Adults Can Get Cavities Too
July 29th, 2026

Sure, you brush your teeth and floss regularly, so you might think you’re off the hook when it comes to the dental chair. However, it’s just as important for adults to get regular dental exams as it is for kids. Cavities are common among adults, with 92% of people aged 18 to 64 having had cavities in their permanent teeth, according to the National Institute of Dental and Craniofacial Research.
How cavities form
Our mouths are teeming with hundreds of types of bacteria. Some are helpful and maintain good health, while others are harmful. Certain types of bacteria process the sugars in food and release acid in return. Although minor decay can be naturally reversed by your body, Drs. Rottschalk, Acker, and Froidcoeur and our team at Dr. John Rottschalk Dental Group will tell you that eventually the acid wears away the enamel and creates small holes in the surface of teeth.
Cavity prevention for adults
Some people are naturally more prone to cavities than others. However, making a few lifestyle changes can dramatically reduce your likelihood of developing cavities.
- Food choices. Eating plenty of fresh fruits and vegetables increases saliva production, and reduces cavity risk. It is also important to avoid foods that get stuck in the ridges of your teeth. Candy, cookies, and chips should be eaten sparingly.
- Beverages. Most people know that drinking soda contributes to tooth decay. However, fruit juices and energy drinks also contain large amounts of sugar. Whenever possible, replace these sugary beverages with tea or water, which rinses your mouth and prevents decay.
- Fluoridated water. Fluoride is a naturally-occurring chemical that facilitates enamel growth. Most municipal water supplies are fortified with fluoride, so drinking tap water is a great way to keep teeth healthy. People with well water may use fluoridated toothpaste or other supplemental forms of fluoride to decrease cavity risk.
- Brush teeth and floss frequently. Gently brushing teeth several times a day removes the harmful bacteria that cause cavities to develop. If possible, brush your teeth after each meal or when drinking sugary beverages. Flossing regularly removes small particles that get trapped between teeth, which further decreases tooth decay.
One of the most important steps in cavity prevention is visiting your dentist at least twice a year. Consistent dental exams ensure that cavities are caught early, before they cause major damage to your teeth.

When should I begin brushing my baby's teeth?
July 22nd, 2026

One question our team at Dr. John Rottschalk Dental Group hear all the time is, “When should I start brushing my baby’s teeth?”
You should begin regular cleanings even before your baby has teeth. After each breast feeding (or bottle-feeding) use a clean, damp washcloth to gently rub your baby’s gum tissue. You may wrap the material around one finger to make it easier to remove any food bits from your baby’s mouth.
When your baby’s first tooth comes in, switch to a baby toothbrush. Look for special baby toothbrushes in your drugstore; they have just a few bristles and are very soft. There are even brushes shaped like finger puppets that fit over the tip of your pointer finger! All you need at this point is water (no toothpaste yet).
After a few more teeth appear, you may start using toothpaste, but you only need a tiny bit, and make sure it doesn’t contain fluoride for the first two years. From the beginning, have your little one practice spitting the toothpaste out after brushing. That way, he or she will already have the good habit of spitting when you switch to fluoride toothpaste, which should never be swallowed.
If you have any questions about caring for your baby’s teeth, or to schedule an appointment at our convenient Fairview Heights, IL office, please contact Dr. John Rottschalk Dental Group.
Five Reasons for Your Bad Breath
July 15th, 2026

Bad breath, or halitosis, is probably not a matter of life or death. But it can make you feel self-conscious and have a negative impact on your life. The majority of people suffering from bad breath are dealing with oral bacterial. However, there are other causes of this embarrassing problem. Learning more can help you fight this solvable problem.
Five Causes of Embarrassingly Bad Breath
- Dry Mouth. A decrease in saliva flow can be caused by several things. Most often, medication or mouth breathing are the culprits. As saliva helps wash away food particles from your mouth, it prevents bad breath. Dry mouth can be dealt with by stimulating salivation.
- Gum Disease and Poor Oral Hygiene. Not brushing and flossing well enough or with enough frequency can lead to gum disease, which leads to bad breath. Halitosis can be a sign that plaque is present on your teeth.
- Food-Related Bad Breath. Food particles that aren't brushed or flossed away attract bacteria that leads to bad breath. It's especially important to brush after eating strong-smelling foods, such as garlic or onions.
- Smoking and Tobacco. Tobacco is bad for your health, and that includes your oral health. Smoking or chewing tobacco can contribute toward the development of gum disease, as well as oral cancer.
- Mouth Infections and Other Medical Problems. A mouth infection, sinus infection or even the common cold can cause you to temporarily have bad breath. Even conditions such as diabetes and reflux can cause halitosis. It's always wise to see Drs. Rottschalk, Acker, and Froidcoeur to help determine the cause.

What Your Dentist Checks During a Checkup
July 8th, 2026

You’ve been going to Dr. John Rottschalk Dental Group for a while now, so you pretty much know what to expect when you get to our Fairview Heights, IL office.
You’ll see Drs. Rottschalk, Acker, and Froidcoeur, your hygienist, and all the other members of your friendly dental team again. You’ll sit in a comfortable chair just your size. And you’ll have a checkup to make sure your teeth are healthy.
But once you’re sitting back in that comfortable chair, you might be wondering just what exactly gets checked during your checkup. The answer is, a lot!
- Checking Your Tooth and Gum Health
It’s important to have regular checkups because finding a small problem right away, like a weak spot in your tooth enamel, means your dentist can prevent it from becoming a bigger problem, like a cavity, later!
So your dentist will carefully examine each tooth for signs of tooth decay, using a little mirror to see behind your front teeth and around those hard-to-see teeth in the back of your mouth. The visible part of your smile doesn’t always tell everything about your dental health, though. At some checkups, you might need X-rays to make sure the insides of your teeth and their roots are healthy.
Oral health means more than just your teeth. That’s why your dentist will examine your gums and the inside of your mouth, too.
- Checking Your Bite
Drs. Rottschalk, Acker, and Froidcoeur will check the way your teeth fit together when you bite, and can take X-ray images to show the size and shape of your jaw bones and the size and position of your permanent teeth before they even come in.
If your teeth and jaws fit don’t together just right, or if it looks like there might not be enough room for all your adult teeth to come in without crowding, your dentist might recommend pre-orthodontic or orthodontic treatment.
- Cleaning Your Teeth
Plaque can hide in hard-to-reach places between your teeth and around your gums. You might know that plaque can cause cavities if it’s not brushed away, but did you know that plaque can also hurt your gums? That’s why an expert cleaning is usually part of every checkup.
Your hygienist will use special dental tools and carefully remove any plaque you might have missed or any tartar (hardened plaque) that’s built up over time. Then after flossing and rinsing, you’ll have a clean, sparkling, plaque-free smile.
Bonus: Your dental hygienist can teach you how to brush and floss better if you’ve been missing a few spots!
- Can Your Teeth Use Extra Protection?
Once your teeth are cleaned and examined, your dentist might use a fluoride treatment or sealants to give your teeth extra protection against cavities.
Fluoride treatments help make your tooth enamel stronger. If your dentist thinks you need this kind of fluoride protection, your teeth will be coated with a special fluoride gel or varnish or foam. This treatment doesn’t take long and will strengthen your enamel for months afterward.
People’s molars get the most cavities because their uneven surfaces make good places for plaque and bits of food to hide from brushes. A sealant is a thin coating which is brushed on the top of your molars to prevent plaque from hurting your enamel.
- Checking In with You!
Part of your checkup is talking to your dentist about how you can protect and even improve your dental health.
- Find out whether the foods you eat make your tooth enamel stronger—or weaker.
- Discover how brushing and flossing help prevent tooth decay and gum disease, and see if your brushing and flossing skills need any work.
- Learn how to protect your teeth during active sports (hint: wear a mouthguard).
- If you have habits which can hurt your teeth, like nail biting, get advice on how to quit.
- Don’t forget to ask any questions you might have!
Your checkup might be a little different, because your exam is designed just for you, but there’s one thing which all of us can expect. Visit our Fairview Heights, IL pediatric dental office for regular checkups, work together with your dental team, and you can expect a healthier, happier smile!
