Complete tooth loss is a common condition among older adults, gradually occurring one or two teeth at a time. There often comes a point of realization, though, that all the teeth will eventually be lost.
This can create a dilemma: Do you replace teeth as they're lost, or go ahead and have all of them removed at one time?
Up until recently, the latter choice seemed the most practical and affordable. But most dentists would agree that keeping natural teeth for as long as practical is better for a person's overall oral health and to slow any potential bone loss.
The emergence of dental implants has made this less of a dilemma: We can use this technology to more affordably replace teeth in stages rather than all at once. This is because an implant is technically a root replacement: a dentist inserts a titanium metal post into the jawbone. Because of an affinity with titanium, bone cells grow and adhere to the implant surface, which creates a stronger hold. It also impedes bone loss.
We can, of course, use implants as individual tooth replacements. But the expense of this approach with multiple teeth puts it well out of reach financially for many people. But implants can also be used as connective points between the patient's jaw and other kinds of dental restorations like bridges, partial dentures, and full removable or fixed dentures.
Using this approach, we can adopt a strategy of allowing healthier teeth to remain until it's necessary to remove them. We initially place implants to support a bridge, for example; later we can use the same implants along with additional ones to support a larger restoration, even a fixed full denture.
An implant-supported restoration is typically more expensive than traditional bridges or dentures, but far less than replacing teeth with individual implants. And because the stages of restorations may occur over a long period of time, the cost can be spread out to make it more manageable.
If you're facing a future where it's likely you'll lose all your teeth, you don't have to lose them all at once. Staged restorations with implants could help you hold on to your natural teeth for as long as possible, slow bone loss and make for a healthier mouth.

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.
Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.
That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.
That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.
When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.
If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.
Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.
To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.
