At Weaver Dentistry, we know the human mouth contains a lot of bacteria. A bacterium can travel through your body with routine activities that are a normal part of daily living. You spread bacteria when you brush or floss your teeth, when you chew, and when you swallow.

For most people, bacteria don’t cause any problem. For some people, however, especially those who have chronic medical conditions, specific cardiac conditions, or whose immune systems are compromised, bacteria that spreads throughout the bloodstream can lead to much more serious bacterial infections.

The goal of pre-medication or antibiotic prophylaxis, Dr. Gregory Weaver will tell you, is to prevent bacterial endocarditis, a serious infection of the endothelial heart surfaces or the heart valves. The condition is also called infective endocarditis. A small population of people with certain health problems has a high risk for contracting this potentially deadly bacterium.

The American Heart Association states that people at greatest risk for contracting bacterial or infective endocarditis are:

• Patients who underwent cardiac valve surgery in the past
• Those who have suffered past incidents of infective endocarditis
• Patients who have mitral valve prolapse, resulting in or causing valve leakage
• People who have had rheumatic fever or any degenerative cardiac condition that produces abnormalities in cardiac valves
• Patients who suffer from certain congenital heart diseases

For these patients, any dental procedure may cause bleeding, and prophylactic antibiotic administration is recommended as a preventive measure.

Other patients who require prophylactic antibiotics

The American Association of Endodontists extends recommendations to patients who have undergone joint replacement surgery within the past two years, suffer from type 1 diabetes, or have immune deficiencies from diseases such as lupus, rheumatoid arthritis, or HIV; cancer patients whose immune systems are suppressed because of radiation or chemotherapy; people who have had organ transplants; and hemophiliacs.

The American Academy of Pediatric Dentistry also includes people who suffer from sickle cell anemia, as well as patients who suffer from conditions that require chronic steroid therapy.

Typical endodontic procedures for which antibiotic prophylaxis is recommended include root canal therapy (when it involves going deeper than the root apex), surgical tooth extractions, and any other dental, endodontic, or periodontal procedure during which the doctor anticipates bleeding.

Although different medical societies and organizations offer these guidelines as a way of identifying patients for whom prophylactic pre-medication is essential prior to dental procedures, dentists will take each patient's medical history and personal risk factors into consideration. Some doctors may choose to administer antibiotics following a procedure, especially for patients who have previously suffered from oral infections either as a result of dental procedures or that necessitated oral surgery.

Did you know there are as many types of dental fillings as there are flavors of ice cream? Okay, maybe that’s an exaggeration. Still, when you visit the dentist with a cavity, there are many filling options. Most of us just sit in the chair, open our mouths, and let the dentist work his or her magic. But have you ever stopped to consider what the dentist is filling and restoring your decayed or broken tooth with?

Five types of dental fillings

There are five basic kinds of dental filing material. The dentist decides which type to use based on the degree of the decay, the cost of the material, and the type of dental insurance you have.

1. Dental amalgam, or silver fillings, have been used to fill cavities for more than 150 years. Dental amalgam is the most common type of dental filling. It's strong, durable, and less expensive than other types.
2. Composite fillings, or white fillings, are popular because the color matches the rest of your teeth. Composite fillings are a combination of resin and plastic. They are more aesthetically pleasing than silver fillings, but are also less durable.
3. Ceramic fillings are durable and visually appealing (tooth-colored), but they are expensive. They are made of porcelain and have been shown to be resistant to staining.
4. Glass ionomers are typically used on children whose teeth are still changing. Constructed from glass and acrylic, glass ionomers are designed to last fewer than five years. The benefit of these dental fillings is that they release fluoride, which protects the changing tooth from further decay.
5. Unless you’re a rock or movie star, gold fillings aren’t common. While a gold filling is durable, non-corrosive, and can last more than 15 years, it not only takes more than one dental visit to place, but, as you can imagine, it is expensive.

On March 17, everyone has a little Irish in them. St. Patrick’s Day is a joyous celebration of Irish heritage. The holiday originated as a commemoration of Saint Patrick, who brought Christianity to Ireland. The saint arrived in Ireland in 432 and earned the reputation of a champion of Irish Christianity. March 17th, the day of St. Patrick’s death, has been commemorated by the Irish for over 1,000 years. St. Patrick’s Day is still observed as a religious feast day by several Christian denominations, but it is better known in the public imagination as a rich celebration of Irish culture.

St. Patrick’s Day has been an official public holiday in Ireland since 1903. Each year, the Irish celebrate with a several-day festival that includes theater performances, music, fireworks, and festive parades. The celebration is also a public holiday in Northern Ireland, Montserrat, and Newfoundland and Labrador. In other parts of the world with heavy Irish populations, it is an unofficial celebration of Irish heritage. Parts of Great Britain, Canada, Argentina, South Korea, Switzerland, New Zealand, the United States, and Australia commemorate the holiday each year. Typical celebrations in these countries include drinking green beer, wearing green, eating traditional Irish foods, parades, and shamrock decorations.

Many people, Irish and non-Irish alike, take part in the “wearing of the green” on St. Patrick’s Day. In fact, the color originally associated with Saint Patrick was blue. His use of shamrocks to explain the Holy Trinity to the Irish made the green clover emblematic of the holiday, leading to the traditional green attire worn by thousands on St. Patrick’s Day. Other little-known facts about St. Patrick’s Day include the following:

• Each year, the United States and Ireland face off in a rugby competition called the “St. Patrick’s Day Test.”
• Montreal celebrates the holiday with an annual parade, which has been held each year since 1824. The Montreal city flag even features a shamrock in its corner, as a nod to its Irish heritage.
• The Guinness World Records named St. Patrick’s Day the “Friendliest Day of the Year.”
• Along with Valentine’s Day, St. Patrick’s Day is one of the most widely celebrated saint’s day in the world.

No matter your cultural heritage, St. Patrick’s Day is a great time to let loose and celebrate your inner Irish-ness! Don your greenest attire and exclaim “Erin go Bragh!” (Ireland forever!) to everyone you meet. From Dr. Gregory Weaver - have a great St. Paddy’s day!

There are different situations for which Dr. Gregory Weaver may recommend a crown, and Dr. Gregory Weaver will recommend different types of crowns depending on your unique situation. Dental crowns are made from various materials, including all-metal, porcelain-fused-to-metal, all-ceramic or porcelain, or resin. The material the crown is made of will dictate the length of time you may have to wait for it, whether or not you will need a temporary, and of course, the cost.

A crown is a protective cap. Possible reasons Dr. Gregory Weaver may want to give you a crown include:

• To cover a tooth after a root canal
• To cover a cracked or broken tooth
• To cover a weak tooth, either because of a large filling, or because of the likelihood that it will crack or break
• To cover an implant
• To cover anchor teeth that support a bridge

CEREC crowns

CEREC crowns are made of a solid block of ceramic or resin materials. This type of crown is made right in our office during a single visit. There is no need to construct a temporary crown, take impressions for the permanent crown, and wait for the crown to be made at an off-site dental laboratory to be returned to Weaver Dentistry about a month later.

This type of crown uses computer technology to take a picture of the tooth that will receive the crown, as well as the surrounding teeth. Thanks to CAD software that works with this system, Dr. Gregory Weaver can design the tooth while looking in your mouth, and make sure the color matches the rest of your teeth. Also, because the crown is made from a single block of material, it is considerably stronger than many other types of crowns.

Types of traditional crowns

All metal: All-metal crowns don’t require as much tooth preparation, and therefore don’t alter the existing tooth structure as much as porcelain-fused-to-metal or ceramic crowns. They are the longest-lasting type of traditional or permanent crown, and are far less likely to break or chip. Metals used may include gold alloy, palladium, nickel, or chromium.

Porcelain fused to metal: Porcelain can be matched to your natural tooth color. A disadvantage, however, is that these types of crowns create more stress and wear on the surrounding teeth than either pure metal or resin. The metal sometimes shows through at the bottom of the tooth, near the gum line. Porcelain can chip or break, but can be made to look exactly like your real teeth.

All ceramic/all porcelain: This type of crown is most easily matched to your existing teeth. Because there is no metal, there is no risk that it will show. This type of crown is ideally suited to people who have metal allergies. The greatest disadvantage is that ceramic or porcelain may cause more wear and tear to the surrounding teeth. On the other hand, it is ideal for front teeth because they look very much like real teeth.

Resin: Resin crowns are cheaper than ceramic, porcelain, or metal crowns. This material is more prone to fracturing and causes more wear and tear on the crown itself.

Different situations warrant different types of crowns. Dr. Gregory Weaver will discuss your situation and determine which type of crown you need. Our team at Weaver Dentistry is happy to answer any questions you may have about crowns, CEREC, or any other aspect of your oral health.
