What is a cavity?

December 10th, 2025

Cavities are the reason why most people fear going to the dentist. But they’re also the reason you should be visiting Dr. Kerry Olszewski on a regular basis.

Specifically, cavities are the breakdown of teeth caused by acid from food, bacteria, and plaque that inhabit the inside of the mouth. While many people simply think that cavities only form on top of a tooth, Dr. Kerry Olszewski and our team at Mill Creek General Dentistry want you to know they can actually form on the sides along the gum line and between the teeth, too. This acid will eat away at the tooth, forming a soft hole.

Anybody, either children and adults, can get cavities. In fact, according to the Centers for Disease Control and Prevention, in the U.S. alone about 16 percent of all children ages six to 19 have untreated cavities, and about 24 percent of adults 20 to 64 years old have them. This is detrimental to overall oral health, because cavities have a tendency to grow over time, potentially spreading to other teeth and causing increased oral pain, possibly even affecting the nerve.

That's why it's important to ensure that you're visiting Mill Creek General Dentistry at least once every six months, so that cavities can be found and filled before they become too problematic and painful. Typically, they're found by doing a routine teeth cleaning, though X-rays or further examination may be necessary to determine the full extent of a cavity. Cavities are treated by removing the area of the tooth where decay has set in and rebuilding the tooth with a metal filling. If the cavity is too large, however, more extreme measures may be necessary, such as placing a crown or performing a root canal.

As we noted above, cavities are why people dread going to the dentist, but also the reason everyone should see the dentist every six months. Additionally, brushing twice daily, flossing, and cutting down on sugar-packed foods can reduce the risk of developing cavities.

How does a tooth decay?

December 3rd, 2025

When acids are allowed to erode tooth enamel long enough to leach calcium and other minerals from your enamel and dentin, a process called demineralization occurs. This rapidly leads to tooth decay unless reversed by good oral hygiene and professional dental cleanings at our Mill Creek office. Acids responsible for tooth decay come from the wastes of mutans streptococci and lactobacilli bacteria that thrive in dental plaque, a substance that is the leading cause of periodontitis.

Where do demineralizing acids come from?

Dietary sugars comprise the bulk of tooth-decaying acids, including table sugar, cooked starches, fructose, glucose, and lactose. In fact, as soon as you bite down on a sugary cookie or into a French fry, bacteria start digesting sugars, breaking them down and eventually excreting them as demineralizing acids. As this bacteria colony grows and becomes organized, plaque develops and forms that tough, yellowish coating you often see on the tops of teeth at the gumline.

Plaque is the Problem

Dental plaque is a filmy type of nesting place for bacteria that also keeps acids pressed against tooth enamel. Since plaque cannot be removed by brushing, it is important that a person who suffers tooth decay visit Mill Creek General Dentistry immediately so we can use special tools to scrape and thoroughly clean teeth.

Signs of Tooth Decay

Early tooth decay and cavities remain asymptomatic until demineralization creates a hole deep enough to reach the tooth’s inner tissues and nerve endings. Eventually, tooth decay will cause tooth sensitivity, toothache, vague pain when biting down on the affected tooth, and possibly pus seeping around a tooth’s gum line if the decay creates an infection. If treatment is delayed long enough, a decaying tooth may loosen, crumble, and ultimately fall out, which leaves an empty or partially empty socket.

Preventing Tooth Decay

Getting regular checkups with Dr. Kerry Olszewski, brushing and flossing twice a day, and eating fruits or crunchy vegetables at snack time instead of a candy bar or doughnut are the three best ways to keep your teeth healthy, white, and where they should be: in your mouth.

What's in toothpaste and how does it work?

December 3rd, 2025

Dr. Kerry Olszewski 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.

Holiday Gift Ideas for Healthy Holiday Smiles

December 3rd, 2025

Need some gift ideas for family members and friends who seem to have absolutely everything? Who are impossible to shop for? Who tell you not to worry, it’s the thought that counts? Well, we have a few suggestions which will show the people on your gift list that you’ve put a lot of thought into their gifts this holiday season. 

You love to see your friends and family smile, so we’ve come up with some smile-worthy ideas designed for their specific interests. 

Environmental Ally

The world is becoming a more eco-conscious place, and happily this transformation includes products designed for personal care. Put together a spa basket which is good for your friend’s comfort, dental health, and the planet!

A recycled gift box filled with environmentally friendly bath products and organic cotton face cloths becomes even more mindful with the addition of bamboo or recycled plastic toothbrushes, zero-waste fluoride toothpaste tablets, and biodegradable picks and floss. 

Don’t forget to include a colorful, insulated water bottle for sustainable hydration—and washing away food particles when there’s no handy place to brush after eating. Healthy planet/healthy smile.

Talented Techie

If your friend or relative is cutting edge high-tech, maybe it’s time for a dental upgrade. 

Modern electric toothbrushes offer plenty of options for the tech-savvy. They come with different settings for brushing and massaging. They can let brushers know if they’ve brushed long enough, if they’re brushing too hard, or when the brush head needs to be retired. Smart models even link to apps, which can, among other things, map out any missed spots in brushing coverage or suggest more effective brushing angles. 

And for an extra thoughtful touch, include a packet of plaque disclosing tablets. Chew one of these helpful little tablets and they will reveal any plaque that’s still on the teeth.

Adventure Seeker

How about a new backpack or carry-all for outdoor or travel adventures? A travel first aid kit is always a welcome addition for the person on the go.

Go the extra step and help a friend be prepared for anything with an emergency dental kit. You can find these lightweight kits in stores or online, or you can assemble one yourself with a travel-size toothbrush and toothpaste, floss, a travel mirror, cotton rolls, pain relievers, and even temporary fillings. Include a pack of sugar-free gum—it helps with altitude changes and hydration. Ask Dr. Kerry Olszewski or the team at Mill Creek General Dentistry for suggestions!

Timeless Trendsetter

Older relatives might love a selection of modern gifts designed with old-fashioned comfort in mind, such as an automatic jar opener and a selection of jams, trekking poles for easier hiking, or wireless earbuds for enjoying music or an audio book.

For a lifetime of healthy smiles, consider adding a water flosser to your gift basket. Gum disease is a leading cause of tooth loss for older Americans. Water flossers are a great way to eliminate stubborn plaque, especially when mobility issues make manual flossing difficult. Adjustable water pressure applies just the right amount of cleaning power, and the flow can be directed to the gumline, between teeth, or anywhere necessary. 

Film Buff

If your bestie likes nothing better than an evening spent in front of the home screen, consider a subscription or gift card for a streaming service tailored to his or her favorites, whether it’s classic films, sci-fi, action, rom-coms, or epic adventures. 

And don’t forget the binge-watch treats! Fill a basket with dental-friendly goodies like fresh fruits, nuts, and dark chocolate. Include a collection of simple sparkling waters or a gift card for vitamin-rich smoothies. Who needs sugary candies and sodas with options like these?

No matter who’s on your shopping list, tailoring your gifts to their interests and their well-being is a great way to share happy, healthy holiday smiles with family and friends in Mill Creek.
