Understanding Cavities

July 9th, 2025

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, Dr. Kerry Olszewski 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.

How to Celebrate National Junk Food Day

July 2nd, 2025

We mark special times throughout the year to encourage better oral health, like Dental Hygiene Month, and Children’s Dental Health Month, and even National Root Canal Day! This July 21st is National Junk Food Day, and we couldn’t let it pass without some healthy ideas to help you make the best of this not-so-dentally-healthy day.

What makes junk food unhealthy? Most of the foods in this category have high levels of sugars, starches, salts, or fats, which aren’t good for your body in large quantities. When it comes to your dental health in particular, some junk foods are worse than others because they are actively destructive to your tooth enamel.

Foods like candy, cookies, doughnuts, chips, energy drinks, sports drinks, and sodas can have large amounts of sugar, starch, and acid. And a diet filled with sugars, starches, and acids puts your tooth enamel under constant attack. 

The bacteria in plaque make acids from the sugars and starches (which break down into sugars) in our diets. These acids then erode the mineral crystals which give our enamel its strength, leaving weak spots which can deepen and become cavities. A steady diet of sweet and starchy foods for you creates a steady diet of sugar for cavity-causing bacteria. 

Just like the acids produced by bacteria can erode tooth enamel, acids in food can also strip away the minerals which keep your enamel strong. Sodas, sports drinks, energy drinks, and many fruit juices are often both sugary and highly acidic, making them very damaging to tooth enamel.

So, let’s spend a few moments today to discuss how you can enjoy a bit of junk food every now and then and still take good care of your teeth.

  • Limit Sugars, Starches, and Acids

We don’t just mean limiting the number of treats you eat in a day. It’s also a good idea to limit treats to certain times as well. Eat desserts with meals, when saliva production is higher, to help wash away sugary and starchy food particles. Acidic drinks, when sipped throughout the day, are like bathing your teeth in acids. Better to drink a soda or sports drink in one sitting and drink or rinse with water after! 

  • Brush after Eating Sticky Sugary and Starchy Foods

Sticky foods filled with sugars and starches are double jeopardy for your tooth enamel. Not only are they the foods of choice for plaque bacteria, they also tend to stick to your enamel and between your teeth, giving cavity-causing bacteria more time to work. An after-treat brushing will get rid of any sugary or starchy leftovers as well as removing built up plaque.

  • —But Don’t Brush Too Soon After Acidic Foods and Drinks

When you eat or drink something acidic, your enamel is more vulnerable to damage immediately afterward because acids remove minerals from tooth enamel. If you brush right away, even soft bristles can be abrasive. Wait about 60 minutes to brush, which gives your tooth surface time to get strong again with the enamel-building minerals found in saliva. 

  • Make Water Part of Your Healthy Diet

Easy, available, inexpensive—what’s not to like about water? Oh, and it’s also healthy for your teeth! Rinsing with water after a treat helps remove lingering food particles and acids. And drinking water when you’re thirsty helps you produce saliva. Saliva not only rinses our teeth, it helps neutralize acids and helps replace calcium and phosphate minerals which may have been stripped away by acids.

This July 21st, we’re not really celebrating junk food—we’re celebrating all the things you do to protect your oral health. So, whether you’re indulging today or not, keep your teeth their healthiest by making junk food a rare treat, keeping up with your daily brushing and flossing, and seeing your dentist regularly for checkups and cleanings. Let’s make National Junk Food Day just another day in a year filled with healthy smiles!

Celebrate the Fourth with a Smile!

July 2nd, 2025

As our nation prepares to observe its birthday, we’d like to share some timely dental tips to help make celebrating the Fourth of July more enjoyable for you and healthier for your teeth and gums.

Hydrate

It might be hot and humid where you’re living, so be sure to keep hydrated in the backyard or along the parade route. Proper hydration is essential for both your overall health and your oral health. Drinking water helps prevent cavities by washing away food particles and bacteria and reducing acidic conditions in the mouth. 

Use Ice for Cooling, not Chewing

If you’re enjoying an icy cold beverage to beat the heat, don’t crunch down on that ice! Chewing on ice can lead to immediate disaster in the form of a chipped or cracked tooth or a broken filling or crown. And, over time, munching ice will damage your enamel, making your teeth more sensitive to heat and cold and more vulnerable to cavities. 

Enjoy All Your Cookout Favorites

If you celebrate the Fourth with family and friends, there’s a good chance you’re celebrating outdoors. According to surveys, Independence Day is the most popular grilling day in the country. Are you sitting on the picnic table sidelines because of loose teeth, tooth pain, or missing teeth? Don’t miss out on any of the fun in Mill Creek! 

  • Tooth pain can be caused by cavities. It can also be a sign of a damaged tooth or an infection. If you suffer persistent tooth pain lasting several days or more, it’s time for a dental appointment.
  • Gum disease can cause bone loss, loose teeth, and lost teeth, making sharing a meal with friends something you avoid instead of something you look forward to. Regular flossing, cleanings, and checkups will help keep your gums in the pink. If you have advanced gum disease, we can discuss treatment options.
  • If you or a loved one wear braces, be sure your BBQ choices are not only delicious, but safe for wires and brackets. Offer menu options which are braces-friendly—that is, which are soft and easy to eat rather than hard, crunchy, or sticky. Remove kernels from corn on the cob and have utensils available to cut finger foods like burgers and hot dogs into fork-friendly bits. 
  • Missing teeth not only make dining difficult, but can also lead to gum disease, decay, and misalignment in adjacent teeth. To enable you to enjoy your meals and to protect your dental health, talk to Dr. Kerry Olszewski about implants, bridges, or dentures to make your smile complete again.

Whether you’re marching in the parade, enjoying a meal with family and friends, oohing and aahing at the fireworks, or all of the above, we wish you a healthy and happy Fourth of July! If you have any dental concerns, we’re here at Mill Creek General Dentistry to help you achieve your best smile every day of the year.

Good Dental Hygiene Impacts Overall General Health

July 2nd, 2025

There are many ways in which your oral health has an impact on your overall general health. There are naturally occurring bacteria in the mouth. Some of those bacteria, including strep and staph, are harmful, while other bacteria are essential for the balance of intestinal flora. The healthier your mouth is, the less likely it is the harmful bacteria will travel to other parts of your body to infect it and make you sick. There is much more to good dental hygiene than brushing and flossing.

Historical Methods of Maintaining Oral Health

Ancient civilizations relied on natural remedies for maintaining oral health. Around 250 AD, the Kemetic Egyptians used myrrh and other herbs as antiseptics for treating infected gums. Two centuries later, the Nubians, who lived in the Nile River valley, drank beer to ease the pain of infected teeth. That probably sounds crazy, but their beer was effective because they used grains that were contaminated with the same bacteria that produce the antibiotic tetracycline.

Today's Biggest Dental Hygiene Challenge

In the past, tooth decay was more of an issue because there was no routine dental care, and problems that are routinely treated today went untreated. Thanks to fluoridated water, and toothpastes containing fluoride, tooth decay is far less problematic than it was a century or more ago. Gum disease has replaced tooth decay as the most serious dental problem facing people today. According to the American Dental Association, a staggering 80 percent of Americans over age 65 suffer from some form of periodontal disease.

Ironically, if that infection attacked any other part of your body, especially in a place where it was clearly visible, you would head to your doctor for treatment immediately. People tend to ignore gum tenderness and bleeding. When the tenderness and bleeding aren't treated, the inflammation can turn into periodontitis. The longer you allow the inflammation to go untreated, the greater the likelihood that it will affect other body parts. Make sure to visit Dr. Kerry Olszewski at Mill Creek General Dentistry regularly to be proactive about dental health!

Researchers are now discovering that untreated inflammation in the mouth acts as a driving force for multiple chronic illnesses, including clogged arteries, heart attacks, arthritis, and even cancer. That inflammation is one of many hypotheses that may explain how chronic infections can trigger systemic diseases, and even intensify existing ones. Bacterial overgrowth in the inflamed gum tissue can enter the bloodstream through the food you eat, and from daily brushing.

Caring for your mouth at home is just as important as visiting our office for exams!
