- 07/15/12Read MoreDental PostsOnce root canal treatment has been performed then the tooth must be restored. Root canals are usually performed on teeth that are quite broken down and therefore must be built up to have enough tooth structure available to hold onto a crown. In order to retain the core buildup, many times a post must be placed inside the root canal. This is done by removing a portion of the root canal filling material (the part closest to the tip of the root is left to seal the end) and drilling out the proper size to accept the post (no need to worry about the drilling — remember there is no nerve in a root canal tooth). Then, the dentist chooses one of two types — a cast post and core or a prefabricated post. The cast post and core has advantages in that the core buildup is made as one piece with the post so there is no way for the two to separate. A disadvantage is that it must be fabricated outside of the mouth and therefore cannot be cemented on the same day, however, other provisions must be made to build up the tooth. Some prefabricated posts are metal and some of the newer ones are made of carbon fiber composite. The newer carbon fiber ones have a little bit of give to them and they look promising on possibly reducing root fractures in teeth with posts.Read More

Removing all organic deposits is tantamount in allowing for a good final seal. Any left over pieces of debris will contaminate the filling material and cause it to leak and fail prematurely. An irrigating solution is important to not only help flush debris from the canal during the cleaning process, but to also provide final disinfection of the canal before it is filled. Sodium hypochlorite, the main ingredient in common household bleach, makes an ideal irrigating solution. It will emulsify living tissue so that it can easily be flushed from the canals. This is especially important when working in canals that have lots of nooks and crannies for vital and non-vital tissues to hide. When an oxygenating agent is added it will bubble out hiding debris that cannot be mechanically removed with the thin files that the dentist uses to clean and shape the canals. It is important that the irrigant stay within the confines of the root canal space so as to not cause peripheral tissue damage. Once the irrigant has done its job, it is dried up with points of absorbent paper, but it still has the residual effect of disinfection before the root canals are filled.Read More

Even the best fitting denture available can fall victim to a sore spot. It’s a nature of the beast. Dentures are constructed to sit on movable tissue. When an impression of the gums is taken, every effort is made to move the tissue wherever possible to compensate for the problem. But there is no way to predict exactly how the tissue will move during function. Once the denture has been placed and the wearer chews food, the gum tissue will move against the hard plastic. If there is an area of the plastic that impinges on the tissue, then an area of chronic irritation will occur.
This area eventually ulcerates leaving behind a very painful area. If you have a denture sore, it is a very easy thing to correct. Make an appointment with your dentist and make sure that you wear the denture for 24 hours before your appointment. This way, the dentist can see the exact area of irritation and relieve a very small portion of the denture to alleviate the problem. If the area is too tender to wear for that 24 hour period, then go to the pharmacy and get an oral anesthetic such as Orabase with benzocaine and place it on the sore spot. Removing the dentures before the appointment allows the body to have time to heal the wound then the dentist would be only guessing as to where the problem is. One final word on denture sores — any denture sore that does not disappear after adjustments or non-wear of the denture should be biopsied to rule out malignancy.Read More

It’s a common perception that once a root canal has been done, there will never have to be anything else to do for that tooth. While that is true with most root canals, there is an occasional one that is not successful.
The most common reason is not being able to get a good seal on the root. Any leakage around the root canal filling material can allow bacteria to filter in. Since there are no blood vessels in the area (those were removed by the root canal process), there will be no way to get antibodies and white blood cells to the area. This way, the bacteria can proliferate causing an infection. The only way to correct this problem is to retreat the root canal. That is done by opening up the tooth, then softening and removing the gutta percha filling material. After that is done, it’s a good time to search for extra canals or unusual root anatomy. All of the canals are cleaned thoroughly and irrigated with sodium hypochlorite. At this point, a decision is made on whether to place medication in the tooth and allow it to heal for a week or two or to go ahead and fill it that day. Retreatments do not enjoy the same success rate as original root canals, but they work often enough that they are sure worth giving a try.Read More
- 07/15/12Read MoreAbfractionNo — abfraction has nothing to do with those pesky arithmetic problems that we solved in school. It is a phenomenon that happens along the cervical area of a tooth. The cervical area is along the gum line. An abfraction lesion is a “V” shaped notch in the tooth that forms along the gum line. It was previously thought that these cavitations were caused by overly aggressive tooth brushing or by leeching out through chemical erosion, it is now postulated that forces of the bite will cause the tooth to flex causing tiny cracks to form over the years eventually forming the classic “V” furrow. There are no studies at this time which prove beyond a shadow of a doubt that these wedge formations were caused by biting forces, however, it comes the closest to explaining a phenomenon that can’t be caused by tooth brushing alone. These cavitations can be observed for a while, but they should be restored before they get too deep. By rounding out the “V” shaped notch during the cavity preparation, biting forces will be more evenly distributed, helping to slow the process. Due to tooth flexion during chewing, fillings placed in these areas tend to need to be replaced more often.Read More
- 07/15/12Read MoreSleep ApneaSleep apnea can be a potentially life threatening condition. Unlike simple snoring, a sufferer of sleep apnea will stop breathing for as much as a minute to a minute and a half. This can happen many times during the night. As a result, the person will awaken in order to restart the breathing process. This causes sleep deprivation leading to lack of alertness and drowsiness during the day. It is important that cases of sleep apnea be diagnosed by a physician. If there is airway obstruction, many times, surgical procedures can be performed to alleviate the problem.
A C-PAP (continuous positive airway pressure) machine may be prescribed. A specially fitted nosepiece is worn at night during sleep. It helps to keep the airway open, prevent snoring, and stops interruptions in breathing. There are some sufferers who can be helped with oral appliances that bring the mandible (lower jaw) forward, helping to open the airway. It can be helpful for those who have difficulty wearing a C-PAP machine at night. A physician should make the decision as to whether to try the oral appliance or not. If so, our office can construct an appliance to see if it alleviates the problem.Read More
