 Trustindex verifies that the original source of the review is Google. I'm not going to lie, I had my wisdom teeth removed today and I don't remember much (which I'm honestly totally okay with!). The few moments of lucidity I did have however were filled with the nicest staff members and they were especially kind to me when I got nauseous and threw up. From the front desk staff to all of the assistants/nurses and Dr. Udy herself, I felt very cared for and would highly recommend them all to anyone! I'm a naturally anxious person and they made the experience honestly quite enjoyable. Thank you to all of the staff who helped me today! :)

Comprehensive Care · Specialized Treatments · Advanced Procedures

Oral surgery procedures for teens, adults, families, and referring doctors

From common extractions to advanced implant planning, Northwest Oral Surgeons provides focused surgical care in one O’Fallon office. Explore our core procedures below, then call our team to discuss scheduling, referral details, insurance information, and next steps.

Tooth Extractions & Wisdom Teeth

Wisdom teeth and other extractions often require careful planning, especially when teeth are impacted or when a patient is nervous about surgery. Our team helps patients and parents understand the diagnosis, anesthesia options, instructions, and recovery expectations before treatment.

Dental Implants

Dental implants can replace one or more missing teeth and may also support full-arch restorations or implant-supported dentures. Dr. Udy coordinates implant placement, extractions, and bone grafting when needed, while your restorative dentist completes the final tooth or prosthesis.

Bone Grafting & Implant Preparation

When the jawbone needs additional support before implant placement, bone grafting may help prepare the area for future treatment. Our office evaluates bone volume, anatomy, and implant goals to determine whether grafting, sinus lift, socket preservation, or ridge augmentation may be appropriate.

Jaw & Facial Surgery

Jaw and facial surgery may be recommended for concerns involving jaw alignment, facial trauma, pre-prosthetic preparation, impacted teeth, or oral pathology. These cases require thoughtful evaluation, imaging, and coordination with the patient’s dentist, orthodontist, or physician when applicable.

Permanent Solutions · Restore Your Smile

Planning dental implants around your long-term function

Dental implant treatment starts with understanding what needs to be replaced, how much bone support is available, and what type of restoration will be used after surgery. At Northwest Oral Surgeons, implant planning may include 3D imaging, digital scanning, bone grafting, guided surgical planning, and coordination with your restorative dentist.

For patients missing one tooth, several teeth, or a full arch of teeth, Dr. Udy can evaluate options such as implant placement, implant-supported dentures, and All-on-X treatment planning. The goal is to help you understand what is clinically appropriate for your case before moving forward.

Comfort First · Expert Removal · Prevent Future Problems

Wisdom teeth and extractions with clear guidance for families

Wisdom teeth often develop during the teen years and early adulthood, which is why parents and patients usually have important questions about timing, comfort, anesthesia, school schedules, and recovery. Our team explains the findings, reviews imaging, and helps families understand what to expect before and after treatment.

Northwest Oral Surgeons also evaluates impacted canines and other teeth that may require surgical exposure or extraction. If you have been referred by a dentist or orthodontist, call our office so we can help review the next scheduling step.

Advanced Technology · Precision Surgical Care

Technology and comfort support for surgical care

Surgical planning is easier to understand when patients can see what is being evaluated. Northwest Oral Surgeons uses advanced technology to support diagnosis, treatment planning, and coordination with referring doctors when needed.

Technology used in the office includes CS 9300 cone beam computed tomography, digital 3D intraoral scanners, panoramic x-ray radiography, and photogrammetry for precise multi-unit implant planning. For comfort, the team is trained to support IV sedation and general anesthesia within the office setting when appropriate for the procedure.

3D CBCT Imaging

Helps evaluate anatomy, surgical needs, and treatment planning details.

Digital Scanning & Guided Planning

Supports custom surgical stents, guides, and implant planning workflows.

Photogrammetry for Full-Arch Cases

Helps map multi-unit implant coordinates for custom prosthetic planning.

Sedation Support

IV sedation and general anesthesia support are available for appropriate surgical procedures.

What to Expect · Getting Started

Preparing for your first visit

Your first visit is designed to help Dr. Udy evaluate your concern, explain the diagnosis, and review treatment options. Some patients come in after a referral from a dentist or orthodontist, while others call because they have questions about wisdom teeth, dental implants, extractions, or another surgical need.

When scheduling by phone, our team can help you understand what information to bring, how insurance questions are handled, and whether a separate treatment appointment may be needed after the consultation. If IV anesthesia is planned, a preoperative consultation and physical examination are required.

Questions Answered · Helpful Information

Oral Surgery FAQ

When should I see an oral surgeon?

You may be referred to an oral surgeon for wisdom teeth, tooth extractions, dental implants, bone grafting, jaw surgery, impacted teeth, facial trauma, oral pathology, or other surgical concerns. If you are not sure whether Northwest Oral Surgeons is the right next step, call the office and our team can help guide you.

Do I need a referral to schedule with Northwest Oral Surgeons?

Many patients are referred by a dentist, orthodontist, or physician. Referral needs can depend on your concern, insurance plan, and the type of evaluation required. The best next step is to call 636-978-6967 so our team can confirm what information is needed before your visit.

What happens at the first visit?

Your initial appointment usually includes a consultation, review of your concern, discussion of diagnosis and treatment options, and review of any x-rays or referral information. Some situations may require a separate treatment appointment, especially when the treatment plan or medical history is more complex.

What sedation or anesthesia options are available?

Northwest Oral Surgeons supports IV sedation and general anesthesia for appropriate surgical procedures. The right option depends on your health history, procedure, and treatment plan. If IV anesthesia is planned, a preoperative consultation and physical examination are required.

When should wisdom teeth be evaluated?

Wisdom teeth are often evaluated during the teen years or early adulthood, especially when a dentist or orthodontist sees signs of impaction or limited space. A consultation and imaging help determine whether removal is recommended and what the timing should look like.

What is the first step for dental implants?

The first step is an implant consultation to evaluate your missing tooth or teeth, jawbone support, health history, and restoration goals. Some patients may need bone grafting or coordination with a restorative dentist before final implant treatment can move forward.
