Teeth-replacing dental implants not only look life-like, they’re made to last. For one thing, the metals and dental materials used in them are impervious to bacterial infection.
But that doesn’t mean implants are impervious to failure. Implants depend on the bone and other natural mouth structures for support. If the bone becomes weakened due to disease, the implant could become unstable and ultimately fail.
Peri-implantitis, the condition that can lead to this kind of failure, is a major concern for implant longevity. It’s a type of periodontal (gum) disease triggered by plaque, a thin film of food particles that can build up quickly in the absence of adequate brushing and flossing. The gum tissues around the implant become infected and inflamed.
If the infection isn’t properly treated with renewed oral hygiene and clinical plaque removal, it could spread below the gum line and begin to damage the underlying gum tissues and bone. This could destroy the all-important connection between the titanium implant post and the bone. The implant could eventually loosen and become completely detached from the bone.
The key is early intervention before the bone becomes damaged. Besides plaque removal we may also need to apply antibiotics in some form to control the growth of disease-causing bacteria. If the disease has fairly advanced we may also need to consider surgical repair to strengthen the attachment between implant and bone.
You can help to avoid peri-implantitis altogether by practicing consistent daily brushing and flossing around all your teeth including the implant, and seeing your dentist at least twice a year for cleanings and checkups. And by all means see your dentist if you notice any signs of gum swelling, redness or bleeding. Staying on top of your gum health will help not only the natural tissues and remaining teeth in your mouth, it will help preserve your implants for decades to come.
If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
In the winter months, when the daylight hours grow few, we celebrate the season with holiday lights and good cheer. This season of hope and renewal also gives us a chance to think about the future — to take stock of where we’ve been, and even plan for some changes in the new year.
Deciding to improve your overall health is one great way to start off the year. Of course, we know many resolutions that begin with crash diets and extreme fitness programs won’t be kept up for very long. But if there were one permanent change you could make, which would both enhance your appearance and improve your health… would you do it? If you are missing teeth — or if you’re wearing dentures that aren’t working the way you’d like — then perhaps we can offer a suggestion: Consider dental implants.
Besides being an obvious blemish on your appearance, missing teeth also create problems you can’t see. For one, it’s harder to eat a proper, balanced diet if you have trouble chewing certain foods, potentially leading to serious nutritional problems. For another, when teeth are lost, the bone in your jaw that used to surround them begins to deteriorate. This can cause you to have a prematurely aged look, and make you appear unhappy even when you’re not.
Unfortunately, dentures don’t solve these problems — in fact, they tend to compound them. Many denture wearers report they have problems eating; some even say they eat better without dentures. And dentures don’t stop bone loss; in many cases, especially when they don’t fit correctly, they actually accelerate it.
But there’s really no reason you have to get by with missing teeth. Since they were introduced some three decades ago, dental implants have offered people a better way to replace lost teeth. With implants, you can eat your favorite foods again, smile with complete assurance, and stop worrying about dentures that may fit poorly or slip out at the wrong times.
Fixed solidly in your jaw in a minor surgical procedure, dental implants function just like your natural teeth. Their natural look and “feel” makes it easy to forget they aren’t the teeth you were born with. Best of all, they can last the rest of your life… unlike bridges or dentures. Because they offer a permanent solution, implants can be quite cost-effective in the long run. But the way they can restore your confidence and make you feel good about yourself isn’t something you can put a price on.
So if you have ever thought about making a New Year’s resolution that will really improve your health and well-being — consider dental implants. Just call our office to schedule a consultation. You can learn more in Dear Doctor magazine’s in-depth guide, “Dental Implants.”
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.
