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.

Love at first sight—it's an endearing notion found in movies and novels, but perhaps we're a little skeptical about it happening in real life. Then again, maybe it does once in a blue moon. According to supermodel Gisele Bündchen, something definitely happened the first time she met pro quarterback Tom Brady in 2006. And it all began when he smiled.
“The moment I saw him, he smiled and I was like, 'That is the most beautiful, charismatic smile I've ever seen!'” Bündchen said in an article for Vogue magazine. That was all it took. After a three-year romance, they married in 2009 and have been happily so ever since.
Both Brady and Bündchen have great smiles. But they also know even the most naturally attractive smile occasionally needs a little help. Here are three things our happy couple have done to keep their smiles beautiful—and you could do the same.
Teeth whitening. Bündchen is a big proponent of brightening your smile, even endorsing a line of whitening products at one point. And for good reason: This relatively inexpensive and non-invasive procedure can turn a dull, lackluster smile into a dazzling head-turner. A professional whitening can give you the safest, longest-lasting results. We can also fine-tune the whitening solution to give you just the level of brightness you want.
Teeth straightening. When Bündchen noticed one of her teeth out of normal alignment, she underwent orthodontic treatment to straighten her smile. Rather than traditional braces, she opted for clear aligners, removable trays made of translucent plastic. Effective on many types of orthodontic problems, clear aligners can straighten teeth while hardly being noticed by anyone else.
Smile repair. Brady is a frequent client of cosmetic dentistry, sometimes due to his day job. During 2015's Super Bowl XLIX against the Seattle Seahawks, Brady chipped a tooth, ironically from “head-butting” his Patriots teammate Brandon LaFell after the latter caught a touchdown pass. Fortunately, he's had this and other defects repaired—and so can you. We can restore teeth as good as new with composite resin bonding, veneers or crowns.
This superstar couple, known for their advocacy of all things healthy, would also tell you a beautiful smile is a healthy one. You can help maintain your smile's attractiveness with daily brushing and flossing to lower the risk of staining and dental disease, regular dental visits, and “tooth-friendly” eating habits.
And when your teeth need a little extra TLC, see us for a full evaluation. You may not be in the spotlight like this celebrity couple, but you can still have a beautiful smile just like theirs.

You've just finished your daily brushing and flossing. How did you do? Swiping your tongue across your teeth can generally tell you: It's a good sign if it glides smoothly; but if it feels rough and gritty, you better take another run at it.
This "tongue test," however, only gives you a rough idea of how well you're removing plaque, that thin bacterial film on teeth most responsible for dental disease. Plaque, though, can be sneaky, "hiding" in the nooks and crannies on the biting surfaces of teeth, around the gum line and in between teeth.
So, how do you know if you're clearing out any plaque holdouts? An effective way is to use a plaque disclosing agent. This over-the-counter dental product consists of a swab, tablet or solution, which contains a dye that's reactive to plaque.
After brushing and flossing as usual, you apply the solution to your teeth for about 30 seconds. You then take a look in the mirror: Any remaining plaque will be stained a bright color that makes it stand out. There are also agents with two colors of dye, one that stains older plaque and one for newer plaque.
The plaque staining not only helps you see how well you've been brushing and flossing, it can also show you areas in need of improved hygiene. For example, if you notice a scalloped pattern around the gum line, that may mean your brush isn't getting into that area effectively. In this way, you can use a disclosing agent to fine-tune your hygiene.
Repeated use of a disclosing agent is safe, but just remember the dye color can be vivid. It does wear off in a few hours, though, so perhaps schedule it for a day off around the house. You should also avoid swallowing any solution or getting any of it on clothing.
The ultimate test, though, is a thorough dental cleaning with your dentist at least every six months. They can verify whether you've been fairly successful with your brushing and flossing, or if you have room for improvement. If you do use a disclosing agent, you can also discuss that with them in working out better strategies to protect your teeth from tooth decay and gum disease.

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.

If you like conundrums like "Which came first? The chicken or the egg?", then you may enjoy this one: "Which should you do first, brush or floss?"
Both of these oral hygiene tasks are equally important for removing dental plaque, a thin bacterial film that forms on teeth after eating. Removing plaque on a daily basis minimizes your risk for developing tooth decay or periodontal (gum) disease, the top causes for tooth loss. Brushing removes plaque from broad tooth surfaces, while flossing removes it from between teeth where brushing can't reach.
There is wide consensus that you need both brushing and flossing to thoroughly remove plaque. But there is a debate over which of these two tasks you should do first for the most effective outcome. Those debates are more or less good-natured, but there are proponents on both sides on which task should come first.
Those on the "Brush First" side say brushing initially gets the bulk of accumulated plaque out of the way. If you floss first, you may be plowing through a lot of soft plaque, which can quickly turn your floss into a gunky mess. More importantly, you may only be moving plaque around with the floss, not actually removing it. By brushing first, there's less plaque to deal with when flossing.
"Floss First" folks, though, say flossing before you brush loosens plaque stuck between teeth that can be more easily brushed away. But perhaps a more important reason is psychological: People don't really like flossing as much as brushing. Because of this, putting it off to the end may mean it doesn't happen; doing it first will help ensure it actually gets done.
In the end, though, the order you perform these tasks comes down to personal preference. You can try both ways to see which one suits you best. The important thing, however, is that you do both tasks—if you do, you can greatly lower your risk of dental disease that could rob you of your teeth.
