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.

It gradually dawned on our ancient ancestors that a healthy mouth was usually a clean one. To achieve that blessed oral state, they chewed on tree bark or employed primitive toothbrushes like bamboo sticks with hog hair bristles attached to their ends.
Today, we have better tools and methods for achieving a cleaner and healthier mouth. But these advancements do little good if a) we don't use them on a daily basis, and b) we're not proficient with them.
October is National Dental Hygiene Month, highlighting once again the importance of these two points for keeping teeth and gums as clean as possible. First and foremost, oral hygiene should never take a holiday—even a day or two of accumulated plaque, the bacterial biofilm that builds up on teeth surfaces, can trigger the occurrence of gum disease or tooth decay.
But while "showing up" every day to brush and floss goes a long way toward a healthy mouth, you also need to perform these tasks well. An inadequate job can leave residual plaque that could still cause disease.
Here are a few handy tips to improve your oral hygiene routine.
Do a thorough job. Plaque can be stubborn, clinging to the nooks and crannies of teeth and around the gum lines—and it can easily be missed while brushing. Be sure, then, to thoroughly work your toothbrush's bristles into all dental surfaces. Your efforts should take about 2 minutes to complete.
Don't be too aggressive. You may need "elbow grease" to clean your floors, but not your teeth. Too much pressure applied while brushing can damage enamel and gums. Instead, go easy when you brush and let the toothpaste's mild abrasives do the heavy lifting.
Use flossing tools. Many people avoid flossing because they find it too hard or cumbersome with traditional flossing thread. If this is a problem for you, consider using a flossing tool—a floss threader or pick, or even a water flosser appliance that uses pressurized water to break up and remove plaque.
Take the "tongue test." Wondering how well you're doing with your hygiene efforts? One quick way to find out is the "tongue test": Simply swipe your tongue across your teeth just after brushing and flossing. If they feel gritty rather than smooth, you may have left some plaque behind.
Besides your personal hygiene efforts, be sure you also have your teeth cleaned regularly by a dental hygienist to rid your mouth of any residual plaque and tartar (hardened plaque)—these can also cause dental disease. Professional care coupled with proficient daily hygiene will help ensure you have cleaner mouth and better dental health.

Are your stained teeth bumming you out? There's good news—you can transform that dull and dingy smile yourself with a tooth whitening product.
There are dozens of over-the-counter whitening kits that allow you to brighten your own smile. Although not as controlled and long-lasting as a dentist's professional whitening, these DIY kits can still give you effective results.
But since these products involve chemical solutions that bleach tooth enamel, there's a common concern about their safety. Could you be harming your teeth by using a home whitening kit?
The answer is no—as long as you follow the manufacturer's directions for using the product. These kits have been formulated with a lower percentage of bleaching agent (usually 10% carbamide peroxide) than whitening solutions used by dentists. They've also been subjected to several clinical studies gauging both their effectiveness and safety.
That said, though, exceeding a product's recommended directions and frequency of use could cause you problems. If not used properly, a bleaching solution can erode tooth enamel—and this protective tooth layer doesn't grow back! As long as you whiten "within the lines," so to speak, you shouldn't encounter this kind of situation.
With that said, though, there are good reasons to consult your dentist before using a whitening product, or have them perform the whitening for you.
For one thing, an over-the-counter whitening product won't work if the staining originates from inside a tooth. It's wise, then, to have a dental examination first before using a whitening product to uncover this or any other underlying dental problems that should be addressed first.
You may also find a professional whitening will give you a more desirable result. A stronger professional bleaching solution under a dentist's expert control can produce a brighter, longer lasting smile than a home use product. A dentist may also be able to control the level of brightness better to help you achieve the smile effect you desire, from subtle white to ultra-bright.
Whichever way you go, your dentist can advise you on your options and make sure your teeth are in good shape for whitening. The end result can be a brighter smile—and a brighter mood.

Hannah Bronfman, well-known DJ and founder of the health and beauty website HBFIT.com, took a tumble while biking a few years ago. After the initial pain and bruising subsided, all seemed well—until she started experiencing headaches, fatigue and unexplained weight gain. Her doctors finally located the source—a serious infection emanating from a tooth injured during the accident.
It's easy to think of the human body as a loose confederation of organs and tissues that by and large keep their problems to themselves. But we'd do better to consider the body as an organic whole—and that a seemingly isolated condition may actually disrupt other aspects of our health.
That can be the case with oral infections triggered by tooth decay or gum disease, or from trauma as in Bronfman's case. These infections, which can inflict severe damage on teeth and gums, may also contribute to health issues beyond the mouth. They can even worsen serious, life-threatening conditions like heart disease.
The bacteria that cause both tooth decay and gum disease could be the mechanism for these extended problems. It's possible for bacteria active during an oral infection to migrate to other parts of the body through the bloodstream. If that happens, they can spread infection elsewhere, as it appears happened with Bronfman.
But perhaps the more common way for a dental disease to impact general health is through chronic inflammation. Initially, this defensive response by the body is a good thing—it serves to isolate diseased or injured tissues from healthier tissues. But if it becomes chronic, inflammation can cause its own share of damage.
The inflammation associated with gum disease can lead to weakened gum tissues that lose their attachment to teeth. But clinical research over the last few years also points to another possibility—that periodontal inflammation could worsen the inflammation associated with diseases like heart disease, diabetes or arthritis.
Because of this potential harm not only to your teeth and gums but also to the rest of your body, you shouldn't take an oral injury or infection lightly. If you've had an accident involving your mouth, see your dentist as soon as possible for a complete examination. You should also make an appointment if you notice signs of infection like swollen or bleeding gums.
Prompt dental treatment can help you minimize potential damage to your teeth and gums. It could also protect the rest of your health.

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.
