Antibiotic Prophylaxis or Pre-Medication

June 28th, 2017

At Keldsen Family Dental Care, we know the human mouth contains a lot of bacteria. A bacterium can travel through your body with routine activities that are a normal part of daily living. You spread bacteria when you brush or floss your teeth, when you chew, and when you swallow.

For most people, bacteria don’t cause any problem. For some people, however, especially those who have chronic medical conditions, specific cardiac conditions, or whose immune systems are compromised, bacteria that spreads throughout the bloodstream can lead to much more serious bacterial infections.

The goal of pre-medication or antibiotic prophylaxis, Dr. Keldsen will tell you, is to prevent bacterial endocarditis, a serious infection of the endothelial heart surfaces or the heart valves. The condition is also called infective endocarditis. A small population of people with certain health problems has a high risk for contracting this potentially deadly bacterium.

The American Heart Association states that people at greatest risk for contracting bacterial or infective endocarditis are:

  • Patients who underwent cardiac valve surgery in the past
  • Those who have suffered past incidents of infective endocarditis
  • Patients who have mitral valve prolapse, resulting in or causing valve leakage
  • People who have had rheumatic fever or any degenerative cardiac condition that produces abnormalities in cardiac valves
  • Patients who suffer from certain congenital heart diseases

For these patients, any dental procedure may cause bleeding, and prophylactic antibiotic administration is recommended as a preventive measure.

Other patients who require prophylactic antibiotics

The American Association of Endodontists extends recommendations to patients who have undergone joint replacement surgery within the past two years, suffer from type 1 diabetes, or have immune deficiencies from diseases such as lupus, rheumatoid arthritis, or HIV; cancer patients whose immune systems are suppressed because of radiation or chemotherapy; people who have had organ transplants; and hemophiliacs.

The American Academy of Pediatric Dentistry also includes people who suffer from sickle cell anemia, as well as patients who suffer from conditions that require chronic steroid therapy.

Typical endodontic procedures for which antibiotic prophylaxis is recommended include root canal therapy (when it involves going deeper than the root apex), surgical tooth extractions, and any other dental, endodontic, or periodontal procedure during which the doctor anticipates bleeding.

Although different medical societies and organizations offer these guidelines as a way of identifying patients for whom prophylactic pre-medication is essential prior to dental procedures, dentists will take each patient's medical history and personal risk factors into consideration. Some doctors may choose to administer antibiotics following a procedure, especially for patients who have previously suffered from oral infections either as a result of dental procedures or that necessitated oral surgery.

Alleviating Anxiety before Your Implant Procedure

June 21st, 2017

Does the thought of getting a dental implant put knots in your stomach? There are many people who don't enjoy getting dental work done and there is a myriad of reasons why. For whatever reason you aren't at your best when you arrive at our Bend, OR office, we'd like to offer some tips that can help put you at ease for your implant procedure.

Sedation

For lengthy visits like an implant procedure, sedation dentistry may be an option for you. With sedation dentistry you are given sedation medication, usually orally with a pill or intravenously, which allows you to drift through the entire procedure without any memory of it afterward. If you decide on oral sedation, typically you take the medication about an hour before your procedure starts.

To avoid any complications, a complete medical background check is made along with a record of any allergies before any sedation is administered. Your vital signs are also monitored throughout the entire procedure.

If you decide sedation is not the right option for you, there are other techniques that you can benefit from. Some of these include:

  • Communication: This may seem obvious, but communicating any fears or anxiety you may have about your procedure with us is extremely helpful. Not only does this build a relationship of trust but it allows us to try and alleviate your anxiety as much as we can.
  • Herbal teas: Drink some herbal tea (like chamomile or lemon balm) before you visit the office. Many patients find this is a great help in relieving anxiety and putting them sufficiently at ease.
  • Relaxing music: Bring a pair of headphones along and listen to your favorite music during treatment (preferably something low-key). Or why not catch up on your reading when you visit us — some patients like to listen to audiobooks too!
  • Meditate or practice deep breathing: Meditation and deep breathing are good to practice in general, since they relax both the body and mind. They can be effective in the case of anxiety, too!

Tooth Worms? The History of Cavities and Tooth Fillings

June 14th, 2017

Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?

The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.

The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.

Dental Fillings Come of Age

Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.

The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.

Dr. Keldsen can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our Bend, OR office so we can take the proper action to protect the health of your mouth.

Healthy Summer Foods

June 7th, 2017

It’s summer—that wonderful time of year when fresh and delicious produce abounds. Dr. Keldsen will tell you that your teeth, gums, and tissues all rely on an appropriate mix of vitamins and minerals to maintain good oral health no matter what time of year. In previous studies, nutrients in fruits and vegetables such as dietary fiber, potassium, and antioxidants have all been associated with a reduced risk for cardiovascular disease and cancers, including oral cancer.

Here are four foods we want you to enjoy this summer to ensure a healthy mouth:

Watermelons and Strawberries

Watermelons have high water content, which dilutes the affects of the sugars they contain and stimulates the flow of saliva. In addition, research shows that eating foods full of water (watermelon is 92 percent water) helps keep you satiated on fewer calories. Finally, in addition to containing skin-protecting lycopene, eating watermelon can help you stay hydrated during the summer months, which not only keeps your memory sharp and your mood stable, but also helps keep your body cool.

Strawberries are juicy and delicious, and they’re also considered a superfood. Nutrient-rich and packed with antioxidants (such as vitamin C, which can help with cancer prevention), strawberries also promote eye health, help fight bad cholesterol, and regulate blood pressure.

Apples

Did you know consuming apples can help you attain whiter, healthier teeth? It’s true. Biting and chewing an apple stimulates the production of saliva in your mouth, and in the process, lowers the levels of bacteria and other harmful acids, leading to a lower likelihood of tooth decay. Apple consumption can also boost your immune system, reducing cholesterol and helping you avoid Alzheimer’s and Parkinson's diseases. Finally, eating an apple a day has been linked to heart health, including a lower risk of death from both coronary heart disease and cardiovascular disease.

Tomatoes

Tomatoes are a delicious and healthy snack and can help you ward off cancer. The yummy red fruit contains lycopene, which helps protect your skin from sunburn. Tomatoes can also help you fight heart disease due to the niacin, folate, and vitamin B6 nutrients they contain. They’re high in crucial antioxidants, such as vitamin C and vitamin A, which work to prevent DNA damage.
