Patient Information


Oral and maxillofacial surgery requires up to 6 additional years of hospital based surgical and anesthesia training after graduating from dental school. As an oral and maxillofacial surgeon, Dr. Elder and Dr. Roth are extensively trained in maxillofacial trauma, facial reconstruction, orthognathic surgery, preprosthetic surgery, temporomandibular joint surgery, aesthetic maxillofacial surgery, craniofacial surgery, exodontia and other surgery as it pertains to the specialty.


Before surgery the doctor will examine your mouth and discuss the findings with you. This examination will include x-rays and a complete health/medical history with particular attention to allergies, medications or health problems that might affect surgery and/or the administration of anesthesia. The doctor will examine your mouth for any signs of swelling or infection, and check your blood pressure and other vital signs. It is important that you provide complete information, including the names and dosage of all medications you are taking, so an accurate assessment of your health can be established prior to recommending surgery.


Modern anesthesia technology now makes it possible to perform even complex surgery in the oral and maxillofacial surgery office with little or no discomfort. During surgery, one or more of the following is used to control pain and anxiety: Local anesthesia that numbs the surgical area; nitrous oxide-oxygen (sometimes called "laughing gas") for analgesia to relax you; intravenous sedation for increased relaxation; and general anesthesia that puts you to sleep. The surgeon will discuss the available anesthetic options and will recommend the most appropriate choice to ensure your comfort during the procedure. In addition, practicing Oral and Maxillofacial Surgeons must comply with individual state rules and regulations on anesthesia administration. As a member of AAOMS, our doctors must periodically undergo an onsite anesthesia inspection and reevaluation as part of association's office anesthesia evaluation program. AAOMS requirements are strict and often exceed those mandated by the state law.

Instruction For Care Of Mouth After Extraction

1.  DO NOT RINSE MOUTH TODAY.  Tomorrow rinse mouth gently, especially after meals.  Use one-quarter teaspoon of salt to a glass of warm water.  Continue rinses for several days.  Brush and floss as usual the day after.  Do not use mouthwash!

2.  BLEEDING.  If persistent bleeding occurs, dampen tea bag, place on extraction site, bite firmly for 30 minutes.  Repeat if necessary.  If bleeding continues, contact the office.

3.  SWELLING.  Ice Packs, double zip lock baggies with crushed ice, frozen peas, frozen corn, wrapped in a soft cloth or cotton tee shirt should be applied to the face, 20 minutes on and 20 minutes off, as much as possible for the first 48 hours.  Warm moist heat may be applied after 48 hours to relieve muscle soreness and stiffness.

Surgical Removal Of Wisdom Teeth

“Wisdom teeth” are a person’s third and final set of developing molars that are in the posterior of the mouth behind the 2nd molars.  Typically most people will have four wisdom teeth one located in each corner of the mouth and only very few people have the space needed for wisdom teeth.  Wisdom teeth will often be impacted in the bone preventing them from properly erupting within the mouth.  The impacted teeth will need to be removed to prevent problems that may come up in the future as well as relieve any pain.

Dental Implants

Dental implants have enhanced the quality of life and are frequently the best treatment option for replacing missing teeth. Injury, periodontal disease or tooth decay can all lead to loss of teeth. This experience can be traumatic and affect self-confidence as well as contribute to further dental problems. Dental implants are long-term replacements and a practical solution to what may feel like an overwhelming dilemma.  A dental implant is essentially a man-made tooth root composed of titanium metal that is placed beneath the gum and fuses to the bone in the jaw. These implants resemble the natural form of a tooth root. They are designed to function like natural teeth and give a person the ability to eat anything and smile with confidence.

Bone Grafting

Bone grafting is a procedure performed to reverse bone loss caused by periodontal disease, infection, or trauma.  Bone loss is accelerated when teeth are extracted and nothing is done to prevent the surrounding bone from collapsing. Dental implants are beneficial in such situations to prevent the defect that would normally develop when teeth are missing. Bone grafts are used to preserve the bone needed for implants and the techniques to replace bone tissue will depend of the size of the defect and the location within the mouth.

Facial Trauma

Facial trauma can consist of many situations such as facial lacerations, intraoral lacerations, knocked out teeth, fractured facial bones, and fractured jaws.  Our surgeons are trained and highly skilled to perform the proper treatment of each individual facial trauma. 

Temporomandibular Joint Disorders (TMJ)

TMJ disorders are a group of complex problems of the jaw joint.  The jaw has muscles and joints working together and a problem with either one can result in stiffness, headaches, pain, bite problems, clicking sounds, or locked jaws.  Some behaviors that can lead to TMJ disorders are teeth grinding and clenching, habitual gum chewing or fingernail biting, trauma to the jaws, stress, dental problems and misalignment of the teeth.  There are various treatment options and our doctors can perform a proper evaluation to confirm diagnosis of TMJ disorder and will determine the proper treatment.

Corrective Jaw Surgery

Orthognathic surgery is a corrective facial surgery performed on the bones of the jaws to reposition misaligned jaws.  This surgery is often done in conjunction with orthodontic treatment to straighten the teeth. People who often require repositioning of the jaw are ones who have difficulty in chewing, biting, or swallowing, speech problems, TMJ pain, open bite, protruding jaw, and or breathing problems.  If you are a candidate, a consultation should be scheduled in order to evaluate and determine the proper treatment for each patient.

Oral Pathology

Oral pathology are diseases affecting the oral and maxillofacial area.  Identification of such diseases can be seen by any alteration of the smooth, coral pink skin lining the inside. The change of appearance of the skin could be a sign of an oral pathology and the most serious of these disease is oral cancer.  There are multiple signs of oral pathology such as reddish or whitish patches in the mouth, a reoccurring sore that bleeds easily, a lump, thickening of the skin lining the inside of the mouth, chronic sore throat, and difficulty in chewing or swallowing.  It is important to be examined if you think you may have any of these signs.


In most cases, most of our invasive procedures are performed under local anesthesia, laughing gas (nitrous oxide/oxygen analgesia) or IV sedation. Our doctors will discuss which type of anesthesia is best for you and your particular needs.
