What is a pulpotomy

Question:

“I have a tooth where i would like to save the portion not damaged by bacteria.  i am only being presented an option of root canal. can i opt to have a pulpotomy — usually this is only for <16.
I would like to preserve my radicular pulp/ dentin. (not symptomatic)”

Answer:

Pulpotomies are usually just a temporary fix.  More often than not, once bacteria reaches the pulp tissue, there’s no sure sign of judging the extent of it’s invasion.

Pulpotomies are oftentimes performed on primary teeth, or in emergency situations on adult teeth to alleviate extreme pain.  If it is a primary tooth, then we would encourage you to pursue the pulpotomy option.  However, if this is a permanent tooth, and you elect to have the pulpotomy, there is a chance that symptoms will return later on (anywhere from 1 week later to 1 year later).

In a situation like yours, it’s best to remove the entire pulp tissue, thoroughly disinfect and sterilize the canals, and fill with a therapeutic material to ensure the bacteria will not return.  We encourage you to have a root canal, but in the end, the decision is entirely yours.  The article below will detail decay, pulptomies, pulpectomies, and full root canal treatment.  We hope this helps you in your decision.

What is Tooth Decay?

Tooth decay (also called caries or cavities), is a very common and preventable oral disease. Basically, it happens when naturally occurring bacteria in the mouth produce acids after interacting with food (especially carbohydrates) left on teeth. This eventually wears away teeth over time if not treated. The type of treatment necessary after bacteria have caused damage to teeth depends on the extent of the decay. These include:

• Dental filling (this involves removing the decay and replacing the lost tooth structure with amalgam or dental composite material).
• If the decay has been long-standing and has compromised an extensive amount of tooth structure, an extraction may be recommended. The missing tooth or teeth may be replaced by a dental implant, dental bridge or removable partial denture as necessary and recommended by a dentist.
• Tooth decay may be extensive enough to cause a dental.  A dental abscess is serious enough to warrant immediate treatment.
• If the decay has extended to the pulp, a root canal treatment may be necessary

What is Root Canal Treatment?

After a root canal therapy, a crown (also known as a cap) is usually placed over the tooth to protect it. This is necessary because the canal(s) have been cleaned and filled, and the tooth is more susceptible to fracture (it’s more brittle). The canals formerly contained the blood and nerve supply for the tooth, which nourished and maintained the tooth.

What is a Pulpotomy?

A pulpotomy is a type of root canal treatment procedure that is usually performed on primary teeth. It involves the removal of the tissue from the pulp chamber of tooth. Pulpotomies are necessary if the pulp has been violated, either by decay or a tooth fracture. Pulpotomies are different from the root canal treatment done on permanent (adult) teeth in that only a part of the pulp is removed. A pulpotomy procedure may be recommended for a few reasons, including:

• Pulpotomy in children may prevent unnecessary loss of teeth due to a possible infection (the procedure is therefore preventative).
• Pulpotomies may be recommended to save the tooth, hence the space needed for adult (permanent) teeth to erupt.
• A pulpotomy procedure may give a developing permanent tooth a chance to fully develop, after which a conventional root canal therapy is done. This is called apexogenesis.

The success of the procedure depends on the extent of the decay and the patient’s own immune system.

What is a Pulpectomy?

More often than not, if the aim is to prevent the early loss of baby teeth, all of the pulp may be removed from the tooth. This procedure is called a pulpectomy. A pulpectomy procedure may be recommended in the following instances:

• When a tooth has a deep decay.
• When a tooth is fractured, causing exposure of or damage to the pulp.
• Where there is large dental filling.

Whether or not the tooth is symptomatic is a part of assessment that a dentist uses to diagnose the tooth’s condition. If the tooth is asymptomatic with a large decay extending into the pulp, this may be a necrotic pulp (meaning the pulp tissue is dead). Pulp necrosis is one sign that a tooth will need a root canal treatment.

Pain in tooth after root canal

Question:

“I have two root canals one on my upper left and the other on my upper right.  I have experienced episodes of pain in both since having the procedures done ~5 yrs ago. The most recent episode was a continuous sort of throbbing pain that persisted for three days before I decided to go to my dentist.  Each time one of these pain episodes occur my dentist takes x-rays and pokes around but is unable to provide an explanation and prescribes antibiotics.  A few days after taking the antibiotics the pain has dulled and goes away.  I no longer feel that this is an effective method in dealing with a persistent problem.  Antibiotics are discontinuing the pain, antibiotics attack and eliminate bacteria, so bacteria are a likely culprit to causing the pain.  Is a pain causing but not so severe bacterial infection able to be seen in an x-ray?  Should I request that my dentist remove the crown for a more thorough examination or is episodes of pain treated by antibiotics a part of the territory of living with a root canal? Lastly, am I supposed to even feel anything being that the pulp tissue is removed?”

Answer:

To specifically address your question, if the problem is alleviated by antibiotics, that’s a sure sign that there is a bacterial re-contamination.  This can be caused by a number of reasons that are outlined in our older article, called Failed Root Canal.  However, it is not normal for you to be feeling pain 5 years after a root canal.  The purpose of a root canal is to completely remove the source of infection, thus removing the source of pain.  It sounds like there may have been a missed canal (lateral canal, or a small canal at the apex), or a leaky crown, but the bacteria has found some kind of way to reinvade and re-infect the area.  It may be best to visit an Endodontist to have him/her reassess your tooth.  The Endodontist specializes in only root canals and has the technology to more closely examine your tooth condition.  Below we have detailed information regarding root canals.

What is a Root Canal Treatment?

A root canal treatment (also called root canal therapy) is a procedure that is done in order to attempt to save a tooth, usually after it has become badly decayed or infected. If the affected tooth is not treated, the infection or decay will usually spread to the tissues surrounding the tooth, including the bone.

Does a root canal hurt?

In most cases, the procedure is not painful, though there may be some sensitivity afterwards. Most cases of discomfort are felt if there was pain before the procedure (it goes away as the tooth heals), or if there is any complication such as a missed canal. One of the wonderful things about a root canal treatment is that the source of the pain is removed, the canal(s) thoroughly cleaned and disinfected, and the canals filled to prevent re-invasion of bacteria. Many patients retain their root canal treated teeth for life.

It’s important to note too that in most cases where there is discomfort after, the source is not in the tooth itself but in the periodontal ligament (PDL) surrounding the tooth. The infection in the tooth often spreads to the PDL (and in some cases the bone), which by itself is the cause of much sensitivity and discomfort.

What to do after a root canal

The root canal procedure has a success rate ranging between 68-95%. It is a welcome procedure for patients who have the opportunity to try and save their tooth or teeth. After the procedure is completed, a few things to know and expect:

• If there was tooth pain or an infection before the procedure, you may have some sensitivity for a few days after. This is because the tooth is healing from the tooth inflammation that was present before. Your dentist will most likely prescribe NSAIDs for the pain and inflammation. Antibiotics are used to treat oral bacterial infections, in cases where a tooth or teeth may have developed an infection.
• Avoid chewing on the tooth being treated until a permanent crown is placed. This will help you to avoid damaging or re-contaminating the tooth.
• Ensure that you complete the procedure by having a crown (cap) placed over the tooth. This helps protect the tooth from being exposed again to bacteria, and provides structural support and protection for a tooth that is no longer as strong on its own.

Pain years after root canal

Though not very common, there can be root canal pain years later. Reasons for pain after a root canal procedure include:

• Tooth fracture.
• A failed dental restoration (usually a crown) that has allowed bacteria to invade the tooth, causing a re-infection.
• The material sealed inside the canal(s) break down, allowing bacteria to recontaminate the tooth.
• Missed canal – not all canals were located, cleansed, and sealed during the procedure

Failed root canal

After root canal pain, a dentist will re-examine the tooth including the crown to determine the condition of the tooth and what needs to be done. It is sometimes tricky to isolate the problem, but two common approaches to relieving the recurrence of inflammation and infection include:

• A root canal retreat. Re-treatment is sometimes successful, and involves thoroughly cleaning and refilling the canals.
• Endodontic surgery may be needed in other cases. The most common endodontic surgery used to attempt to treat this is an apicoectomy (also called root-end resection or root resection). Basically, the tip of the root and the infected tissue around the root tip are removed. A small filling may be placed at the root tip to seal the root canal.

In extreme circumstances, the tooth may be non-restorable and will need to be extracted. Comprehensive evaluation is necessary for diagnosis and treatment of each patient’s case. Depending on the extent of the infection, changes are sometimes seen on a dental radiograph (dental x-ray) that indicate the presence of an active infection.

Pulpitis: Reversible pulpitis vs Irreversible pulpitis

Question:

“What procedure is done to fix reversible pulpitis”

Answer:

Causes of Tooth Pain

Whether it’s on and off, lingering or thumping, tooth pain is really uncomfortable and sometimes makes it hard to do anything else while the pain persists. Tooth pain causes are outlined in the article. Brushing at least twice a day and flossing daily, along with regular dental visits, are sure ways to prevent tooth decay (cavities). The modified bass technique is an effective brushing technique.

What is Pulpitis?

Pulpitis is an inflammation of the dental pulp. It’s primarily caused by bacteria that enter the pulp. The bacterial infection itself begins with tooth decay. Pulpitis may also be caused by any other type of injury to the pulp. Symptoms of pulpitis range from very mild to very severe. There are two types, and the pulpal diagnosis of each differs based of factors explained below.

What is Reversible Pulpitis?

This means that the tooth inflammation can be reversed, and the tooth symptoms relieved. The tooth therefore has a chance to heal and recover. The inflammation is usually secondary to decay, but may also be due to pulpal injury. Reversible pulpitis symptoms include:

• Tooth discomfort from contact with anything cold or another stimulus.
• Tooth symptoms that are relieved when cold or other stimulus is removed.
• Symptoms that gradually get better.
• Usually the discomfort experienced can be relieved by over the counter pain medications.

Treatment for Reversible Pulpitis

If a tooth has caries (tooth decay) and symptoms of reversible pulpitis, a dentist will remove the decay and replace the lost tooth structure with a dental filling. This reversible pulpitis treatment is usually sufficient to reverse the process. The symptoms normally improve over time, gradually disappearing.

What is Irreversible Pulpitis?

When the pulp tissue (nerve of the tooth) is damaged beyond recovery, this is known as irreversible pulpitis. The pulp will eventually die, and if the tooth isn’t treated soon enough, a tooth abscess (tooth infection) may occur.

A tooth vitality test is often done to confirm a diagnosis of irreversible pulpitis. The usual treatment of irreversible pulpitis is a root canal therapy. This is necessary in order to save the tooth. Irreversible pulpitis symptoms include:

• Spontaneous pain (pain that arises without any provocation). Tooth pain that wakes you up in the middle of the night is usually a sure sign of irreversible pulpitis.
• If the pain is brought on by a stimulus, it usually lingers even after the stimulus is removed.
• The symptoms generally get worse.
• Root canal treatment is usually necessary to treat the problem.

Pain after Root Canal

Question:

“I just had a root canal treatment in the top tooth, 5th from the middle. It’s been a month since the treatment, and I am having slight pain, it feels slightly loose.  What would you suggest for me to keep my tooth”

Answer:

What is Root Canal Treatment?

A root canal specifically refers to the space inside of the root of a tooth. A tooth may have one or more canals, just as they may have one or more roots.  Root canal treatment (also called root canal therapy or endodontic therapy) involves cleaning out the canal(s), disinfecting the canal(s) and then filling the canal(s).

Why do I need Root Canal Treatment?

Reasons why a root canal treatment may be recommended include:

• Tooth decay that has extended to the pulp
• Exposure of the pulp due to some trauma (this sometimes happens during rigorous sporting activities)
• A tooth that has become infected from decay (known as an abscessed tooth). Sometimes the infection may spread the bone surrounding the tooth.
• Internal resorption

Why does my root canal hurt?

There may be some sensitivity after the procedure, as the tooth heals. Pain after a root canal is not uncommon, though most patients may have no symptoms after treatment. In cases where there is associated pain, some reasons include:

• The associated pain is normal, as the inflammation slowly goes away and the tooth heals.
• There is an extra (much smaller) canal that may still need to be cleaned and filled. Teeth can be weird in this way (extra canals), and even the very best dentist can miss these hidden canals. This is usually corrected by the dentist or endodontist (a dentist who specializes in root canal treatment).
• The pain may actually be originating from the periodontal ligament surrounding the tooth.
• The root canal has failed, and a re-treat or endodontic surgery (also called root canal surgery) may be needed. If there is a dental infection at the root apex (tip), then an apicoectomy (which just means root tip removal) may be necessary.
• The tooth could have been fractures or perforated during the procedure.  Performing a root canal places a lot of pressure on the tooth.  Sometimes, if the tooth is weakened, it may fracture.  This could very well be the cause of your pain and looseness of the tooth.

Remember that each patient’s case is different, so diagnosing and treating depends on individual cases. Please see your dentist as soon as possible for evaluation to determine necessary treatment.

My tooth hurts when I eat hot or cold food or drinks

Question:

My tooth hurts whenever I eat hot or cold food or drinks.  If feels like a sharp pain, then it goes away.  What does this mean?

Answer:

This is a sure sign of a condition called reversible pulpitis.

What is Reversible Pulpitis

Reversible pulpitis essentially means that the nerve is starting to feel irritated, however it’s still fairly early and the sensation can easily be reversed by a dentist.

Exposed Dentin Causes Pain

The feeling that you are experiencing is caused by exposed dentin.  Remember that dentin is normally covered by enamel (see article on tooth anatomy), if for some reason a portion of dentin is left uncovered, you will usually feel sensations of short, sharp pain when exposed to hot or cold substances.  Exposed dentin can be caused by a cavity, a defective filling/restoration, or recent dental work.

Reversible Pulpitis Solution

The good news is that this problem can be fixed easily, the dentin just needs to be covered.  Your dentist will be able to give you a filling, simply fix your existing filling, or a pulp cap if necessary.  However, don’t wait too long.  Reversible pulpitis, if left untreated, can turn into irreversible pulpitis.  Unfortunately, irreversible pulpitis can only be treated with root canal therapy, which costs a lot more in the end.  So be sure to act now by visiting your dentist.

Good luck!
