If you have a busy life, you probably don't want to spend more time than necessary in the dentist's office. Luckily, CEREC crowns and dental crownsrestorations offer same-day results. Dr. Jeffery Johnson and  Dr. Jody Johnson in St. Louis, MO, discuss the CEREC difference.

No more temporary crowns

When you receive a porcelain crown, one visit must be dedicated to preparing your tooth and taking an impression of your mouth. Because your new crown must be created in a dental laboratory, you'll need to cover your tooth with a temporary crown while you wait for the lab to complete the permanent crown. In most cases, you'll wait two weeks or more until you can receive your new crown and must return to the office for another appointment.

CEREC crowns only require one visit. During your visit to Drs. Jeffrey and Lori Johnson's St. Louis office, your tooth will be prepared and an impression of your teeth will be made. The CEREC system uses digital images to make impressions. After uploading the image to the CEREC software program, the dentists will have all the information they need to design your new crown.

Once the crown is ready to be produced, the design information will be sent to a milling machine located in the office. The machine takes a block of ceramic and creates a crown that blends in with the rest of your smile perfectly. In just about a half-hour after your impression is made, you'll have a brand new crown.

Not just crowns

The CEREC system can also be used for other restorations, such as inlays, onlays and veneers. Inlays and onlays are used when you need a very large filling. Inlays fit inside the edges of your teeth, while onlays extend beyond them. These restorations are usually created in a lab, but thanks to CEREC, they can now be made dental offices. Since CEREC inlays and onlays are tooth-colored, no one will even know that you have a filling. CEREC can also be used to design and create veneers, thin, tooth-shaped shells that are attached to the fronts of teeth to cover flaws.

Could you benefit from a CEREC crown or restoration? Call Drs. Jeffrey and Lori Johnson in St. Louis, MO, at (314) 427-7400 to schedule your appointment.

ConsciousSedationcanHelpEaseYourChildsDentalVisitAnxiety

The best way to prevent dental visit anxiety in your children is start those visits around their first birthday, and continue with them through childhood. Age One visits are the best way to ensure they're comfortable with the dentist now and that they'll continue the habit into adulthood.

But in spite of your best efforts and those of your dental provider, there's no guarantee your child won't experience dental visit anxiety at some point. If that happens, we recommend conscious sedation.

Conscious sedation is the use of certain medications to help a patient relax. It's not the same as anesthesia, which eliminates pain by numbing tissues (local anesthesia) or inducing unconsciousness (general anesthesia). During conscious sedation a patient remains awake or at the most in a dream-like state, can still respond to touch or verbal commands, and although monitored doesn't require assistance in heart or lung function.

We can induce this relaxed state in a number of ways: orally, with medication given by mouth a short time before the visit; intravenously, the medication delivered through a drip directly into the bloodstream; or by inhalation, usually nitrous oxide gas mixed with oxygen and delivered by mask.

Oral sedation is the most common. On the day of the procedure, we'll give your child one or more sedative drugs, usually in syrup form. For best results we advise they eat a low-fat dinner the night before and not eat or drink any food or liquid afterward. We typically use Midazolam and Hydroxyzine, both of which are proven safe and fast acting.

During the procedure, we'll also assign a team member to monitor their vital signs while they're under the influence of the drugs. We may also employ special positioning or immobilization equipment to keep movement to a minimum.

After the procedure, we'll continue to monitor vitals until they return to pre-sedation levels. The child should remain home the rest of the day to rest and return to school the next day.

Conscious sedation is regulated by states: providers must be trained and licensed to administer sedation drugs with continuing education requirements. Even so, the use of sedation for children is becoming more widespread and helps to safely ensure they're getting the dental care they need.

If you would like more information on comfortable dentistry for children, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Sedation Dentistry for Kids.”

VivicasVeneerstheMakingofaHollywoodSmile

What's an actor's most important feature? According to Vivica A. Fox, whose most recent big-screen role was in Independence Day: Resurgence, it's what you see right up front.

"On screen, your smile and your eyes are the most inviting things that bring the audience in" she said. "Especially if you play the hot chick."

But like lots of people, Vivica reached a point where she felt her smile needed a little help in order to look its best. That's when she turned to a popular cosmetic dental treatment.

"I got veneers years ago," Ms. Fox told Dear Doctor magazine in a recent interview, "just because I had some gapping that probably only I noticed."

What exactly are dental veneers? Essentially, they are thin shells of lustrous porcelain that are permanently attached to the front surfaces of the teeth. Tough, lifelike and stain-resistant, they can cover up a number of defects in your smile — including stains, chips, cracks, and even minor spacing irregularities like the ones Vivica had.

Veneers have become the treatment of choice for Hollywood celebs — and lots of regular folks too — for many reasons. Unlike some treatments that can take many months, it takes just a few appointments to have veneers placed on your teeth. Because they are custom made just for you, they allow you to decide how bright you want your smile to be: anywhere from a natural pearly hue to a brilliant "Hollywood white." Best of all, they are easy to maintain, and can last for many years with only routine care.

To place traditional veneers, it's necessary to prepare the tooth by removing a small amount (a millimeter or two) of its enamel surface. This keeps it from feeling too big — but it also means the treatment can't be reversed, so once you get veneers, you'll always have them. In certain situations, "no-prep" or minimal-prep veneers, which require little or no removal of tooth enamel, may be an option for some people.

Veneers aren't the only way to create a better smile: Teeth whitening, crowns or orthodontic work may also be an alternative. But for many, veneers are the preferred option. What does Vivica think of hers?

"I love my veneers!" she declared, noting that they have held up well for over a decade.
