Antibiotic Prophylaxis or Pre-Medication

November 26th, 2025

At Robert Scott Meuselbach DDS, 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. Meuselbach 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.

Tips for a Tooth-Friendly Thanksgiving

November 26th, 2025

Nothing is more welcome at the Thanksgiving table than your happy, healthy smile! Here are some ideas to keep your holiday smile looking and feeling its best.

#1 Good Dental Hygiene Doesn’t Take Holidays Off

Thanksgiving day is bustling with activity, with shared meals and travelling and get-togethers in West Chester. But it’s still essential to make time for proactive dental care. When foods stick around your teeth after you eat, the bacteria in plaque use those sugars and carbs to create acids which erode teeth and lead to cavities. And since Thanksgiving offers plenty of opportunities during the day to nibble on foods high in sugars and carbs, your teeth might need some extra TLC.

  • If you’re home, brush and floss as usual after eating. If you’re travelling, bring a kit with a travel-size toothbrush and toothpaste and some floss to keep your teeth clean and your breath fresh throughout the day. 
  • If you’ve been eating acidic foods like cranberry sauce, wine, or sodas, wait about 30-60 minutes to brush. Acids weaken enamel temporarily, and, until the enamel rehardens, brushing can be abrasive.
  • Hydrate with water. Water helps wash away food particles from teeth and braces and helps neutralize enamel-damaging acids in foods and drinks by encouraging healthy saliva production.

#2 Be Choosy about Your Food Choices

  • Make sure your plate has a healthy portion of protein and vegetables.
  • If your dinner just isn’t complete without carbs, try whole grain rolls instead of soft breads and sweet potatoes instead of white potatoes.
  • Eat sweets and desserts with meals, when saliva production is high. This helps wash away sugars and neutralize acids.
  • If you or your child wears braces, be sure to keep to braces-friendly foods. This means nothing crunchy, chewy, hard, or sticky.
  • Make water one of your go-to beverages. If you do drink acidic beverages such as coffee, soda, or energy drinks, don’t sip them throughout the day. This bathes the teeth in acid for long periods.
  • Chew sugarless gum if the team at Robert Scott Meuselbach DDS recommends it. Sugar-free gum encourages saliva production.

#3 Use the Right Tools When You Cook and Eat

And the right tools are never your teeth! Even when every surface in the kitchen is devoted to food prep and you can’t find the bottle opener or the nutcracker or the scissors anywhere, using your teeth to open bottles or nuts or bags of chips is a recipe for disaster. Avoid fractured and chipped teeth by using the appropriate tool for the job.

#4 See Your Dentist to Prevent Small Problems from Becoming Big Holiday Disruptions

If you’ve been suffering tooth pain or sensitivity, schedule an appointment with Dr. Meuselbach before the holidays to make sure your teeth and gums are their healthiest. Nothing takes the fun out of feasting more quickly than a dental emergency. 

Work with Dr. Meuselbach to ensure that your dental health is at its best for the holidays and every day. With proactive care, a tooth-friendly diet, and regular examinations, you’ll be welcoming friends and family with a beaming, healthy smile all year long.

What's in toothpaste and how does it work?

November 19th, 2025

Dr. Meuselbach and our team recommend that you brush your teeth two to three times a day, for at least two minutes each time. But have you ever wondered what’s in toothpaste and how it actually works? The mouth is home to more than 500 types of microorganisms that feed on leftover food that gets stuck on and around your teeth. Toothpaste is the best line of defense against all those pesky microorganisms (especially when you brush two to three times a day). Here’s how it works.

Abrasives

Toothpaste contains mild abrasive additives that combat microorganisms and fight plaque. When you brush, the abrasives in toothpaste dislodge food particles and microorganisms more effectively than if you simply brush your teeth with water. The abrasives also work to remove food stains and polish the surface of the tooth. Some toothpastes include ingredients like triclosan and Xylitol. These chemicals prevent the growth of bacteria that produce plaque. Plaque not only causes cavities, but it can also lead to more dangerous issues like periodontal disease.

Fluoride

Fluoride is key ingredient in toothpaste. As the microorganisms in your mouth feed off the leftover food particles, they leave behind acid and sulfur byproducts that wear away the enamel of the teeth. This is the fancy, technical way of saying that the acid on your teeth causes cavities. As for the sulfur byproduct –well, that’s just a fancy, scientific name for bad breath. Fluoride works to fight the acid and help protect the teeth. By brushing, the fluoride is incorporated into the tooth enamel, which in turn makes the tooth more resistant to acid and plaque.

Flavoring and Sweetening Agents

Not all toothpaste tastes the same, right? The type of flavoring or sweetening agents added to the toothpaste doesn't have anything to do with fighting microorganisms and plaque, but taste is one of the most important selling points in finding a toothpaste brand you like. Flavoring agents mask the taste of some of the other ingredients in toothpaste, and without those agents chances are nobody would be brushing their teeth two to three time a day.

Losing a Baby Tooth Prematurely

November 19th, 2025

Losing a baby tooth is often an exciting event in a child’s life. It’s a sign your child is growing up, and might even bring a surprise from the Tooth Fairy (or other generous party). But sometimes, a baby tooth is lost due to injury or accident. Don’t panic, but do call our West Chester office as soon as possible.

If Your Child Loses a Tooth

It is important to see your child quickly when a baby tooth is lost through injury. The underlying adult tooth might be affected as well, so it’s always best to come in for an examination of the injured area. The American Dental Association recommends that you find the lost tooth, keep it moist, and bring it with you to the office. Call Dr. Meuselbach immediately, and we will let you know the best way to treat your child and deal with the lost tooth.

Baby Teeth Are Important

There are several important reasons to look after your child’s first teeth. Baby teeth not only help with speech and jaw development, but they serve as space holders for permanent teeth. If a primary tooth is lost too early, a permanent tooth might “drift” into the empty space and cause crowding or crookedness.

Space Maintainer

A space maintainer is an appliance that does exactly that—keeps the lost baby tooth’s space free so that the correct permanent tooth will erupt in the proper position. The need for a space maintainer depends on several factors, including your child’s age when the baby tooth is lost and which tooth or teeth are involved. We will be happy to address any concerns you might have about whether or not a space maintainer is needed.

It is important to remember that there are solutions if the Tooth Fairy arrives at your house unexpectedly. Keep calm, call our office, and reassure your child that his or her smile is still beautiful!
