Dental implants have come a long way since their introduction thirty years ago. Unlike their predecessors, today’s implants come in various shapes and sizes that can meet the precise needs of individual patients. Crown attachment has also developed some variety.
The actual implant is a titanium post surgically imbedded in the jawbone to replace the original tooth root. The restoration crown, the visible part of the implant system that resembles natural tooth, is affixed to the implant post. There are two basic methods to attach the crown: cement it to an abutment that has been installed in the implant; or screw it into the implant with a retaining screw from the underside of the crown. In the latter case, the abutment has been built into the crown.
While either method provides years of effective service, one method may work better than the other depending on the circumstance. Screw-retained crowns require no cement and are more easily removed than cemented crowns if it becomes necessary. On the other hand, the screw access hole can be visible, although the area can be filled with a tooth-colored filling; and although rare, chips near the access hole can occur. Occasionally the screw may become loose, but tightening or replacing the retaining screw is a simple matter because of the access hole.
A cemented crown looks more like a natural tooth and so is more useful in situations where cosmetics are a factor. The cement, however, can cause inflammation and contribute to bone loss in some patients when excess cement gets below the gums. Unlike a screw-retained crown, removal is more difficult and limited.
As a rule, screw-retained crowns are normally used in areas where the screw hole is not conspicuous, such as for posterior (back) teeth. They’re also more desirable than cemented when the implant is permanently crowned at the same time it’s surgically implanted, a process called “immediate loading.”
Which method of crown attachment is best for you? That depends on the implant location and other factors we would explore during a thorough pre-implant exam. Either way, the end result will be a life-like replica of your natural teeth, and a restored, vibrant smile.

He once lived in Australia, wore his hair in a mullet, and played guitar in a band called The Ranch. Today, country music star Keith Urban looks different than he did when he started out — and it’s not just the mullet that’s changed. As before-and-after pictures show, he’s had a smile makeover. His teeth, which were dull yellow in color, and used to have a large gap in front, are now white and shiny. The gap is still there — though it has been reduced to a more modest size. How did he manage to upgrade his image, yet keep part of his signature “look” intact?
Cosmetic dentistry has a number of ways to improve the appearance of a smile like Keith’s. One is tooth whitening. It’s a simple procedure that can be done in our office or at your home; either way, it’s an effective treatment that offers great value. In-office whitening, using the most concentrated solutions under our direct supervision, will give you the fastest results. We can also prepare a take-home kit, with custom-made trays and safe bleaching gels you can use at home. You’ll get similar results, but it will take a bit longer.
Of course, whitening isn’t permanent (though it can be repeated when necessary); not all teeth can be lightened as much as you might like; and it doesn’t correct gaps or unevenness. There’s another treatment that does, however: dental veneers. These are wafer-thin coverings made of porcelain, which are bonded to the prepared surfaces of your teeth. They are available in a number of shades — from natural to “Hollywood white” — and can even hide minor chips or spacing problems. That’s why veneers are often the treatment of choice when you’re looking for a “red carpet” smile.
Perhaps the best thing about veneers is that they give you plenty of choices when it comes to designing your smile. You can choose how white you’d like your smile to be, and even fix some “flaws” — or not! So how much you choose to close that gap in your teeth is up to you… but if you’re asking our opinion, the mullet has to go.

Alternative medicines — also known as herbal or homeopathic remedies — have grown in popularity in recent decades. Because they don’t think of these remedies as “medicines,” many people will try them based on their friends’ advice or an internet search — with or without a doctor’s advice. Any herbal remedy, though, should be viewed as a real drug with real, and often significant, side-effects.
With that said, many of these alternative treatments are safe and effective if taken in an appropriate manner. Arnica Montana, a member of the daisy family, is a good example: various preparations of this herb have been found to reduce pain and inflammation caused by sprains or bruising, as well as control infection by killing bacteria. It’s also one herbal application that’s finding a home in the field of dentistry.
You can find many products containing Arnica, particularly topical applications made from the herb’s roots and dried flowers. It’s common to find Arnica in tinctures (the herb mixed in with a gel), tea infusions and a variety of ointments; the best-selling topical product is a gel containing 8% of the Arnica herb.
Many dentists are now prescribing Arnica to patients following invasive procedures like gum surgery, root canal treatment, implant surgery or wisdom teeth extraction to help reduce swelling and bruising. In this case, topical applications won’t work: directly applying a topical treatment to open mouth wounds can cause mucositis (an irritation of the lining of the mouth) and reactions in people with allergies to plants related to daisies. Dentists prescribe a programmed capsule regimen taken orally for four days after the procedure. This has been shown to lessen the length and degree of recovery time.
Any medicine, whether traditional or non-traditional, can have unintended consequences. Know the facts about what you’re taking, and be sure you consult with your doctor or dentist before trying any herbal remedy.
