My Answers

Is my tooth infection spreading?
It is possible that the infection is spreading, but a more likely explanation is either referred pain coming from the back tooth, or there is a separate, independent issue with that tooth. I can't determine that just from the information you provide. You should visit an endodontist to take X-rays and pulp testing on the teeth in question. READ MORE
Can a root canal have prolonged recovery?
There is not enough information to determine whether this is normal or if there is something wrong with your root canal. In general, it is possible for the tooth to feel a little achy or tender for 6-12 months after a root canal. Sometimes there is little to no discomfort immediately after the procedure. On the other hand, there could be some reason causing your symptoms, and it is impossible to speculate what it could be without more information. You should contact the dentist who did the root canal and asked to have it checked. READ MORE
How successful is an apicoectomy?
More information regarding the specific tooth in question is needed in order to give an accurate estimate of the success rate. Basically, the better the condition of the tooth and it's surrounding bone and soft tissue, the better the prognosis. In other words, if there remaining tooth structure is compromised, or if the gums and/or bone around the tooth are not healthy, an apicoectomy may not be enough to solve the problem. However, if there is plenty of healthy tooth structure remaining and the periodontal support for the tooth is good, an apicoectomy should have a good prognosis. An implant is an alternative to saving your natural tooth, and is sometimes a good and the better option. However, generally speaking, it is better to try and save the natural tooth if at all possible, so the implant should really be a last resort when the natural tooth is not salvageable. READ MORE
What can be the risks involved in an endodontic surgery?
The main risk of endodontic surgery is that it may not be successful every time. However, there are other secondary risks that you should be aware of. There is the possibility of infection, pain, excessive bleeding, paresthesia (temporary or semi-permanent nerve damage), gum recession, bone loss, scarring of the soft tissue, etc. The chances of any of the above happening are small, but you should be aware that there is a small possibility of these risks, as is the case with any procedure.

One of my front teeth just chipped. How will this be fixed?
Without more information and a clinical exam, it is impossible to determine for sure. It depends on how big the chip is. If it's really small, it might just need to be shaped and smoothed off. If a medium amount chipped off, it will probably need to be bonded with some composite resin. If a large amount chipped off, it may need a veneer or a crown. And finally, if it chipped off close to or into the nerve of the tooth, it may need a root canal, then a crown. READ MORE
What does endodontic retreatment involve?
An endodontic retreatment is done on a tooth that already has a previous root canal. First, your mom will be anesthesized locally, a rubber dam will be placed over her tooth, then the old filling material will be removed, the canal re-cleansed and shaped, and refilled. This procedure should be done only by an endodontist. READ MORE
Endodontists and root canals?
All dentists are trained to do root canals in regular dental school, and general dentists can and are qualified to do them. An endodontist is a dentist that has gone to school for an additional 2-3 years to study the biology and mechanical techniques of root canal and related procedures, and are more qualified to perform root canals that might be more challenging. READ MORE
Is a root canal treatment permanent?
Root canal procedures have about a 90% success rate and can last many years. However, many factors determine whether a root canal will need to be retreated in the future. First of all, the root canal itself should be done properly to aid in a successful result. Secondly, the tooth must be sealed and properly restored after the root canal. And finally, the patient has to take responsibility for taking good care of the tooth after the root canal and permanent restoration. If all three of these factors are positive, then there is a high chance that your root canal will last for many years. READ MORE
How often should I get my teeth cleaned from a dentist?
You should get your teeth cleaned and also checked by your dentist at least twice per year. READ MORE
I am bleeding after 6 hours of my tooth extraction. What should I do?
Pain that soon after a tooth extraction is not necessarily abnormal. Bleeding depends on the level of bleeding. If it is just a gradual oozing of blood light bleeding, that is relatively normal and you should be able to control it by applying direct pressure to the extraction site with some sterile gauze. If it is a active flow of blood that cannot be stopped, you should contact the doctor who extracted your tooth immediately and ask for advice. If you are unable to reach your doctor, you should visit an emergency room. READ MORE
I have a cracked tooth. Does this expose me to an infection?
It depends on how deep the crack is. If it is shallow or just on the surface, infection is unlikely to be an issue. However, if it is deep, it is possible that bacteria and other contaminants can infiltrate down through the crack and eventually lead to an infection READ MORE
