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.

“Dear Dr, I’m 50 years old and my teeth are very sensitive with looseness, severe pain & falling out due to necrosis. I have big prob to chewing my diet pl advise me”

Answer:

What you are reporting are the sure signs of periodontal disease.  This involves losing the bone around teeth, as well as supporting structures, as a result of bad oral hygiene.

Your question actually sparked us to write a detailed article concerning periodontal disease.  For an in-depth explanation of periodontal disease, please follow the link here: http://www.savemysmile.com/dental-problems/periodontal-disease-dental-problems/periodontal-disease/

Good luck and we hope this helps!

The most common cause of loose and sensitive teeth is periodontal disease. Periodontal disease includes gingivitis (inflammation of the gums) and periodontitis (inflammation of the periodontium). The periodontium is the structure that surrounds the teeth and holds them in their sockets. Periodontal disease is an infection that can cause teeth to become loose and eventually lost.

Periodontal disease is most often caused by bacterial plaque that surrounds teeth. Bacterial plaque is a sticky film that continues to form around teeth. If it isn’t removed constantly, it can continually build up and form calculus (calculus is just a hardened form of bacterial plaque). There are a number of other causes of periodontal disease.

Causes of Periodontal Disease

• Smoking: smoking causes shrinkage of some blood vessels, hence the periodontium is affected by not having enough blood flow and oxygen. Smokers tend to lose teeth more than non-smokers, because of periodontal disease.
• Hormones: gum tissue are sometimes affected by hormonal changes, for example during pregnancy or menopause
• Genetics: some individuals are more prone to periodontal disease, despite proper oral hygiene practices, because of genetic factors. Early diagnosis and treatment may help to save teeth in such individuals.
• Diabetes: diabetics have a higher risk of developing infections, including periodontal disease. Healing is also slower with diabetes, making periodontal disease a greater concern with respect to oral health. Diabetes, though not the only reason, may be a cause of necrosis (tissue death due to lack of blood and oxygen).
• Poor Nutrition: a diet that is low in necessary nutrients affects the body, including the oral cavity. Periodontal disease is a distinct infection that may worsen with poor nutrition.

Treatment of Periodontal Disease

In many cases, an individual may have had long standing or severe periodontal disease, and some teeth (in other cases, all of the teeth) cannot be saved. In these cases, extractions may be the only viable option, with replacement of the missing teeth with implants, bridges or dentures. Other treatment options are available for treating periodontal disease, each option depending on individual cases/.

• Scaling and root planning: this involves professional cleaning of plaque and calculus from root surfaces and periodontal pockets. This is the most common method used to treat periodontal disease.
• Periodontal surgery: if the tissues around the teeth are determined to be unhealthy, periodontal surgery (there are more than one types) may be necessary to treat the periodontal disease. Periodontal surgery can help to improve function.
• Cosmetic methods: this can be done to improve a patient’s appearance, smile and function, if for example a lot of roots are exposed by the periodontal disease.

Each individual’s case of periodontal disease is different, so the necessary treatment may be different for each patient. An individual with a diagnosis of periodontal disease, especially long standing or advanced, can be treated by a periodontist (a dentist with specialized training in diagnosing, preventing and treating periodontal disease). You can be referred to a periodontist by a general dentist, or be treated by a general dentist. Please be pro-active in a consulting with your dentist for a comprehensive evaluation, diagnosis and treatment.

Last week,  I had 2 teeth taken out by the dentist.  But today, there was some type of bloody-white “ooze” coming out of the area where one of the teeth came out.  I haven’t had any pain, just the ooze.  Is this dry socket?

Answer:

From what your describing, it definitely isn’t dry socket.  Dry socket is quite painful and occurs when you’ve lost the blood clot in your tooth socket and the bone is exposed.  This sounds like an infection.  After an extraction, for the first couple of hours you can expect some bleeding and some slight pain.  The dentist should have prescribed pain pills and antibiotics so as to avoid an infection.  Depending on the severity of the infection now, the dentist may just prescribe some more antibiotics.  But please visit your dentist right away and tell him/her that you have an infection.

Good luck!
