Understanding Cavities

June 10th, 2026

Getting a cavity seems like delayed punishment for eating that special dessert every weekend or for the few days you forgot to floss. When you are doing everything right with minimal exception and a cavity is diagnosed, it is discouraging. Knowing how cavities form and what causes them is valuable in knowing how to prevent them. In this blog post, Drs. Rottschalk, Acker, and Froidcoeur will help you understand cavities!

A cavity is not a one-time event. It is actually a symptom of a disease called caries. Tooth decay is a result of an active infection and condition in the mouth. There are ingredients to this infection, which include bacteria, acid, your tooth, and a food source. The main bacterial culprit is S. Mutans. Bacteria live in a housing structure called biofilm. This offers them protection, food, and an ideal replicating environment.

Biofilm can be healthy if there is a balance of good bacteria. When you have caries, the numbers of “bad” bacteria increase and produce an environment where they thrive and therefore cause tooth decay. A main indicator of this is a pH measurement of your saliva.

Several factors can influence the biofilm pH. Foods and beverages all have different pH levels. The lower the number, the higher the acidity. Since acid promotes tooth decay, a beverage like soda will promote a cavity. Water, being neutral, is a good choice to promote healthy oral pH. Healthy eating can still cause cavities. Here is an example of a highly acidic, yet traditionally healthy meal:

Toast with store-bought strawberry jam, and a cup of cottage cheese topped with fresh cranberries.

Instead, here is a better choice, which involves mixing acidic healthy foods with alkaline (non-acidic) foods to reduce the overall pH:

Toast with almond butter, and Greek yogurt topped with fresh blueberries.

The first example will result in a very low pH in the mouth and even in the rest of the body. The second meal mixes highly acidic blueberries with an alkaline Greek yogurt. Dairy products from cows are highly acidic. Toast is acidic because of the yeast and almonds are alkaline.

A natural buffer is saliva. Whenever mouth breathing or medications compromise the saliva flow, the pH is going to drop and caries can go rampant. Getting a cavity is not just about the sweets or forgotten flossing sessions. It is about the pH levels and bacterial management.

Warming Up for Summer Weather

June 3rd, 2026

The barbecue’s fired up. T-shirts and shorts are back in style. Sandy beaches and sidewalks are sizzling. Summer’s officially here, and it’s time to get back into hot weather mode. This means getting back into some healthy summer habits.

Be Ready to Hydrate!

Warm weather can lead to dehydration before you know it. And water does more than hydrate—it rinses away food particles after eating or snacking, neutralizes enamel-eroding acids in the mouth, and helps us keep up healthy levels of saliva. 

  • A reusable water bottle is a summer shopping list must. When you’re out walking, hiking, exercising, or camping, you can’t always be sure you’ll have fresh water available. Fill your water bottle before you leave home—you’ll help yourself stay hydrated, save money, and protect the environment, too!
  • Go light on the sports drinks and sodas when planning your summer menus. They’re often filled with sugars and acids—two very unhealthy ingredients for your teeth. 

Restock Your Sunscreen

Sunscreen helps protect skin of all shades and all ages. Exposure to ultraviolet rays is known to cause skin cancer and premature aging. Lip tissue is thin and delicate, especially at risk from the sun’s damaging UV rays. 

  • Check your sunscreen for its expiration date. Protective sunscreens and lip balms lose effectiveness once that date has passed.
  • Some sunscreens are designed for use on lips. If yours isn’t, look for a protective lip balm. All of your sunscreens and balms should have an SPF (Sun Protection Factor) of 30 or higher.
  • Bring your sunscreen and balm with you when you’re out and about, and reapply every two hours, or sooner if you’re eating, drinking, or getting wet.

Prep for Summer Adventures

If you’re travelling this summer, make sure the right dental supplies are part of your gear. A travel size toothbrush and toothpaste, a well-ventilated toothbrush case, dental floss, and your dentist’s emergency contact information are basic necessities. Once you have the basics, you can tailor your kit to your summer plans:

  • Flying? Make sure every liquid, gel, or aerosol you’ll need is the proper size for carry-on flight rules, 3.4 oz (100 ml) or less. Toothpaste and mouthwash are included in these categories, so look for travel sizes in your favorites. 
  • Going overseas? Don’t forget plug adaptors or voltage converters if needed for your electric toothbrush.
  • Camping? An emergency kit with cotton rolls, over-the counter pain relief, oral pain relief gel, dental wax (for damaged braces or a broken tooth), and even temporary fillings and a tooth preservation kit can be crucial in case of unexpected dental injuries.

Make Sure Dental Care Is on Your Summer Calendar

Laid-back summer days are the best, but laid-back dental care really isn’t! Follow your healthy dental routine even during the lazy days of summer.

  • Keep up with your brushing and flossing—brush two minutes twice each day with a fluoride toothpaste, and floss at least once a day.
  • If you’re planning a trip, don’t ignore warning signs. If you have tooth pain or sensitivity, see your dentist to treat any problems before you’re cruising at 30,000 feet or enjoying a remote campout miles from anywhere.
  • Make sure you keep up with your scheduled exams and cleanings. That’s the best way to ensure year-round dental health!

Whether you’re basking in the warm outdoor weather, relaxing in the shade with a cool drink and a good book, on the road to adventure, or wherever your summer plans take you, we hope these easy tips will help you create a summer filled with bright, healthy smiles.

Cleaning Your Baby’s Teeth

May 27th, 2026

In the eyes of most parents, nothing is cuter than their baby’s smile. Did you know your little one’s smile (that is, his or her oral health) actually plays a huge role in determining the child’s overall well-being? In order to keep your youngster healthy and smiling, you need to know when and how to take care of those tiny teeth.

Baby teeth aren’t just temporaries that will fall out eventually. They help your baby chew and talk, and they reserve space in the jaw for permanent teeth later on. Since they’re so important, the right time to start dental care is only a few days after your infant is born.

Take a soft, wet washcloth or piece of gauze and gently wipe your baby’s gums. The earlier you begin, the more accustomed your child will become to a daily dental hygiene routine.

Babies that are put to bed with a bottle may be at greater risk for developing cavities. Milk, juice, and any other drinks that contain sugar instigate tooth decay while the child sleeps.

If your baby must go to bed with something, a bottle of water is the healthiest option. Remember to wipe your little one’s gums after each feeding, whether it’s formula from a bottle or breast milk.

As soon as your infant’s first tooth comes in, it’s time to start brushing! Twice a day, take a small amount of toothpaste (about the size of a grain of rice) and brush your son or daughter’s teeth gently in circular motions. As soon as your toddler has multiple teeth that touch one another, floss up and down the sides of the teeth to remove any plaque between them or below the gumline.

Babies’ teeth are prone to cavities and gingivitis, so you’ll want to be on the lookout for telltale signs. Check regularly for red, swollen gums, because this may be an indication of developing gum disease. Discoloration, white spots, or small pits in the teeth can signal a forming cavity.

As long as you follow these simple guidelines and schedule regular dental checkups with Drs. Rottschalk, Acker, and Froidcoeur at our Fairview Heights, IL office, you can help to ensure your baby has a healthy mouth. There is nothing more rewarding than seeing your happy baby’s healthy smile.

Memorial Day

May 20th, 2026

Memorial Day is not only a federal holiday in the United States, but it is a day of observance and remembrance of those who died in service. Originally known as Decoration Day, this solemn day has been marked on calendars since the end of the American Civil War as a day to commemorate both the Confederate and Union soldiers who fought and died in the war.

Marking the graves of fallen soldiers with flowers, wreaths, or other tokens has been practiced throughout history, but it wasn't until the mark of the end of the Civil War that a special day was decided upon as the one to spend in remembrance. By 1890, every state in the country was observing Decoration Day. It wasn't until 1967 when the name formally changed from Decoration Day to Memorial Day, in order to encompass all fallen American soldiers in all wars and conflicts. In June of 1968, Congress moved the official date of Memorial Day to the last Monday in May in order to create a three day weekend.

Today, while there is certainly an air of remembrance on Memorial Day, it has become more a day of spending time with family, friends, and other loved ones. This day is also heralded as the start of summer, with many schools finishing for the year around this time. Our team at Dr. John Rottschalk Dental Group remembers it as a day to take solace and remembered those lost.

Traditional observances of Memorial Day are still held, and they often involve raising the American Flag then lowering it to a half-staff position until noon, and then raising it once again to its full height afterwards. The flag is lowered to remember those who've lost their lives while in service to their country, and then it is raised to signify our willingness to not let their sacrifice be in vain.

From community parades in the Fairview Heights, IL area, backyard cook-outs, and fireworks to formal ceremonies, Memorial Day is commemorated in many different ways. No matter how you choose to spend this day, take a moment to remember those who've lost their lives in an effort to preserve our freedom.
