Semi-annual office cleanings are important for keeping teeth healthy and disease-free. If you’ve replaced some of your teeth with dental implants, though, you may be thinking they don’t need as much attention from your hygienist.
It’s quite the opposite — cleaning around implants is important, and actually requires additional attention. The reason for this relates to both how dental implants attach to the jaw and their constructive materials.
Natural teeth are held in place by the periodontal ligament with tiny fibers that attach to the teeth on one side of it and to the jawbone on the other. The ligaments and the gingival (gum) fibers (which are also attached to the tooth) provide some disease resistance to the teeth through its rich blood vessel and collagen network. Dental implants, on the other hand, anchor directly into the jawbone. The titanium integrates with the bone, which naturally attracts to the metal and grows around it, which provides the implant’s eventual attachment strength. The implant doesn’t attach to the gum tissue and won’t develop the same relationship with the periodontal ligament as natural teeth.
Bacterial plaque, the primary cause for tooth decay and periodontal (gum) disease, can collect on an implant crown just as readily as on a natural tooth. Although the materials that make up an implant can’t be affected by a plaque-induced infection, the gum tissues and supporting bone around it can. In fact, because implants lack the disease resistance of the gingival fibers and the ligament attachment, an infection can turn rapidly into a condition known as peri-implantitis that could cause bone and tissue loss and lead to the loss of the implant.
Your hygienist understands the importance of removing plaque and calculus (hardened plaque deposits) from around your dental implant. This often calls for different instruments made of plastics or resins that won’t scratch the implant’s highly polished surface. Scratches provide a haven for bacteria to collect and make it more difficult to dislodge them. Likewise, if the hygienist uses ultrasonic equipment that loosens plaque through vibration, the hygienist will often use nylon or plastic tips to minimize damage to the implant.
And don’t forget your own personal hygiene habits — they’re just as important with dental implants as with natural teeth. Keeping plaque under control, both at home and with your dentist, is crucial to longevity for your dental implants.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.
