At OHSU's Department of Oral & Maxillofacial Surgery, we pride ourselves on giving the best patient care and best quality of surgical service possible. We believe that communication is the key to a good doctor-patient relationship. This begins with the initial consultation. A thorough review of your medical history is essential in providing you with the safest and best care possible. If you have an extensive medical history, consultation with your physician and need for further studies may be required prior to your treatment. We are always happy to answer any questions you may have and want to make sure that you have a good understanding of the care that is provided for you. We also communicate and work closely with your restorative dentist and/or physician to come up with a treatment plan that will benefit you the most. There are also many cases where we are able to provide you with a consultation and surgery on the same day. Please contact us at 503-494-8916 to schedule a consultation. We appreciate the opportunity to participate in your care.


OHSU's Department of Oral & Maxillofacial surgery is open Monday - Friday from 8:30 am until 4:00 pm. We will make every attempt to schedule your appointment as promptly as possible. If you have pain or an emergency situation, every attempt will be made to see you that day. We do have a doctor on-call after hours and on the weekends to help answer your questions.

We try our best to stay on schedule to minimize your waiting. Due to the fact that the Department of Oral & Maxillofacial Surgery provides surgical and emergency services, various circumstances may lengthen the time allocated for a procedure. We appreciate your understanding and patience.


Thank you for choosing us as your oral health care provider. We are committed to your treatment being successful. Please understand that payment of your bill is considered a part of your treatment. The following is a statement of our Financial Policy.

Regarding Insurance

Please be prepared to pay any co-payments, deductibles and estimated patient shares not covered by insurance at the time of the visit. All patients not covered by insurance or having a cosmetic procedure done should be prepared to pay the full estimated cost for the procedure(s) at the time of service. If there is any remaining balance, full payment is expected upon receipt of our statement. Other options for payment must be made in advance of a surgery date.

We ask that you pay, on the day of surgery, that percentage we estimate will not be covered by your insurance company(s), as well as any deductible not yet met. Please remember that we can only estimate the amount to be paid by an insurance company, as they make payments based on their fee schedule. Their fee schedules are not a standard of our profession and may differ from our charges. While we help you in every way possible to obtain your maximum allowable insurance benefits, the insurance contract is between you and your insurance company, and does not replace your responsibility for your account. If your insurance company has not paid your claim within 45 days, we will ask you to pay the balance in full. It is the responsibility of the patient, not the provider, to know what is covered and what is excluded from his/her plan. We may submit an insurance claim as a courtesy to our patients with insurance. If we are unable to verify insurance benefits with the insurance company, the account will be considered private pay and the payment requirements listed below will be applicable.

Private Pay

Accounts for which we are not submitting a claim to an insurance company will be considered private pay. We ask that you pay your charges in full on the day of treatment. If necessary, a payment arrangement may be discussed with a Financial Coordinator, however, all payment plans are subject to credit approval.

Usual and Customary Rates

Our practice is committed to providing the best treatment for our patients and we charge what is usual and customary for our area. You are responsible for payment regardless of any insurance company's arbitrary determination of usual and customary rates.


If you need to contact your doctor after hours, please call the OHSU operator at 503-494-8311 and ask that the Oral & Maxillofacial surgeon on call be paged.


Thank you for choosing the OHSU Oral & Maxillofacial Surgery Clinic for your treatment, which continues until healing is complete. If you have questions about your treatment, or your post-operative care is marked by excessive pain, swelling or bleeding, do not hesitate to call us immediately.

During clinic hours (8:00 am - 4:00 pm), please call

(503) 494-8916. After normal hours, or on weekends and holidays, please call (503) 494-8311 and ask for the Oral & Maxillofacial Surgery resident "on call."


SWELLING and BRUISING - Discoloration of the skin of the face and neck may occur and is normal. Typically swelling reaches its maximum 2 to 3 days after surgery and may last 7 to 10 days. Ice packs may be used to improve your comfort, and may be applied for the first few hours (30 minutes on, 30 minutes off) following surgery.

BLEEDING – Bite on the gauze, unless otherwise instructed by your surgeon. Gauze should remain in your mouth at the end of the surgical procedure for 20 minutes. If bleeding persists, place new dampened gauze over the bleeding sites for an additional one-hour. This may be repeated several times. (IMPORTANT: The gauze must exert pressure on the bleeding sites to stop the bleeding.) Some blood will ooze from the area of surgery for 24 to 36 hours and is normal. Keep your head & chest elevated for the first 24 hours after surgery.

DISCOMFORT – Some discomfort is normal following surgery and will be greatest during the first 24 hours immediately after sensation returns to you mouth. The discomfort can be controlled but not eliminated by the pain medications you have been prescribed and these should be started well before the local anesthesia has worn off.

MEDICATIONS – It is essential to take all medications as directed.

Pain medications can cause nausea; therefore it should be taken with a full glass of water and some food.

IMPORTANT: Sometimes antibiotics reduce the effectiveness of birth control pills. If you are using medication for birth control and are prescribed antibiotics, you should use alternative methods of birth control for 21 days.

DIET – It is important to get adequate nutrition after surgery to help the healing process. Fluids are especially important. Eat normal meals as soon as possible. Cold, soft food such as ice cream or yogurt may be the most comfortable for the first day. Refrain from alcohol if taking pain medication.

ORAL HYGIENE – Do not rinse your mouth on the day of surgery. On the evening of the day of surgery, you may rinse with warm salt water (1/2 teaspoon salt to an 8 oz. glass of warm water following meals). Brush your teeth gently avoiding the surgical area.

REST – Avoid strenuous activity for the first 12 to 24 hours after surgery, since this may promote bleeding by dislodging the blood clot.

STIFFNESS –You may experience jaw muscle stiffness and limited opening of your mouth following surgery. This is normal and should improve in a few days.

BRUISING –You may experience some mild bruising in the area of your surgery. This is a normal response in some persons and should not be a cause for alarm. It will disappear in 7 to 14 days.

SMOKING – Refrain from smoking for 4 to 5 days. Smoking can cause bleeding; it interferes with the healing process, and may lead to a very painful post-operative complication called a “dry socket”.

ACTIVITY and DRIVING – Do not drive, operate machinery, or engage in contact sports when taking narcotic pain medication, or for 24 hours following IV sedation.
