Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Fatigue, irritability and family complaints about snoring — all tell-tale signs you may have sleep apnea. There’s more to this condition than being grouchy the next day — the long-term effect could increase your risks for life-threatening diseases.
But how do you know if you actually have sleep apnea? And if you do, what can you do about it?
Undergo an exam by a physician trained in “sleep medicine.” Sleep apnea occurs when the airway becomes blocked while you sleep, dropping the body’s oxygen levels; your body awakens to re-open the airway. The event may only last a few seconds, but it can occur several times a night. Even so, sleep apnea is one potential cause among others for snoring or fatigue. To know for sure if you have sleep apnea you’ll need to undergo an examination by a physician trained to diagnose this condition. He or she may then refer you to a dentist to make a sleep appliance if you have mild to moderate apnea.
Determine the level of your apnea’s intensity. Not all cases of sleep apnea are equal — they can range in cause and intensity from mild to advanced, the latter a reason for concern and focused intervention. Your physician may use different methods for determining the intensity of your case: review of your medical history, examining the structures within your mouth or having your sleep observed directly at a sleep lab. Getting the full picture about your sleep apnea will make it easier to develop a treatment plan.
Match the appropriate treatment to your level of sleep apnea. If you have moderate to advanced apnea, you may benefit from continuous positive airway pressure (CPAP) therapy, an electrical pump that delivers pressurized air through a mask worn while you sleep that gently forces the airway open. It’s quite effective, but uncomfortable to wear for some people. Advanced cases may also require surgery to alter or remove soft tissue obstructions. If, you have mild to slightly moderate apnea, though, your dentist may have the solution: a custom-fitted mouth guard that moves the tongue, the most common airway obstruction, down and away from the back of the throat.
If you suspect you may have sleep apnea, see a trained physician for an examination. It’s your first step to a good night’s sleep and better overall health.

Some moviegoers have been known to crunch popcorn, bite their fingers or grab their neighbor’s hands during the intense scenes of a thriller. But for one fan, the on-screen action in the new superhero film Black Panther led to a different reaction.
Sophia Robb, an 18-year-old Californian, had to make an emergency visit to the orthodontic office because she snapped the steel wire on her retainer while watching a battle scene featuring her Hollywood crush, Michael B. Jordan. Her jaw-clenching mishap went viral and even prompted an unexpected reply from the actor himself!
Meanwhile, Sophia got her retainer fixed pronto—which was exactly the right thing to do. The retention phase is a very important part of orthodontic treatment: If you don’t wear a retainer, the beautiful new smile you’re enjoying could become crooked again. That’s because if the teeth are not held in their new positions, they will naturally begin to drift back into their former locations—and you may have to start treatment all over again…
While it’s much more common to lose a removable retainer than to damage one, it is possible for even sturdy retainers to wear out or break. This includes traditional plastic-and-wire types (also called Hawley retainers), clear plastic retainers that are molded to fit your teeth (sometimes called Essix retainers), and bonded retainers: the kind that consists of a wire that’s permanently attached to the back side of your teeth. So whichever kind you use, do what Sophia did if you feel that anything is amiss—have it looked at right away!
When Black Panther co-star Michael B. Jordan heard about the retainer mishap, he sent a message to the teen: “Since I feel partly responsible for breaking your retainers let me know if I can replace them.” His young fan was grateful for the offer—but even more thrilled to have a celebrity twitter follower.

Most of us wouldn't think of buying a new car without a “test drive.” It's a serious investment, so you want to make sure you're comfortable with your new ride.
Like an auto purchase, the plan you and your dentist agree on to cosmetically enhance your teeth and gums — a “smile makeover” — is a significant investment. Wouldn't it be nice to “test drive” your future smile before you undergo any procedures?
Actually, you can — two ways, in fact. For one, your dentist could use computer imaging software that alters a photo of your face to show how your smile will appear after dental work. These computer enhancements are a great planning tool for making decisions on the look you want to achieve.
But even the best computer images only provide a static, two-dimensional representation of your new smile. It can't capture all the angles and movement dynamics of any proposed changes. That's where the other way, a trial smile, is a true test drive — you can see your future smile in action.
With a trial smile, your dentist temporarily places tooth-colored material called composite resin on your teeth to simulate the proposed changes. The resin can be shaped and sculpted to create a life-like replica that you'll be able to view in all three spatial dimensions. What's more it will give you a chance not only to see what your new smile will look like, but to actually experience how it feels in your mouth.
Creating a trial smile is an added expense and it's only available during your consultation visit — the dentist will need to remove the resin before you leave. But you'll still be able to get a good impression of what your final smile will be like. You'll also be able to take photos you can show to family and friends to get their impressions of your proposed new look.
A trial smile allows you to know beforehand what your dental work investment will provide you, and even fine-tune your makeover plan before work begins. With this particular kind of “test drive” you'll have greater assurance that you'll be happy and satisfied with the end results.

If you've lost a tooth, you have a number of options for replacing it. Perhaps the best choice in terms of lifelikeness and durability is a dental implant.
All implants have the same basic architecture: a titanium metal post imbedded in the jawbone to replace the root; and an abutment, a metal collar that links the post with a lifelike porcelain crown. But implants can vary in how the crown attaches to the abutment and post — either cemented to the abutment or screwed through the abutment to the post.
Either method will permanently secure the crown to the implant. But there are advantages and disadvantages for each.
A screw-retained crown may better facilitate any future repair that might be needed. For a skilled dentist it's a simple matter of removing the screw and then the crown from the abutment. There's less risk of damage to the implant during repairs or crown replacement. Many dentists also prefer screws for crowns placed at the same time they're installing the implant post (a procedure called immediate loading).
The screw access hole, however, could pose a cosmetic problem. Although we can cover it over with tooth-colored filling, it may still be noticeable and unattractive especially for a tooth visible when you smile (in the smile zone). There's also the possibility the porcelain around the access hole could chip.
By contrast, cemented crowns have a smooth, unbroken surface and are aesthetically ideal for smile zone teeth. But the cement could interact poorly with gum and bone tissue in some patients, causing inflammation and possible bone loss.
And unlike screw-retained crowns, cemented crowns are difficult to remove for implant repair. We may have to drill through the crown to access the screw between the abutment and the post, and then repair it cosmetically if we use the same crown. Again, the final result may not be quite as visually appealing.
In the end, it will depend on the implant's location, how your body reacts to the cement or your dentist's preference. In either case, though, you'll have a tooth replacement that's functional, life-like and able to endure for many years to come.
