HilaryDuffsChippedFrontTeethRepairedwithVeneers

Many Hollywood luminaries use porcelain veneers to enhance their smiles. Take actress and singer Hilary Duff, who, according to People magazine, had veneers placed on her two front teeth after chipping them on a microphone during what must have been an extremely energetic performance.

Well, you don't have to be a Hollywood star to benefit from a smile enhanced with porcelain veneers. If you have small chips, cracks, slight tooth rotations or minor spacing problems, veneers may be able to give you back your smile — or an even better one.

The word “veneer” refers to a super-thin covering, and in dentistry a veneer is a thin layer of porcelain that replaces your natural tooth enamel. Porcelain is the material of choice because of its strength, translucency, and ability to resist erosion.

In the right hands, dental porcelain can mimic tooth enamel perfectly. To make veneers, a skilled dental technician will mix porcelain powder (in a shade specified by the dentist) with water and then fire the material in an oven like pottery; the porcelain is built up in layers for a truly lifelike effect.

Before a veneer is bonded to a tooth, often we need to remove a tiny bit of the tooth's existing enamel so that the final effect will not be too bulky. The procedure is virtually painless and can be completed in as little as two visits. Because enamel is removed, this particular cosmetic treatment is not reversible. Sometimes veneers can be added directly onto the tooth surface without any tooth reduction and therefore are reversible if used in this way.

Once you have veneers, please keep in mind that while extremely strong, porcelain veneers are not indestructible; you won't want to do things like crunch ice or break nuts open with your teeth. And if you are a teeth-grinder, you should wear a nightguard to protect your beautiful new smile. With proper care, your veneers will last 20 years or more.

JawSurgerymaybeNecessarytoOvercomeSomeTeethMisalignments

Orthodontics is a specialty of dentistry dedicated to the diagnosis and treatment of misaligned teeth, or malocclusions. The goal is to help patients achieve better long-term oral health by improving teeth alignment. Sometimes, though, the misalignment is much more involved than the position of the teeth — it may be that the jaw structure is also misaligned. In that case, the skills of an oral surgeon may be in order.

The jaws are similar in shape to the arch of a horseshoe, hence the referral to either upper or lower sets of teeth as dental arches. In a normal jaw structure, the lower arch fits just inside the upper arch when you bite down and the teeth are able to function correctly. In some individuals, though, the lower arch closes in front of the upper arch, commonly known as an underbite. If the underbite is only slight, the malocclusion can be corrected by repositioning the teeth only, as with braces. If, though, the underbite is more severe it would require a surgical procedure to realign the jaws, also known as orthognathic surgery.

Orthognathic surgery can help relieve a number of functional complications caused by jaw-related malocclusions: difficulty chewing and swallowing; chronic jaw or head pain; or sleep apnea. It can also enhance the patient’s facial appearance by correcting an imbalance between the two lateral sides (asymmetry), or by minimizing a receding chin or protruding jaw.

Its primary benefit, though, is its effect on the patient’s bite and tooth alignment. For this purpose, the orthodontist and oral surgeon work together to achieve the best result possible. In some cases, the orthodontist may perform his or her work first by moving teeth into the proper position. This sets the stage for the oral surgeon to perform orthognathic surgery to complete the correction of the misalignment.

Each individual patient’s case is different — the best plan of action must begin with a full examination by an orthodontist, and a consultation with an oral surgeon if necessary. It may require time and the expertise of two specialties, but the final result will be better health and a better look.

HowDentalImplantsSavedTaylorHicksSmile

If (heaven forbid) you were to lose your two front teeth in an accident, and you needed to choose a tooth replacement method, which one would you pick? Once upon a time, that question faced Taylor Hicks, the former American Idol winner who now plays a regular gig in Las Vegas. Back then, when he was a high-school basketball star, Hicks happened to receive a blow to the mouth at a playoff game. As fate would have it, he also happened to be the son of… wait for it… a dentist. So what did he do?

The down-to-earth song stylist recently told Dear Doctor magazine how, immediately after the accident, his father administered first aid, getting him back into the game before it ended. Then, a short while afterward, Hicks had the gaps in his smile fixed with dental implants.

We think he made a good choice. While there are other tooth replacement systems, none offer the benefits provided by dental implants. In case you need a reminder, here are some facts about dental implants:

  • They have the highest success rate of any tooth replacement procedure — above 95%
  • They are the most durable type of replacement tooth — with proper care, they can last for the rest of your life
  • They look and “feel” completely natural, and require no special maintenance
  • They are the only tooth replacement system that essentially stops bone loss in the jaw (a natural consequence of tooth loss), helping to maintain good oral health
  • Over the long term, they can offer the best value for your investment in dental care

What makes dental implants work so well? Unlike bridgework or other methods, lifelike implant crowns are supported by a screw-like titanium metal insert, which actually becomes fused with the bone of the jaw. This not only provides the prosthetic teeth with a rock-solid anchorage, but it also helps provide the physical stimulation that bone needs to keep itself healthy. Lacking this stimulation, the jaw bone begins to atrophy and erode (melt away) — and if left untreated long enough, it can result in the appearance of premature aging and other oral health problems.

So if you have missing teeth — whether from an accident, disease, or another cause — contact us or schedule an appointment for a consultation, and find out whether dental implants might be right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Dental Implants.”
