Hearing that you need a root canal can be highly intimidating. What is a root canal? It is the removal of the nerve supply from the tooth. Here, Dr. James Robson will describe the parts of a tooth and explain the reasons for a root canal and how it is done when you visit us in our East Lyme, CT office.

Your tooth is made up of many layers. The outside layer is called enamel and is made of minerals. The middle layer is dentin, which is also a calcified tissue, but less dense. The center of the tooth is called the pulp, and that hosts the nerves and blood vessels. A root canal is the removal and replacement of this center with a sterile filling.

A root canal is needed when an infection spreads to the center of the tooth. This can be from trauma (recent or previous), a cavity, a severe crack, or other compromise that causes nerve damage. An X-ray and examination are required to see if a root canal is needed. Symptoms may include but are not limited to pain, swelling, change in tooth color, and over-reaction to temperature change or pressure.

When it is time to begin, you’ll receive local anesthesia (via injection) to make you most comfortable. A rubber dam is used to isolate the tooth, while other equipment determines the nerve location and maintains a sterile working environment. All of the infected area is removed including the nerve tissue and blood vessels. Then, medicines are used to sterilize and alleviate any pain. Next is the placement of a filling material in the spot where the nerve used to be.

When your nerve and blood supply are taken away, the tooth is non-vital, or dead, and can become weak and fragile. If your tooth is badly decayed, a large portion of it will have to be removed. It is recommended to place a crown on the tooth to keep the enamel from breaking or falling apart. If you do not get a crown, you could eventually lose the tooth to more decay or infection. The tooth could also break off completely and you would have to have an extraction. The crown fits over the top of the tooth and secures it from breaking down.

A root canal saves the life of a tooth that would otherwise succumb to further infection and eventually extraction. Infection is the cause of most-needed root canals. If you are ever unsure what is happening at your appointment, don’t be afraid to ask questions so you understand the procedure completely.

Fluoride is a mineral that plays an essential role in oral health. In fact, the significant reduction in American tooth decay in recent decades can be attributed to a greater availability of fluoride in public water supplies, toothpaste, and other resources. When it comes in contact with the teeth, fluoride helps protect the enamel from acid and plaque bacteria. In some cases, it can even reverse tooth decay in its earliest stages.

Despite the benefits of fluoride, tooth decay is still common, especially among teenagers. The Centers for Disease Control reports that cavities can be found in more than half of young teens and two-thirds of older teens over age 16. Many of those teens are deficient in fluoride, either due to a lack of public water fluoridation or the use of bottled water. So how can parents ensure their teens are getting the fluoride they need to facilitate strong, healthy teeth?

Monitor Fluoride Exposure

Dr. James Robson and our team at Robson Dentistry recommend you start by measuring your teen’s fluoride exposure. Make sure you purchase fluoridated toothpaste for your household, and find out if your tap water is fluoridated. If your teen primarily consumes bottled water, examine the bottle to determine whether fluoride has been added. The majority of bottled waters are not supplemented with fluoride, but those that are will be clearly labeled.

Fluoride Supplementation

Dr. James Robson may recommend topical fluoride treatments at routine dental exams. These treatments are painless for your teen and may help establish stronger enamel that is more resistant to plaque and tooth decay. If you have a public water supply that is non-fluoridated, we may recommend fluoride supplementation between visits. These can be administered as drops, tablets, or vitamins.

Keep in mind that fluoride is most important for children and teens under the age of 16. Be proactive about your teen’s oral health by speaking with us about your family’s fluoride needs at your next dental visit.

Every year, Americans all over the world celebrate the birth of the country and its independence on the Fourth of July. There are countless ways that people celebrate and they range from community parades and large scale gatherings to concerts, fireworks displays, and smaller scale celebrations among family and friends. For some people, July 4th is synonymous with baseball, while for others it is all about the beach of barbecues. However you celebrate, you can be sure that red, white, and blue is visible everywhere throughout the area.

The Beginnings of Fourth of July Celebrations

Although it wasn't officially designated as a federal holiday until 1941, the actual tradition of celebrating Independence Day goes back to the time of the American Revolution (1775 – 1783). At the time of the American Revolution, representatives from the 13 colonies penned the resolution that ultimately declared their independence from Great Britain. The continental congress voted to adopt the Declaration of Independence on July 2nd of 1776. Two days later, Thomas Jefferson's famous document that is now known as the Declaration of Independence, was adopted by delegates representing the 13 colonies.

First States to Recognize the Fourth of July

In 1781, Massachusetts became the first state (or commonwealth) whose legislature resolved to designate July 4th as the date on which to celebrate the country's independence. Two years later, Boston became the first city to make an official designation to honor the country's birth with a holiday on July 4th. In that same year, North Carolina's governor, Alexander Martin, became the first governor to issue an official state order stipulating that July 4th was the day on which North Carolinians would celebrate the country's independence.

Fun Facts About the Fourth of July

• The reason the stars on the original flag were arranged in a circle is because it was believed that would indicate that all of the colonies were equal.
• Americans eat over 150 million hot dogs on July 4th.
• Imports of fireworks each year totals over $211 million.
• The first “official” Fourth of July party took place at the White House in 1801.
• Benjamin Franklin didn't want the national bird to be the bald eagle. He believed that the turkey was better suited to the coveted distinction. John Adams and Thomas Jefferson disagreed with him, and he was outvoted, so the bald eagle became the official bird of the United States.

For many, the tradition is something entirely different. Along the coastal areas of the United States, people may haul out huge pots to have lobster or other types of seafood boils. Others may spend the day in the bleachers at a baseball game, or at a park, cooking a great traditional meal over an open fire. No matter how or where you celebrate, one thing is certain: all Americans celebrate July 4th as the birth and independence of our country.

Dr. James Robson and our team at Robson Dentistry wish you a safe and happy Fourth of July!

At Robson Dentistry, we have patients coming in asking us why a taste of ice cream or a sip of coffee becomes a painful experience, or why brushing or flossing makes them wince or cringe. The answer, usually, is sensitive teeth. Tooth sensitivity typically occurs when the underlying dentin layer of the tooth is exposed in the oral cavity, and most people experience tooth sensitivity at some point in their lives.

So, why do people experience sensitivity and how do you know if tooth sensitivity is something to be worried about? The most common cause of the sensitivity is exposure of the dentin, which is the layer surrounding the tooth’s nerve. Contributors to tooth sensitivity include teeth whitening and dental work such as fillings, periodontal treatment, and the placement or adjustment of braces. These are temporary and should be of no concern.

Permanent hypersensitivity, however, may require treatment at Robson Dentistry. The first step is to determine the cause, and that begins with a visit to our East Lyme, CT office.

The reasons your teeth may become sensitive vary, but possible causes include:

• Tooth decay (cavities) near the gum line
• Cracked or fractured teeth
• Fillings that are worn
• Gum (periodontal) disease, or recession of the gums
• Worn tooth enamel
• Brushing too hard
• Consuming acidic foods

Dr. James Robson and our team at Robson Dentistry want you to know that sensitive teeth can be treated, and the type of treatment will depend on what is causing the sensitivity. Dr. James Robson may suggest one the following treatments:

• Desensitizing toothpaste, which contains ingredients that seal off the microtubules inside the exposed dentin to reduce tooth sensitivity
• Fluoride gel, which strengthens compromised tooth enamel, helps prevent tooth decay, and decreases hypersensitivity of the teeth
• A crown, inlay, or bonding, which is used to treat tooth decay and prevents sensitivity
• A surgical gum graft. If gum tissue has been lost from the root, this procedure will protect the root and reduce sensitivity.
• Root canal: If you are experiencing severe and persistent sensitivity which cannot be treated by other means, Dr. James Robson may recommend you undergo a root canal to eliminate the problem.

If you are experiencing tooth sensitivity, give us a call today so that Dr. James Robson can provide you with some much-needed relief!
