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.

Dorit Kemsley isn't shy. Best known to fans as an outspoken and sometimes outrageous cast member of the reality show Real Housewives of Beverly Hills, Kemsley is never reticent about “mixing it up” with fellow castmates or their significant others. Recently, though, she confessed to something that left her less than confident: her smile.
Kemsley has been self-conscious about her smile because her teeth looked noticeably short, worn down from an unconscious habit of grinding her teeth. Although teeth grinding is more common among children (who normally grow out of it by adolescence), it can persist into adulthood, usually from difficulties managing high stress (a likely component in the fashion designer/reality show star's busy life).
Stress-induced teeth grinding can occur during waking hours or, more likely, during deep sleep. The accumulating, long-term effects from the habit can lead not only to worn teeth but to weakened gum support, a high risk of tooth fracture or jaw pain and dysfunction.
So, how do you know if you grind your teeth, especially if it's only happening at night? Typical signs include sore jaws after awaking from sleep, increased tooth pain or sensitivity or, like Kemsley, a noticeable difference in your tooth length. Your family or sleeping partner may also complain about the “skin-crawling” noise you make during the night.
There are ways to lessen the effects of teeth grinding. The first step is to have us verify the underlying cause for the habit. If it's tension from stress, then you might reduce the habit's occurrences by learning better stress management or relaxation techniques through individual counseling, group support or biofeedback therapy. We can also fit you with a mouth guard to wear at night or through the day that reduces the force generated during teeth grinding.
And if you've already experienced accelerated tooth wear like Kemsley with a resultant “small teeth” smile, you might pursue the same solution as the RHOBH star: dental veneers. These thin, life-like wafers of porcelain are custom-made to mask imperfections like chips, staining, slight tooth gaps and, yes, worn teeth.
Veneers are often less expensive and invasive than other cosmetic techniques, yet they can have a transformative effect, as Kemsley's Instagram followers have seen. In conjunction with other dental treatments needed to repair any underlying damage caused by a grinding habit, veneers are an effective fix for the smile you present to the world.
If you suspect you may have a grinding habit, see us for a complete examination. From there, we'll help you protect your teeth and your smile.
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.
