What is Root Canal Treatment? Your Essential Guide to Pain-Free Dental Care For Nervous Patients

Everything you need to know about root canal treatment

Did you know that 9 out of 10 root-treated teeth survive for 8 to 10 years? What is canal root treatment actually involves is a tooth-saving procedure performed about 15 million times annually in the United States alone.

Despite its intimidating reputation, what is root canal treatment but a pain-relieving procedure rather than a painful one. Many patients walk into our clinic with visible anxiety, expecting the worst, but leave wondering what all the fuss was about.

The treatment becomes necessary when you experience symptoms like pain while eating hot or cold food, discomfort when biting, or swelling around the affected tooth. Without treatment, these issues can lead to serious complications, including infection spreading to other teeth and potential jawbone damage.

In this guide, we’ll walk you through everything you need to know about root canal treatment – from the three main steps involved to aftercare advice. We’ll also debunk common myths and explain why choosing this treatment is generally less expensive than extracting and replacing the tooth with alternatives like crowns or bridges.

If you’re feeling nervous, you’re not alone – but we’re here to reassure you with facts rather than fear.

Understanding What a Root Canal Really Is

Root canal treatment remains one of the most misunderstood dental procedures, yet approximately 15 million teeth are treated and saved through this method each year. Let’s clear up exactly what this procedure involves and why modern techniques have transformed the experience.

What is root canal treatment?

Root canal treatment (also known as endodontic therapy) is a dental procedure designed to remove infected or inflamed pulp from inside a tooth. The pulp is the soft tissue containing nerves, blood vessels, and connective tissue that keeps your tooth healthy.

When this inner tissue becomes compromised through deep decay, repeated dental procedures, cracks, or trauma, the procedure becomes necessary. Essentially, the treatment involves:

Removing the damaged pulp from the tooth’s interior
Carefully cleaning and disinfecting the root canal system
Filling and sealing the space to prevent reinfection

Following this procedure, a crown or filling is typically placed to protect and restore the tooth to full function. Contrary to common belief, root canal treatment doesn’t remove the roots of your tooth—only the infected tissue inside them.

Why it’s not as scary as it sounds

The phrase “root canal” often evokes unnecessary fear. Around two-thirds of Americans list pain as their main concern regarding root canal therapy. However, modern techniques have dramatically improved the patient experience.

Firstly, the procedure doesn’t cause pain—it eliminates it. The discomfort people associate with root canals actually comes from the infection the treatment resolves. During the procedure, dentists use effective local anaesthetics to ensure you remain comfortable throughout.

Furthermore, although some believe root canals cause illness, this myth stems from poorly designed research conducted nearly a century ago. In fact, modern research shows patients with multiple endodontic treatments had a 45 percent reduced risk of cancer.

The success rate is remarkably high, with approximately 9 out of 10 root-treated teeth surviving for 8 to 10 years. Additionally, most treatments can be completed in just one or two appointments, depending on the condition of your tooth and your personal circumstances.

For those concerned about cost, consider that saving your natural tooth through root canal treatment is often less expensive than extraction followed by implant or bridge placement. These alternative procedures tend to cost more and may affect surrounding healthy teeth.

Root canal treatment has evolved significantly. Modern technology and anaesthetics have made the procedure no more painful than receiving a standard filling. Consequently, there’s no need to fear this tooth-saving procedure.

What to Expect Before and During the Procedure

The patient journey through a root canal procedure involves several well-defined stages, all designed to ensure effective treatment with minimal discomfort.

Initial consultation and X-rays

Your dentist will begin with a thorough examination of the affected tooth. X-rays play a crucial role in this stage, helping to build a clear picture of your root canal and assess the extent of any damage. These images allow your dentist to plan the treatment effectively and confirm whether root canal therapy is indeed necessary. Initially, they may also perform sensitivity tests by gently tapping on your tooth or touching it with hot or cold substances.

How dentists keep you comfortable

Root canal treatment is usually carried out under local anaesthetic, which numbs the infected tooth and surrounding gum area. For patients with dental anxiety, sedation options might be available, including nitrous oxide (laughing gas) or oral sedatives. Prior to beginning the procedure, your dentist will place a thin rubber sheet called a dental dam around the tooth to isolate it, keeping it dry and free from saliva. This protective barrier also prevents you from swallowing any chemicals used during treatment.

Step-by-step breakdown of the treatment

Once properly numbed, the procedure unfolds as follows:

Your dentist creates a small opening in the crown of your tooth to access the pulp chamber
Specialised instruments are used to remove the infected pulp tissue, nerves, and blood vessels
The inside of the tooth is thoroughly cleaned and disinfected
The cleaned canals are filled with a biocompatible material (usually gutta-percha)
The tooth is sealed with a filling or, ultimately, a crown for protection

How long does it take?

A root canal typically requires 30-90 minutes per appointment. The duration largely depends on which tooth is being treated—molars with multiple roots can take approximately 90 minutes, while front teeth might require only 45-60 minutes. Most procedures are completed in one or two visits. Subsequently, a final appointment for crown placement may be necessary, taking about 60 minutes.

Pain, Myths and Comfort: Reassurance for Nervous Patients

Dental anxiety is exceptionally common when it comes to root canal treatment, with up to 36% of the American population experiencing some form of dental anxiety. Let’s address the concerns that might be keeping you awake at night.

Does a root canal hurt?

The most persistent concern about root canal treatment is pain. Yet, contrary to popular belief, root canal procedures are typically painless. The discomfort actually comes from the infection the treatment resolves. Most patients experience less pain afterwards because the source of the problem—infected pulp—has been removed.

Your tooth may feel sensitive for the first few days after treatment, which is perfectly normal. For most patients, over-the-counter painkillers like paracetamol or ibuprofen are sufficient to manage any temporary discomfort.

Pain relief options and anaesthesia

Modern dentistry offers several effective options to ensure your comfort:

Local anaesthesia: The most common method, blocking nerves from transmitting pain signals
Nitrous oxide (laughing gas): Minimises anxiety while used alongside local anaesthesia
Oral sedation: Creates a sense of relaxation for those with moderate dental anxiety
IV sedation: Sometimes called ‘sleep dentistry’, leaves you relaxed and with minimal memory of the procedure

Notably, pre-treatment analgesia administered 30 minutes before the procedure can effectively reduce postoperative pain.

Common myths vs reality

Many fears stem from outdated information or misconceptions:

Myth: Root canal treatment is painful. Reality: With modern techniques, it’s no more uncomfortable than having a filling.

Myth: Root canals cause illness elsewhere in the body. Reality: This stems from poorly designed research conducted nearly a century ago. Modern studies show patients with multiple endodontic treatments had a 45% reduced risk of cancer.

Myth: It’s better to extract the tooth. Reality: Saving your natural tooth is always preferable and often less expensive than alternatives.

Myth: The roots are removed during treatment. Reality: Only the infected pulp is removed—your roots stay intact.

Aftercare and Long-Term Tooth Health

Proper aftercare following your root canal treatment is crucial for ensuring the long-term success of the procedure. A properly treated and restored tooth can last as long as your natural teeth with the right care.

What to do after the procedure

Immediately after treatment, your tooth and surrounding gums need special attention. As the anaesthetic wears off, you might feel some tenderness in the area for a few days—this is perfectly normal. For most patients, over-the-counter medications like paracetamol or ibuprofen effectively manage any discomfort.

Throughout the first few days:

Avoid eating or drinking for the first 30 minutes
Stick to soft foods like well-cooked pasta, mashed potatoes, yoghurt, and smoothies
Apply a cold compress to the face near the treatment area to minimise swelling
Avoid strenuous activities for at least a day or two

How to care for your treated tooth

Once your root canal and follow-up appointments are completed, you’ll need to return to your dentist for a final crown to fully restore the tooth. This step is vital—studies show that delays in placing permanent restorations can increase the chance of reinfection.

For long-term care:

Resume regular brushing and flossing, being gentle around the treated area
Avoid chewing on hard foods or using the treated tooth for biting until cleared by your dentist
Attend regular dental check-ups and cleanings

Research demonstrates impressive longevity for treated teeth. The probability of a tooth surviving 10, 20, and 30 years after endodontic treatment is 97%, 81%, and 76%, respectively. Accordingly, with proper care, your treated tooth can serve you for decades.

When to call your dentist

Contact your dentist immediately if you experience:

Severe pain or pressure lasting more than a few days
Visible swelling inside or outside your mouth
An allergic reaction to medication
Your bite feels uneven
The temporary crown or filling comes out
Symptoms you experienced prior to treatment return

Remember, putting off treatment for complications can lead to losing your tooth or allowing infection to spread to other teeth or your jawbone. Throbbing pain may indicate there’s still infected pulp in your tooth requiring attention.

Overall, with proper care and regular dental check-ups, your root canal-treated tooth can remain functional and pain-free for many years to come.

Root canal treatment undoubtedly remains one of the most misunderstood dental procedures despite its high success rate and pain-relieving benefits

Throughout this guide, we’ve debunked common myths that cause unnecessary anxiety among patients. Contrary to popular belief, modern root canal therapy is virtually painless, thanks to effective anaesthesia and advanced techniques.

Most importantly, this tooth-saving procedure offers a cost-effective solution compared to extractions followed by implants or bridges. With proper care, your treated tooth can survive for decades—studies show 97% survival rates after 10 years and 76% after 30 years.

Aftercare plays a crucial role in ensuring long-term success. Therefore, following your dentist’s instructions about medication, diet, and oral hygiene will significantly improve outcomes. Additionally, completing the final restoration with a crown provides essential protection for your treated tooth.

Fear should never prevent you from seeking necessary dental care. Book a root canal treatment consultation at Dr Richard Clinics in the Harley Street district of London now if you’re experiencing symptoms like persistent tooth pain, sensitivity to temperature, or swelling.
