. Everyone’s teeth naturally dull over time because of aging and the contact your teeth have with staining foods, such as chocolate and coffee. However, teeth-whitening treatments can help you keep your teeth white for life.

Get Regular Treatments

The effects of teeth whitening or bleaching treatments are only temporary, so regular treatments at Weaver Dentistry are necessary to keep your teeth white for life. Bleaching too frequently, though, can wear away your tooth enamel. The effects of in-office bleaching can last for several months to a year, while you may need to repeat your use of at-home bleaching kits every few months to maintain your white teeth. Whitening toothpastes do not contain bleach, so you can use them daily. The American Dental Association suggests asking your dentist for advice on which treatment is best for you.

Have Realistic Expectations

Not everyone’s teeth can be turned bright white, according to the American Dental Association. Your teeth may naturally be a light yellowish color that lends itself well to teeth-whitening procedures, but bleach is not likely to be effective for grayish teeth. Brownish teeth fall somewhere in between.

Practice Good Oral Hygiene

Your teeth whitening efforts will not be as effective if your teeth are in poor health. Visible fillings, implants, or bridges that are metallic stand out against the white color you want to achieve. You can help prevent tooth decay and reduce your risk of needing these unsightly treatments by maintaining a good oral hygiene routine. In addition to brushing your teeth twice a day to remove dirt and potential staining agents, the actions below can promote a healthy mouth.

• Floss every day
• Visit Weaver Dentistry regularly
• Rinse your mouth with water after each meal and snack
• Limit sugary and starchy foods and beverages, especially between meals
