LiporPalateCleftscanbeEffectivelyRepaired

About one American baby in 700 is born with some form of lip or palate cleft—and the percentage is even higher in other parts of the world. At one time this kind of birth defect sentenced a child to a lifetime of social stigma and related health issues. But thanks to a surgical breakthrough over sixty years ago, cleft defects are now routinely treated and repaired.

Oral and facial clefts happen because a child’s facial structure fails to develop normally during pregnancy. This causes gaps or “clefts” to occur in various parts of the mouth or face like the upper lip, the palate (roof of the mouth), the nose or (more rarely) in the cheek or eye region. Clefts can have no tissue fusion at all (a “complete” cleft) or a limited amount (an “incomplete” cleft), and can affect only one side of the face (“unilateral”) or both (“bilateral”).

There was little that could be done up until the early 1950s. That’s when a U.S. Navy surgeon, Dr. Ralph Millard, stationed in Korea noticed after reviewing a series of cleft photos that tissue needed to repair a cleft was most often already present but distorted by the defect. From that discovery, he developed techniques that have since been refined in the ensuing decades to release the distorted tissue and move it to its proper location.

This revolutionary breakthrough has evolved into a multi-stage approach for cleft repair that often requires a team effort from several dental and medical professionals, including oral surgeons, orthodontists and general dentists. The approach may involve successive surgeries over several years with dental care front and center to minimize the threat of decay, maintain proper occlusion (the interaction between the upper and lower teeth, or “bite”), or restore missing teeth with  crowns, bridgework or eventually dental implants.

While it’s quite possible this process can span a person’s entire childhood and adolescence, the end result is well worth it. Because of these important surgical advances, a cleft defect is no longer a life sentence of misery.

WorldCupSoccerCoach-DentistSavestheDay

If you followed the 2018 FIFA World Cup Soccer games, you probably know that one of this year’s biggest surprises was the debut of the team from Iceland—the smallest country ever to earn a chance at the sport’s top prize. But here’s something you may not have known: When he’s not on the field, the team’s coach, Heimir Hallgrímsson, is a practicing dentist! Those two skill sets might not seem like a natural fit… but they came together dramatically at a recent contest.

At a local women’s game last summer, when a player was hit and her tooth was knocked out, Dr. Hallgrímsson took immediate action. “I jumped on the pitch and put the tooth back in, took her to a dental office and fixed it,” he said.

Not everyone has the special training or ability to fix a tooth that has been damaged or knocked out—but there are some simple things that you can do to help an adult who has suffered this kind of injury. Here’s a quick run-down:

  • After making sure the person is stable and not otherwise seriously injured, try to locate the tooth.
  • Handle it carefully, without touching root surfaces, and clean it gently with water if possible.
  • Try to open and gently rinse out the mouth, and find where the tooth came from.
  • Carefully place the tooth back in its socket, making sure it is facing the right way, and hold it in place with a soft cloth.
  • If the tooth can’t be re-implanted, place it in a bag with a special preservative solution, milk or saliva, or have the person hold it between the cheek and gum—but make sure it isn’t swallowed!
  • Rush to the nearest dental office or urgent care facility.

When these steps are followed and the person receives professional treatment as quickly as possible (ideally within minutes), their tooth will have the best chance of being saved. But even if it isn’t possible to preserve the tooth, receiving prompt and appropriate care can make replacing the tooth much easier.

Having Dr. Hallgrímsson on the sidelines was a lucky break for the injured soccer player—and as a coach, just getting to the World Cup is a remarkable achievement. But you don’t need to be a coach (or a dentist) to give first aid in a dental emergency. Taking the right steps can help ensure the best possible outcome… and might even save a tooth!

Dental ImplantsSmile gaps cause a number of problems. Most obvious are the facial changes and poor self-image caused by missing teeth. Fortunately, Dr. Kenneth Woo, Dr. Edmond Woo, and Dr. Ho Kai Wang span gaps with state-of-the-art dental implants--artificial teeth custom-designed to look and operate just like real teeth. Plus, dental implants from these skilled Gaithersburg and Kensington, MD, dentists improve jaw bone density and size every time you bite and chew.

A superior choice

When you lose a tooth in an accident or suffer extensive decay or severe gum disease, you have many choices to replace it. Partial dentures or fixed bridgework are the conventional methods. However, they pose problems of extensive wear on teeth adjoining the dental appliance, they need replacement after 10 years and they simply set on top of your gums.

Dental implants are different from and superior to traditional prosthetics because implants reside in the jaw bone below the gum line. Through what scientists call osseointegration, implants preserve and even improve bone quality, avoiding the bone, gum, and facial changes associated with tooth loss.

Dental implants boast a 40- to 50-year lifespan, states the Institute for Dental Implant Awareness, making them a wise, long-term option--even for extensive tooth loss. Dental implants from your Gaithersburg and Kensington dentist can support bridges, partials, and full dentures, too.

Who can get implants?

Most healthy adults and teens whose jaws have finished growing can receive implants. A detailed dental examination and X-rays will tell if you have sufficient bone in your jaw to receive the titanium implant devices. Additionally, non-smokers and individuals who practice careful brushing and flossing habits are great candidates.

The procedure itself takes place in two stages:

  1. Implant insertion with the benefit of local anesthetic
  2. Bonding of a metal abutment and porcelain crown

Between the two stages, your dentist leaves adequate time for the implant to integrate with the jaw bone, creating a firm foundation for the rest of the appliance.

Gaps? What gaps?

Make them disappear, and enjoy wonderful oral health, function, and aesthetics, too. Explore dental implants with Dr. Kenneth Woo and his professional associates. Contact us today for a personal consultation. We have two area offices. In Gaithersburg, phone (240) 683-3833, and in Kensington, call (301) 933-1833.

3ReasonsYouShouldConsiderToothWhitening

White, translucent teeth are the hallmark of a beautiful smile. But with age or the foods we eat our teeth’s natural brightness can dim to a dingy yellow.

If this is your case, you may be able to benefit from teeth whitening techniques that brighten up your less than “pearly whites.” A teeth whitening treatment from time to time could put the dazzle back in both your smile and your self-confidence.

Here, then, are 3 reasons for considering tooth whitening to improve your smile.

You might be able to do it yourself. There are a number of home whitening options (including whitening strips) that are safe and effective to use at home. But there are a couple caveats: because your dentist can use stronger bleaching solutions they may be able to perform the procedure in less time and with longer lasting results than a home kit. Also, some forms of staining originate inside a tooth—a home kit won’t help with that kind of discoloration.

It’s safe and relatively inexpensive. Home bleaching solutions aren’t strong enough to be harmful (unless you disregard the product directions) and are usually not very costly. Your dentist uses stronger solutions but with the training and curing equipment to minimize any risk to your teeth. And compared to other cosmetic treatments, dental office teeth whitening is still a relatively inexpensive option.

Dental office whitening can be more comprehensive and precise. Another reason to opt for your dentist to whiten your teeth is the wide range of discoloration they can alleviate. They have clinical techniques for alleviating internal tooth staining, and could even combine these with treatments for external staining. Your dentist can also help you achieve the exact degree of whiteness you desire—from a more subtle, natural shade to “Hollywood Bright.”

Whitening isn’t permanent—but with a thorough application and avoiding foods and habits that contribute to staining, professional whitening effects can last up to two years. If you’re interested, see your dentist for a full dental examination for any issues that might interfere with the whitening process. From there, you’re not far from a brighter and more attractive smile.
