What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.

On the way to adulthood, permanent teeth steadily erupt until, if all goes normally, you have a full set of teeth. Sometimes, though, one or more teeth may fail to form. This not only can affect your dental health, but it could also diminish your smile.
For example, if the lateral incisors on either side of the central incisors (the two teeth front and center) don't develop, it could create a smile that's “not quite right.” But we can vastly improve such a smile in one of three unique ways.
The first is to fill the resulting gap through canine substitution. This is an orthodontic method in which we use braces to move the pointed canine teeth, which normally position on the other side of the missing laterals, closer to the central incisors. This choice is determined by the size of the canine teeth. If they are slim in width, they can be re-shaped to make them appear more like a lateral incisor, and the gums possibly reshaped as well around them through cosmetic surgery.
We can also install a dental bridge, an appliance that fills the missing lateral space with prosthetic teeth. A traditional bridge requires the teeth on either side of the gap to be reduced in size, which becomes a permanent alteration to accommodate these crowns. This is a disadvantage in a young person. We can also use a “bonded bridge” which uses adhesives to attach extended pieces (or “wings”) of dental material from either side of the prosthetic tooth to one or more supporting teeth. These wings are behind the permanent teeth. Though not as durable as a traditional bridge, it does avoid altering the support teeth.
Finally, we can replace the missing teeth with dental implants. In this method, we install titanium metal posts into the jawbone at the missing tooth locations and then attach a life-like crown to each one. Implants may be more costly than other restorative methods and can take several months to complete. But they are life-like, highly durable, and don't require any alteration to other teeth. A disadvantage is that you should wait until at least 19 years of age to consider this option. What many people do is use a temporary solution until the proper age to do a dental implant.
Each of these methods have their advantages and disadvantages, which should be thoroughly reviewed in consultation with your dentist. And each may also require other dental work, such as initial orthodontics to open adequate space for a restoration. But any of these methods for correcting a missing lateral tooth can be effective and help restore both a healthier mouth and a more attractive smile.

There are plenty of good reasons to quit smoking. Here's one more if you're considering replacing a missing tooth with a dental implant: smoking increases your risk of implant failure.
By and large, dental implants are the most reliable and durable tooth replacement option, with more than a 95% success rate after ten years. But that still leaves a small percentage that fail — and twice as many of those failures are in smokers than in non-smokers.
To understand why, we need to look at how smoking affects oral health. Besides burning and thickening the surface skin cells inside the mouth, inhaled smoke can also damage salivary glands and lead to dry mouth. Reduced saliva creates an environment friendly to bacteria, which increases the risk of infection and disease.
The nicotine in tobacco also restricts the myriad of blood vessels that course through the teeth and gums. The resulting reduced blood flow deprives teeth and gums not only of nutrients but disease-fighting antibodies. The mouth takes longer to heal and can't fight infection as well.
The key to an implant's success lies with its titanium post imbedded in the jaw bone to take the place of the tooth root. Titanium attracts bone cells, which grow and adhere to the post over a period of time and create a stronger hold. But the health effects of smoking inhibit this process. Furthermore, slower healing caused by smoking increases the risk of infection, the number one cause of early implant loss.
If you want to improve your chances for a successful implant — not to mention improve your overall health — you should quit smoking. The prospect of a dental implant could be a useful incentive to enroll in a smoking cessation program.
At the very least we suggest you stop smoking a week before implant surgery and then for at least two weeks after to help promote good healing. And you should pay close attention to your daily oral hygiene — brushing and flossing at least once — and regular, semi-annual dental visits for cleanings and checkups.
Smoking can harm your health. If you're considering an implant, it could also harm your chances of a successful outcome.

Nothing beats the form and function of a real tooth—but dental implants come pretty close. That's why they're tops among both dentists and patients for replacing missing teeth.
Much of an implant's functionality and durability can be credited to its material construction, from the titanium metal post imbedded in the jawbone to the lifelike porcelain crown attached at its other end. But an implant's “nuts and bolts” isn't the only reason why this premier dental restoration is so popular: A good portion of their success comes from the adjunct support provided by digital technology.
Without this varied array of computer-based applications used in planning, designing and installing them, implants couldn't produce the level of satisfactory outcomes they currently do. Here then are a few of the high-tech tools dentists use to make sure your implants result in a winning smile.
CBCT scanning. Implant placement requires a high degree of precision often complicated by various anatomical structures like nerves, blood vessels and sinuses within the gums and jaws. Cone Beam Computer Tomography (CBCT) scanners rotate around a patient's head, taking hundreds of digital x-ray images that are then assembled into a 3-D model image. Dentists can view this model from various angles to identify obstacles and better pinpoint the best implant locations.
Digital impressions. Dentists can also create a 3-D digital impression model of the inside of a patient's mouth that can give them views of their current teeth and gums from any angle. This aids in determining the size and type of implant so that it blends seamlessly with remaining teeth. A digital impression can also provide both the dentist and patient a preview appearance of their future smile after treatment.
3-D printed surgical guides. To accurately drill the implant site during surgery, dentists often create a custom-made device called a surgical guide that fits into the patient's mouth during the procedure. Using results from scanning and digital impressions, highly accurate guides can be created with a 3-D printer. This further ensures that the implant will be in the exact best location for the most attractive and functional outcome.
Implantology is as much art as it is science in achieving a beautiful smile. These and other digital tools help make that desirable end a reality.

Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.
