Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.
But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.
There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.
The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.
During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.
If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.
And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.

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.
If you've thought the ads for a “new tooth in one day” seemed too good to be true, we have…sort of good news. You can get a new “tooth” in one visit, but only if your dental situation allows it.
The restoration in question is a dental implant, a metal post (usually titanium) surgically imbedded into the jawbone. They're especially durable because bone cells naturally grow and adhere to an implant's titanium surface, a process called osseointegration. Over time this process creates a strong bond between implant and bone.
Usually, we allow a few weeks for the implant to fully integrate with the bone before attaching the visible crown. With “tooth in one day,” though, we attach a crown at the same time as we install the implant, albeit a temporary crown. It's more aesthetic than functional, designed to avoid biting forces that could damage the implant while it integrates with the bone. When that process finishes, we'll install a permanent porcelain crown.
The health of your supporting bone and other structures will largely determine whether or not you're a candidate for this “tooth in one day” procedure. Your bone must be sufficiently healthy, as well as the gums surrounding the implant and the tooth's bony socket.
If, on the other hand, you have significant bone loss, gum recession or socket damage, we may first need to deal with these, usually by grafting tissue to the affected areas to stimulate new growth. Your implant, much less a temporary crown, will likely have to wait until the affected tissues have healed.
The bone can also be healthy enough for implant placement, but might still need time to integrate with the implant before attaching any crown. Instead, we would suture the gums over the implant to protect it, then expose and attach a permanent crown to the implant a few weeks later.
Obtaining even a temporary crown the same day as your implant can do wonders for your appearance. A more important goal, though, is a new tooth that you can enjoy for many, many years. To achieve that may mean waiting a little longer for your new beautiful smile.

Losing a tooth can be traumatic, but a dental implant can dramatically turn that experience around. Providing functionality, life-like appearance and durability, implants stand out as the premier restoration for lost teeth.
For adults, that is. An older child or teenager with a missing tooth may need to wait a few more years for an implant. The reason: jaw development. A person's jaws, particular the upper jaw, continue to grow with most growth completed by early adulthood. Natural teeth with their periodontal attachments develop right alongside the jaw.
But because an implant attaches directly to the jawbone, its position is fixed: it won't change as the jaw grows and may gradually appear to sink below the gum line. That's why we wait to place an implant until most of jaw maturity has occurred after full jaw maturity. For females, we try to wait until 20 years of age and for males, usually 21 years of age. These are guidelines as some people mature faster and some slower, so a discussion with your dentist or surgeon is necessary to make an educated decision.
While we wait, we can install a temporary replacement for a child's or teenager's lost tooth, usually a partial denture or fixed modified ("Maryland") bridge. The latter affixes a prosthetic (false) tooth in the missing tooth space by attaching it to the back of natural teeth on either side with bonded dental material. It differs from a traditional bridge in that these supporting teeth aren't permanently altered and crowned to support the bridge.
During the time before implants we should understand that the area where the implant will be placed will undergo some bone deterioration, a common consequence of missing teeth. Forces generated as we chew travel through the teeth to stimulate renewing bone growth all along the jawbone. But with a lost tooth the chewing stimulation ceases at that part of the bone, slowing the growth rate and leading to gradual bone loss.
Fortunately, the titanium posts of dental implants stimulate bone growth as bone cells naturally grow and adhere to their surfaces. Before then, though, if the bone volume is diminished, we may need to graft bone material to stimulate bone growth that will enlarge the jaw bone enough for an implant to be placed.
It usually isn't a question of "if" but "when" we can provide your child with an implant for their missing tooth. In the meantime, we can prepare for that day with a temporary restoration.
