ATeensMissingToothMayRequireaTemporaryReplacement

Besides reduced biting and chewing function, a missing tooth can cause an embarrassing inhibition to healthy social interaction. This can be especially so for teens who greatly value peer relationships and acceptance.

Be that as it may, we typically discourage a permanent replacement for teens with a missing tooth, particularly dental implants. While we value a patient’s psychological needs, the long-term effect on dental health may be too great to advise otherwise.

The effect we’re concerned with involves jaw growth and development. Although a person’s permanent teeth have usually all erupted by early adolescence, the jaws continue to grow until the late teens or early twenties. Natural teeth can adapt to this growth because the periodontal ligament that holds them in place allows for incremental tooth movement. The teeth move in response to jaw growth and are thus able to maintain their proper relationship and alignment in the jaw as growth occurs.

Dental implants, on the other hand, are imbedded into the jaw bone: they, therefore, can’t move like natural teeth and thus can’t adjust their position with jaw growth, particularly the upper jaw as it grows forward and down. This can result in the implants appearing as though they are left behind or retreat into the jaw. It can also affect the position of the gums and inhibit their growth around the implants.

It’s best then to hold off implants and other permanent restorations until the jaw has finished developing. That, however, isn’t always easy to determine: specialized x-ray diagnostics may help, but it’s not an exact science. Your input as a parent will also be helpful, such as whether you’ve noticed the end of growth spurts (not changing clothes or shoe sizes as often) or your child’s recent similarity in appearance to other adult members of your family. It thus becomes a judgment call, based on examination and experience, as to whether it’s safe to proceed with implants — and may require erring on the side of caution.

In the meantime, there are temporary restorations that can improve appearance while you wait for the appropriate time to undertake a permanent restoration. Two of the most useful are removable partial dentures (RPDs) or a bonded bridge, a less invasive form of the traditional bridge. With a proper assessment we can advise you on which option is your best choice.

Tags: IV Sedation  

When you're having certain procedures performed at the dentist’s office, you and your dentist must decide on the appropriate sedation method. Sedation relaxes the nerves so that you don’t feel pain or discomfort while in the dentist’s chair.

One option offered by Gary W. Machiko, DMD in Pittsburgh, PA, is IV sedation. So what is IV sedation, and why might your next visit to your Sedation Dentistrycosmetic dentist include it?

What Is IV Sedation?
IV (intravenous) sedation is a way to relax a dental patient using medication injected into the bloodstream. The medication immediately begins to relax you until you’re woozy and a bit sleepy. Patients often report that hours go by and they don’t remember anything from the procedure, which is why this is a preferred sedation method for people who have severe dental anxiety.

Getting Sedated
IV sedation is most common when your Pittsburgh, PA cosmetic dentist has to perform major procedures, like implants, tooth extractions, periodontal surgery and root canals. Your dentist must give you a thorough examination and go through your medical history to ensure that you’re a good candidate for IV sedation. If you are, you must bring a trusted friend or family member along with you to your appointment, to assist with your recovery and transportation home.

After the Procedure
After undergoing IV sedation, you'll need some time to recover in the office and return to consciousness. You and your companion will be given clear aftercare instructions—you should have someone with you until you regain full alertness. It’s best to stay on bed rest for the remainder of the day and take any medications prescribed by your dentist.

Get the Dental Treatment You Need
The great thing about IV sedation is that it allows you to get the dental care you need without worrying about pain, discomfort or anxiety. Call your cosmetic dentist Dr. Gary W. Machiko today at (412) 367-1319 to set a date and time to visit his Pittsburgh, PA office.

BillRancicsSmileHelpsClosetheDeal

Can having a great smile help land you a high-level business position, a TV show, and a bride? Maybe — at least if you go by the example of Bill Rancic.

The 42-year-old Chicago native is well known as the first winner of NBC-TV's The Apprentice, a reality show where contestants vied for a job with Donald Trump's organization. Shortly after his selection as Trump's newest hire, Rancic met his future wife, Giuliana, when she interviewed him for E! News. Flash forward a few years, and the couple is now hosting their own reality TV show on Style network.

So how much has Bill's winning smile helped?

“I think a great smile says a lot about a person — especially in our professions,” Bill recently said in an interview with Dear Doctor magazine. He also mentioned that having a few cosmetic dental treatments helped him close the deal.

As a child, Bill wore braces to correct an overbite. For both kids and adults, orthodontic treatment is often the first step toward getting the smile of your dreams. The practice of orthodontics has changed dramatically in the past 20 years and there are now a number of choices available in lieu of traditional metal braces.

Not Your Father's Braces
For those who need to maintain a “professional” image, tooth-colored braces offer a less noticeable way to straighten your teeth. Lingual braces are another option that's suitable in some situations. These are truly invisible: bonded on the tongue side of the teeth, they can't be seen from the front.

Or, you may be able to forego braces altogether and use a series of clear plastic aligners to gradually bring your teeth into alignment. Not only are these difficult to notice, but they can be completely removed for short periods of time — at important board meetings, for example.

Red-Carpet Tooth Whitening
More recently, Rancic had tooth whitening treatments. Depending on the degree of lightening needed, these can range from custom-fitted bleaching trays that you wear at home under the supervision of a dentist, to in-office whitening treatments that work in far less time. Both can be effective in lightening your teeth by six shades or more.

But if you need the ultimate in whitening, veneers may be the best option. These are fingernail-thin coatings, made of pearly-white porcelain or composite material, that are placed directly on the tooth surfaces. Realistic and durable, they can provide a “Hollywood white” smile that's ready for the red carpet.

Did Bill's cosmetic dental work really improve his life? We can't say for sure — but as his wife Giuliana recently told Dear Doctor, “First impressions are very important, and having a beautiful smile will help anyone make a great impact on others.” So perhaps it worked on her!
