What is malocclusion?

March 18th, 2026

The term malocclusion refers to misalignment of teeth. You may have been born with malocclusion, so your teeth simply grew in crooked, or the misalignment and crowding of your teeth occurred over a period of time. Either way, not only can malocclusion pose cosmetic issues, but it can have a negative effect on your speaking and eating abilities as well.

Types of Malocclusion

Malocclusion encompasses multiple types and classifications of misalignment issues, including twisting or rotation of the teeth and molars that do not meet when you bite down. In some cases, the top front teeth are pushed outward in an upper protrusion.

In other cases, a misplaced midline results when the front top teeth don’t meet with the front bottom teeth. Transposition occurs when teeth protrude through the gums in a position where another tooth is supposed to be.

Practically any type of crowding or spacing issues, rotation or twisting of the teeth, or bite problem – including overbite, underbite, open bite, or crossbite – is included under the umbrella of malocclusion.

Malocclusion Classifications

There are three classifications of bite or misalignment problem.

  • Class 1 malocclusion: While the bite may be normal, the upper teeth overlap the lower teeth slightly. This is the most common type.
  • Class 2 malocclusion: Known as overbite or retrognathism, class 2 involves a severe overlap of the upper teeth and jaw over the bottom teeth and jaw.
  • Class 3 malocclusion: Known as underbite or prognathism, class 3 occurs when the lower teeth and jaw overlap the upper teeth and jaw. Thus, the lower jaw juts forward.

Causes of Malocclusion

The most common cause of malocclusion is genetics. However, there may be other causes, including the development of abnormally-shaped teeth, lost teeth, or impacted teeth; thumb sucking or overuse of a pacifier as a small child; having fillings or crowns that do not fit correctly; a serious injury that causes misalignment of the jaw; or developing a tumor of the mouth or jaw.

Treating Malocclusion

Orthodontic care at Nalin Orthodontics with Dr. Andrew Nalin is the main treatment available for malocclusion, which includes getting braces, Invisalign, or other corrective treatments. Treatment is ideal not just to have your smile improved, but because it makes the teeth easier to clean and maintain, lowers the risk of gum disease and tooth decay, and can even take pressure off the jaw and teeth.

Think about orthodontic treatment if you (or your child) display any signs of malocclusion. Early treatment of malocclusion during childhood can lessen expensive treatment later on.

St. Patrick's Day: Celtic pride, green shamrocks, and lucky charms!

March 11th, 2026

“St. Patrick's Day is an enchanted time -- a day to begin transforming winter's dreams into summer's magic.” Adrienne Cook

Lucky green shamrocks, leprechauns, and pots of gold – it must be St. Patrick’s Day! If you’re not Irish, how do you go about celebrating St. Patrick’s Day? It’s easy: You just put on one of those tall leprechauns hats, dress in green from head to toe, and wear one of those carefree pins that say “Kiss Me, I’m Irish”. On St. Patrick’s Day, everyone is Irish, and that is the universal beauty of the holiday. Celtic pride does not discriminate.

Wondering what our team at Nalin Orthodontics is doing to celebrate March 17th? Well, we’ve thought about doing everything from handing out lucky gold coins (you know, the fake ones that are made of chocolate) to shamrock stickers. Maybe we’ll even give away green toothbrushes and floss! You’ll never know unless you come in to see Dr. Andrew Nalin !

All kidding aside, St. Patrick’s Day is an important cultural and religious holiday. There are lavish parades and church services across Ireland on March 17th. Over time, however, the holiday has developed into a day to observe Irish culture in general. In places like England and the United States, where there is a large Irish Diaspora, the holiday has greater significance than other countries. From the streets of Boston to St. Patrick’s Cathedral in New York, it is a day of celebration, and many Americans of Irish descent will cook up a traditional meal of corned beef and cabbage.

So, to all of you with Irish ancestry, and to all of you who have decided to be Irish for the day, our office wishes you a Happy St. Patrick’s Day. Good luck looking for a pot of leprechaun gold, which is said to exist at the end of the rainbow. However, keep away from those sugary Lucky Charms; sweet cereals might taste good, but your kids’ teeth might not be feeling too lucky if they eat it for breakfast every day. Have a great St. Paddy’s Day!

What are lingual braces?

March 4th, 2026

Incognito™ lingual braces offer the effectiveness of traditional braces minus the look of a mouth full of metal. They’re placed on the back of your teeth and won’t be visible to others unless you have widely spaced teeth. Dr. Andrew Nalin would love to help you determine if this would be a good treatment option for you.

Benefits of Incognito Lingual Braces

For many patients, the biggest benefit of Incognito lingual braces is that they are rarely perceived by anyone. Patients are able to talk and smile without feeling self-conscious about wearing braces.

Another perk is that they are just as effective as standard braces. Patients enjoy the pleasing aesthetic aspect without compromising on time or results! Lingual braces are also a great option for patients who have plastic sensitivities or can’t wear other types of clear braces.

Who can get lingual braces?

Although many patients qualify for lingual braces, not everyone is a good candidate. The best candidates are teenagers and adults with normal-sized teeth and no bite issues. Children often have smaller teeth, so lingual braces may not be suitable.

If you’re thinking about correcting your smile but don’t want traditional braces, talk to Dr. Andrew Nalin or visit our Mount Vernon, WA office today. We can determine whether lingual braces are the right choice for you, so you can have the smile you’ve always wanted!

Brushing with Braces: How to Keep a Clean Mouth

February 25th, 2026

A clean mouth is a happy mouth. And when Dr. Andrew Nalin and our staff see you have a clean mouth, we are happy too. Of course, all of this should make you happy because you’re the one preventing sneaky little food bits from getting trapped under the wires of your braces.

Still, you need to be thorough with your brushing. When you have braces, you’re playing a game of hide-and-go-seek with everything you eat. Here are five tips to keep your mouth (and us) happy.

  1. How is brushing with braces like geometry? It’s all about the angles. Brush the tops of your teeth and braces with your brush angled down. Brush the bottom of your teeth with the brush angled up. Pointy brushes, aka interproximal brushes, are good for reaching the tiny spots around braces.
  2. Brush after every meal. If those sneaky little food bits hide in your mouth for very long, they’ll turn into plaque. And plaque is a sign of a very unhappy mouth.
  3. Brush one tooth at a time for at least ten seconds, and pay close attention to the spots where your braces touch your teeth.
  4. Fluoride is your new BFF. Make sure your toothpaste and mouthwash contain this cavity-fighting ingredient.
  5. Braces are no excuse not to floss. In fact, saying you can’t floss because you have braces is like saying the dog ate your homework. Dr. Andrew Nalin and our staff, like your geometry teacher, aren’t going to buy it. Be sure to floss after every meal.
