The “magic” behind a dental implant’s durability is the special affinity its imbedded titanium post has with bone. Over time bone grows and attaches to the titanium surface to produce a strong and secure hold.
But there’s one important prerequisite for ultimate implant success—there must be an adequate amount of bone available initially to properly position the post during implantation. Otherwise, the implant may not have enough support to position it properly or cover the implant surface completely with bone.
Inadequate bone can be a problem for patients who lost teeth some time before and now desire to an implant restoration. This happens because when teeth are missing, so are the forces they generate during chewing. These forces stimulate new bone growth around the tooth root to replace older, dissolved bone at a healthy rate. If that replacement rate is too slow, the volume and density of bone may gradually diminish.
There is a way, though, to build up the bone for future implantation. Known as bone preservation procedure or a ridge augmentation, it’s a surgical procedure in which the dentist adds bone grafting material to the extraction socket or the bony ridge. The graft serves as a scaffold for new bone cells to grow and multiply. If successful, there will be enough new bone volume after several months of healing to support proper implant placement.
Bone grafting can add more time to the implant process. It may also mean you will not be able to undergo immediate crown placement after implantation (a “tooth in one day” procedure). Instead we would probably suture gum tissue over the implant to protect it and allow for full integration with the bone over a few more months. In the meantime, though, we could fit you with a temporary restoration like a removable partial denture (RPD) or a bonded bridge to improve the appearance of the space while the bone continues to heal.
After several months, your implant will have a better chance of a secure hold and we can then attach a life-like crown. Even if you’ve suffered bone loss, you’ll then have the benefit of not only a durable implant but also a new smile.
Periodontal disease may start in the gums’ superficial layers, but it’s not likely to stay there. As the disease moves deeper it can wreak havoc on tooth roots and bone as well as gum tissue attachments. Teeth with multiple roots are in particular peril because of the “forks” called furcations that form where the roots separate from each other. Infected furcations can be very difficult to treat.
We primarily treat gum disease by removing its main source, a thin film of bacteria and food particles called dental plaque that builds up on teeth. To remove it we most often use special hand tools or ultrasonic equipment to vibrate it loose. As the plaque and tartar diminish, the infection begins to wane.
But we can’t be completely successful in stopping the disease if any lingering plaque deposits remain. This especially includes furcations where the infection can cause significant damage to the roots. Although cleaning furcations of plaque can be difficult, it’s not impossible with the aforementioned tools and antimicrobial substances to disinfect the area.
The real problem, though, is access—effectively getting to the furcations to treat them. We may need to perform a surgical procedure called flap surgery where we create a hinged flap in the gum tissue to move it aside and access the root area beneath. Afterward we replace the flap and suture the tissue back in place.
In some cases, the infection may have already caused significant damage to the tissue and underlying bone. We may therefore need to graft gum or bone tissues to these damaged areas to stimulate re-growth. We may also need to surgically reshape the gum attachments around a tooth to make it easier in the future to access and clean the area.
These additional treatments around furcations can be very involved and labor-intensive. That’s why the best outcomes occur if we’re able to start treatment in the early stages of an infection. So, if you notice red, swollen or bleeding gums contact your dentist as soon as possible. Treating gum disease as early as possible will help ensure your tooth roots won’t suffer extensive damage.

If you're suffering from jaw pain or impaired function, it may not be the only source of chronic pain in your body. Of the millions of adults with temporomandibular joint disorders (TMD), many have also been diagnosed — among other conditions — with fibromyalgia, rheumatoid arthritis or sleep problems.
TMD is actually a group of painful disorders that affect the jaw joints, muscles and surrounding tissues. Besides pain, other symptoms include popping, clicking or grating sounds during jaw movement and a restricted range of motion for the lower jaw. Although we can't yet pinpoint a definite cause, TMD is closely associated with stress, grinding and clenching habits or injury.
It's not yet clear about the possible connections between TMD and other systemic conditions. But roughly two-thirds of those diagnosed with TMD also report three or more related health conditions. Debilitating pain and joint impairment seem to be the common thread among them all. The similarities warrant further research in hopes of new treatment options for each of them.
As for TMD, current treatment options break down into two basic categories: a traditional, conservative approach and a more interventional one. Of the first category, at least 90% of individuals find relief from treatments like thermal therapy (like alternating hot and cold compresses to the jaw), physical therapy, medication or mouth guards to reduce teeth clenching.
The alternative approach, surgery, seeks to correct problems with the jaw joints and supporting muscles. The results, however, have been mixed: in one recent survey a little more than a third of TMD patients who underwent surgery saw any improvement; what's more alarming, just under half believed their condition worsened after surgery.
With that in mind, most dentists recommend the first approach initially for TMD. Only if those therapies don't provide satisfactory relief or the case is extreme, would we then consider surgery. It's also advisable for you to seek a second opinion if you're presented with a surgical option.
Hopefully, further research into the connections between TMD and other inflammatory diseases may yield future therapies. The results could help you enjoy a more pain-free life as well as a healthy mouth.
