Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.
Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.
Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.
Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.
However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.
Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. After several months, we may have enough regenerated bone to support an implant.
If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.
For decades, dental x-rays have helped us accurately diagnose and treat a wide array of dental diseases and conditions. But even with recent advances in digital imaging, the traditional x-ray does have one drawback: its two-dimensional view doesn’t always provide the “big picture” that a three-dimensional viewpoint can provide.
But a new type of x-ray technology can do just that: known as cone beam computed tomography (CBCT), these machines record hundreds of digital images as a cone-shaped beam of x-ray energy is projected through a device that rotates around a person’s head. A computer then assembles the images into a single three-dimensional image that can be manipulated on screen to view from various angles. Not only does this provide greater context and detail, it does so with no more radiation exposure than a standard 20-film digital full-mouth x-ray series.
While CBCT hasn’t replaced the traditional x-ray, it’s making its mark in a number of specialized areas of dentistry. The following are just a few of the ways CBCT is improving both accuracy and treatment outcomes.
Orthodontics. CBCT can provide a much more detailed view of the entire jaw; this can help us determine the best locations for realigning teeth safely and effectively.
Dental Implants. With a CBCT scan we can precisely locate nerve canals, sinuses and adjacent teeth before implant surgery to locate the best position for the implant.
TMD Treatment. To help develop the best treatment approach for alleviating the pain and dysfunction of temporo-mandibular joint disease (TMD), a CBCT scan can provide us detailed information on how the disease is affecting a patient’s joints, teeth, sinuses and airway.
Impactions. An impacted tooth can exert damaging pressure against the roots of neighboring teeth. A CBCT scan allows us to observe the impacted tooth from various vantage points to determine the best treatment approach for neighboring teeth, nerve canals and sinuses.

With only a few teeth now showing in your baby’s mouth, you might think it’s too early to schedule their first dental visit. But you should, and here’s why: tooth decay.
Although adults are more likely to contend with dental disease, the exception for children is tooth decay. One kind of decay, early childhood caries (ECC), can wreak havoc in children’s primary teeth. While your child may or may not be at high risk for ECC, it’s better to err on the side of caution and begin regular checkups by their first birthday.
Since primary teeth eventually give way for permanent teeth, it may not seem that important to protect them from decay. But despite their short lifespan primary teeth can have a long-term effect on dental health for one primary reason: They’re placeholders for the permanent teeth that will eventually replace them.
If they’re lost prematurely to decay, nearby teeth can drift into the resulting open space. This can crowd out the intended permanent tooth, which may then erupt out of place (or not at all, remaining impacted within the gums). Protecting primary teeth from decay—or treating them if they do become infected—reduces this risk to the permanent teeth.
Besides regular cleanings, dentists can do other things to protect your child’s teeth from decay. Applying a high strength fluoride solution to teeth can help strengthen enamel against acid attack, the precursor to decay. Sealants on the biting surfaces of teeth deprive bacterial plaque of nooks and crannies to hide, especially in back molars and pre-molars.
You can also help prevent decay in your child’s primary teeth by starting a brushing regimen as soon as teeth start appearing. Also, limit sugar intake by restricting sugary foods to mealtime and not sending a child to bed with a sugary liquid-filled bottle (including juices or breast milk). And avoid possible transfers of oral bacteria from your mouth to theirs by not drinking from the same cup or placing any object in your mouth that might go in theirs.
Tooth decay can have long-term consequences on your child’s dental health. But by working together with your dentist you can help ensure this damaging disease doesn’t damage their teeth.
