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!

Is There an Act Three for Our Teeth?

November 19th, 2025

Act One: Those 20 adorable baby teeth which begin arriving when you’re about six months old and are probably gone by the time you’re twelve.

Act Two: The 32 (if you have all your wisdom teeth!) adult teeth which start showing up around the age of six, and need to last the rest of your lifetime. Unless there’s an . . .

Act Three: Where science has discovered a way to repair damaged teeth or create replacements for lost teeth that would look and function just like our original teeth.

Sounds like science fiction, doesn’t it?

In biological terms, of course, we’re not there yet. But teams of scientists around the world have been working toward just this goal—the ability to repair a tooth with its own biological material or even grow a new tooth when an adult tooth is seriously damaged or lost.

Because the pulp—the living tissue inside each tooth—contains dental stem cells, some researchers are studying whether these cells can be used to regenerate the living pulp inside a damaged tooth. Even more exciting, there’s research being done into the possibility of using these stem cells to rebuild an entire tooth—pulp, dentin, and hard enamel exterior. Because the supply of usable dental stem calls is quite small, and process of guiding these cells to create all the varied parts of the tooth is quite complex, this research is in its early stages.

In other studies, scientists have focused on tooth regeneration by studying the teeth of other species. Mice, for example, have front teeth with open roots. This allows these teeth to keep growing up as they wear down, because stem cells inside mouse gums are always working to create new tissue. Even though our teeth are not exactly comparable (no open roots in human teeth!), finding out just how this tissue regeneration works in mice and other animals might help find an answer for human tooth regeneration.

Right now, these scientific goals are just that—goals for a future day. But in the meantime, your quality of life doesn’t need to suffer when you lose an adult tooth. You can enjoy a third act right now with dental implants.

Cosmetic concerns aren’t the only reasons why you want your complete smile restored in the event of a lost tooth. A missing tooth can lead to many unpleasant consequences:

  • Speaking and eating can become more difficult.
  • Lack of stimulation from biting and chewing can cause the bone beneath the lost tooth to shrink.
  • Other teeth can shift to fill the gap left behind, which can affect tooth, bite, and jaw alignment.
  • Loss of teeth can lead to loss of confidence.

Unlike dentures or bridges, dental implants are designed to function just like your natural teeth.

The post, or base, of each implant fuses with the bone in your jaw, acting as a “root” for the implant. Once the post has fused with the bone around it, a crown designed to match your other teeth in shape and color is secured to the post. You can eat, speak, brush, floss, keep your bone healthy, and smile confidently just as you did before.

Will biological replacements be ready for your third act in the near future? Probably not. But that’s not to say this will never be possible! In the meantime, take care of your teeth with daily brushing and flossing, eat a dental-healthy diet, and visiting our Marysville, WA office as recommended.

You do your best to keep your teeth intact and in place—but if you lose one through trauma or decay, talk to Dr. Kelly Peterson about an implant. Because in any stage of life, the most important result is the happy ending a healthy and confident smile brings you!

Five Reasons for Your Bad Breath

November 12th, 2025

Bad breath, or halitosis, is probably not a matter of life or death. But it can make you feel self-conscious and have a negative impact on your life. The majority of people suffering from bad breath are dealing with oral bacterial. However, there are other causes of this embarrassing problem. Learning more can help you fight this solvable problem.

Five Causes of Embarrassingly Bad Breath

  1. Dry Mouth. A decrease in saliva flow can be caused by several things. Most often, medication or mouth breathing are the culprits. As saliva helps wash away food particles from your mouth, it prevents bad breath. Dry mouth can be dealt with by stimulating salivation.
  2. Gum Disease and Poor Oral Hygiene. Not brushing and flossing well enough or with enough frequency can lead to gum disease, which leads to bad breath. Halitosis can be a sign that plaque is present on your teeth.
  3. Food-Related Bad Breath. Food particles that aren't brushed or flossed away attract bacteria that leads to bad breath. It's especially important to brush after eating strong-smelling foods, such as garlic or onions.
  4. Smoking and Tobacco. Tobacco is bad for your health, and that includes your oral health. Smoking or chewing tobacco can contribute toward the development of gum disease, as well as oral cancer.
  5. Mouth Infections and Other Medical Problems. A mouth infection, sinus infection or even the common cold can cause you to temporarily have bad breath. Even conditions such as diabetes and reflux can cause halitosis. It's always wise to see Dr. Kelly Peterson to help determine the cause.
