Telltale Signs that Your Tooth has a Cavity

January 21st, 2026

Drs. Rottschalk, Acker, and Froidcoeur and our team at Dr. John Rottschalk Dental Group frequently get questions about cavity causes and prevention. You brush twice a day and floss regularly. You rinse with mouthwash, just like the dentist recommended. In fact, you can’t remember the last time you had a cavity, but you think it was when you were a little kid. In all seriousness, you thought only kids got cavities.

The Signs and Symptoms of a Cavity

It’s believed that roughly 90% of North Americans will get at least one cavity in their lifetime. Those other ten percent, it seems, can eat as much pie, cake, and sugary cereals and sweets as they want. That’s not really true; just a stab at dental humor, and it was as bad as the pain your cavity is probably giving you.

When a cavity is in its initial stages, you will often be symptom-free and experience no discomfort at all. It’s not until the tooth decay has reached a certain level that you will begin to notice the signs and symptoms. While a toothache and sensitivity to hot and cold foods and liquids are surefire signs that you have a cavity, there are lesser-known symptoms as well. If you’re experiencing any of these warning signs, you may want to consider making an appointment with our office as soon as possible:

  • Persistent bad breath or a bad taste in the mouth
  • When you bite down, there is a sticky, tarry feeling
  • Puss or discharge around a tooth
  • A visible discoloring, usually black or brown
  • Small pits or holes in the tooth

Routine dental care is important. While good oral hygiene, a healthy diet, and regular cleanings will deter the formation of cavities, they do not constitute a foolproof practice. A cavity can occur at any time, no matter what your age. Bacteria causes tooth decay, and no amount of brushing, flossing, and rinsing will eradicate all the bacteria from your mouth. If you think you may have a cavity, please contact our office immediately.

What is hand-foot-and-mouth disease?

January 14th, 2026

Hand-foot-and-mouth disease, or HFMD, is a type of contagious viral illness that causes a rash in the mouth and on the hands and feet of infants and young children, and, while rare, adults. Characterized by sores in the mouth and a rash on the hands and feet, hand-foot-and-mouth disease is most commonly caused by a coxsackievirus, a bacterium that lives in the human digestive tract. HFMD can spread from person to person, typically via unwashed hands.

What are the symptoms of HFMD?

Symptoms of HFMD usually begin with a fever, sore throat, poor appetite, or general malaise. A couple of days after the fever starts, kids may develop painful sores in the mouth. A skin rash characterized by red spots may also develop, usually on the palms of your child’s hands and soles of their feet. It’s important to note some children may only experience a rash while others may only have mouth sores.

Is HFMD serious? Should we be concerned?

Usually not. Nearly all children infected recover anywhere between seven to ten days without medical treatment. Rarely, however, a child can develop viral meningitis and may need to be hospitalized. Other rare complications of HFMD can include encephalitis (brain inflammation), which can be fatal.

How can my child prevent HFMD?

There is no known vaccine to defend your child against HFMD. However, the risk of your child contracting the disease can be reduced by:

  • Making sure your child washes his or her hands often
  • Thoroughly cleaning objects and surfaces (these include doorknobs and toys)
  • Making sure your child avoids close contact with those who are infected

What's the best dental floss?

January 7th, 2026

Dental floss is similar to a lot of products that depend mainly on the consumer’s preference. Fact is, floss comes in a wide variety of flavors, coatings, and other variations, but all types of floss essentially do the same thing. After all, that is what is most important: that the dental floss you buy is functional—cleaning the areas in between your teeth. If you want to know what the best dental floss is, the answer is the kind that enables you to successfully and regularly clean those areas. So to help you find the right type of floss for you, here are some options.

Flavored Dental Floss

Many people that floss prefer a flavored dental floss because it freshens their breath even more than unscented floss. The latter can also take on the smells associated with bacteria in your mouth. And we all know how bad that can be. So, if flavored dental floss is what you prefer, and it allows you to floss your teeth regularly, then it is automatically best for your mouth.

Flossers

There are also products on the market called flossers, which usually consist of a plastic instrument with strung floss and a pick on the opposite end. This option can be both effective at cleaning the areas in between your teeth and scraping off plaque. These flossers also come flavored in mint and various other varieties.

Gentle Dental Floss

Some people find that typical dental floss is too harsh on their gums. For that reason some companies make floss with soft coatings that are less abrasive on the gums. For the most part these types of floss are just as effective as regular floss, and for those people that require a more sensitive approach to flossing, especially when just starting out, this is the best option.

Of the aforementioned options, it is difficult to name an absolute best type of floss. However, Drs. Rottschalk, Acker, and Froidcoeur and our team say that the type of floss that works best for you, giving you the greatest chance of succeeding at regular flossing, is the best.

Three Classic New Year’s Resolutions for Your Dental Health —and Three Which Might Surprise You!

December 31st, 2025

Whether you’re using the latest note-taking app or old-school pen and paper, it’s a good time to start jotting down your resolutions for a healthier, happier New Year. To help the process along, we have some suggestions for traditional tooth-friendly resolutions—and also some ideas which might surprise you!

The Classics

  • Brush and Floss Regularly

If you’re sticking to the “two minutes twice a day” brushing schedule as well as flossing once a day, great work! Often, though, that two-minute window starts to shrink as our brushing routine becomes *too* routine. Try timing yourself while you brush normally. If you’re falling quite a bit short of two minutes, taking just a bit more time will be lots more effective in removing plaque from your teeth.

And since gum disease is a leading cause of tooth loss in adults, commit to flossing once a day to remove irritating plaque and bacteria from between teeth and around the gumline.

  • Use Fluoride Toothpaste

Fluoride toothpaste doesn’t just help prevent cavities by cleaning away plaque and food particles. It also helps make our enamel stronger. 

Acids created by plaque bacteria and acids in our diet dissolve minerals from tooth enamel, making it softer and more vulnerable to cavities. Fluoride bonds with the minerals in enamel to create an even stronger protective enamel coating. Check with Drs. Rottschalk, Acker, and Froidcoeur or the American Dental Association’s website for the best toothpaste choices for healthy, strong enamel.

  • See Your Dentist Regularly

Dentists typically recommend a full dental exam and cleaning twice each year. Your dental team at Dr. John Rottschalk Dental Group will take X-rays as needed, examine your teeth, gums, and general oral health, and screen for oral cancer. A professional cleaning will remove any built-up plaque and tartar, which is especially important for gum health.

Being proactive with your dental care means you’ll be sharing your healthy smile all year long—as well as discovering any potential problems before they can develop into major problems!

The Surprises

  • Chew (Sugarless) Gum

When you’re not producing enough saliva, you feel the effects of dry mouth, including sore throat, difficulty swallowing, and bad breath. Another side effect? Poorer dental health. 

Saliva helps neutralize the acidic foods we eat, washes away bacteria and food particles, and contains minerals like calcium and phosphorus which remineralize tooth enamel. Chewing sugarless gum encourages saliva production. If you suffer from dry mouth, check with your dentist to see if chewing sugar-free gum can help.

  • Don’t Brush Right After Eating

Brushing after a meal is great to remove food particles like sugars and carbs which stick to our teeth—and which the bacteria in plaque thrive on. But if you’ve been eating or drinking acidic foods, it’s best to wait about an hour before brushing. 

Acids in foods, like acids created by bacteria, weaken tooth enamel. Brushing right away can be abrasive and damage enamel, but if you wait for an hour, the minerals in saliva have a chance to remineralize and restore your enamel strength.

  • Toss Your Toothbrush

Not that we mean give up brushing altogether! But your toothbrush bristles start to fray and fan out after several months, meaning that you won’t be getting the full cleaning effects of your great brushing technique. Put a note on your calendar to replace your brush every three to four months for the best in plaque removal.

If you’re already following all these suggestions for protecting your dental health, resolve to keep up the good work! If not, give these easy-to-follow recommendations a try. Protecting your dental health is essential to gift yourself a new year filled with happy, healthy smiles in Fairview Heights, IL.
