What is a palatal expander?

November 12th, 2025

Orthodontists like Dr. Andrew Nalin recommend a first orthodontic visit and evaluation for your child around the age of seven. We will evaluate your child’s jaw and facial development and make sure that there is enough room in the mouth for the permanent teeth when they arrive. One of the recommendations we might make for early treatment is the use of a palatal expander. If you are unfamiliar with this device, let’s take a closer look at why it’s necessary and what exactly it does.

Why do we recommend the palatal expander?

There are two dental arches, composed of the upper and the lower teeth, in your child’s mouth. This arch-shaped design is meant to accommodate all the permanent teeth. Further, when the upper and lower teeth meet, they should result in a healthy occlusion, or bite.

Sometimes, the upper dental arch is simply too small to accommodate all of your child’s permanent teeth, leading to crowding, extractions, and impacted teeth. Also, a too-narrow arch can result in a crossbite, where some of the upper teeth bite inside the lower ones. An improper bite can lead to problems such as TMJ (temporomandibular joint) disorder, improper wear and stress on teeth, certain speech difficulties, and other potential complications. The palatal expander was designed to prevent these problems from occurring.

What is a palatal expander and how does it work?

The expander itself is a device that increases the size of the upper dental arch. Before your child’s bones are finished growing, the space between the two bones of the upper palate is filled with cartilage. This tissue is flexible when children are young, but gradually fuses solidly into place by the time they are finished growing (usually in the early to mid-teens). If the arch can be widened to accommodate the emerging permanent teeth, or to reduce malocclusions, this improvement can also affect the need for, and length of, future dental work.

There are several types of expanders available at our Mount Vernon, WA office. These are custom-made appliances, commonly attached between the upper teeth on each side of the jaw. The two halves of the device are connected with a screw-type mechanism that can be adjusted to widen the upper palate and dental arch with gentle pressure. This is a gradual process, with small adjustments usually made once or twice a day to slowly move the bones further apart. As weeks go by, you will notice a successful change in the spacing of the teeth. Your child might even develop a gap in the front teeth, which is normal and will generally close on its own.

If you would like more detailed information, talk to Dr. Andrew Nalin about the palate expander. We can tell you what to expect from this treatment if we think it is best for your child’s unique needs, and how to make it as easy as possible for your child. Our goal is to provide your child with the healthiest teeth and bite possible, always making use of treatments that are both gentle and effective.

Tips for Cold and Flu Season

November 5th, 2025

It’s peak cold and flu season, a time to be especially conscious about your health. We have some suggestions to help you navigate this contagious time of year, with bonus tips for a healthy smile.

  • Wash Up! 

Bacteria and viruses can live for hours and even days on non-porous surfaces like doorknobs, phones, and keyboards. That’s why it’s so important to wash your hands before touching your mouth, nose, and eyes, before brushing and flossing, and before you cook or eat. Washing with plain soap and water will eliminate most germs.

Bonus Tip: Keeping your fingers away from your mouth does more than prevent the transmission of bacteria and viruses. Fingernail biting can damage brackets, wires, and even tooth enamel. Prolonged thumb or finger sucking can affect tooth and jaw alignment. Delicate gum tissue can be injured or infected by broken or dirty nails. If you’d like to break harmful oral habits, talk to Dr. Andrew Nalin for suggestions.

  • Stay Hydrated

Hydration supports healthy skin, helps regulate blood pressure and body temperature, and is vital for digestion and other bodily functions. Proper hydration is also important for a healthy immune system and healthy mucous membranes, which will help you fight off colds and flu. Talk to your doctor about your ideal amount of daily hydration, whether from water, other fluids, or water-rich foods.

Bonus Tip: We also need to be hydrated to produce healthy levels of saliva. Saliva washes away food particles and bacteria from teeth and braces and helps neutralize enamel-eroding acidity in the mouth.

  • Eat Healthy Foods

A healthy diet is crucial for a healthy immune system, with foods such as lean proteins, fruits, vegetables, whole grains, and low-fat dairy products.

Bonus Tip: A balanced diet is good for your oral health, too! We need vitamins A and C for healthy gums and oral tissues, minerals like calcium and phosphorus to keep tooth enamel strong, and dairy products enriched with vitamin D, which enables our bodies to absorb the calcium we get in our diet.

What happens if you become ill despite your precautions? 

  • Reduce the Chance of Infecting Others

If you’re ill, you can help stop the spread of germs by limiting contact with other people, covering your mouth and nose when you cough or sneeze, washing your hands frequently, and cleaning the common surfaces in your house which harbor germs. 

Bonus Tip: Sharing isn’t caring when it comes to colds and flu. No matter how close you are to your family members or roommates, your toothbrushes shouldn’t be close at all. Let your brush air-dry in an upright position away from other brushes to avoid contamination. 

  • Be Choosy about OTC Medications 

If you take sugary cough or cold medications, brush or rinse afterward. Sugar-free cough drops are better for your teeth than sweet lozenges which bathe your enamel in sugar as you let them dissolve. 

Bonus Tip: Don’t bite into cough drops! You risk not only broken brackets and wires, but chipped and cracked teeth.

  • Keep Up with Healthy Habits

Be sure to keep hydrated, especially if you’ve been suffering from vomiting or diarrhea. Get the sleep you need to recover. Eat a well-balanced diet.

Bonus Tip: Stay on top of your dental hygiene and brush and floss as usual, with one caution. Vomiting brings up harsh stomach acids which weaken the mineral bonds keeping tooth enamel strong, so brushing right away can be abrasive. If you throw up, rinse your mouth with water and wait 30 minutes before brushing to allow your enamel to come back to full strength.

  • Stay Home When You’re Sick

You’ll get better faster with proper care, which includes getting the rest you need to recover. And you won’t be sharing germs with the people around you.

Bonus Tip: If you have an appointment scheduled with your orthodontist, reschedule if necessary. Your orthodontic team at Nalin Orthodontics will be happy to accommodate you to prevent the spread of germs and to make any procedure a more comfortable one.

It’s the height of cold and flu season in Mount Vernon, WA, but you’re not alone! Talk to your doctor about immunizations and other preventative measures. If you do become ill, follow your physician’s recommendations. And if you have any orthodontic concerns, your orthodontic team is prepared with timely advice—at any time of year.

Witch Halloween Treats Are Trickiest for Your Teeth and Braces?

October 29th, 2025

It’s that time of year again—Halloween! Carving pumpkins. Creating costumes. And, of course, collecting candy.

But some of the candies in that collection aren’t much of a treat for your teeth. When you’re deciding on the perfect pieces to choose from the candy cauldron, here are some tricks to identify the ones that can be more frightful than delightful for your tooth enamel and braces:   

  • Is It Chewy or Sticky?

Any sticky or chewy candy—caramels, taffy, licorice, gummy anythings—is candy that also sticks to your teeth. And it really sticks in between your teeth, where it’s harder to brush away.

The problem? Bacteria in plaque love sugar, and sticky candies provide them with hours of sugary feasting. Bacteria use this sugar to make acids, and acids cause weak spots in tooth enamel. These weak spots will get bigger over time as the bacteria keep on attacking your enamel, and that’s how you can end up with a cavity. Less sugar which spends less time on your teeth = fewer cavities!

And there’s another good reason to pass up chewy treats if you wear braces. Candy can get stuck under your brackets and wires, or be sticky enough to pull a bracket right off a tooth.

  • Is It Sour?

Sour candies get that intense, lip-puckering taste because they’re so acidic. What’s wrong with acids? Just like the acids made by bacteria, acids in food attack our tooth enamel, too.

Sour candies are hard on your teeth all by themselves. When you eat a candy that’s both sour (acidic) and gummy (sticky), all coated in sugar, that’s triple trouble!

  • Is It Hard or Crunchy?

Some kids like hard candies like lollipops and fruity drops because they last a long time. But that’s the problem. All that time a hard candy rolls around in your mouth is time spent bathing your teeth with sugar.

Thinking of shortening your sugar exposure by chewing hard candies? Also a bad idea! Crunching into a piece of hard candy can chip or crack a tooth and even damage fillings.

Crunchy treats can be hard on braces, too. Peanut brittle, nutty candy bars, candy apples, popcorn balls, or any hard or crunchy candy can damage your brackets and wires when you bite down.

Luckily, there are healthier trick-or-treating choices if you know what to look for. 

  • Soft Candies and Chocolates

A chocolate bar, a peanut butter cup, mint patties, and other soft candies won’t stick around on your teeth the same way chewy or hard candies do. No sour acids, either. And because dark chocolate has less sugar than lighter chocolates, it’s an even healthier choice.

Bonus: They’re easy to bite and chew when you wear braces!

  • Sugar-Free Gum

This treat is not only sugarless, but chewing it helps us make more saliva. Saliva washes away sugary food particles and helps neutralize the acids in the mouth. If you wear braces, check with Dr. Andrew Nalin to see if sugar-free gum is safe for your brackets and wires.

No need to skip the trick-or-treating this year. Occasional sugary or acidic treats can be balanced out with daily brushing and flossing, a healthy diet, and regular visits to your dentist for exams and cleanings. When you do enjoy a treat that’s sugary or acidic, there are tricks to help you keep your smile healthy and cavity-free.

  • Eat a treat or two with your meals instead of snacking through the day. You won’t be exposing your teeth to sugar for hours at a time, which means bacteria and acids won’t be haunting your enamel all day long.
  • Drink water. If you eat your candy with an acidic soda, you’re getting sugar + sugar + acids. That’s a scary recipe when it comes to healthy teeth! Water helps wash away sugar and acids—and, if you have fluoridated water in your community, you’ll be getting a bit of fluoride to strengthen your enamel, too.
  • Halloween is no time to ghost your toothbrush and floss. Be extra careful to brush and clean between your teeth after eating sweets. Wearing braces? Don’t forget to clean around your brackets and wires. Using aligners? Be sure to brush well after you eat something sugary before you replace them.

If you’re wearing braces this Halloween season, it’s important to avoid all the sticky, hard, and crunchy treats to keep your braces and your treatment schedule intact.

Any questions? Talk to Dr. Andrew Nalin at our Mount Vernon, WA office to learn the best ways to keep your smile looking boo-tiful all year long!

Eating and ClearCorrect™

October 22nd, 2025

You want to straighten your teeth because you know it’ll make your smile more appealing, be more comfortable, and improve your dental health. However, eating can be a big barrier to getting braces because of all the foods you need to give up for the months or years that treatment lasts. ClearCorrect is an alternative tooth-straightening option that doesn’t make you dread your new diet while you straighten your teeth. Here’s what you need to know about eating and ClearCorrect.

Eat What You Want

All kinds of foods are forbidden when you have metal braces because they can get stuck in the wires or cause brackets to pop off. That’s not a problem with ClearCorrect because you remove your clear aligners whenever you eat a meal or snack. That way, you can eat anything you want. You don’t need to avoid the following foods the way you do when you have metal braces.

  • Popcorn
  • Peanuts, nuts, and seeds
  • Meat on the bone, such as chicken wings and ribs
  • Sticky foods, such as toffee and raisins
  • Crunchy foods, such as apples and carrots
  • Stringy foods, such as celery and pineapple

Since you can eat whatever you want, you don’t need to avoid your friends and coworkers because of your ClearCorrect aligners. You can hang out with friends and go to business lunches without worrying about embarrassment.

Maintain Healthy Eating Habits

You can eat whatever you want without fear of wrecking your ClearCorrect aligners, but that doesn’t mean you should toss out your healthy eating habits. Dr. Andrew Nalin and our team recommend that you:

  • Eat high-calcium foods, such as low-fat yogurt and cheese, to support strong teeth.
  • Rinse your mouth with water after eating to get rid of excess carbohydrates on your teeth.
  • Limit consumption of sugary beverages and foods, such as candy, to keep sugar from settling on your teeth and feeding bacteria.

ClearCorrect treatment can straighten your teeth without making you give up your favorite foods or become a social outcast. Just take the aligners out of your mouth for meals and snacks and select healthy foods whenever possible, and you can enjoy yourself while your teeth get straighter.
