Dr. Ian Jay Langer D.M.D.'s Expert Contributions
I let a cavity go way too far, and it's causing a lot of pain. What should I do?
Pain? Rotting tooth? See an endodontist for evaluation. Endodontists (root canal specialists) save teeth and eliminate pain. Pulling a tooth should be last resort if necessary. For your individual case, an exam is required to determine if the tooth can be saved or needs to be pulled. An endodontist deals with the tough cases all the time. If a general dentist says that the root canal is too difficult and cannot be done, again, see an endodontist who specializes in treating teeth that the general dentist cannot or is unable or unwilling to treat.

What are the signs of a failed root canal?
Failed root canal therapy may experience pain, swelling, tenderness biting, pressure sensitive on the gums, pus draining through the gums and breakdown READ MORE
Can a tooth affected by cavities be saved?
Depending on how much tooth has been destroyed or damaged, the tooth may be able to be saved, possibly with root canal therapy. You would have to have a dentist or ENDODONTIST (root canal specialist) examine and evaluate the tooth. No other specific recommendations can be made without an exam. Only a dentist who did the exam can tell. READ MORE
Is my tooth infection spreading?
It can be any number of things. The infection may be spreading, it may be referred pain, it may be an independent problem. You have to see your dentist or endodontist to evaluate it to make the correct diagnosis. READ MORE
Can a root canal have prolonged recovery?
You should clarify recovery. If you have pain when biting or chewing, you should check the bite and reduce it. That is the biggest complication I see and the easiest to correct. Often, the crown is off a little and your bite ever-so-slightly too hard on it. Not really noticeable at first. READ MORE
What can be the risks involved in an endodontic surgery?
There are risks associated with ALL surgery, that includes endodontic surgery. The usual risks include bleeding, bruising, nerve damage, unsuccessful outcome, pain, swelling, jaw fracture, sinus perforation, lost roots, poor healing and more. Depending on the location of the tooth/root, some problems may be more likely than others. Of course, the same risks occur with extractions, implants, periodontal surgery, etc. This is the main reason why I recommend re-treatment of the root canal rather than surgery as a first choice. Most endodontists are retreating root canals that did not respond to the original treatment rather than surgery. Re-treatment offers a higher success rate when performed by an endodontist compared to surgery on an infected root. If the tooth is properly cleaned out, then surgery success rates rise. Of course, re-treatment is usually more time consuming and will damage the crown, necessitating a new post and crown. Surgery is faster, but if it doesn't work, then what? READ MORE
How successful is an apicoectomy?
Apicoectomy is my 2nd choice of treatment. 1st choice is Re-treatment of the root canal. Last choice would be an implant. Endodontists are dentists who specialize in treating root canals and other pulpal problems. An endodontist should always be consulted if root canal therapy is failing or if you are told "it can't be treated," "too infected," "too complicated," "it won't work," etc. In my own practice, about 25% of the patients have come in because the root canals failed the first time when done by their general dentist. Endodontists offer a higher success rate. Endodontists have surgical microscopes and specialized training that most general dentists do not have. Please understand that general dentists treat approximately 90% of the root canals in the USA. Endodontists get the tougher ones. Endodontists can have failed root canals, but so can implants (they have the same success rates). If the root canal failed because of fracture, then extraction and implant would be advisable. Endodontists can usually spot fractures with the microscope and thus recommend extraction before you go through the whole process of root canal therapy, post and crown and then problem from the missed fracture. Apicoectomy has about 90% success on an uninfected canal, and 50% success on an infected canal. Re-treatment of the root canal offers about a 95% success rate. I feel it is always better to clean out the infection that is in the root canal rather than seal it into the root canal. READ MORE
What does endodontic retreatment involve?
It is essentially an endodontist (root canal specialist) re-doing the original root canal treatment. Usually done with a microscope for improved vision, the endodontist removed the post (if present) and removes the root canal fillings, basically undoing everything that was done originally. The endodontist would look for missed canals, fractures and whatever else would have caused the original treatment to fail. Retreatment is not easy, the canals are filled with a "permanent" filling which means that it is not easy to remove. It may often take several visits, and in extreme cases, sometimes the endodontist will recommend surgery if required. Surgery is never a first choice (at least in endodontic offices). Retreatment usually has a higher success rate than endodontic surgery, which is why it is recommended as a first choice. READ MORE
Endodontists and root canals?
Retreatment of a failed root canal is always more complicated. The endodontist has to go through crowns, remove posts and remove old root canal fillings. The post and root canal fillings are permanently cemented in...meaning not easy to remove. Canals may be blocked out, have broken instruments or be perforated. Problems to be undone. Endodontists use microscopes to enable them to see far better, which may make it easier, but not easy. READ MORE
Is a root canal treatment permanent?
When it comes to the human body, the only thing permanent is death. Root canal treatment, when performed by an endodontist, offers about a 90 - 95% success rate, by a general dentist, about 15 - 20% less. Generally, endodontics has a very high success rate similar to implants which are also about 90 - 95% successful. Extractions are 100% successful in that the tooth is gone and won't return, though there can be plenty of complications. Endodontist use microscopes that enable them to see far more clearly. Also, with 2 or more years of specialty training, they are better prepared to handle more complicated cases. Given a choice, I would usually prefer the root canal treatment by an endodontist and try to save my own tooth. If it fails, you can fall back on implants. If implants fail, then what? (Please note, the percentages are across large populations, individual dentists and patients may have different results). READ MORE
I have a cracked tooth. Does this expose me to an infection?
It may, depending on the location and extent of the fracture. If it penetrates into the root, you could lose the tooth. Have it checked out by your dentist ASAP. READ MORE
