Root Canal

A tooth infection often leads to painful side effects and can spread to other teeth if left untreated.

Drs. Jeffrey Kleinheinz and Katrina Ashlin can restore your health with a single-appointment root canal at our Charlotte, NC, practice.

If you notice symptoms of decay or infection, it is important to schedule root canal therapy right away.

Why Do I Need A Root Canal?

Plaque and tartar are bacteria-rich substances that get trapped on your teeth, often due to poor brushing and flossing techniques. Bacteria can eat away at tooth enamel and can eventually reach the tooth's inner chamber, which is filled with soft tissue known as dental pulp. When the pulp becomes inflamed, you will need root canal therapy to remove the diseased pulp and prevent the spread of infection.
In the tooth, plaque builds and destroys enamel and dentin. The infection in the tooth pulp can spread to the nerves, bones, and surrounding tissues, and bacteria forms an abscess.
Your teeth are made up of many parts. The innermost layer of the tooth, called the pulp, is made up of blood vessels, connective tissue, and nerve cells. During a root canal, your dentist extracts the infected pulp and restores the tooth.

Symptoms of a Root Canal Infection

There are several common warning signs that indicate a root canal infection. Schedule a consultation at our Charlotte, NC, practice if you experience:

  • Sharp, sudden pain when biting down
  • Swollen gums
  • Sensitive gums and teeth
  • Constant pain in your tooth

It is embarrassing to admit how long it had been since I set foot into a dentist office (> 10 years). As always, neglect leads to a problem and the problem pushed me to find a great dentist! A friend recommended the Kleinheinz dental practice. Walking into the office, you will instantly feel at home with the friendly, professional staff. During my initial visit and treatment, Dr. K and the rest of the team did a fantastic job getting my teeth cleaned, discussing treatment options and answering all of my questions. I have since been back several times starting down the path to a healthier and straighter smile! You will not find a better dental practice in Charlotte.

But Isn't Root Canal Treatment Painful?

There is a common misconception that a root canal involves significant discomfort and downtime. In reality, treatment is relatively simple and pain-free. Local anesthesia and sedation make a root canal no more bothersome than a standard filling. Avoiding treatment, on the other hand, can lead to severe pain and may even destroy the tooth altogether. Once decay and infection reach a certain point, you will have no choice but to extract the tooth and undergo restorative treatments, which can be both expensive and time-consuming.

A Closer Look at the Root Canal Procedure

Here is what you can expect during root canal treatment at our Charlotte dental practice...

Numbing the Mouth

Before we start the root canal, your dentist will administer an anesthetic to numb both your tooth and the surrounding area. We will begin the dental procedure once you are perfectly comfortable.

Accessing the Root Canal

Dr. Kleinheinz creates a small opening in the tooth using special rotary instruments. Then we carefully remove the pulp and thoroughly clean the inner tooth chamber.

Filling the Chamber

Once the tooth is sterile, we will fill the pulp chamber with an inert rubber substance to replace the extracted pulp. The entire area is then covered with a protective adhesive cement to seal off the small hole.

Crowning the Tooth

Finally, your dentist will cap the tooth with a custom dental crown to reinforce the outer layer and prevent future damage. Depending on the materials you prefer for your crown, we may be able to complete this step in the same appointment.

Post-Root Canal Therapy Instructions

It is normal to experience mild swelling and sensitivity immediately after root canal therapy. We recommend eating soft foods for a day or two and being especially cautious while brushing around the area. If you have questions about your root canal or recovery, please send us a message. We will be happy to assist you.

Root Canal FAQ

I get incredibly nervous about dental work. Is there anything that can help me?

Dental phobia is a fairly common problem and can be easily treated with sedation dentistry. If you have trouble undergoing dental work due to anxiety, low pain tolerance, or high levels of sensitivity, please ask our dentists about sedation. We can discuss your needs and find an option that can work for you.

Does insurance cover root canal treatment?

Root canals are considered a necessary restorative procedure and are therefore covered by most insurances. Our dentistry team can contact your insurance provider to find the details of your plan and make sure you receive your benefits for treatment. If you do not have insurance, we also offer financing options to help make treatment more affordable.

What if my tooth cannot be repaired with a root canal?

The sooner you schedule an appointment after noticing symptoms of an infection, the more likely we save your tooth with a root canal. However, if the infection is too severe, we may recommend extraction. This will prevent the spread of bacteria to surrounding teeth and additional health problems. Once your smile is healthy again, we can replace the tooth with an implant-supported crown or a dental bridge.
