Bad news at your last dental visit: You have a decayed tooth. And not just in the enamel—the decay has invaded the tooth's inner pulp and the resulting infection is threatening the supporting bone structure.
You're thinking that tooth is toast. Then comes the good news: your dentist believes the tooth can be rescued with a root canal treatment.
But then you begin thinking about how often Uncle Sid says he'd rather undergo a colonoscopy than have a root canal. Is the procedure really as painful and uncomfortable as popular culture says it is? What is a root canal really like?
First step: Things go numb. Uncle Sid is wrong: A root canal treatment is painless because your dentist will first make sure the entire area involving the tooth is anesthetized. This does involve injecting the local anesthetic deep within the tissues, but you won't even feel the needle prick thanks to topical anesthesia applied to the surface gums.
Second step: Drilling deep. After applying a protective dam to isolate the infected tooth from its neighbors, your dentist will drill a small access hole through the enamel and dentin to reach the pulp and root canals. If it's one of the larger back teeth, the access hole is usually drilled in the tooth's biting surface; in a front tooth, the hole is usually located on the tongue side.
Third Step: Removing diseased tissue. Using special instruments, your dentist will remove the diseased tissue in the pulp and root canals, essentially stopping the infection and any tooth pain you've been experiencing. The empty pulp chamber and canals are often then disinfected with a special antibacterial solution.
Fourth Step: Protecting the tooth. After some shaping, the pulp chamber and root canals are filled with a special filling to prevent further infection. The access hole is then filled and sealed to complete the procedure. At some point in the future, the tooth typically will need a crown to add support and further protection.
You may have some minor discomfort afterward, but this can usually be managed with a mild pain reliever like ibuprofen or acetaminophen. After a week or so, you'll be good as new—and so will your tooth.

Primary (baby) teeth don't last long. But despite their short life span, they do a number of important things, like enabling a child to eat solid food. But perhaps their most important long-term function is “paving” the way for their permanent replacements.
If one is lost prematurely, though, the permanent tooth might not come in properly aligned. That's why if a primary tooth is in danger of loss due to decay or injury, we'll do our best to save it.
But that could get a little tricky if the infected or damaged part of the tooth is the innermost pulp. If it were an adult tooth, the best course might be a root canal treatment: access the pulp, clear out the diseased tissue, and then fill the space with a special filling. But with a primary tooth (or a young permanent tooth for that matter) that may not be advisable.
That's because the pulp plays a more important role in a child's tooth than an adult's. Its nerves and other tissues stimulate dentin growth; a full root canal could disrupt that growth and weaken the tooth in the long run.
With a child's tooth, we proceed carefully depending on how infected or damaged the pulp might be. If it's only slightly exposed or not at all, we try then to remove as much decayed tooth material outside the pulp as necessary, then apply antibacterial agents or dentin growth stimulators.
If we do have pulp exposure, we'll try to remove only as much of the affected pulp as necessary through a procedure called a pulpotomy. This technique will only be used if the remaining pulp looks healthy or restorable to health.
If not, we may need to perform a pulpectomy to remove the entire pulp. Most like a typical root canal, it's a last resort: without the pulp, dentin growth could be stunted and the tooth won't develop as healthy as it should.
Of course, the best approach is to prevent teeth from developing such problems in the first place. So, be sure to practice effective daily hygiene with your child and keep up regular dental visits beginning at age one.

Along with the gums, your teeth’s roots help stabilize them. Without them your teeth couldn’t handle the normal biting forces you encounter every day. That’s why a rare condition called root resorption must be treated promptly: this gradual breakdown and dissolving of root structure could eventually cause you to lose your tooth.
Resorption is normal in primary (“baby”) teeth giving way for permanent teeth or sometimes during orthodontic treatment. But the form of resorption we’re referring to in permanent teeth isn’t normal, and is highly destructive.
The condition begins in most cases outside the tooth and works its way in, usually at the gum line around the cervical or “neck-like” region of the tooth (hence the term external cervical resorption or ECR). ECR produces pink spots on the teeth in its early stages: these are spots of weakened enamel filled with pink-colored cells that cause the actual damage. The cells create cavity-like areas that can continue to enlarge.
We don’t fully understand what causes ECR, but there seems to be links with excessive force during orthodontics, tooth trauma (especially to the gum ligaments), tooth grinding habits or internal bleaching procedures. However, most people with these problems don’t develop ECR, so the exact mechanism remains a bit of a mystery.
The good news, though, is that we can treat ECR effectively, provided we discover it before it inflicts too much damage. That’s why regular dental visits are important, coupled with your own observation of anything out of the ordinary and immediate dental follow-up.
If the affected area is relatively small, we may be able to remove the cells causing the damage and repair the area with a tooth-colored filling. If it appears the pulp (the tooth’s innermost layer) is involved, we may need to perform a root canal treatment to remove infected tissue and fill the empty space with a special filling. You may also need other procedures to reduce the chances of gum recession around the affected tooth.
Proactive dental care is your best insurance against losing a tooth to root resorption. So keep an eye on your teeth and see your dentist regularly to keep your teeth and gums healthy.

A cracked, infected, or extensively decayed tooth is bound to fail. To avoid extraction, your dentist in Matthews, NC, Dr. David Feeney, may recommend restoration through root canal therapy. Read on to learn how this effective treatment can end up saving your smile!
What is root canal therapy?
Root canal therapy—also called endodontic therapy—is a procedure that removes the damged interior pulp of a diseased or decayed tooth. This compromised pulp contains a blood supply, connective tissue, and nerves, but fortunately, a mature tooth survives well without it.
Here at our Matthews, NC, office, your dentist cleans, disinfects, and seals each root canal with an elastic substance called gutta-percha. Afterward, he covers the restored tooth with a temporary cap to protect it as it heals. Following a recovery period of about 10 days, the patient receives a beautiful porcelain crown to preserve and support the tooth for life.
What tells your dentist you need a root canal?
His careful examination of your tooth, X-rays and a review of your symptoms tell your dentist you need root canal treatment. Your symptoms may include:
- Toothache pain (often severe and throbbing)
- Dental sensitivity to sugary foods or hot or cold drinks
- Reddened, swollen gums
- Sores on the gums
- Extensive decay
- Deep crack or chip
- Bad breath and drainage, indicative of a dental abscess
What happens after your root canal
After you receive your permanent crown, floss around the tooth, and brush twice-a-day to keep crown margins free of plaque and tartar. Additionally, make sure to avoid hard foods, such as peanut brittle, so you don't dislodge or damage your newly restored tooth.
Animated-Teeth.com states that root canal therapy usually lasts indefinitely. Therefore, it's a great way for you to keep your tooth strong and your smile free of unattractive and dysfunctional gaps.
If you have worrisome dental symptoms, don't delay. Call Dr. Feeney's office in Matthews, NC, for an appointment and see if you need a root canal. Phone us today at (704) 847-1000.
It’s absolutely critical to stop tooth decay and repair any damage to tooth structure. Hopefully, we’ve caught it early in the enamel and dentin where we’re able to repair any holes or “cavities” that might have developed by filling them.
But what if the decay has crept deeper into the interior of the tooth? In this case, you’re at a much higher risk of eventually losing the tooth. If the decay has spread into the bone, a root canal treatment is usually your best option.
The first sign that decay has invaded the pulp, the innermost layer of the tooth, and the root canals may be a severe toothache. It’s different from the wince of pain or discomfort caused by sensitivity to temperature or pressure. Inner decay pain is constant and often excruciating. This is because the infection is attacking the nerves bundled within the pulp chamber.
The pain can last for several days, and then suddenly stop altogether. No pain is good news, right? Wrong — the pain has stopped because the infected nerves have finally died and can no longer signal the brain. The infection, though, is very much alive and will continue to advance toward the root where the damage may eventually cause you to lose the tooth.
A root canal treatment removes decay in the pulp chamber and canals. We first drill an access hole to enter the pulp chamber. Once inside, we use special instruments to completely remove all tissue and disinfect the empty chamber. We then fill the chamber and root canals with a special filling and seal the access hole to prevent further decay. A few weeks later we install a custom crown to protect the tooth further.
If you have a toothache, or you’ve had one that suddenly went away, you should schedule an appointment for a dental examination as soon as possible: this is the only way to accurately determine the cause of the pain. If a root canal is deemed necessary, the sooner we perform it, the less chance the infection will cause you to lose your tooth.
