Tooth decay affects everyone, with studies reporting that 92% of adults have had a cavity at one point in their lifetime. In more serious instances of tooth decay, however, the nerve of the tooth may become infected. This type of infection requires a root canal, in which the affected nerve is removed, and the interior of the tooth is cleaned and filled.

Tooth Anatomy

Although each tooth is covered by a hard outer shell, the interior of a tooth consists of dental pulp. This pulp is soft, containing blood vessels that bring nutrients to the tooth. Each tooth also has an associated nerve, which resides within a root canal passing from the tooth’s root into the dental pulp. This nerve provides information about temperature, allowing teeth to sense heat or cold.

Symptoms of Nerve Infection

Damage to the dental pulp or nerve tissue leads to a rapid multiplication of bacteria within the interior of the tooth. The result may be an abscess, a small pocket near the root of the tooth that becomes full of pus. This infected area commonly causes the following symptoms:

• Intense pain or sensitivity when pressure is applied to the tooth
• Sensitivity to hot or cold temperatures, even after the heat or cold has been removed
• Darkening or discoloration of the affected tooth
• A small, persistent pimple that forms on the gums
• Swollen or tender gums
• Swelling in other areas of the face, neck, or head

Nerve infection may occur due to deep decay, although repeated dental procedures, facial trauma, chipping or cracking of a tooth, or large fillings may also contribute to an abscessed tooth.

What to Do if You Think You Need a Root Canal

Only a visit to Dr. Vincent Cardinale and Dr. Chris Moody can confirm whether a tooth’s nerve has become infected. We will perform an oral examination and X-rays to confirm whether the tooth is abscessed. If a root canal procedure is needed, a small hole will be placed in the tooth. The pulp and nerve tissue are removed from the tooth, which is thoroughly cleaned and filled. Then, the hole is sealed with a special compound to prevent bacteria from entering the tooth’s interior. The entire procedure is performed under local anesthesia to numb pain.

If you think you may have tooth or nerve decay, call our Naples, FL office today to schedule a diagnostic appointment.

It is not uncommon to be concerned about your safety when you have dental X-rays performed. Putting on a heavy lead vest may make you apprehensive. The benefits of dental X-rays far outweigh the risks when safety procedures are followed and the number of X-rays is limited to the required number.

About Dental X-rays

Intraoral X-rays are the most common, and include bitewing X-rays. These allow Dr. Vincent Cardinale and Dr. Chris Moody and our team at Cardinale Dentistry to detect caries (cavities) and check the health of your bone and root structure. Extraoral X-rays provide the information we need to monitor your jaw and temporomandibular joint (TMJ), as well as look for impacted teeth and tooth development.

X-ray Safety

A set of four bitewing X-rays exposes you to about 0.005 mSv (millisievert) of radiation, which is equal to the amount of radiation you receive in an average day from natural sources. A panoramic X-ray exposes you to about twice the amount of a bitewing. In both cases the risk is negligible and worth the diagnostic benefits.

Guidelines from the American Dental Association are offered for individuals who are not at high risk for cavities. Children in this group should have X-rays every one or two years. Teenagers should have X-rays every one-and-a-half to three years. Adults can go two to three years between X-rays. If you are at higher risk, yearly X-rays are not harmful and can save your teeth.

No matter what type of X-ray you are having, it is extremely important to tell Dr. Vincent Cardinale and Dr. Chris Moody or one of our technicians if you are pregnant or may be pregnant. If you are concerned about the number of X-rays you are having done, or about any radiation you are exposed to, please give us a call at our convenient Naples, FL office and talk to us about your concerns.

When we talk about teeth, every single one of yours counts. Whether you’ve lost a tooth due to injury or poor oral hygiene, it’s worth seeing Dr. Vincent Cardinale and Dr. Chris Moody to evaluate all your replacement options. If you don’t, you could suffer negative effects to your teeth, gums, jawbones, appearance, and self-esteem.

Depending on how many teeth are missing and where they are located, Dr. Vincent Cardinale and Dr. Chris Moody may suggest an implant, fixed bridge, or a removable bridge.

Addressing missing teeth as soon as possible is in your best interests. If you don't, the consequences might include:

• Shifting teeth: When you lose a tooth, the space it creates allows the neighboring teeth to drift and move out of alignment. A once-straight smile and correct bite can quickly turn into crooked teeth and a misaligned bite.
• Tooth decay and/or gum disease: After teeth have shifted, it can be harder to reach all areas around them to brush and floss properly. The buildup of bacteria and plaque can result in periodontal disease and the loss of your remaining teeth due to decay.
• Effect on jaws: Missing teeth alter your bite and how your teeth and jaws contact one another. This puts added strain on your jaw joint (TMJ) and can contribute to the development of TMJ disorder.
• Change in face and appearance: When you lose a tooth, your gums and your jawbone are no longer stimulated in that area. A dental implant replaces the root of a tooth or several teeth, and provides stimulation to prevent bone loss. If the root isn’t replaced, this can lead to deterioration of the jawbone and alteration of the shape and appearance of your face. Your face, especially the cheeks, can look older and more sunken.

Replacing missing teeth is an essential step for your physical and emotional health. If they are replaced in a timely manner at our Naples, FL office, you’ll continue to have the same wonderful smile you’ve always had.

A root canal entails the removal of the nerve supply from a tooth. If you know the purpose of a root canal, the process may seem a little less intimidating.

Dr. Vincent Cardinale and Dr. Chris Moody will explain the steps in person before your scheduled root canal. Here are some reasons why you may need one and how it will be done when you visit our Naples, FL office for your appointment.

Let’s look at the parts of a tooth. Teeth are made up of layers. The outside is the enamel you see, which is composed of minerals. The middle layer is called dentin. It is less dense and made of calcified tissues.

The center of the tooth, also known as the pulp, holds the nerves and blood vessels. When a tooth has decayed or been infected all the way down to the pulp, a root canal is used to remove and replace the root with a filling.

A cavity, sudden trauma, severe cracks, or other events that may cause nerve damage can start an infection of the root of your tooth. You may notice an infection if you experience abnormal pain, swelling, sensitivity, or change in tooth appearance.

Don’t hesitate to contact our Naples, FL office to schedule an examination if you notice these symptoms. We may need to take X-rays of the problem tooth to find out if a root canal is necessary.

Once an appointment is scheduled for a root canal and we’re ready to begin the procedure, you’ll be given anesthesia to keep you comfortable. The problem tooth will be isolated and sterilized. We work to remove all the infected area after that.

The treatment will include getting rid of nerve tissue and blood vessels, then filling in the spot where the nerve used to be. A crown is placed over the area to secure enamel from breaking down in the future and prevent the potential loss of the tooth. The root canal can block the possibility of having your tooth extracted due to decay or infection.

If you have further questions about root canals or notice any new issues in your mouth, please don’t hesitate to call our office and speak with a member of our staff. We’d be happy to answer your questions and schedule an appointment for you to come and get your problem tooth checked out.

Don’t forget: You can avoid having to undergo a root canal if we catch the problem early on!
