For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
Are you interested in dental implants but a little hesitant about the surgery? Don’t be—this procedure to imbed an implant’s titanium post in the jawbone is relatively minor with little to no discomfort for most patients.
Some time before, however, we’ll need to pre-plan the surgery to pinpoint the best location for the implant, critical to achieving a solid hold and a life-like appearance. During these first visits we often create a surgical guide, a device inserted in the mouth during surgery that identifies the exact location for the hole (or channel) in the bone we’ll drill to insert the implant.
On surgery day, we’ll prepare you for a pain-free and relaxing experience. If you’re normally anxious about dental work, we may prescribe a sedative for you to take ahead of time. As we begin we’ll thoroughly numb the area with local anesthesia to ensure you won’t feel any pain.
The surgery begins with an incision through the gum tissue to access the underlying bone. Once it’s exposed, we’ll insert the surgical guide and begin a drilling sequence to gradually increase the size of the channel. This takes time because we want to avoid damaging the bone from overheating caused by friction.
Once we’ve created a channel that matches precisely the implant’s size and shape, we’ll remove the implant from its sterile packaging and immediately fit and secure it in the channel. We’ll then take x-rays to ensure it’s in the best position possible.
Satisfied we’ve properly situated and secured the implant, we’ll suture the gum tissue back in place to protect the implant with or without attaching a healing abutment to it as it fully integrates with the jawbone over the next few months (after which you’ll come back to receive your permanent crown). After a short recovery, you’ll return to full activity. Most patients only experience mild to moderate discomfort usually manageable with over-the-counter pain medication like aspirin or ibuprofen.
While implantation is a long process, you’ll be obtaining what’s considered by most dentists and their patients as the most durable and life-like tooth replacement available. Your new attractive smile will be well worth it.

There are good reasons, for both health and appearance, to replace a missing tooth with a dental implant or similar restoration as soon as is practical. The bone around a tooth socket diminishes the longer it remains empty, up to 25% the first year. And, of course, your smile is less attractive, especially with a highly visible tooth.
If it’s your teenager, though, you may need to wait on a permanent restoration because their jaws are still developing. An implant placed before completion of jaw development could eventually appear out of alignment with neighboring teeth.
Our biggest concern is protecting bone health at the site of the missing tooth. We can do this and encourage growth by placing bone grafts (processed minerals from another donor) that serve as scaffolds on which surrounding bone can grow. Grafts usually dissolve (resorb) over time, but the rate of resorption can be slowed for a younger patient in need of long-term bone growth.
Planned orthodontic treatment can usually go on as scheduled. The orthodontist may accommodate the tooth loss by adding a temporary tooth within the braces or other device that matches the color and shape of the patient’s natural teeth. The orthodontist will also take care to maintain the empty space for a future implant or other restoration.
A dental implant is considered the best option for a missing tooth, not only for its life-like appearance and durability, but also its ability to encourage bone maintenance. Timing, though, is essential for teenagers. As it grows, the upper jaw will tend to move forward and down. Natural teeth move with this growth; implants, though, are attached differently and won’t move with the jawbone. While the other teeth around them move, the implants can appear to shrink back resulting in an unattractive smile appearance. So waiting until the jaw has finished growing is important.
For most people, jaw growth finishes by age twenty-one for men, women usually faster, but each person is different. The dentist’s expertise and experience, coupled with comparisons of adult family members’ facial appearances, will help determine the right time to undertake a permanent restoration for the best outcome both for health and a permanent, attractive smile.

Dental implants are known for their durability as well as life-like beauty. Thanks to their unique construction and ability to integrate with bone, they have a very high success rate and can last for decades.
But while they’re less problematic than other restorations, we still can’t “set them and forget them.” While the implants themselves aren’t susceptible to disease, the supporting gums, bone and adjacent teeth are. If you want them to last as long as possible, you’ll need to care for them and the rest of your mouth through daily oral hygiene and semi-annual office cleanings.
With that said, there are a few differences in how we perform hygiene tasks with implants. This is due to the way in which they attach to the jaw, as the titanium post is inserted directly into the bone. Natural teeth, on the other hand, are held in place by the periodontal ligament, a strong connective tissue that lies between the teeth and bone. The ligament holds the teeth firmly in place while also allowing minute tooth movement in response to changes in the mouth.
The ligament also has an ample blood supply that assists with fighting infection that may arise in the tooth and its supporting gums. Without this extra source of defense, infections that arise around an implant can grow quickly into a condition known as peri-implantitis and lead to rapid bone loss that could cause the implant to fail.
That’s why you and your hygienist must be ever vigilant to the buildup of plaque, the bacterial film that gives rise to dental disease, around implants and adjacent teeth. This includes removing plaque buildup from implant surfaces, although your hygienist will use tools (scalers or curettes) made of plastic or resin rather than traditional metal to avoid scratching the implant’s dental material. They’ll likewise use nylon or plastic tips with ultrasonic equipment (which uses high vibration to loosen plaque) and lower power settings with water irrigation devices.
Keeping infection at bay with effective hygiene is the number one maintenance goal with dental implants. Doing your part along with your hygienist will help you get the most of this investment in your smile.

If you've lost a tooth or need to have one extracted, you have to decide how to replace it. Of all the options available none can match both the lifelikeness and function of a dental implant.
A dental implant is a prosthetic (false) tooth that mimics the root of a natural tooth. Once that implant root form fuses to the surrounding bone, we attach the crown, which is the part of the tooth you can see.
While other replacement options like bridges or dentures can restore the lifelikeness of the tooth crown, they don't replace the root. An implant's titanium post can: using a minor surgical procedure we imbed the post into the bone. Because bone cells have a natural affinity with titanium, they will grow around and adhere to the post over a few weeks after surgery. This further adds strength to the implant's hold in the bone.
Although the attachment isn't exactly like natural teeth, it can maintain this hold for many years. And because it encourages bone growth, a dental implant will help minimize bone loss, a natural consequence of losing teeth. Other replacement options can't do that.
Of course, implants are more costly than other restorations. With an attached crown, an implant can replace any number of teeth. But if you have extensive tooth loss, bridges or dentures would be more cost-effective selections.
But even then, implants could still play a role. We can strategically place a small number of implants as supports for a bridge or even a removable denture. Not only will the implants better secure their attachment, they'll also stimulate bone growth.
