Dental implants are widely considered the most durable tooth replacement option, thanks in part to how they attach to the jaw. But durable doesn't mean indestructible — you must take care of them.
Implants have a unique relationship to the jawbone compared to other restorations. We imbed a slender titanium post into the bone as a substitute for a natural tooth root. Because bone has a special affinity with the metal, it grows to and adheres to the implant to create a secure anchor. This unique attachment gives implants quite an advantage over other restorations.
It isn't superior, however, to the natural attachment of real teeth, especially in one respect: it can't match a natural attachment's infection-fighting ability. A connective tissue attachment made up of collagen fibers are attached to the tooth root protecting the underlying bone. An elastic gum tissue called the periodontal ligament lies between the tooth root and the bone and attaches to both with tiny collagen fibers. These attachments create a network of blood vessels that supply nutrients and infection-fighting agents to the bone and surrounding gum tissue.
Implants don't have this connective tissue or ligament attachment or its benefits. Of course, the implants are made of inorganic material that can't be damaged by bacterial infection. However, the gums and bone that surround them are: and because these natural tissues don't have these same biologic barriers to infection and perhaps access to the same degree of antibodies as those around natural teeth, an infection known as peri-implantitis specific to implants can develop and progress.
It's therefore just as important for you to continue brushing and flossing to remove bacterial plaque that causes infection to protect the gums and bone around your implants. You should also keep up regular office cleanings and checkups. In fact, we take special care with implants when cleaning them by using instruments that won't scratch their highly polished surfaces. Such a scratch, even a microscopic one, could attract and harbor bacteria.
There's no doubt dental implants are an excellent long-term solution for restoring your smile and mouth function. You can help extend that longevity by caring for them just as if they're your natural teeth.

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.
If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.

If you’re thinking about getting dental implants, you’re in good company. Dentists have placed more than 3 million of these popular devices since their introduction in the early 1980s.
But if you have multiple missing teeth, you might think the cost of all those individual implants could put them out of your league. Yes, replacing multiple teeth with individual implants can be quite expensive—but implant technology isn’t limited to one tooth at a time. A few well-placed implants can impart their proven durability and stability to other types of restorations.
For example, we can incorporate implants into a bridge for a series of missing teeth. Conventional bridges are normally fixed in place by altering and then crowning natural teeth on each side of the missing teeth gap with a fixed row of prosthetic (false) teeth in the middle to fill it. Instead, two implants placed at the ends of the gap can support the bridge rather than natural teeth. This not only provides greater stability for the bridge, it also avoids permanent altering the natural teeth that would have been used.
Implants can also support a fixed bridge to restore complete tooth loss on a jaw. The new bridge is attached to a few strategically placed implants along the jaw line to equally distribute biting forces. This can result in a strong hold with excellent durability.
We can also use implants to improve traditional dentures. Dentures normally rest directly on the gums’ bony ridges, depending on a snug fit for stability. But bone loss, a natural consequence of missing teeth, can still occur while wearing dentures, which may in fact accelerate the rate of loss due to the appliance’s constant pressure and friction against the gums.
Instead, just a few implants placed along the jaw can, with attachments built into the denture, hold it securely in place. This not only decreases the pressure on the gums, but the natural bone growth that occurs around the implant may even deter bone loss.
Depending on your situation, there could be a viable restoration solution involving implants. Visit our office for a complete examination and evaluation to see if implants could help change your smile forever.

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.
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.
