For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.
This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.
In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.
One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.
If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

Gum disease is a bigger problem than you might think. More than half of all adults over age 30 have it, and that figure jumps to 70% of adults over 65. If left untreated, gum (periodontal) disease can eventually loosen teeth and cause them to fall out. It can also cause health issues outside of the mouth, including an increased risk of heart disease and other systemic health conditions.
But the good news is that gum disease can be treated—and even better, prevented! Since September is National Gum Care Month, it’s a good time to answer some frequently asked questions about gum disease:
What causes gum disease?
Gum disease is caused by certain types of harmful oral bacteria that live in a sticky film called dental plaque that collects on teeth both above and below the gum line. If this film is not cleaned effectively each day, it can eventually harden into a substance called tartar that can only be removed by a dental professional. As your body tries to fight the bacteria and the toxins they produce, your gums can become inflamed and may start to pull away from the teeth. Eventually, bone beneath the gums can start to break down and with continued bone loss, the teeth could be lost.
How do I know if I have it?
Gum disease doesn’t always produce symptoms—especially in smokers. Smoking hides the symptoms of gum disease because nicotine reduces blood flow to the area. However, there are things you should look out for. Gingivitis, a mild form of gum disease, can produce red and/or puffy gums that bleed when you brush or floss. Signs of periodontitis, a more serious form of the disease, include gum recession, bad mouth odors or tastes, and tooth looseness. But the only way to truly know if you have gum disease is to come in for an exam.
What can I do about it?
If you have gingivitis, a professional teeth cleaning and a renewed commitment to oral hygiene at home—including daily flossing and rinsing with antibacterial mouthwash—may be all you need to turn the situation around. Periodontitis may require a variety of treatments, ranging from special cleaning procedures of the tooth root surfaces to gum surgery. The first step toward controlling gum disease is visiting the dental office for an exam.
How can I prevent it?
Regular professional teeth cleanings and meticulous oral hygiene at home are your best defenses against gum disease. Avoid sugary drinks and snacks—which feed the disease-causing bacteria in your mouth—and tobacco in all forms. If you have diabetes, do your best to manage it well because uncontrolled diabetes can worsen periodontal disease.
A loose permanent tooth is not a good thing—and not something you should put off having examined. That’s because a loose tooth could soon become a lost tooth.
How we treat it depends on its underlying cause, which could be one of two types. One is primary occlusal trauma, meaning the affected tooth has experienced accidental trauma or higher biting forces than it normally encounters. This usually happens because of teeth grinding habits.
It could also be secondary occlusal trauma. Unlike primary trauma where the supporting gums and bone may be reasonably healthy, secondary trauma occurs because these structures have been severely damaged by periodontal (gum) disease. As the gums begin to detach from a tooth and its underlying bone deteriorates, even normal biting forces can loosen it.
If gum disease is present, our first priority is to bring it under control. We do this primarily by removing all dental plaque (a thin film of bacteria and food particles that triggers the infection and sustains it) and calculus or tartar (calcified plaque). This can take several sessions and, in the case of deep infection, may require a surgical procedure.
On the other hand, if teeth grinding is the primary cause, we’ll focus on minimizing the habit and its effects. One way is to create a custom-fitted guard worn to prevent upper and lower teeth from making solid contact. You may also need to improve your management of stress—another factor in teeth grinding—through medication, therapy or biofeedback.
In either case, improved periodontal health will help the gums naturally regain their strong attachment with help, if necessary, from gum tissue or bone grafting surgery. But this healing process can take time, so we may need to secure a loose tooth in the interim by splinting it to neighboring stable teeth. This usually requires bonding rigid material or metal across the back of all involved teeth or in a channel cut along the teeth’s biting surfaces. In this way the more stable teeth support the loose one.
Splinting may be temporary as the mouth heals from disease or trauma and the teeth regain their stability. In some cases, though, it may be permanent. Either way, dealing promptly with a loose tooth can help ensure it’ll survive—so see your dentist as soon as possible.
