Canker sores, cold sores, and mouth sores: What's the difference?

March 12th, 2025

At Mill Creek General Dentistry, we know many people have experienced some form of mouth sores or irritation. Some mouth sores are harmless and go away on their own after a few days, while others are more serious and should not be ignored. Mouth sores occur for many different reasons, but bacterial infections, viruses, or funguses often trigger them. The best way to tell the difference between a canker sore and a cold sore is that canker sores occur inside the mouth while cold sores occur on the outside the mouth.

The most common mouth sores are:

Canker sores: A non-contagious, small, grayish ulcer with a red border, canker sores appear inside the mouth. While outside factors such as stress, fatigue, or allergies may increase the chances of developing a canker sore, most health experts believe they stem from bacteria or a virus that attacks the immune system. Canker sores typically heal within a week or two.

Cold sores: Also called fever blisters, cold sores are contagious groups of fluid-filled blisters that often erupt around the lips and sometimes under the nose or around the chin. Cold sores are the result of the herpes simplex virus, and once infected, the virus remains in the person’s blood stream.

Leukoplakia: A potential warning sign of oral cancer, leukoplakia is a premalignant lesion that appears as a white patch on the inside of the mouth, tongue, or gums. The lesions, which are caused by excessive cell growth, usually afflict those who smoke tobacco. Dr. Kerry Olszewski may choose to have the lesion biopsied if the outbreak appears severe.

Oral candidiasis: Also called oral thrush or moniliasis, this condition is caused by the overgrowth of a type of yeast called candida. Common symptoms of oral candidiasis include white spots inside the mouth and on the tongue, redness or discomfort in the mouth area, sore throat,difficulty swallowing, and cracking at the corners of the mouth. It is important to visit Dr. Kerry Olszewski if you have oral candidiasis. If left untreated, it may infect your bloodstream, which can be very dangerous. Healthy adults do not usually get thrush, and the condition is most often seen in infants, the elderly, patients undergoing chemotherapy, or people with AIDS or other diseases that are known to weaken the immune system.

Should you have a mouth sore that lasts a week or longer, we encourage you to give us a call and schedule an examination at our Mill Creek office.

Detergent Foods: Clean your teeth while you eat!

March 12th, 2025

Did you know that there are certain foods you can eat which help to clean your teeth? We call them "detergent foods." In dentistry we look at the impact of food in three ways: the kind of food, how often it is eaten, and when it is eaten. Detergent foods should be the last piece of food you consume during a meal for best results. Think of them as the closest you can get to brushing your teeth.

A healthy diet is important for oral health as well as overall health, but here are some particular foods that can help clean your teeth and mouth:

  • Carrots
  • Apples
  • Celery sticks
  • Popcorn
  • Cucumbers
  • Pears
  • Lettuce
  • Cheese

As you can see, detergent foods are usually foods that are firm and crisp. They act like scrubbers on and around your teeth and gums and bring your mouth's pH back to 7.0, which is optimal.

Which foods are the worst for your teeth?

Cookies, cakes, breads, chips, crackers, soft drinks, dried fruit, and candies (what many people’s diets are full of) provide carbohydrates (sugar) to the bacteria in your mouth causing an acidic environment and increasing the chance of cavities and decay. These foods are sticky and don't rinse easily from your mouth. Avoid letting these foods sit on your teeth after eating them.

It also depends on how often you consume these foods throughout the day. For example, if you drink soft drinks, it's best to have it all in one sitting instead of sipping it all throughout the day. Doing so causes the perfect environment in your mouth for bacteria to flourish and your saliva never gets the chance to neutralize its pH.

This is where detergent foods can come into play. When you're about to finish your meal, have an apple, celery stick, or carrot. It will act like a "natural toothbrush." Also, try to make these detergent foods the basis for snacks you have throughout the day.

Always remember, these foods are not a replacement for brushing and flossing. You still need good dental hygiene regardless of what you're eating! For more tips and tricks for ideal oral health, ask Dr. Kerry Olszewski the next time you visit our Mill Creek office!

Planning Your Vegetarian Diet with Your Oral Health in Mind

March 12th, 2025

If you’ve been following a vegetarian or vegan diet, you know that there’s much more to living a healthy life than simply avoiding meat products. Making sure your diet includes enough protein, as well as any nutrients that are primarily available in animal products, takes planning, and there’s no one-menu-fits-all solution.

Why? Because there’s no one menu that will suit all vegetarians. Specific vegetarian diets can allow for many different options:

  • Vegan—a plant-based diet which excludes meat, fish, dairy, and egg products
  • Ovo-vegetarian—includes eggs as a dietary option, but no dairy
  • Lacto-vegetarian— includes dairy as a dietary option, but no eggs
  • Lacto-ovo-vegetarian—a meat-free diet which allows both dairy products and eggs

If you are a pescatarian, who eats fish on occasion, or a flexitarian, who sometimes includes meat in a meal, your menu options are even broader.

So let’s look at the big picture—a healthy vegetarian diet is really more concerned with the foods you do eat for nutrition rather than the foods you don’t. You can create a meal plan rich in all your essential nutrients with a little research, no matter which type of vegetarian diet is your go-to choice.

And while you’re constructing your ideal menu guidelines, don’t forget about your dental nutrition!

In terms of keeping your teeth and gums their healthiest, what important vitamins and minerals are often missing from vegetarian and vegan diets? Let’s look at three of them.

  • Calcium

Calcium is essential for maintaining strong bones and tooth enamel. Without enough calcium, a weakened jawbone leads to loose, and even lost, teeth. The acids in our food and the acids created by oral bacteria also weaken the minerals in enamel, including calcium. These weak spots can eventually become cavities. A diet rich in calcium not only supports the bones holding our teeth, but can even help repair, or remineralize, enamel which has been weakened by acidic erosion.

For vegetarians who include dairy in their diets, dairy products are a great way to include calcium. Milk, cheese, and yogurt are traditional and rich sources of this mineral.

For vegans, it’s a bit more challenging, but still doable! Non-dairy foods providing calcium include dark green vegetables (kale, broccoli, spinach), certain types of tofu, and fortified cereals, juices, and non-dairy milks.

  • Vitamin D

Now you’re ready to put that calcium to work by making sure you have enough vitamin D in your diet. Vitamin D not only helps keep our bones healthy, it also enables our bodies to absorb calcium. Bonus—it’s been linked to better gum health in several studies.

So how to get more vitamin D? If you eat dairy, most dairy products have been fortified with vitamin D. If eggs are a part of your diet, egg yolks are a great source. Pescatarians can enjoy the benefits of vitamin D from fatty fish such as tuna and salmon.

Because we get most of our vitamin D from sun exposure or foods derived from animals, plant-based foods are not a practical way to obtain the vitamin D you need. But, just as non-vegetarians can get plentiful vitamin D from fortified dairy products, vegans also have options. Try adding cereals, juices, and non-dairy milks fortified with this essential nutrient to your diet, or take a vegan vitamin D supplement.

  • Vitamin B12

Vitamin B12 is essential for healthy red blood cells, nerve cell development, brain function, and DNA production. (This is why it’s especially important for pregnant and nursing women.) Vitamin B12 can also impact your oral health. A B12 deficiency can cause a swollen, sore, or inflamed tongue, loss of taste, and gum, tongue, and mouth ulcers.

Unfortunately, vitamin B12 is reliably found only in animal foods and nutritional yeasts. If you would prefer an egg-free and dairy-free diet, look to B12 supplements or B12-fortified cereals, plant-based milks, energy bars, and other vegan options. This is a good subject to discuss with your physician, because even supplements and fortified foods might not provide enough B12.

In fact, Dr. Kerry Olszewski can be vital resources when you’re planning your healthiest vegetarian diet. The next time you visit our Mill Creek office, ask for recommendations for supplements if you’re concerned that diet alone can’t provide for all of your nutrition essentials. Finally, care should be taken to ensure that, even with supplements, you get the proper amount of the vitamins and minerals you need.

As a vegetarian, you are used to the concept of care. Whether it was concern for nutrition, the planet, the animal world, or another reason that drew you to a vegetarian diet, be sure to care for your body as well as your dietary choices. Careful planning can ensure a diet which supports not only your general health, but your oral health, for a lifetime of nourishing—and well-nourished—smiles.

Sleep Apnea: What a Dentist Can Do

March 5th, 2025

You find yourself drowsy and irritable all day. Or you have trouble sleeping, and when you do, you snore loudly throughout the night punctuated with silent pauses where you aren’t breathing at all. Or your loved ones tell you that you’ve been keeping them awake with your snoring or frightening them awake when you gasp for breath. Whatever symptom may have brought you to the doctor, you’ve been diagnosed with obstructive sleep apnea, and now it’s time to get this sleep disorder under control.

Obstructive sleep apnea occurs when the tissue in the back of the throat relaxes, partially blocking the airway, or structural problems in the mouth and throat (such as enlarged tonsils or tongue) obstruct air flow. The tissue around the air passage vibrates with every breath causing those annoying snoring sounds. More dangerous, an obstructed airway means that there is not enough oxygen getting into the lungs. The struggle to breathe wakes us, interrupting the deep sleep we need to function. Untreated, the results of sleep apnea can range from drowsiness and irritability to a greater risk of high blood pressure, heart disease, and stroke. Luckily, there are several approaches to combatting this form of sleep apnea, including life style changes, surgery or breathing machines, and orthodontic appliances.

  • Lifestyle Changes

Sleep apnea is more likely to affect those who are overweight, smoke, use alcohol, take certain medications, or sleep on their backs. If you can make changes in your lifestyle that will restore the quality of your sleep, this is a great first option.

  • Surgery or Breathing Machines

Sometimes obstruction of the airway is caused by structural problems in the throat or mouth. Tissue can be reshaped or removed during surgery to widen and stabilize the breathing passage. Or you might be prescribed a machine such as a CPAP (continuous positive airway pressure) machine, which blows pressurized air through a tube and mask to keep the airway open during sleep.

  • Oral Appliances

Dr. Kerry Olszewski can also be an important resource if you struggle with obstructive sleep apnea. Many people suffering from this disorder prefer an oral appliance for its effectiveness, comfort, and convenience. One common oral sleep appliance is designed to support your lower jaw in a forward position. This jaw movement increases the open space of your airway as you sleep. Other appliances can prevent the tongue from blocking the airway and obstructing air flow. These appliances resemble mouthguards and retainers, and, like them, are custom made just for you. We will recommend the type of appliance best suited to your needs, and will take a model of your mouth and teeth so that a lab can craft an appliance that will be a perfect fit. We will adjust it for comfort if necessary, instruct you on its use and care, and schedule follow up treatment to make sure the appliance is treating your sleep apnea as efficiently as possible.

Whether you opt for a change of lifestyle habits, a CPAP machine, surgery, or an oral appliance, it is important that you treat this sleeping disorder. Left untreated, obstructive sleep apnea can have many serious consequences. If you suspect you might have sleep apnea, talk to us during your next visit at our Mill Creek office. You deserve a good—and healthy—night’s sleep.
