Underbite

Periodontics and Implant Dentistry in St. Louis, MO

An underbite occurs when your lower teeth close over the top of your upper teeth. Underbites can cause difficulty chewing and speaking.

Caused by a misalignment of the jaw, an underbite can be corrected with a range of treatments to improve your comfort and appearance.

So how do I know if I need treatment for an underbite?

If Your Underbite Is More Than A Cosmetic Concern, You May Need To See An Othodontist

Do You Have Issues Eating or Speaking?

An underbite can interfere with normal daily activities, including chewing and speaking.

Do You Suffer from Chronic Pain?

For some patients, underbites cause chronic jaw pain, as well as head and earaches.

Do You Have Breathing Difficulties?

Underbites can also affect your breathing, causing chronic bad breath, sleep apnea, and snoring.

What does an underbite look like?

Underbites Have a Distinctive Appearance

Clinically referred to as a Class III Malocclusion, an underbite occurs when the bottom teeth noticeably protrude beyond the upper teeth.

What causes an underbite?

Genetics Play A Major Role In Whether You Develop An Underbite

If one of your parents or grandparents had an underbite, there is a much larger chance that you will, too. In addition, certain ethnic groups are more likely to develop underbites, including those of Asian descent.

A famous example of the genetic nature of this trait is the “Habsburg jaw.” Many generations of the royal Habsburg family in Europe were known for their distinctive protruding lower jaws, which are believed to have been the result of an underbite.

Is there anything else that can contribute to an underbite?

Certain Environmental Factors Can Cause An Underbite

Tongue Thrusting

Constant thrusting of the tongue against the teeth can move your smile out of position and cause an underbite.

Childhood Habits

Habits such as thumb sucking and pacifier use in early childhood can also affect the way the jaw develops.

Mouth Breathing

Breathing through your mouth forces the tongue to rest against the lower jaw and increases the chance of an underbite.

Are underbites common?

Underbites Are Much Less Common Than Overbites

*According to the Journal of Advances in Medicine and Medical Research

What do I do if I suspect I have an underbite?

Your Dentist Can Diagnose Jaw Issues During A Routine Exam

In most cases, an underbite is easy to identify with a simple visual exam. However, your dentist or orthodontist will likely perform a complete evaluation of your teeth and jaw to determine the severity of your condition.

During the appointment, your dentist may take x-rays, photographs, and impressions to examine the specific relationship between your teeth, jaws, and head.

Is there any way to prevent an underbite from forming?

Early Intervention May Help A Child Avoid An Underbite

Limit Pacifier and Bottle Use

Parents of young children can help their child’s jaw form properly by limiting their pacifier and bottle use. Speak to your doctor or a dentist about the best time to begin this process.

Treat Mouth Breathing

If you notice your child snores or breathes through their mouth, you may be able to prevent issues in jaw development by treating these concerns early.

Is it really that important to get my underbite fixed?

An Underbite Can Have A Major Impact On Your Daily Life

“In its most severe form, the Class III malocclusion can be functionally and/or socially debilitating.”

-Family History and Genetics of Mandibular Prognathism

Braces Are The Most Common Treatment For An Underbite

The most commonly used treatment for underbites and other bite issues is orthodontics. Metal braces can adjust the position of teeth and improve jaw alignment to address an underbite.

Are there other options?

Your Orthodontist Can Find The Right Treatment For You

Aligners

For minor underbites, clear aligners, such as Invisalign®, can provide results.

Special Appliances

Devices, such as expanders, retainers, or headgear, may be used to treat an underbite.

Surgery

Severe underbites may require surgery. However, jaw surgery is typically only performed as a last resort.

How do I plan my underbite treatment?

Schedule an Appointment

Depending on the severity, an underbite can have a serious impact on your oral health and quality of life. Scheduling an appointment with a doctor is the best way to find out whether you need treatment.

  I can’t say enough great things about the staff here. Friendly, kind, compassionate, patient, empathetic and above all - amazing at their jobs. Front desk staff, billing staff, treatment coordinator, assistants and of course Dr. Schlaikjer - thank you so very much for making the extraction, bone graft and implant process the best experience possible for a very anxious person. 🙌🏼👏

  If I could leave more than 5 stars I would. Alyssa has been amazing at every appointment. She eases my fears before I can even express them and answers every question I have. I cannot rave enough about my experience. I never dread my appointment, which I cannot say the same about my regular dentist. Thank you so much for your amazing care!

  Long overdue review of this excellent practice. I have had four separate procedures over the last 18 or so months, All utilizing IV sedation. As a retired nurse I was very concerned that best practices were implemented for patients under conscious sedation. Dr. Schlaikjer has a crash cart with the appropriate reversal agents and code supplies. The monitors in the room were the same I used in the critical care setting. The Dr is ACLS certified and his staff are BLS certified. The staff including the front desk were top notch. The ladies at the desk went above and beyond helping me with my insurance claim. Both my dentist and orthodontist recommended Dr. Schlaikjer and I am so grateful they did.

  Dr. Justin Schlaikjer and his team are exceptional—thorough, gentle, and genuinely caring. My gum graft procedure went smoothly with excellent results and minimal downtime. Their kindness and non-judgmental approach make every visit a positive experience. Highly recommend!

  I’ve had a gum graft, bone graft and implant done by Justin and I am extremely satisfied. It’s been a year since my implant and any dentist or orthodontist that sees my implant compliments it and the healed tissue around it. Very minimal pain from the surgeries but the healing process is kinda long. Overall 10/10 experience and I recommend anyone that needs a graft or implant to go to Justin.

  I have a been a practicing Dental Specialist for over 30 years in South County. I am only treated by the best people in the field. I was blown away by how easy it was  having implants placed Dr Schlaiker and his trusty Robot. In my case I had implants replacing congenitally missing molars on both sides of my lower jaw. I had seen an implant surgeon previously who thought  it was too close to the nerve to be done (which could have left my lip permanently paralyzed) . After having the 3D CBCT taken and then evaluated by Dr Schlaiker  he assured me that with the use of his Robot technology it was indeed possible. In fact, he could do it all in one appointment  under IV sedation!!! Yesterday morning I had the procedures performed with zero discomfort! I am the typical male and am terrified of medical and dental procedures that I am awake for. I did not remember anything! Last night my wife told me I had her stop at the Steak and Shake for a milkshake after the appointment. I did not even remember that!! I took the pain medicine prescribed last night and nothing this morning. I am sitting here eating ice cream :) Life is good. Thank you to Dr Schlaiker and his amazing office staff (including the robot) for making what could have been a scary appointment….enjoyable!

  Wonderful people. Dr S carefully explains every procedure. It's weird, but my two favorite Docs are my periodontist and my urologist. My teeth and gums are in much better shape than when I first came in a few years ago.

  Dude. I was referred to Dr. Justin for gum grafting. I was like “another waste of money on something hooey”. Boy I was wrong. He did his work which took about 2 months for the whole two part procedure and wow. What a difference. My gums look all shiny and new. As if I never had a recession. Loved it. Now I want to do the rest of my teeth/gum 😂😂. Looks really nice.

  By far, the BEST experience I’ve ever had at a medical office. The staff/doctor was so accommodating, and made me feel super welcome and comfortable. At one point during my visit I told them I felt like I was at a spa! They treat their patients so well and give you their undivided attention. I was dreading this visit, but it was actually enjoyable! Dr. Schlaikjer was very informative and took his time, he was funny (as well as the staff), and I know I can trust him, which can be hard to find when it comes to healthcare. They truly, truly care about their patients, and I will definitely be back.

  Dr Schlaikjer and his team did outstanding job! I was very impressed from start to finish. After I talking to my friends and intervjuing several oral surgeons, I was pleased that I chose Dr Schlaikjer and his team. I could not have made a better choose. I wish, I could give this place more than 5 stars! Can not thank them enough. I had an extractions, 5 implant placed and bone graft done.Everything was amazing. He and his entire team are incredibly kind, helpful and attentive and they make you feel like you are visiting a friend rather than a surgeon. No better place to go for a dental extraction and tooth implants. As good as it gets. I HIGHLY recommend this place to anyone who is need of this type of service. I am very happy with my dental implants and I will be forever grateful!

  I was referred by my dentist who gave Dr S a rave review. After a thorough examination it was determined that my bone had to be built up to, accommodate an implant. It was a difficult task but Dr S handled it with expertise, compassion and an explanation of each and every procedure before he began. After major oral surgery he sent me home with his cell phone number to call if I was in pain.  I have the utmost confidence  in dr S  and encourage anyone needing a Periodontist to go to him.

  My son was involved in a car accident and had to have gum grafting. Dr Schlaikjer and his team were very informative, professional and went out of  their way to make my son and I feel comfortable and important. They are very personable and easy to talk to. My son has had great results with his procedure and we are so thankful to have found Dr. Schlaikjer!

  Dr Schlaikjer is very skilled and it is apparent when you are in his care. Always felt comfortable. Gum graft went super well and exceeded expectations. This sort of stuff is never fun, but if I had to get periodontal work again, I know where I would go.

The entire team, from Danyell, to Natasha, Ashley and Dr. Schlaikjer took the time to meet with me, explain everything as they went along and calmed my nerves. I highly recommend his services. Top notch!
