A Spot of Trouble?

December 17th, 2025

Your smile is in the spotlight every day, helping you greet the world with confidence! But when you’re self-conscious about discolored spots on your teeth, it’s time to get some professional advice to deal with these troublesome tints.

Discolored patches, both dark and light, can develop for a number of different reasons. Some markings are cosmetic only, and some spots require treatment. Some can be removed with a professional cleaning, and some might require more serious restoration. Let’s have a look at some of the common causes of enamel discoloration.

  • Cavities

Decayed enamel can appear as a brown spot on the tooth. A dark edge around a filling might mean decay underneath.

Regular checkups at our Marysville, WA office will help catch small cavities before they become big ones. If you need a filling, the filling color can be matched to your tooth color for an undetectable restoration.

  • Demineralization

Bacteria in plaque produce acids, which attack our teeth. These acids erode minerals such as calcium and phosphorus from enamel, leaving a weak spot that is vulnerable to decay. This process is called “demineralization,” and often leaves a whiter spot on a tooth where minerals have leached away. Common reasons for demineralization are neglecting dental hygiene, failure to clean around braces, and a diet filled with sugary and acidic foods.

Fluoride and enamel-strengthening toothpastes, a healthy saliva flow, and a balanced diet help our teeth “remineralize,” bathing teeth in minerals that can help replace those that have been lost. But if you have lingering white spots due to demineralization, Dr. Kelly Peterson can provide some options, including whitening, microabrasion, and veneers.

  • Fluorosis

Fluorosis is a cosmetic condition caused by exposure to too much fluoride while the permanent teeth are still forming (generally, during the years before a child’s eighth birthday). Small white spots and patches are a common result of mild fluorosis. In more serious cases, teeth can be pitted and stained with brown, gray, or black spots.

Preventing fluorosis begins in early childhood. Talk to Dr. Kelly Peterson about fluoride levels in local tap water if you have any concerns. Use only the recommended amount of toothpaste (the size of a grain of rice for children three and under; the size of a pea for children three to six), and show your child how to spit out toothpaste and rinse after brushing. Keep fluoride toothpastes and other fluoride products out of the reach of young children. Don’t give children fluoride supplements or fluoride rinses without discussing it with Dr. Kelly Peterson.

If your own teeth have been affected by fluorosis, talk to us. Again, this is a cosmetic condition affecting otherwise healthy teeth. Whitening treatments can be helpful in mild cases, microabrasion has been effective for mild to moderate cases, and, for severe cases, cosmetic restorations such as bonding and veneers are an option.

  • Tartar

Are you seeing an accumulation of dark brown spots and stains on your teeth, especially between the teeth and at the gum line? This might mean that you have tartar buildup. When you brush plaque away every day, your enamel stays smooth and clear. But when plaque builds up over time, it hardens and becomes tartar.

How hard is tartar? So hard that it can only be removed with a professional cleaning. Eliminate this source of spots and staining with twice daily brushing and daily flossing, and make sure regular professional cleanings are on your calendar.

  • Other Causes

Medications taken while teeth were developing (notably, antibiotics in the tetracycline family) can cause discoloration. Medical conditions such as celiac disease and enamel hypoplasia can affect both tooth color and enamel formation.

Cosmetic treatment and restorations can help with discoloration caused by medications, and restorations such as bonding, veneers, and crowns can restore tooth appearance and function when medical conditions cause imperfections in enamel color and structure.

If you’re unhappy with the overall whiteness of your smile, a professional whitening might be just what you’re looking for. If specific patches, streaks, and spots of a different color are dimming your bright smile, it’s time for an exam. Dr. Kelly Peterson will be able to tell you the reason for any discolored enamel as well as present you with all your treatment options. Put the spotlight back where it belongs—on your healthy, confidant smile!

Forget Something? It’s on the Tip of Your Tongue!

December 10th, 2025

Let’s see…

Toothbrush? Check.

Fluoride toothpaste? Check.

Floss? Check.

Two minutes of thorough brushing? Check.

Careful cleaning around your brackets and wires? Check.

Wait… there’s something else… it’s right on the tip of your…

Ah! Your tongue! Whenever you brush, morning, evening, or any time in between, if you want the freshest breath and cleanest teeth, don’t forget your tongue.

Why your tongue? Because the tongue is one of the most common sources of bad breath. Let’s examine just why this occurs.

The tongue is made up of a group of muscles that help us speak and chew and swallow. But there’s more to this remarkable organ than mere muscle. The surface of the tongue is covered with mucous membrane, like the smooth tissue which lines our mouths. But the tongue isn’t completely smooth—it’s textured with thousands of tiny bumps called papillae.

These little elevated surfaces have several shapes and functions. Some make the tongue’s surface a bit rough, which helps move food through your mouth. Some are temperature sensitive, letting you know that your slice of pizza is much too hot. And some are covered with thousands of the taste buds, which make eating that pizza so enjoyable.

All of these papillae with their various functions combine to create a textured surface, filled with miniscule nooks and crannies. And if there’s a nook or a cranny where bacteria can collect, no matter how miniscule, it’s a good bet that they will, and the surface of the tongue is no exception. But bacteria aren’t alone—the tongue’s surface can also hide food particles and dead cells.

How does this unappealing accumulation affect you? These elements work together to cause bad breath, especially the bacteria that break down food particles and cell debris to produce volatile sulfur compounds—compounds which create a particularly unpleasant odor. Including your tongue in your brushing routine helps remove one of the main causes of bad breath.

And that’s not the only benefit! Cleaning the tongue helps eliminate the white coating caused by bacterial film, and might even improve the sense of taste. Most important, studies show that regular cleaning noticeably lowers the levels of decay-causing plaque throughout the mouth.

So, how to get rid of that unwanted, unpleasant, and unhealthy debris?

  • When you’re done brushing your teeth, use your toothbrush to brush your tongue.

Clean your tongue by brushing gently front to back and then side to side. Rinse your mouth when you’re through. Simple as that! And just like a soft-bristled toothbrush helps protect tooth enamel and gum tissue, we also recommend soft bristles when you brush your tongue. Firm bristles can be too hard on tongue tissue.

  • Use a tongue scraper.

Some people find tongue scrapers more effective than brushing. Available in different shapes and materials, these tools are used to gently scrape the surface of the tongue clean of bacteria and debris. Always apply this tool from back to front, and rinse the scraper clean after every stroke. Wash and dry it when you’re through.

  • Add a mouthwash or rinse.

As part of your oral hygiene routine, antibacterial mouthwashes and rinses can assist in preventing bad breath. Ask Dr. Kelly Peterson for a recommendation.

  • Don’t brush or scrape too vigorously.

Your tongue is a sturdy, hard-working organ, but tongue tissue is still delicate enough to be injured with over-vigorous cleaning.

Taking a few extra seconds to clean your tongue helps eliminate the bacteria and food particles which contribute to bad breath and plaque formation. Make this practice part of your daily brushing routine—it’s a healthy habit well worth remembering!

Diet and Dental Health: What to eat and what to avoid

December 3rd, 2025

You are probably aware that guzzling soda and drinking those sugary Starbucks Frappuccinos aren’t particularly good for your dental health. But how much thought do you give to the effects of your diet on your teeth? Practicing healthy eating habits isn’t just helpful for your waistline, it also ensures that your teeth stay strong and cavity-free.

How diet affects dental health

Our team at Northwest Smile Design will tell you that your mouth is a complicated place on a microbiological level. Harmful bacteria form dental plaques which convert the sugars in food to acids that wear away at tooth enamel. Meanwhile, saliva washes away some of the detrimental acids, while minerals work to rebuild where teeth are damaged. The foods you eat are important for managing this balancing act between harmful bacteria and helpful rebuilding agents.

Rethinking your diet to prevent cavities

Carefully considering your dietary choices is a smart way to become mindful of the foods you eat and how they affect oral health.

Foods to eat

  • Calcium- and phosphorus-rich foods. We’ve all heard that milk builds strong bones, and your teeth are included in that. Milk, cheese, nuts, and chicken are strong sources of calcium and phosphorus. These minerals are used to repair damage to the teeth’s enamel.
  • Crunchy fruits and vegetables. Biting into an apple stimulates saliva flow, which washes harmful acids from the surface of your teeth. Turn to other crunchy fruits and vegetables, including carrots, celery, pears, and lettuce, to increase saliva production.
  • Sugar substitutes. If you have a sweet tooth but want to decrease tooth decay, sugar substitutes such as Stevia or Equal provide a sugary kick without harming your teeth.

Foods to avoid

  • Sugary snacks. Cookies, cakes, candies, and other sugary treats provide a feast for the acid-producing bacteria in your mouth. Furthermore, these foods often get stuck in the ridges of your teeth, and provide a breeding ground for new bacteria.
  • Acidic fruits and vegetables. Foods high in acidity, such as tomatoes, citrus fruits, berries, peaches, and lemons, wear away the enamel of your teeth. Because these foods can be part of a healthy diet, remember to brush after eating them or swish with a mouth rinse to protect your teeth.

Eating well is an essential part of keeping your teeth healthy. Consult Dr. Kelly Peterson about your diet for tips on food habits that keep your teeth strong and cavity-free.

Thanksgiving in North America

November 26th, 2025

Thanksgiving marks the start to the holidays; a season filled with feasting, indulging, and spending time with family and friends are always special. Thanksgiving is a holiday meant for giving thanks, and while this may seem like such a natural celebration, the United States is only one of a handful of countries to officially celebrate with a holiday.

Unlike many holidays, Thanksgiving is a secular holiday, and it is celebrated on the fourth Thursday in November in the United States. In Canada, it is celebrated on the second Monday of October, which is, oddly enough, much closer to a time when harvests were likely gathered. In addition to the different dates, the origins of the celebration also share different roots.

Thanksgiving in the United States

Giving thanks for a bountiful harvest are not new, but the modern day holiday in the US can be traced to a celebration at Plymouth in Massachusetts in 1621. This feast of thanksgiving was inspired by a good harvest, and the tradition was simply continued on. At first, the colony at Plymouth didn't have enough food to feed everyone present, but the Native Americans helped by providing seeds and teaching them how to fish, and they soon began to be able to hold a feast worthy of the name. The tradition spread, and by the 1660s, most of New England was hosting a Thanksgiving feast in honor of the harvest.

Canadian Thanksgiving

An explorer of early Canada named Martin Frobisher is accredited for the first Canadian Thanksgiving. He survived the arduous journey from England through harsh weather conditions and rough terrain, and after his last voyage from Europe to present-day Nunavut, he held a formal ceremony to give thanks for his survival and good fortune. As time passed and more settlers arrived, a feast was added to what quickly became a yearly tradition. Another explorer, Samuel de Champlain, is linked to the first actual Thanksgiving celebration in honor of a successful harvest; settlers who arrived with him in New France celebrated the harvest with a bountiful feast.

A Modern Thanksgiving

Today, Thanksgiving is traditionally celebrated with the best of Americana. From feasts and football games to getting ready for the start of the Christmas shopping season, Thanksgiving means roasted turkey, pumpkin pie, and green bean casserole. No matter how you celebrate this momentous day, pause for a moment to give thanks for your friends, family, and all the bounties you’ve received. Happy Thanksgiving from Northwest Smile Design!
