If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

Root canals often get a bum rap. Although the procedure saves millions of teeth every year, it's often erroneously portrayed as an unpleasant experience. And if that wasn't enough, a long-discredited medical theory has found new life on the internet asserting root canals are a health danger.
First off, root canals play an immensely important role in treating teeth with advanced decay. If not promptly treated, a cavity can turn into a major infection of the interior tooth pulp and root canals, and ultimately the supporting bone. Teeth with this level of decay are not long for this world.
A root canal treatment stops this disease process in its tracks. After numbing the tooth and surrounding gums, we drill a small hole into the tooth's interior and then remove all of the infected tissue within the pulp and root canals. After disinfecting these areas, we fill them with a rubber-like substance called gutta percha.
After sealing off the access hole—and later capping the tooth with a life-like crown—the tooth is secure from further decay. And, by the way, the procedure doesn't hurt, thanks to local anesthesia. If anything, any pain caused by the decay attacking the tooth's nerves has now been alleviated.
So, what about the idea floating on the Web that root canals are dangerous? The "root" for this conjecture is a theory by Weston Price, an early 20th Century dentist, that leaving a "dead" body part in the body leads to various health problems (including cancer). That would include a root-canaled tooth, which has had the living tissue in the pulp removed.
There's just one problem—Weston's theory was fully investigated in the 1950s and overwhelmingly discredited. The supposed cancer threat was also reviewed in a 2013 study, which found no link between root canals and increased cancer risk. In fact, dental patients who had undergone several root canals had a diminished risk.
Like all other health procedures, root canals have some risks of complication. But those complications are far from life-threatening—it's tooth-saving benefits are often worth the risk. So, fear not if your dentist says you need a root canal. It won't hurt and it won't endanger your health—and it could save your tooth.

There are plenty of hilarious videos of groggy patients coming out of wisdom teeth surgery to keep you occupied for hours. While many of these have turned everyday people into viral video stars, every now and then it really is someone famous. Recently, that someone was Seattle Seahawks quarterback Russell Wilson.
The NFL star underwent oral surgery to remove all four of his third molars (aka wisdom teeth). His wife, performer and supermodel, Ciara, caught him on video as he was wheeled to recovery and later uploaded the clip to Instagram. As post-wisdom teeth videos go, Wilson didn't say anything too embarrassing other than, "My lips hurt."
Funny videos aside, though, removing wisdom teeth is a serious matter. Typically, the third molars are the last permanent teeth to erupt, and commonly arrive late onto a jaw already crowded with other teeth. This increases their chances of erupting out of alignment or not erupting at all, remaining completely or partially submerged within the gums.
This latter condition, impaction, can put pressure on the roots of adjacent teeth, can cause abnormal tooth movement resulting in a poor bite, or can increase the risk of dental disease. For that reason, it has been a common practice to remove wisdom teeth preemptively, even if they aren't showing any obvious signs of disease.
In recent years, though, dentists have become increasingly nuanced in making that decision. Many will now leave wisdom teeth be if they have erupted fully and are in proper alignment, and they don't appear to be diseased or causing problems for other teeth.
The best way to make the right decision is to closely monitor the development of wisdom teeth throughout childhood and adolescence. If signs of any problems begin to emerge, it may become prudent to remove them, usually between the ages of 16 and 25. Because of their location and root system, wisdom teeth are usually removed by an oral surgeon through one of the most common surgeries performed each year.
This underscores the need for children to see a dentist regularly, beginning no later than their first birthday. It's also a good idea for a child to undergo an orthodontic evaluation around age 6. Both of these types of exams can prove helpful in deciding on what to do about the wisdom teeth, depending on the individual case.
After careful monitoring throughout childhood and adolescence, the best decision might be to remove them. If so, take it from Russell Wilson: It's worth becoming the star of a funny video to protect both current and future dental health.
A wise sage once said the largest room in the world is the "room for improvement." Indeed, many modern advances would never have happened if someone hadn't first asked, "How can I make this better?"
Dentures and bridges are a case in point. Both of these tooth replacement methods have a long, successful track record in restoring functional, life-like teeth. But a recent development has made them even better: the incorporation of dental implants.
Most people associate implants, metallic posts imbedded in the jawbone, with single tooth replacements. But a few strategically placed implants can connect to and support a full removable denture (or overdenture). We can also use them to permanently affix a full or partial bridge without altering any remaining teeth as with a regular bridge.
There are two great benefits to using implants in this way. The most obvious is that they provide greater support for restorations than the traditional means for securing them in place. But there's also a less obvious benefit: They help sustain and improve bone health.
When you lose teeth, there's a high probability of bone loss. The bone is constantly forming new cells to replace older cells that have dissolved. The forces generated during chewing travel up through the teeth and help stimulate new bone growth. When teeth go missing, though, that stimulus disappears.
As a result, new cell formation can't keep up with the loss of older cells, causing the volume and density of jawbone to diminish over time. And this gradual bone loss continues to occur even with dentures or bridges, which can't replicate the chewing stimulus. Even worse, dentures irritating the bony ridges of the jaw may actually accelerate bone loss.
But the titanium in dental implants attracts bone cells, which readily grow and adhere to the implant surface. They can stop the progression of bone loss, or even help stimulate more growth. That bone growth benefit is also applicable when incorporated with dentures or bridges.
If you're looking at a denture or bridge restoration, consider implant support. It may even be possible to retrofit your existing dentures for implants. It could give you a more secure restoration and healthier bone.

We instinctively know when a smile looks normal—and when it doesn't. It could be that something simply looks out of place like crooked teeth. But we might also notice when something is missing—as with one or both of the canine teeth.
The canine teeth align just under the eyes and are recognizable by their pointed ends. When they're missing, the smile looks “incomplete.” But “missing” in this case could mean “invisible”—the teeth are there, but hidden within the gums because they failed to come in properly and became impacted. This often happens on a smaller jaw where other teeth have crowded into the space intended for them.
Fortunately, we may have a remedy, and not just for appearance's sake—any impacted tooth can cause health problems, from gum abscesses to root damage of neighboring teeth. Although this might necessitate their surgical removal, we might also be able to coax them through the gums into better position in the jaw, if they're in a reasonably good position. This could result in both a boost to a patient's oral health and a more normal looking smile.
First, though, a patient will need to undergo a thorough bite evaluation by an orthodontist. Besides pinpointing the impacted teeth's precise location with x-rays or CT technology, an orthodontist will also want to assess the positions and condition of the rest of the teeth. If the conditions are right and there's enough room in the jaw, the orthodontist may recommend drawing the impacted canines into proper alignment in the jaw.
The process starts when an oral surgeon exposes the impacted teeth by surgically cutting through the gum tissue. They then attach a small bracket to the tooth with a tiny metal chain attached, the other end of which is looped over orthodontic hardware attached to other teeth. The tension on the chain by the hardware gradually nudges the teeth downward out of the gums. This is usually done in coordination with other measures to fully correct the bite.
If the procedure is successful, bringing the canines out of impaction reduces the problems those teeth could cause the person's oral health. But just as important, it can restore normality to their smile.
