CrownLengtheningMightbeNecessaryforSeniorswithToothDecay

While tooth decay is a potential problem at any age, the risk increases as you grow older. Not only are senior adults more susceptible, decay is often more difficult to treat. That’s because cavities can occur at or below the gum line, often due to gum recession.

If that’s the case, we won’t be able to fill the cavity in the usual way because the gum tissue is in the way. To make it possible to treat, we may need to perform a minor surgical procedure known as crown lengthening.

As the name implies, the procedure helps expose more of the crown, the tooth’s visible part, from the surrounding gum tissue. In basic terms, we’re repositioning the gum tissue away from the biting surface of a tooth to make room for a filling. It’s also useful for improving a tooth’s appearance by making it look longer, or creating room for a crown or other dental restoration.

After applying a local anesthesia, the dentist (or periodontist, a specialist in the gums) creates a tiny flap of gum tissue with a series of incisions. This allows the dentist to move the affected gums out of the way to access the underlying bone. The dentist then reshapes the bone to adequately support the gum tissue when it’s finally repositioned to expose the crown. In its new and improved position, the dentist sutures the gum tissue in place.

For a few days afterward, the patient will need to restrict their diet to soft foods, avoid strenuous activities and apply an ice pack to help reduce swelling the day of surgery. They will also prescribe a pain reliever and possibly an antibiotic to reduce the chances of infection.

While most people return to normal activities a few days later, you’ll usually have to wait a few weeks for the gums to heal before undergoing any further treatments for the affected teeth. But even with the wait, crown lengthening could make it possible to not only save your tooth but improve your smile as well.

ANewResolution-Floss

Now that we’re into the New Year, it’s a good time to look over your list of resolutions. Did you remember to include dental health on your list? Here’s one simple resolution that can help keep your smile bright and healthy through the New Year and beyond: Floss every day!

Your oral hygiene routine at home is your first line of defense against tooth decay and gum disease. While brushing your teeth twice a day effectively removes much of the food debris and dental plaque from your teeth, brushing alone is not sufficient to remove all the plaque that forms on your teeth and around your gums. For optimal oral health, flossing once a day is also necessary.

Which teeth do you need to floss? Any dentist will tell you, “Only the ones you want to keep!” And yet according to a national survey of over 9,000 U.S. adults age 30 and older, nearly 70% don’t floss every day, and nearly one third admit that they don’t floss their teeth at all. Unfortunately, if you don’t floss, you’ll miss cleaning about a third of your tooth surfaces. When plaque is not removed, this sticky film of bacteria releases acids that cause cavities and gum disease. With dental floss, however, you can clean between the teeth and around the gums where a toothbrush can’t reach.

Flossing is an essential component of good oral hygiene. Still, daily flossing seems to be a harder habit to get into than brushing. Some people tense up their cheek muscles while flossing, making it harder to comfortably reach the back teeth, so remember to relax as you floss. If unwaxed floss doesn’t glide easily between teeth, try waxed floss. If you have trouble using traditional dental floss, you can try threader floss, which has a rigid tip, interdental brushes, floss picks, or a water flosser, which cleans by way of pressurized water.

It’s not too late to add one more resolution to your list, and flossing is a habit that will go a long way toward keeping you in the best oral health. And along with good dental hygiene at home, regular professional dental cleanings and checkups are key to a healthy smile. If you would like more information about maintaining excellent dental health, please contact us or schedule a consultation.

FlossingDailyAroundImplantswillHelpPreventLosingYourBridge

Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.

Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.

To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.

This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.

To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.

You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.

You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.

Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.

If you would like more information on implant-supported bridges, 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 “Oral Hygiene for Fixed Bridgework.”

Dental VeneersA survey released by the American Association of Orthodontists found that about a third of Americans admit that they wish they had better-looking teeth. The quality of your smile has professional, social, and personal ramifications. Could your teeth benefit from veneers? After one visit to Kenneth Woo, DDS and Associates in Kensington and Gaithersburg, MD you’ll know exactly what dental veneers can do for you and your smile.

Dental Veneers Hide Imperfections
Your teeth can be perfectly healthy except for visible imperfections on the outer enamel. Veneers hide these imperfections, no matter how unsightly they may be. Though a veneer is made of ultra-lightweight, translucent porcelain, the dental bonding agent used is colored to perfectly match your other teeth. Even dark, discolored, and chipped teeth can look smooth, white, and brand new with veneers.

Dental Veneers Protect
Porcelain is a high-quality ceramic material that is made through a special heating process. It is very durable and resists cracking or chipping. The toughness of the material gives your front teeth a certain level of protection for as long as the veneers are installed. However, it’s still a good idea to wear a mouthguard created by your Kensington or Gaithersburg, MD dentist whenever possible so that the veneers and your teeth have an additional safeguard. This is especially true if you have a tendency to clench your teeth or you participate in sports.

Dental Veneers Save Time
In order to change the positioning of your teeth for an ideal alignment, you would have to wear braces for at least a year or two and visit the dentist about every month. Veneers only take about a month for installation and you’ll only have to attend about two or three total appointments. Furthermore, each appointment with your dentist will only take about 45 minutes to an hour. You won’t have to wait very long to show off your smile to the world!

You don’t have to continue to be dissatisfied with your smile when you have a good cosmetic dentist on call.
