After years battling disease, your troubled tooth reached its useful life's end. It's been extracted, and we've replaced it with a life-like dental implant. So now, as far as the implant goes, disease is no longer an issue…right?
Sorry, no—though not to the same degree as a natural tooth, an implant could be endangered by gum disease. Although the implant's materials can't be infected, the supporting gums and bone can.
In fact, there's a particular type of gum disease associated with implants known as peri-implantitis (“peri” around an implant; “itis” inflammation) that first affects the gums surrounding an implant. Although peri-implantitis can arise from an excess of dental cement used to affix the crown to the implant, it most commonly starts like other forms of gum disease with dental plaque.
Dental plaque, and its hardened form calculus (tartar), is a thin, bacterial biofilm that builds up on teeth surfaces. It can quickly accumulate if you don't remove it every day with proper brushing and flossing. The bacteria living in plaque can infect the outer gum tissues and trigger inflammation.
Gum disease around natural teeth can spread quickly, but even more so with implants. That's because the natural attachment of the gums helps supply antibodies that impede infection. Implants, relying solely on their connection with the bone, don't have those gum attachments. As a result, peri-implantitis can move rapidly into the supporting bone, weakening the implant to the point of failure.
The good news, though, is that peri-implantitis can be treated successfully through aggressive plaque removal and antibiotics. But the key to success is to catch it early before it progresses too far—which is why you should see your dentist at the first sign of gum swelling, redness or bleeding.
You can also prevent peri-implantitis by practicing daily brushing and flossing, including around your dental implant. You should also see your dentist twice a year (or more, if they advise) for cleanings and checkups.
Dental implants overall have a greater than 95% success rate, better than any other tooth restoration system. But they still need daily care and regular cleanings to ensure your implants are on the positive side of those statistics.
The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

If you've been dealing with a tooth that needs to be removed—or it's already missing—you may be looking to replace it with a dental implant. And it's a great choice: No other restoration can provide the appearance and function of a real tooth like an implant.
You and your smile are ready for it. The question is, though, are your gums and underlying bone ready? These dental structures play a critical role in an implant's stability and eventual appearance. A problem with them may make placing an implant difficult if not impossible.
An implant requires around 2.0 millimeters of bone thickness surrounding the implant surface for adequate support and to minimize the chances of gum recession. But tooth loss often leads to bone loss that can drop its thickness below this threshold. This can make placing an implant problematic.
Fortunately, though, we may be able to address the lack of sufficient bone through bone grafting. By placing grafting material within the empty socket, we create a scaffold for new bone cells to grow upon. Over time this subsequent growth may be enough to maintain an adequate thickness of bone for an implant to be placed.
The gums may also pose a problem if they've shrunk back or receded from their normal positions, as often happens because of gum disease (which may also have precipitated the tooth loss). Again, grafting procedures can help ensure there's adequate gum coverage for the implant. And healthier gums may also help protect the underlying bone from loss.
There are several techniques for placing gum tissue grafts, depending on how much recession has taken place. One procedure in particular is often used in conjunction with implant placement. A small layer of synthetic collagen material or gum tissue referred to as pa dermal apron is included with the implant when its placed. Settling into the bone socket, this apron helps thicken the gum tissues, as well as preserve the underlying bone.
During your preliminary exams, we'll assess your bone and gum health to determine if we should take any steps like these to improve them. It may add some time to the implant process, but the end result will be well worth it.

If you've thought the ads for a “new tooth in one day” seemed too good to be true, we have…sort of good news. You can get a new “tooth” in one visit, but only if your dental situation allows it.
The restoration in question is a dental implant, a metal post (usually titanium) surgically imbedded into the jawbone. They're especially durable because bone cells naturally grow and adhere to an implant's titanium surface, a process called osseointegration. Over time this process creates a strong bond between implant and bone.
Usually, we allow a few weeks for the implant to fully integrate with the bone before attaching the visible crown. With “tooth in one day,” though, we attach a crown at the same time as we install the implant, albeit a temporary crown. It's more aesthetic than functional, designed to avoid biting forces that could damage the implant while it integrates with the bone. When that process finishes, we'll install a permanent porcelain crown.
The health of your supporting bone and other structures will largely determine whether or not you're a candidate for this “tooth in one day” procedure. Your bone must be sufficiently healthy, as well as the gums surrounding the implant and the tooth's bony socket.
If, on the other hand, you have significant bone loss, gum recession or socket damage, we may first need to deal with these, usually by grafting tissue to the affected areas to stimulate new growth. Your implant, much less a temporary crown, will likely have to wait until the affected tissues have healed.
The bone can also be healthy enough for implant placement, but might still need time to integrate with the implant before attaching any crown. Instead, we would suture the gums over the implant to protect it, then expose and attach a permanent crown to the implant a few weeks later.
Obtaining even a temporary crown the same day as your implant can do wonders for your appearance. A more important goal, though, is a new tooth that you can enjoy for many, many years. To achieve that may mean waiting a little longer for your new beautiful smile.

You feel great about your new smile, thanks to dental implants! And you may also be feeling relief as the problems with your former teeth fade into the past.
But that doesn’t mean you can drop your guard on periodontal (gum) disease. Even though implants are impervious to decay, the natural tissues supporting them are vulnerable to periodontal (gum) disease. If they become diseased, your implants could lose their bone support and eventually fail.
And that failure could happen quickly. That’s because, as life-like as they are, implants don’t have one important advantage of real teeth: an attachment to a connective tissue called the periodontal ligament. This tough but elastic ligament lies between the teeth and the bone, attaching to both with tiny extending fibers and holding the teeth in place.
And that’s not all: Because the periodontal ligament contains an abundance of blood vessels, it can supply antibodies to help fight infection. The body’s defenses may not be able to stop disease, but they can certainly inhibit its progress.
Implants can’t benefit from this infection-fighting mechanism. So, when an infection arises in the gums surrounding an implant, it can spread rapidly through a form of gum disease known as peri-implantitis (literally “inflammation around an implant”). If we don’t stop it with prompt treatment, you could lose bone support from your implant and eventually lose it, sometimes in quick fashion.
That’s why you should clean your implants everyday like you do the rest of your teeth with brushing and flossing. You should also visit us regularly for dental cleanings. A dental cleaning involving implants is similar to one with natural teeth, except the hygienist won’t use metal instruments on the implants—this could create tiny scratches on their surface. Instead, they’ll use nylon or plastic instruments or ultrasonic equipment to clean them.
You should also make a dental appointment as soon as you notice swollen, reddened or bleeding gums. If you have gum disease, we can stop the infection through treatment and restore your gums to health. This can be a long and involved process, but it’s necessary to preserve your implants.
It’s true that implants can change your life. If you want to enjoy that change for a long time, take care of your implants and the natural tissues that support them.
