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.

The dental implant is the closest thing in modern dentistry to a natural tooth. This is because an implant replaces more than the visible crown — it also replaces the root, thanks to a metal post imbedded in the bone.
But what if you have a metal allergy — are you out of luck replacing a tooth with an implant? Before answering this question, let's take a closer look at metal allergies.
An allergy is an overreaction of the body's immune system to a particular foreign substance. This response can be as inconsequential as a minor rash or as life-threatening as a shutdown of the body's organ systems. You can be allergic to anything, including metals.
Usually, these allergies are to specific kinds of metals. For example, about 17% of women and 3% of men are allergic to nickel, while smaller percentages are allergic to cobalt or chromium. Most allergic reactions to metal occur from external contact with jewelry or similar metal items that create rashes or other anomalies on the skin. On a more serious note, an allergy to metal in a body replacement part could result in the body rejecting it.
Metals have also played an important role in dental care, particularly dental amalgam used for tooth fillings. Dental amalgam is a mixture of a precious metal like gold or silver with other metals like copper, tin and, in small amounts, mercury. While dental amalgam has been used safely for decades, there have been rare cases of inflammation or rashes.
This brings us to dental implants and the most common metal used in them, titanium. The commercial version of this metal is highly prized in medical and dental applications because it has a special affinity with bone. Bone cells readily grow and adhere to the metal, which strengthens the bond between the implant and the jawbone.
Even if you have a rare allergy to certain metals, it's even rarer that would include titanium. In one particular study of 1,500 implant patients less than 1% reported any reaction at all.
If you're concerned, you can undergo testing to see if you react to titanium. More than likely, though, you'll be able to join the millions of other patients who have successfully restored their smiles with dental implants.

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.

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.
