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.

Inauguration night is usually a lavish, Washington, D.C., affair with hundreds attending inaugural balls throughout the city. And when you're an A-List celebrity whose husband is a headliner at one of the events, it's sure to be a memorable night. As it was for super model Chrissy Teigen—but for a slightly different reason. During the festivities in January, Teigen lost a tooth.
Actually, it was a crown, but once she told a Twitter follower that she loved it “like he was a real tooth.” The incident happened while she was snacking on a Fruit Roll-Up (those sticky devils!), and for a while there, husband and performer John Legend had to yield center stage to the forlorn cap.
But here's something to consider: If not for the roll-up (and Teigen's tweets on the accident) all of us except Teigen, her dentist and her inner circle, would never have known she had a capped tooth. That's because today's porcelain crowns are altogether life-like. You don't have to sacrifice appearance to protect a tooth, especially one that's visible when you smile (in the “Smile Zone”).
It wasn't always like that. Although there have been tooth-colored materials for decades, they weren't as durable as the crown of choice for most of the 20th Century, one made of metal. But while gold or silver crowns held up well against the daily grind of biting forces, their metallic appearance was anything but tooth-like.
Later, dentists developed a hybrid of sorts—a metal crown fused within a tooth-colored porcelain shell. These PFM (porcelain-fused-to-metal) crowns offered both strength and a life-like appearance. They were so effective on both counts that PFMs were the most widely used crowns by dentists until the early 2000s.
But PFMs today make up only 40% of currently placed crowns, down from a high of 83% in 2005. What dethroned them? The all-ceramic porcelain crown—but composed of different materials from years past. Today's all-ceramic crowns are made of more durable materials like lithium disilicate or zirconium oxide (the strongest known porcelain) that make them nearly as strong as metal or PFM crowns.
What's more, coupled with advanced techniques to produce them, all-ceramic crowns are incredibly life-like. You may still need a traditional crown on a back tooth where biting forces are much higher and visibility isn't an issue. But for a tooth in the “Smile Zone”, an all-ceramic crown is more than suitable.
If you need a new crown (hopefully not by way of a sticky snack) or you want to upgrade your existing dental work, see us for a complete exam. A modern all-ceramic crown can protect your tooth and enhance your smile.

Your child's dental development is in overdrive between birth and early adulthood. The rapid growth of the teeth, gums and jaws occurs mostly on its own—but tooth decay could significantly derail it.
Although most cases of dental disease occur in adults, tooth decay is a major problem for children, particularly involving primary teeth. These teeth are much more important than they seem given their short lifespans: Because they help incoming permanent teeth to align properly, their premature loss due to decay can create future bite problems.
To prevent this from happening, taking steps to prevent tooth decay in young children is well worth the effort. The best strategy is a double-pronged approach. You'll first want to address certain areas that directly contribute to tooth decay. You'll then want to add measures that strengthen the teeth themselves against the disease.
In regard to the former, reducing the levels of harmful bacteria in the mouth tops the list. These bacteria produce acid as a byproduct that in turn softens and erodes enamel, the teeth's natural barrier against decay. We reduce bacteria by eliminating dental plaque, a film of built-up food particles that feeds and shelters bacteria, through daily brushing and flossing.
Certain dietary choices may also contribute to bacterial growth. Refined sugar is a prime food source for bacteria, so limiting it in the diet will help reduce tooth decay. Furthermore, a diet rich in whole, unprocessed foods and dairy provide nutrients strengthen teeth against decay.
The other prong in defeating tooth decay mainly involves protective measures provided by your dentist. Sealants applied to the chewing surfaces of a child's teeth help protect the enamel from the buildup of bacteria in these highly susceptible areas. An occasional direct application of fluoride to teeth further strengthens their enamel, and makes them less susceptible to decay.
This approach can minimize the chances of tooth decay, but it won't eliminate the risk altogether. If it does occur despite your best efforts, prompt treatment can limit the damage and preserve the teeth. Working with your dentist, you can help ensure your child's teeth are protected from this damaging disease.

It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

Here's some good news: Teenagers are less likely than adults to lose teeth to dental disease. But there's also a flip side. Teens can still lose teeth, more likely from traumatic injury.
Fortunately, there are several options for replacing lost teeth like dentures or bridges. But the choice considered best by most dentists and patients is a dental implant. An implant tooth looks and functions like the real thing—and it's durable, capable of lasting for years, if not decades.
But there's a hitch with teens getting an implant: Even though they may have all their permanent teeth by adolescence, their jaws are still growing and developing. Natural teeth, with their attachment to the jaws by way of a periodontal ligament, can keep pace with this growth—but implants can't.
That's because an implant doesn't have this attachment to gum tissue like natural teeth, but to the jawbone alone. Hence, an implant tooth can't keep up with jaw development, and may eventually look like it's "sunk" into the gums in relation to the teeth around it.
It's best, then, to wait until a teen's jaws have fully developed before attempting an implant. In the meantime, though, they don't have to endure a smile marred by missing teeth, but can replace them with a temporary restoration. The two most common options are a partial denture or a modified bridge.
The partial denture is a lightweight version that's quite affordable. Although not as durable as other types of dentures, the appliance is only intended to last until the patient is old enough for a permanent implant.
The modified bridge is a prosthetic tooth with strips of dental material extending behind it that are bonded to the backs of the teeth on either side to hold it in place. It's likewise not as durable as a traditional bridge, but it can fill the bill until time to place an implant.
Although this adds an additional step in a teen's restorative journey after losing a tooth, it's necessary—waiting to place an implant after jaw maturity will help ensure a long-lasting result. In the meantime, a temporary tooth replacement will help them to enjoy a normal smile.
