Why Do Some Root Canal Treatments Fail?

And Why It Isn’t Your Dentist’s Fault

Root canals aren’t usually people’s favourite procedures. If you have to have one, it means that you’ve probably been in pain or discomfort for a while and have made a trip to an after hours dentist. After all that trouble, you probably think that the root canal should solve everything. But sometimes, your problems will continue after the root canal, meaning that you have to get further treatments. If this happens to you, then you need to know why it happens and why it isn’t always your dentist’s fault.

Why Do You Need a Root Canal?

In basic terms, people need a root canal when the pulp or inside of their tooth has become infected. During a root canal, the nerve and pulp inside your tooth are cleared out and the area is sealed so that bacteria can’t get in there again. To complete the procedure, your dentist will usually put a crown over the top of the tooth to increase its strength and repair its appearance. This procedure usually alleviates any pain immediately because the nerve, the part of your tooth that registers pain, is gone. And once the area has healed, you will be able to go back to your normal eating routine and probably won’t even notice that you ever had the procedure done.

If you have an infected tooth, your dentist will usually try to treat the infection with antibiotics first. However, if the infection has gone too far, if it threatens the health of surrounding tissue, it’s usually better to perform a root canal. Otherwise it can cause problems such as abscesses or pain and infection in other parts of the face and even in the rest of the body.

Some causes of tooth pulp infection include:

• A cavity that has been left too long.

• A crack or chip that hasn’t been repaired and has let bacteria into the centre of the tooth.

• Repeated procedures on a tooth.

• Gum infections that have been left untreated and infected a tooth.

• Face traumas.

What if the Root Canal Doesn’t Work?

Most people who get a root canal go back to their normal lives without any further problems. In fact, between 90 and 95 percent of root canals are completely successful. However, there are a small percentage of people who aren’t so lucky.  

There can be a number of reasons why a root canal may fail. And the first and most common is related to the original infection. As Doctor Oberoi from Emergency Dentist Sydney says about root canals, “If they haven’t been done properly in the first place and the infection is still there they can fail.” That’s why you need to make sure that your root canal is done by a properly qualified and experienced after hours dentist.

Another reason why a root canal may fail has to do with the condition of the tooth itself. Doctor Oberoi points out, “…if there’s a crack in the tooth then it can affect the root canal. That’s why we usually recommend putting a crown over the tooth.”

A root canal may also fail if it isn’t taken care of after the procedure. You need to make sure that you follow your dentist’s instructions closely when it comes to after care. Otherwise the gum or surrounding teeth could become infected, resulting in more dental work.

Our Top 5 Emergency Treatments

The Biggest Threats to Your Oral Health After Hours

If you have a problem with your teeth at night or on the weekends, you’ll probably need to see our after-hours dentist. This is more common than you think. It’s normal to want to avoid thinking about a niggling pain in your tooth for as long as possible. But unfortunately, this means that it can flare up just at the wrong time. When this happens you’ll need to see a dentist as soon as possible. At our Emergency Dentist in Sydney, we see all sorts of dental problems after hours, but there are some that are more common than others. To learn about these procedures, and their treatments, keep reading.

1. Extractions

If you have a tooth that’s too damaged to fix then you may need an extraction. This type of damage is usually caused by injury or decay.  During an extraction the affected tooth is removed from the socket bone. If the tooth is clearly visible in the mouth, your dentist will loosen it and then remove it with forceps. However, if the tooth is broken off below the gum line or hasn’t come through the gum then it will have to be removed surgically. This is a more complicated procedure during which the gum is opened up to remove the offending tooth.

2. Root Canal Treatment

If you have an infection or inflammation in a tooth then you may need a root canal. This is a very common reason for trips to the after-hours dentist and causes a great deal of pain and discomfort. Tooth infections happen by deep decay, a chip or crack in the tooth, or previous dental surgeries.

If you need to have a root canal your dentist will remove all the infected pulp from inside the tooth. The whole area will be cleaned and sterilised to remove all traces of the infection before a filling is inserted into the tooth to replace the tooth pulp. This procedure can save the affected tooth and help you avoid further surgeries.

3. Fillings & Dental Bonding

If you have a hole in your tooth because of decay, then you’ll probably need a filling. This is a very common procedure and an easy way to alleviate the pain that can occur with decay. During a filling procedure, your dentist will remove the damaged section of the tooth and replace it with a filling. A filling can be made of a number of different types of material depending on the size of the hole and its position in your mouth.

Another common emergency procedure is dental bonding. This is the cheapest and quickest way to improve the appearance of a damaged, broken or decayed tooth. The bonding material is attached to the surface of the tooth and vastly improves its appearance. During this procedure, your dentist will lightly abrade the surface of the affected tooth, apply a conditioning liquid and attach the resin. This is like plastic, so it can be moulded to fit the shape of your tooth. The material is smoothed and then hardened using an ultraviolet light.
 

4. Wisdom Teeth

Wisdom teeth usually grow in the late teens or early twenties. Unfortunately, not everyone has enough room in their mouth for these extra teeth. If this is the case for you, the new wisdom teeth can push other teeth out of the way or become impacted, causing infection and pain. This can come on quite suddenly and result in a trip to the after-hours dentist.

At the dentist, you will need to have an exam to determine what the problem is and what has to be done to alleviate it. If there isn’t enough room for your wisdom teeth, you will probably need to have them taken out. However, wisdom teeth can also cause pain in the gums and jaw when they’re coming through. So even if they hurt, you won’t necessarily have to have them removed. That’s why it’s important to get them checked so you can plan your next step.
 

5. Re-cementing of Crowns, Veneers & Bridges

Crowns, veneers and bridges are all used to replace missing or damaged teeth. Crowns are used to encase an entire tooth. They’re most often used when the tooth is decayed or damaged and improve the strength and the appearance of the tooth. Veneers cover the front side of the tooth, the part that faces outward, and improve the appearance of a damaged or broken tooth. And finally, a bridge is an artificial tooth that’s attached to surrounding teeth.

Despite the strength and durability of these dental additions, they can sometimes become damaged or loose. This can occur when the procedure is fairly recent and hasn’t completely set yet, because of injury, or while you’re eating something hard. If you lose a crown, veneer or bridge, your dentist will need to evaluate the area to see if the original addition can be re-applied. If not, you will have to decide what step to take next. If the dental addition can be reapplied your dentist will clean your mouth and the implant and reattach it.

Tooth Extractions

You Have Nothing to be Afraid of

You might have chipped a tooth from a fall or cracked a tooth from accidently biting down on something hard. Whatever the reason for your toothache or pain, a tooth extraction will most likely not be the first procedure your dentist will suggest. Tooth extractions are actually only done as a last resort. However, if you are in a situation where your tooth needs extracting, there is totally nothing to fear!

Tooth Extraction is the Last Resort

Dental treatments and techniques are rapidly advancing. At Emergency Dentist Sydney, our dentists will always discuss with you the right treatment options for your dental emergency.  We avoid tooth extraction as there are a number of treatments that can be done first instead and most importantly, we want to save your tooth. This means if you have a broken tooth and are avoiding the dentist because you're fearing the extraction procedure, call your dentist now as an extraction may not be the case. Your dentist will try to fix your damaged tooth with a filling, crown or other treatment. 

The Extraction Procedure

Sometimes, there may be too much damage for the tooth to be repaired. This is when the tooth will need to be extracted. The Procedure itself is fairly quick. Dr. Oberoi states that it usually takes under a minute to actually remove the tooth. He says that “I spend more time talking to the patient and making sure they’re comfortable than doing the procedure itself.” The care at Emergency Dentist Sydney is personalised to the patient, to ensure the procedure is as comfortable and stress free as possible.

A Painless Dentist Procedure

What we will always do is make sure that the area we are performing the extraction is completely numb. Even administering the anaesthetic is painless with the help of some numbing cream. At Emergency Dentist Sydney, we also have a number of options for anxious patients including local anaesthesia, happy gas or even IV sedation. Your dentist will discuss with you the best option for your situation and condition.

Tooth Extraction After-Care

Aftercare is almost as important as the extraction itself. Your dentist will stay in touch with you over the days after the procedure. They will be able to answer any questions or concerns you might have and provide assistance in the unlikely case of complications.
