Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.
Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.
Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.
Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.
However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.
Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. After several months, we may have enough regenerated bone to support an implant.
If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.
Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.
In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.
Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.
Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.
If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.
The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.
Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.
Even after losing a tooth in an on-court collision with an opposing player, Isaiah Thomas didn’t slow down. The Boston Celtics point guard completed the play…and the rest of the game. Unfortunately, that wasn’t the end of his dental problems — it was just the beginning.
Over the next few days, Thomas had a total of ten hours of oral surgery to treat problems with multiple teeth. He got a temporary bridge, and will receive a permanent one at a later date. He also got fitted for a custom-made mouthguard to prevent re-injury.
We’re pleased to see that Thomas is getting appropriate dental treatment. But it’s unfortunate that he didn’t get the mouthguard sooner; this one piece of inexpensive safety gear could have saved him a lot of pain and trouble. If you think mouthguards are strictly for full-contact sports, Thomas’ troubles should make you think again. In fact, according to a 2015 study in the journal Sports Health, the five sports with the highest overall risk of tooth loss are basketball, football, hockey, martial arts, and boxing. Plenty of other also involve the risk of dental injury.
The study also notes that some 5 million teeth are avulsed (knocked out) each year in the U.S. alone. Countless others are loosened, fractured or chipped. What’s more, it is estimated that the lifetime cost of treating an avulsed tooth is between $5,000 and $20,000. The cost of a custom-made mouthguard is just a small fraction of that.
Where can you or your child get a custom-made mouthguard? Right here at the dental office! These high-quality items are professionally fabricated from a model of your actual teeth, so they fit much better than an off-the-shelf one ever could. They offer superior protection, durability and comfort — because, after all, no mouthguard can protect you if it’s too uncomfortable to wear.
Thomas’ season is now over due to a hip injury, but at least he will now have time to rest and get his dental problems taken care of. Let’s hope his story will inspire more athletes — both professional and amateur — to prevent similar problems by wearing custom-made mouthguards. Whether you compete on a school team, enjoy a pick-up game after work, or play in the big leagues, a dental injury is one problem that you don’t need.
We always look forward to seeing our patients, but not all of you look forward to seeing us! If you’re one of them, don’t worry — we don’t take it personally. Dental anxiety prevents many people from seeking the care they require to restore or maintain a healthy smile.
But if dental problems are allowed to progress, they can affect not only the beauty of your smile and health of your mouth, but your overall wellness, too. Infection can travel from the mouth to other areas of the body, and dental disease exacerbates chronic health conditions like heart disease or diabetes.
Fear should never be an obstacle (in the immortal words of President Franklin Roosevelt, “…the only thing we have to fear is fear itself…”). And fortunately there are some safe options for those of us who can’t get past our anxiety when it comes to dental care:
Oral Sedation. A sedative medication can be prescribed that you take by mouth approximately an hour before your dental visit to minimize anxiety and promote relaxation.
Intravenous (IV; “intra” – inside, “venous” – vein) Sedation. If oral sedation isn’t entirely effective in facilitating treatment, then a medication combining a sedative for relaxation and a pain-blocking anesthetic can be delivered through or small needle or catheter that is gently inserted into a vein. This is referred to as “conscious sedation” because you are in a semi-awake state during which you are able to respond to verbal direction. It takes effect quickly, and you can come out of it quickly. However, you may not remember much about your procedure. It is very different from general anesthesia during which you are completely unconscious.
Dentists who offer IV sedation receive extensive training after which we must pass an exam and apply for a special permit that we maintain through continuing education. We carefully screen patients for eligibility and monitor you throughout so you can rest easy before, during, and after your procedure.

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.
