Teeth-replacing dental implants not only look life-like, they’re made to last. For one thing, the metals and dental materials used in them are impervious to bacterial infection.
But that doesn’t mean implants are impervious to failure. Implants depend on the bone and other natural mouth structures for support. If the bone becomes weakened due to disease, the implant could become unstable and ultimately fail.
Peri-implantitis, the condition that can lead to this kind of failure, is a major concern for implant longevity. It’s a type of periodontal (gum) disease triggered by plaque, a thin film of food particles that can build up quickly in the absence of adequate brushing and flossing. The gum tissues around the implant become infected and inflamed.
If the infection isn’t properly treated with renewed oral hygiene and clinical plaque removal, it could spread below the gum line and begin to damage the underlying gum tissues and bone. This could destroy the all-important connection between the titanium implant post and the bone. The implant could eventually loosen and become completely detached from the bone.
The key is early intervention before the bone becomes damaged. Besides plaque removal we may also need to apply antibiotics in some form to control the growth of disease-causing bacteria. If the disease has fairly advanced we may also need to consider surgical repair to strengthen the attachment between implant and bone.
You can help to avoid peri-implantitis altogether by practicing consistent daily brushing and flossing around all your teeth including the implant, and seeing your dentist at least twice a year for cleanings and checkups. And by all means see your dentist if you notice any signs of gum swelling, redness or bleeding. Staying on top of your gum health will help not only the natural tissues and remaining teeth in your mouth, it will help preserve your implants for decades to come.
A root canal treatment is a commonly known but often misunderstood procedure. Contrary to popular belief, these treatments aren't painful — in fact, they often stop a toothache. More importantly, a “root canal” can give a tooth on the verge of loss another lease on life.
Still, if you've never experienced a root canal treatment before, you probably have questions. Here are the answers to a few of the most common.
Why do they call it a “root canal”? This is the popular shorthand term for a procedure that removes diseased tissue from a decay-infected pulp, the innermost part of a tooth and the actual root canals themselves. Root canals are the narrow, hollow channels that run from the tip of the root to the pulp and are also involved in the procedure.
Why do I need one? Once infected, the pulp's bundles of blood vessels, nerves and other tissues become diseased. This often results in a painful toothache that can also suddenly disappear once the nerves within the pulp die. But there's still a problem: If we don't clean out the diseased and dead pulp tissue, the infection could spread through the root canals to the bone and endanger the tooth's survival.
What happens during the procedure? After deadening the tooth and surrounding gums with local anesthesia, we enter the pulp through an access hole we create. Using special instruments we remove the diseased tissue and shape the root canals to seal them with a filling material called gutta percha. Sealing the access hole is then necessary to prevent re-infection. Later we'll cap the tooth with a porcelain crown to restore its appearance and add further protection against fracture or cracking of the tooth.
Who can perform a root canal treatment? In many cases a general dentist can perform the procedure. There are some complex situations, however, that require a root canal specialist with additional training, expertise and equipment to handle these more difficult cases. If your tooth is just such a case it's more than likely your general dentist will refer you to an endodontist to make sure you get the right kind of care to save it.

There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.
