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.

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.
Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.
But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.
As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.
Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.
Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.
This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.
If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

In one respect, celebrities are no different from the rest of us—quite a few famous people love to collect things. Marie Osmond collects dolls (as well as Johnny Depp, reportedly); Leonardo DiCaprio, vintage toys. And, of course, Jay Leno has his famous fleet of cars. But Victoria Beckham's collection is unusually "familial"—she's kept all of her four children's "baby" teeth after they've fallen out.
Best known as Posh Spice of the 1990s group Spice Girls and now a fashion designer and TV personality, Beckham told People Magazine that she has an "entire bucket" of her kids' primary teeth. And, she recently added to it when her nine-year old daughter lost another tooth earlier this year.
You may or may not want to keep your child's baby teeth, but you'll certainly have the opportunity. Children start losing their first set of teeth around age 6 or 7 through early puberty. During the process, each tooth's roots and gum attachment weakens to the point that the tooth becomes noticeably loose. Not long after, it gives way and falls out.
Although a baby tooth doesn't normally need any help with this, children (and sometimes parents) are often eager to accelerate the process. A loose tooth can be annoying—plus there's often a financial incentive via the "Tooth Fairy!"
First off, there's not much harm in a child wiggling a loose tooth—it may even help it come out. It's also possible to help the tooth safely detach sooner by taking a small piece of tissue, folding it over the tooth and giving it a gentle downward squeeze. If it's loose enough, it should pop out.
If it doesn't, don't resort to more forcible measures like the proverbial string and a door—just wait a day or two before trying the gentle squeeze method again. Once the tooth comes out, the empty socket may bleed a bit or not at all. If heavy bleeding does occur, have the child bite down on a piece of clean gauze or a wet tea bag until it stops. You may also have them eat softer foods for a few days to avoid a resumption of bleeding.
Beyond that, there's little else to do but place it under your child's pillow for the Tooth Fairy. And if after their "exchange" with that famous member of the Fae Folk you find yourself in possession of the erstwhile tooth, consider taking a cue from Victoria Beckham and add it to your own collection of family memories.
Besides straight and translucent teeth, an attractive smile has another important component: balance. In a great smile, the visible areas of the teeth and gums are in balanced proportion to one another.
But what is the ideal proportion between teeth and gums? Although aesthetic appeal is largely “in the eye of the beholder,” dental professionals typically consider a properly sized tooth to be around 10 mm in visible length. As for the upper gums, no more than 4 mm of tissue should show when smiling. Teeth appearing shorter than 10 mm or the gums displaying more than 4 mm can create an effect called a “gummy smile.”
Fortunately, there are different approaches for correcting a gummy smile, depending on what's causing the appearance of gumminess. Not only are there different causes, but they can be diverse in nature.
Obviously, an actual excess of gum tissue can cause a smile to look gummy—but so can shortened teeth. One possible solution called crown lengthening could help correct either possibility. During the procedure, we remove any excess gum tissue or reposition the gums after reshaping the underlying bone to reveal more of the tooth crown. Worn or shortened teeth can also be made to look longer with porcelain veneers.
A gummy smile could also be caused by a hypermobile lip, in which the lip rises higher than normal while smiling. We may be able to prevent this temporarily by injecting Botox into the lip muscles, which paralyzes them and inhibits their ability to move upward. A more permanent approach is to surgically restrict the upward movement of the lip muscles.
The gums may also seem too prominent if the upper jaw is longer in proportion to the face. One way to correct this is orthognathic surgery, a procedure that moves the upper jaw to a higher position on the skull. This can reduce the jaw profile with the face and subsequently affect how much of the gums show while smiling.
These solutions range from relatively minor to significantly invasive. The first step, though, is to find out what's really behind your gummy smile before taking the next step to make it more attractive.

If you do the right things—keep your teeth clean, see the dentist regularly, and eat a "tooth-friendly" diet—you stand a good chance of having healthy teeth and gums later in life. Even so, after eating well over 75,000 meals by age 70, you can expect some wear from all that biting and chewing.
But there's normal wear—and then there's excessive wear, which can be caused by a variety of factors. When it occurs, accelerated wear can increase your risk of dental disease—and your shorter-toothed smile can make you look older than your actual age.
Here are 3 dental problems that can lead to accelerated tooth wear, and what you can do about them.
Tooth decay. This dental disease can severely weaken a tooth's protective enamel surface, which can in turn increase wear. You can minimize your chances of developing tooth decay by brushing and flossing your teeth daily and undergoing regular dental cleanings. And the sooner you receive treatment for any diagnosed decay, the less likely your enamel will suffer significant damage.
Poor bite. Properly aligned teeth mesh well together while biting and chewing, which minimizes wearing. But misalignments put undue stress on teeth that can lead to accelerated wear. By correcting a bite problem through orthodontics, we can properly align teeth so that they interact with each other normally for less wear.
Teeth grinding. This unconscious habit of gnashing or grinding teeth (often during sleep) can produce abnormally high biting forces. Among other adverse outcomes, this can also increase teeth wearing. If you grind your teeth, there are therapeutic methods that could reduce the habit. You can also obtain a custom night guard to reduce biting forces while you sleep.
If you've already experienced excessive dental wear, there are cosmetic options like porcelain veneers or dental bonding that can restore your smile to a more youthful appearance and help protect your teeth. But if you haven't reached that point, you can make sure you don't by taking care of your teeth and gums and seeking prompt dental treatment for problems leading to accelerated wear.
