Placing a dental implant within the jawbone requires a surgical procedure. For most people it’s a relatively minor affair, but for some with certain health conditions it might be otherwise. Because of their condition they might have an increased risk for a bacterial infection afterward that could interfere with the implant’s integration with the bone and lead to possible failure.
To lower this risk, dentists for many years have routinely prescribed an antibiotic for patients considered at high-risk for infection to take before their implant surgery. But there’s been a lively debate among health practitioners about the true necessity for this practice and whether it’s worth the possible side effects that can accompany taking antibiotics.
While the practice still continues, current guidelines now recommend it for fewer health conditions. The American Dental Association (ADA) together with the American Heart Association (AHA) now recommend antibiotics only for surgical patients who have prosthetic heart valves, a history of infective endocarditis, a heart transplant or certain congenital heart conditions.
But patients with prosthetic joint replacements, who were once included in the recommendation for pre-surgical antibiotics, are no longer in that category. Even so, some orthopedic surgeons continue to recommend it for their joint replacement patients out of concern that a post-surgical infection could adversely affect their replaced joints.
But while these areas of disagreement about pre-surgical antibiotics still continue, a consensus may be emerging about a possible “sweet spot” in administering the therapy. Evidence from recent studies indicates just a small dose of antibiotics administered an hour before surgery may be sufficient to reduce the risk of infection-related implant failure with only minimal risk of side effects from the drug.
Because pre-surgical antibiotic therapy can be a complicated matter, it’s best that you discuss with both the physician caring for your health condition and your dentist about whether you should undergo this option to reduce the infection risk with your own implant surgery. Still, if all the factors surrounding your health indicate it, this antibiotic therapy might help you avoid losing an implant to infection.

You’ve invested quite a bit in your new dental implants. And it truly is an investment: because of implants’ potential longevity, their long-term costs could actually be lower than other restorations whose upfront costs might be less.
But to better ensure their longevity, you’ll need to keep your implants and the natural tissues supporting them clean of bacterial plaque, a sticky biofilm that can cause periodontal (gum) disease. Although the implant itself is unaffected by disease, the natural tissues around it can be. An infection could ultimately weaken the bone supporting the implant and lead to its failure.
Such an infection involving implants could advance rapidly because they don’t have the natural defenses of the original teeth. Our natural teeth are connected to the jaw through the periodontal ligament, a collagen network that attaches to both the teeth and the bone through tiny tissue fibers. This connection also provides access to antibodies produced by the body to fight infection.
By contrast, we place implants directly into the jawbone. While this creates a very secure attachment, the implant won’t have the same connection as teeth with the body’s immune system. That means any infection that develops in surrounding tissues can spread much more rapidly—and so must be dealt with promptly.
Treating this particular form of gum disease (known as peri-implantitis) is similar to infections with natural teeth and gums, with one important difference involving the tools we use to remove plaque from them. While natural teeth can handle metal scalers and curettes, these can create microscopic scratches in the porcelain and metal surfaces of an implant and create havens for further bacterial growth. Instead, we use instruments made of plastic or resin that won’t scratch, as well as ultrasonic equipment to vibrate plaque loose.
To avoid an infection, it’s important that you brush your implants and surrounding tissues just like you would your natural teeth (be sure you use a soft-bristled brush). And keep up regular dental visits for thorough cleanings and checkups to stay ahead of any developing gum infection. Maintaining your dentures will help ensure they continue to brighten your smile for a long time.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?
Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?
Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.
Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.
But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?
In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.
Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.
What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

You’ve decided to obtain dental implants for your missing teeth. It’s a good choice — they provide the closest restoration to the function and appearance of natural teeth. You will, however, need to undergo a surgical procedure to imbed the implants’ threaded titanium posts into supporting bone.
It’s understandable if you’re a little apprehensive about undergoing surgery. We’re here, though, to set your mind at ease: implantation is a relatively minor procedure carefully planned in advance. Most patients experience no discomfort during the procedure and very little afterward.
We begin by completely numbing the surgical site with a local anesthetic. If you have a high level of anxiety, we can also administer a sedative or similar medication to help you relax. We then access the underlying bone through a series of incisions that create a flap in the gum tissue that we’ll later suture closed.
It’s quite common to have prepared a surgical guide or template beforehand. The template placed in the mouth marks the exact site for a small channel (or hole) we create in the bone. We then incrementally increase the size of the hole by drilling until it matches precisely the implant’s size and shape. This takes time to avoid overheating and damaging the bone.
We then remove the implant from its sterile packaging and insert it into the opening. We’ll also take x-rays to ensure correct positioning, which is critical for achieving an attractive result. We then suture the gum flap in place using stitches that will eventually dissolve. The implant will then integrate with the bone for a few weeks to create a strong, durable hold before we continue with the restoration.
Most patients can manage any post-surgical discomfort with mild anti-inflammatory pain relievers like aspirin or ibuprofen, although we can prescribe something stronger if you need it. We may also prescribe a mouthrinse with an anti-bacterial agent like chlorhexidine for you to use while the gums are healing to reduce the risk of infection.
Implant surgery is part of a long process that will eventually result in regaining the function of your lost teeth. What’s more, undergoing this minor procedure will also help you regain something just as important — a beautiful smile.

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.
