Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

You have a lot of options for replacing missing teeth, from state-of-the-art dental implants to affordable, but effective partial dentures. But if the teeth in question have been missing for a while, you may first have to undergo orthodontic treatment. Here's why.
While they may feel rigid and firm in the jawbone, teeth are actually held in place by periodontal (gum) ligaments. These elastic tissues lie between the teeth and the bone and attach to both with tiny filaments. This mechanism allows the teeth to incrementally move over time in response to biting pressures or other environmental factors.
When a tooth goes missing the teeth on either side of the space naturally move or "drift" into it to help close the gap. This natural occurrence can reduce the space for a restoration if it has gone on for some time. To make room for a new prosthetic (false) tooth, we may have to move the drifted teeth back to where they belong.
If you're thinking metal braces, that is an option—but not the only one. Clear aligners are another way to move teeth if the bite problem (malocclusion) isn't too severe. Aligners are a series of custom-made, clear, plastic trays worn over the teeth. The patient wears each tray, slightly smaller than the previous one in the series, for about two weeks before changing to the next one. The reduction in size gradually moves teeth to their intended target position.
Many adults prefer clear aligners because they're nearly invisible and don't stand out like metal braces. They're removable, so you can take them out for cleaning or for special occasions. And, we can also attach a prosthetic tooth to the tray that temporarily covers the missing tooth space.
Whichever orthodontic treatment you choose, once completed we can then proceed with restoration to permanently replace your missing teeth. While it can be a long process, the end result is a beautiful smile that could last for years to come.

When it comes to replacing a missing tooth, you have several options, including a removable partial denture or a fixed bridge. But the premier choice is “the new kid on the block” at just over thirty years old: dental implants. Implants are by far the most popular tooth replacement choice among both patients and dentists.
But they also happen to be the most expensive option, at least initially. So the question is, why invest in dental implants over less costly choices?
Here are 3 reasons why implants could be well worth their price.
More Like a real tooth than other restorations. Implants can match the life-like appearance of any other replacement choice, often utilizing the same types of materials. But where they really excel is in function—how they perform while biting and chewing. This is because the dental implant’s titanium post imbedded in the jawbone replaces the tooth root. No other dental restoration can do that—or perform better when comparing the resulting functionality.
Best long-term solution. As we mentioned before, the initial implant cost is typically higher than either dentures or bridges. But you should also consider their durability compared to other choices. It could be potentially much longer—possibly decades. This is because the titanium post creates an ultra-strong hold in the jawbone as bone cells naturally grow and adhere to this particular metal. The resulting hold can withstand the daily forces generated during eating and chewing. With proper care they might even last a lifetime, and actually cost you less in the long run over other choices.
Adaptable to other types of restoration. Implants have greater uses other than as individual tooth replacements. A few strategically placed implants can also be used to support removable dentures or a fixed bridge for multiple teeth or an entire dental arch. As the technology continues to advance, implants are helping to make other restoration options stronger, more stable and longer lasting—and adding more value to your investment.

Dental implants are considered the best tooth replacement option available. An implant replaces the root of a tooth and allows for the replacement of the crown via attachments or abutments. They not only look like a real tooth, they function like one too.
Implants, though, for some are a significant investment and may be well beyond a person's financial means if they've experienced a sudden tooth loss. For that reason, many opt for a less expensive tooth replacement option like a removable partial denture.
Later when they can afford it, a person might consider an implant. But this could pose a complication. When a tooth is missing for some time, the underlying bone doesn't rejuvenate normally because it no longer receives stimulation from the tooth. Over time, the amount of bone may diminish. Restorations like dentures can't stop this bone loss and actually aggravates it.
For proper positioning, an implant requires a certain amount of bone volume. So, it's quite possible when the time comes to replace the old restoration with an implant that there may not be enough bone available.
We may be able to overcome this bone loss with bone grafting and regeneration. A specialist such as a periodontist or oral surgeon accesses the area surgically and inserts bone graft material, usually processed material that's completely safe. Properly placed, the bone graft serves as a scaffold that, along with growth stimulators, encourages bone cells to grow.
When the bone grafting has healed enough, we're then able to place the implant. Once imbedded in the bone, one of the implant's unique qualities comes into play. The imbedded post is made of the metal titanium, which is not only bio-compatible with body tissues, it also has an affinity with bone. Bone cells will easily grow and adhere to the implant surface. This further boosts bone growth in the area and strengthens the implant's hold.
These extra procedures to build back lost bone do add to the cost and time for installing an implant. But if you're ready for a more permanent restoration for a missing tooth — not to mention better bone health — the extra time and money will be well worth it.
