Patients often ask our staff at Phoenix Endodontic Group questions about their root canals looking to better understand what they will experience. Many people are concerned about the severity of the procedure or how much recovery time to plan for.

The good news is that many root canals have a quick recovery time – often just a week of special post-operative care. Many factors can impact your individual outcome, though, so it is important to understand the circumstances that brought you to the endodontist in the first place. Here’s a short list of some situations that can make the root canal procedure itself or your post-op period require extra care to ensure the root canal is successful.

What Makes A Root Canal A Serious Procedure?

1. When there is pre-existing infection or tooth damage. A crack or chip can let infection deep into a tooth’s pulp. Extensive tooth decay can also reach the pulp. If the infection causes an abscess, antibiotics may be needed first to eliminate the bacteria so the root canal can safely seal the roots so infection does not happen again.

2. When the tooth involved has multiple roots. The level of complexity involved with cleaning and sealing canals during a root canal increases with the number of canals in the tooth receiving treatment. Molars have up to four canals; premolars have one or two; canines and incisors have just a single canal.

3. When you don’t contact your endodontist if you have aftercare problems. An ordinary root canal can escalate quickly to challenging if you do not promptly call your endodontist when you experience pain that is severe or rapidly increasing; if the temporary filling placed in the tooth comes out; or if you can see swelling inside or outside of your mouth.

4. When you don’t return for your permanent crown as scheduled. The tooth being treated with a root canal should receive a permanent crown about two weeks after the procedure. Crowns provide structural support, protect the tooth from infection, and reduce nerve sensitivity to hot or cold foods and beverages. Not getting a permanent crown leaves your tooth vulnerable to further damage or infection and possible the failure of the root canal.

“The seriousness of each root canal is impacted by a patient’s individual oral health,” says Dr. Susan L. Wood, of the Phoenix Endodontic Group. “We are happy to explain our assessment of your situation and provide tips for making your root canal successful and stress-free, so it can help you hold on to your natural tooth for the rest of your life.”

Popular culture often associates lasers with science-fiction weapons or real-life space exploration, but the technology can also be used inside the human body. At the Phoenix Endodontic Group, our endodontists frequently use laser-based tools to assist in root canal treatments.

The practice uses laser technology manufactured by Fontana (SSP and SWEEPS®) and Biolase (Waterlase) at its Phoenix office location. Both brands of tools provide extra assistance in the critical phases of cleaning and disinfecting tooth roots during a root canal treatment.

Lasers Bring Benefits During A Root Canal Treatment

1. The laser can provide initial cleaning in the coronal (crown) area of the tooth. An endodontist will begin a root canal by creating an opening in the crown. The laser can be used in this area of the tooth to remove calcifications and biological debris.

2. The laser can assist cleaning of the root canals. After a canal has been prepared using files or other tools, the endodontist may flood the canal with water and activate the laser while withdrawing the water from the space. The laser creates vapor bubbles, which collapse to form microbubbles and a pressure wave; these phenomena are what clean biofilm from the canals.

3. Laser treatment can also help disinfect the canals as they are being irrigated. Once the endodontist shapes the canals with their files, they will irrigate them with disinfecting liquids. Lasers can be used at this point to augment the disinfection process, with the pressure wave created by the vapor bubbles pushing the disinfectant deep into the canal recesses and generally making the process more effective than the traditional disinfecting step by itself.

4. Finally, lasers can be used to remove the chemical disinfectants prior to filling the canals. After the canals have been cleansed, shaped and disinfected, the laser tool can be used to remove the disinfecting liquid in the canals by activating it for about 30 seconds to vaporize any remaining liquid.

According to Dr. Jacqueline S. Allen, who practices at the Phoenix Endodontic Group, “One significant advantage to using lasers during root canals is that they can provide a more thorough removal of bacteria, debris and other materials without the risk of apical (tooth root area) extrusion.” She continues, “We are happy to explain to patients how we use Fontana and Biolase laser technology to enhance the safety and effectiveness of their root canal treatments.” 

Fixing a cracked tooth can be like figuring out the damage after a car accident. If you don’t have a professional check things out, what looks like a surface dent can actually turn out to be really serious. Since dental bone does not behave like other types of bone and cannot knit itself back together, a chip or a crack to the tooth is likely to get worse over time.

In the case of a cracked tooth, your repair expert is an endodontist. Endodontists are experts in saving natural teeth. They frequently see clients with a cracked tooth, and can use their dental specialty training to determine if additional intervention such as a root canal is needed before placing a crown on the tooth.

When Does A Cracked Tooth Need A Root Canal Before A Crown?

The main job of a dental crown is to provide structural support by acting as the new outer surface of a tooth. Before a crown is cemented into place, your endodontist will want to make sure the natural tooth underneath the crown is as healthy as possible. If there is any injury or infection in a tooth’s nerve pulp, a root canal can provide a healthy tooth underneath.

With a crack deep enough to damage the root pulp, a root canal will be needed to prevent further difficulty, possibly extraction. It can be difficult to tell from symptoms alone if you need a root canal before you get a crown placed on your cracked tooth. Some cracked teeth that need a root canal before the crown hurt a lot; some do not. Some teeth with large cracks do not have root/nerve damage, but some teeth with much smaller cracks may have infected nerve pulp that must be removed via a root canal.

It’s important to see your endodontist right away because there are some types of cracked tooth injuries that cannot be remedied with a root canal and a crown. If the crack in the tooth extends below the gum line, it’s highly likely that the tooth will need to be extracted.

“It’s vital to have an endodontist perform a careful evaluation of a cracked tooth – what you can see on the surface may not be an accurate picture of the entire situation,” says Dr. Susan L. Wood, who practices with the Phoenix Endodontic Group. “Our office can perform the diagnostic procedures needed to determine if a root canal is called for before a crown is placed on the tooth.”

Although advancements in technology and microsurgical techniques have made root canals more comfortable and less stressful, the procedure still requires significant investment of time, money, and care. Root canals aren’t inevitable, though – you can reduce your risk of needing one with targeted, proactive self-care.

The tips below can help you prevent a root canal. They focus on managing your risk of falling prey to the three major causes of root canals: tooth decay, infection, and injury. By diligently following these tips, you can greatly lower your chance of needing a root canal, or developing serious oral health problems.

Keeping Teeth Strong And Healthy: 5 Tips For Avoiding A Root Canal

1. Brush your teeth twice a day. A twice-daily toothbrushing routine is the first line of defense against tooth decay, a major contributor to the type of dental pulp infections that require a root canal to resolve. Use an American Dental Association (ADA) approved fluoride toothpaste on a soft-bristled toothbrush.
2. Floss your teeth once a day. This will amplify the effectiveness of brushing your teeth. Flossing cleans the 40 percent of tooth surfaces that cannot be reached by brushing.
3. Strengthen your teeth with calcium-rich foods. Dairy products such as milk, yogurt, and cheese provide calcium to protect and build tooth enamel. You can also get calcium by eating green leafy vegetables, including bok choy, Brussels sprouts, and kale.
4. Use care when you bite down. This tip applies any time you apply force with your teeth. Be careful eating foods like nuts or peanut brittle or hard pretzels. And if you use your “teeth as tools” to rip, tear, or clamp down on things – stop it!
5. Wear a mouthguard for sports or workouts. Use a mouthguard when playing ANY sport where a collision or fall is possible. Mouthguards should also be worn during fitness activities such as rock climbing, hiking, or even cycling. To best avoid dental injury that could lead to a root canal, get your mouthguard professionally fitted.

“Chances of needing a root canal can be minimized with proper planning and the right habits,” says Dr. Susan L. Wood, an endodontist at Phoenix Endodontic Group. “Visit your dentist for regular checkups and cleanings, and always let them know if you experience any discomfort or symptoms indicating you need a root canal.”

The benefits of a root canal treatment when you have a tooth that is infected or injured are significant. First and foremost, you keep your tooth. Root canals also effectively reduce tooth pain, decrease the chance that serious dental infection will spread to adjacent teeth, and prevent the loss of bone density in the jaw, a common after-effect of tooth loss.

With all these advantages, the longer a root canal treatment can contribute to preserving a natural tooth, the better. The lifespan of a root canal treatment can vary considerably, depending on the circumstances. Here are several important factors that can play a role in how long your root canal treatment may last.

Factors Impacting Root Canal Success

1. Which tooth needs the root canal? The position of the compromised natural tooth will influence how complex the root canal procedure will be. Front teeth typically have only a single tooth root. Your molars, on the other hand, have two or even three root canals to be cleaned and filled, and will require a crown to protect the natural tooth afterward.

2. How bad is the damage to the tooth? Severe tooth decay or a crack or chip in a tooth can lead to inflammation or infection so bad that an abscess forms. If the outer structure of the tooth is still intact, there is a better chance that a root canal will last longer.

3. Who will perform the root canal? Endodontists are specialists in saving natural teeth. Surveys indicate that endodontists perform, on average, 25 root canals a week; general dentists average far fewer. One study found that 98 percent of root canals done by endodontists are successful, along with 90 percent done by general practitioners.

4. Will additional treatment be needed? The overall health of the tooth impacts whether a root canal is the best treatment. If the structure of the tooth itself is weak, a post and core procedure may be performed after the root canal to help anchor the crown and hold the natural tooth together.

5. Are you motivated to take care of your natural teeth? Patient involvement in the root canal process is critical to ensuring its long-term success. Contact your practitioner if you have unusual postoperative pain or if your temporary crown falls out; get the crown for the treated tooth promptly; and contact your dentist or endodontist if you have symptoms indicating tooth root infection at any point.

Dr. Susan L. Wood, who practices with the Phoenix Endodontic Group, says, “Root canals can preserve natural teeth for years or even decades – and for some, they can last a lifetime. Our practice can instruct you in all the ways you can ensure your root-canal treated tooth stays healthy for as long as possible.” 

It seems that our schedules continue to get busier these days and are full of activities that need to be accomplished, particularly this time of year. If you are dealing with the challenge of an infected or injured tooth, you may wonder if you really have to schedule a dental appointment to place a permanent crown over a tooth that’s been treated with a root canal. There’s so much else to do!

You may ask,“Can’t I wait until early next year to schedule my crown appointment?” The short answer to that question is NO. Here are a few reasons why you should schedule your follow up appointment to receive your crown within one to three weeks after your root canal.

Reasons Why You Should Not Delay Getting A Crown After Root Canal Treatment

1. A longer wait means a longer period of being extra careful. Many of the instructions you receive after your root canal – especially the ones related to eating soft, bland foods – are designed to protect the temporary crown. If you wait longer to get a crown, you will have to continue that regimen.
2. Until a final restoration (crown) is placed, your tooth remains at risk of further damage. A root canal-treated tooth can be more brittle after the procedure, and a permanent crown is needed to prevent future damage.
3. Your tooth may suffer extra sensitivity without a crown. Some teeth treated by root canals can become more sensitive to heat or cold. Permanent crowns reduce this effect.
4. The longer you wait, the more likely you are to have the temporary crown fall out. Your temporary crown is not secured to your tooth in the same way a permanent crown is. If it falls off, the chances that you will experience increased pain or reinfection can skyrocket, as can cost. Such situations often result in unplanned emergency trips to the dentist.
5. A permanent crown gives your natural tooth the best shot at long-term survival. A study published in the May 2020 Journal of Endodontics reported that natural teeth treated with a permanent crown restoration have a survival rate of more than 90 percent over nine years. The extra layer of outer protection provided by the crown safeguards the interior protection offered by the root canal.

“Having a root canal is the first step to rescuing a compromised natural tooth,” says Dr. Susan L. Wood, who practices with the Phoenix Endodontic Group. “Having a permanent crown placed over that tooth within one to three weeks ensures a much higher level of certainty that your tooth repair will last a lifetime.”

When you have a tooth that’s compromised by decay or injury, you need to move quickly to a treatment plan. You may also be suffering some significant pain, which can make it harder to think through your options.

It’s true that general dentists CAN do root canals, but often the best choice is to request a referral to an endodontist. Your general dentist probably has working relationships with several local endodontists, and they can suggest someone who is a good match for your scheduling and clinical needs.

Here are just a few of the many reasons why endodontists are the preferred provider for root canal treatments.

Why Should An Endodontist Do My Root Canal?

1. Endodontists receive several years of additional training. After graduating from dental school, endodontists receive two to three years of additional specialty training, treating diseases of the soft tissues of the teeth, including the nerve pulp.
2. Endodontists perform root canals more frequently than general dentists. The average general dentist performs fewer than two root canals a week; the average endodontist performs 25 per week. This means the endodontist will see a greater range of cases and have more experience in treating a variety of challenges that may emerge during the procedure.
3. Endodontists are trained to use leading-edge technology and microsurgical techniques. Advances in root canal treatment in recent decades have made the procedure successful in more than 90 percent of cases.
4. Endodontists frequently provide clinical consultations to general dentists on tough cases. General dentists, as noted earlier, often partner with nearby endodontists when they have patients who may need a root canal. This relationship means you can trust that the endodontic referral you receive was preceded by a clinical discussion of your specific needs and challenges.

“Root canals comprise most of an endodontist’s caseload – they are the most common treatment we deliver,” says Dr. Jacqueline S. Allen, who practices with the Phoenix Endodontic Group. “Patients can trust our years of specialized training, the techniques and equipment we have access to, as well as our relationships with local general dentists.”

If you’ve been referred to a Phoenix endodontist and have never seen one before, you might wonder what services they provide. Endodontics is recognized as an official specialty field for dentists by the American Dental Association. Endodontists attend two to three years of additional training after graduating from dental school. During their post-graduate training, they receive instruction in advanced microsurgical techniques and learn the latest in effective pain management methods.

Here’s a quick look at the types of procedures Phoenix Endodontic Group performs as part of their mission to save natural teeth whenever possible.

Procedures Performed By Phoenix Endodontists

1. Root canals and root canal retreatments. Root canals are frequently how patients first meet an endodontist. The procedure preserves natural teeth by cleaning infection out of a tooth’s root canal, and replacing the nerve pulp inside of a tooth with biocompatible material. A crown is placed over the treated tooth to protect it. Root canal retreatments can fix things that go wrong with an initial root canal, such as new decay entering the tooth or the tooth being further fractured.
2. Endodontic surgeries. Root canals, which are a non-surgical procedure, are typically very effective at treating a tooth threatened by infection or structural damage. Some cases require more intensive treatment. An apicoectomy is a surgery that treats damaged root surfaces or persistent infections in the bone surrounding the tooth. Recovery time for endodontic surgeries, just as for root canals, is usually brief. Postoperative discomfort is usually mild and easily remedied.
3. Dental trauma treatment. Your Phoenix endodontist can help save a damaged tooth, but you must act quickly. Regardless of the level of damage to a tooth – from a small chip or crack to a tooth that’s been knocked out of your mouth – you need a full examination of your teeth and gums to determine the next steps to be taken. An endodontist has equipment, dental training, and experience to preserve a damaged tooth; they can determine if a root canal or another procedure is the best one to protect and preserve the structure of your tooth.
4. Dental implants. More and more Phoenix endodontists are providing dental implant services for patients. The reasoning? All dentists receive training related to dental implants in dental school, with many endodontists receiving additional training in the placement of implants, as well. Endodontists are uniquely positioned to determine if a natural tooth can be saved. If a tooth cannot be saved, your endodontist can play a key role in the replacement of it.

“Phoenix Endodontic Group endodontists work closely with general dentists from across the Valley of the Sun to provide the best treatment results for all our patients,” says Dr. Susan L. Wood, of the Phoenix Endodontic Group. “Together, we can diagnose, collaborate, and treat dental challenges, so each patient experiences the most positive outcome for their case.”
