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.

What's so special about dental implants — and why should you consider one to replace a missing tooth?
Although they've only been widely available for thirty years, dental implants have climbed to the top of tooth replacement choices as the premier restorative option. Since their debut in the 1980s, dentists have placed over 3 million implants.
There's one overriding reason for this popularity: in structure and form, dental implants are the closest replacement we have to a natural tooth. In fact, more than anything else an implant is a root replacement, the part of the tooth you don't see.
The artificial root is a titanium post surgically imbedded into the jaw bone. Later we can attach a porcelain crown to it that looks just like a visible tooth. This breakthrough design enables implants to handle the normal biting forces generated in the mouth for many years.
There's also an advantage in using titanium dental implants. Because bone cells have a special affinity to the metal, they will grow and attach to the implant over time. Not only does this strengthen the implant's hold within the jaw, the added growth also helps deter bone loss, a common problem with missing teeth.
It's this blend of strength and durability that gives implants the highest success rate for any tooth replacement option. Over 95% of implants placed attain the 10-year mark, and most will last for decades.
Dental implant treatment, however, may not be possible in every situation, particularly where significant bone loss has occurred. They're also relatively expensive, although more cost-effective than other options over the long term.
Even so, implants can play an effective and varied role in a dental restoration. While single implants with attached crowns are the most common type of replacement, they can also play a supporting role with other restorative options. As few as two strategically placed implants can provide a more secure connection for removable dentures or fixed bridges.
You'll need to first undergo a thorough dental examination to see if implants could work for you. From there, we'll be happy to discuss your options for using this "best of the best" restoration to achieve a new, beautiful smile.

Singer and actor Demi Lovato has a new claim to fame: formidable martial artist. When she is not in the recording studio, on stage or in front of the camera, Lovato can often be found keeping in shape at Jay Glazer's Hollywood (California) gym. Glazer, who is best known as a sports journalist, also runs conditioning programs for professional athletes and celebrities based on mixed martial arts. On March 6, Glazer got more than he bargained for when 5'3" Lovato stepped into the ring and knocked out his front tooth.
Glazer reportedly used super glue to put his tooth back together. Not a good idea! While it may not be convenient to drop everything and get to the dental office, it takes an expert to safely treat a damaged tooth. If you glue a broken tooth, you risk having to undergo major work to correct your temporary fix—it's no easy task to "unglue" a tooth, and the chemicals in the glue may damage living tooth tissue as well as the surrounding gum and bone.
Would you know what to do in a dental emergency? Here are some guidelines:
- If you chip a tooth, save the missing piece if possible. We may be able to reattach it.
- If your tooth is cracked, rinse your mouth with warm water, but don't wiggle the tooth around or bite down on it. If it's bleeding, hold clean gauze to the area and call our office.
- If your tooth is knocked loose or is pushed deeper into the socket, don't force the tooth back into position on your own. Immediate attention is very important.
- If your tooth is knocked out, there's a chance it can be reattached. Pick up the tooth while being careful not to touch the root. Then rinse it off and have either someone place into its socket, or place it against the inside of your cheek or in a glass of milk. Please call the office immediately or go to a hospital.
What's the best thing to do in an emergency? Call us right away, and DON'T super glue your tooth! You can prevent worse problems by letting a professional handle any dental issues. And if you've been living with a chipped, broken or missing tooth, call us to schedule an appointment for a consultation—there are several perfectly safe ways to restore your smile. Meanwhile, if you practice martial arts to keep in shape, think twice before getting into the ring with Demi Lovato!
Millions of microorganisms call your mouth home—and while most are friendly, some are not. An invasive procedure like implant surgery can disrupt the mouth's soft tissues and allow disease-causing bacteria to enter the bloodstream.
This isn't necessarily a major concern if your immune system is sound—your body will move quickly to quash any developing infection. But if your body's defense is weak or compromised by other health conditions, an ensuing infection could cause you problems. In the case of a dental implant, a localized infection around it could lead to its failure.
The bone normally grows and adheres to the surface of an implant soon after it's placed, giving it the added strength and durability for which implants are best known. A bacterial infection, though, could impede bone integration and weaken the implant's hold within the jaw.
One way to avoid this is by treating patients at high risk for infection with an antibiotic before the procedure. In one recent study, researchers concluded that patients receiving a 2-gram dose of amoxicillin an hour before implant surgery helped reduce the risk of future implant failure.
But before taking this route, the dentist must first decide whether antibiotic pre-treatment might be more detrimental than beneficial to an individual patient. Antibiotics can cause side effects in certain people ranging from diarrhea to allergic reactions. Healthcare providers must also be prudent with administering antibiotics for the good of society in general—overuse can potentially give rise to antibiotic-resistant bacteria.
A number of healthcare associations highly recommend antibiotic pre-treatment for any dental patient with prosthetic heart valves, a history of infective endocarditis, a heart transplant and similar heart conditions. They also recognize patients with conditions like prosthetic joints, weakened immune systems, diabetics or other serious health problems could also benefit from antibiotic pre-treatment, but leave it to the physician's discretion on whether or not it's appropriate for an individual patient.
If you're planning to undergo implant surgery or a similar procedure and are concerned about infection, speak with your dentist about whether you would qualify and benefit from antibiotic pre-treatment. If appropriate, taking an antibiotic beforehand could minimize your infection risk.

In the realm of restorative dentistry, dental implants are king. A dental implant can replace a tooth with a permanent, life-like restoration with a solid reputation for durability.
Implants are also known for one other quality — variety. Not all implants are alike, and they have varied applications for use. Available in various shapes and sizes, they can be used for a single tooth or as part of a multiple tooth bridge or overdenture. And while their basic architecture is the same, you also have two options for how the permanent crown (the visible tooth portion) attaches to the implant: screwed or cemented.
A screw attachment can securely fasten a crown to an implant without the need for cement; it also allows for easy removal for repair or replacement should the crown become damaged or worn. On the other hand, it could pose a cosmetic problem — even though the access hole for the screw may be covered with a tooth-colored filling, it could still be distinguishable from the rest of the crown. There’s also a slight risk of the crown chipping around the access hole.
A crown cemented to the implant won’t have this cosmetic issue with an access hole, and will look just like a natural tooth. But unlike a screwed crown, removing a cemented crown can be more difficult. The cement may also cause gum inflammation and potential bone loss in sensitive patients.
The condition of your mouth, the type of implant you’re receiving and other circumstances will all factor into determining which method is best for you. If we’re “immediately loading” the crown (meaning we’re affixing a temporary crown to the implant immediately after placement in the jaw), then the screw method may be more advantageous. Aesthetically speaking, though, a cemented crown may be a better option in terms of final smile appearance.
But whichever method is used, you’ll still benefit from what implants do best — help you regain the function lost from a missing tooth and change your smile for the better.
