What is malocclusion?

September 17th, 2025

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 Teguis Orthodontics with Dr. Teguis 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.

Thanks to Invisalign®, you can have a perfect smile without metal wires or brackets!

When it comes to straightening your smile, our team at Teguis Orthodontics knows that having a mouth full of metal braces may not be your idea of fun. Luckily for you, Dr. Teguis can offer a cosmetic alternative: Invisalign!

Using a series of clear, comfortable, and completely customized aligners, you can get the smile you’ve always wanted without traditional braces.

Since Invisalign aligners are discreet, they’re hardly noticeable when you speak and smile, and because they’re removable, you can eat and drink whatever you want. Just remember to brush and floss before putting your aligners back in! Treatment with Invisalign is just as effective as with metal braces, and the results are just as amazing!

Labor Day: Our favorite holiday to rest!

August 27th, 2025

Labor Day, celebrated on the first Monday each September here in the United States, is a holiday devoted to the American working community. The purpose of the holiday is honoring the country's workers and their contributions to the strength of our country as a whole.

How Labor Day Started

There is actually some debate as to the origins of Labor Day. It is uncertain whether Peter McGuire, a cofounder for the American Federation of Labor, or Matthew Maguire, who was the secretary of Central Labor Union of New York, had the great idea. However, the Central Labor Union's plans were what launched the first Labor Day in America.

The First Labor Day

The very first Labor Day was celebrated on September 5th, 1882. The Central Labor Union then held annual celebrations on September 5th for what they called a working man's holiday. By the year 1885, the Labor Day celebration had spread to many different industrial areas, and after that it began spreading to all industries in the United States.

Labor Day Today

Labor Day today is a huge United States holiday during which we honor the country's workers with a day of rest and relaxation or a day of picnics and parades. This holiday is truly one to honor the many people who work hard to contribute to the economic well-being of our great country!

Our team at Teguis Orthodontics hopes all of our patients celebrate Labor Day, and every holiday, safely and happily. Whether you stay in the Biddeford area, or travel out of town, have fun, and don't forget to brush!
