What is an Orthodontist?
May 14th, 2012
An orthodontist is a dental specialist that has completed college, following college orthodontists are initially trained as dentists. After they have completed dental school, orthodontists attend two to three years of a residency program devised to orthodontic care. So, all orthodontists are dentists, however, not all dentists are orthodontists.
Dr. Randall Welser completed four years of college at Augustana before moving on to dental school. He attended Southern University School of Dental Medicine, which he attended for four years before attending St. Louis University for his two year orthodontic residency.
Dr. K. Kirby Marine attended Luther College for his undergraduate education. He then went to University of Illinois at Chicago where he received his degree in dental science. After working as a practicing dentist for a few years, he then attended the University of Minnesota for his orthodontic residency.
After receiving the additional terms of training and education, an orthodontist has the skills that are needed to correct misalignments of teeth and jaws.
What Causes Crooked Teeth and Bad Bites?
The simple answer is that we do not know. Most often malocclusions (bad bites) are a result of a complex interaction of multiple factors that influence growth and development. As said, it is almost impossible to describe a specific cause. An estimated 65% of the population could benefit from orthodontic care.
Although it is difficult to know the precise cause of most malocclusion, we do know, in general, what the possible causes are and these factors must be considered when planning orthodontic care. Causes of malocclusion include: dental/facial trauma, missing teeth, malformed teeth, extra teeth, ectopic eruption of teeth, impacted teeth, genetic influences, environmental influences, and sucking habits just to name a few.
The good news for individuals with a malocclusion is that orthodontic care can improve the alignment and fit of the bite almost every time!



The number one goal of orthodontic treatment is to give you or your child a good bite, meaning straight teeth that work well with the teeth in the opposite jaw. A good bite makes it easier for you to eat, chew, and speak. It can enhance your dental health and your overall health, and may well improve your self-esteem. As a part of your comprehensive dental health care plan, orthodontic treatment can help you retain you teeth—and your smile—for a lifetime.

Invisalign clear aligners can be a great option for improving the look of your smile.
There are several reasons why some people's teeth grow in crooked, overlapping, or twisted. Some people's mouths are too small for their teeth, which crowds the teeth and causes them to shift. In other cases, a person's upper and lower jaws aren't the same size or are malformed. Most often, crooked teeth are inherited traits just as the color of your eyes or hair. Other causes of crooked teeth are early loss of baby or adult teeth, undue pressure on the teeth and gums, misalignment of jaw after facial injury, or common oral health problems in children such as thumb sucking, tongue thrusting, or prolonged use of a bottle or pacifier.

"Dentists, Orthodontists, they're all the same right?" We hear our patients asking this question as they wonder about the difference between an orthodontist and a dentist. Before becoming an orthodontist Drs. Randall Welser and Kirby Marine started out in dental school and earned a DDS (dental degree), just like your dentist. After dental school however, Drs. Randall Welser and Kirby Marine decided to learn more about orthodontics, which is one of nine specialties within the dental field. So they stayed in school for a few more years and became an expert in orthodontics, which focuses on tooth and jaw alignment and bite problems like overbites and under bites.
