Dentist Staff in Olean, NY | Dr. John C. Gengo, DDS


Once you make an appointment at our office, that time is exclusively reserved for you. If, for some reason, you can no longer make your appointment, please let us know so that we may be able to help another patient in the time allotted.

  It is also helpful if you come 15 minutes prior to your scheduled appointment to fill out any paperwork.

  Please be aware that if you are more than 15 minutes late, you may be asked to reschedule your appointment out of courtesy to the patients that are scheduled after you.


Payment is expected at the time services are rendered, including any co-payment or deductibles (amount not covered by your insurance). For your convenience, we accept cash, checks, MasterCard, Visa, Discover, and CareCredit.


If you have dental insurance, please bring your information with you during your visit. Our office staff will work hard to get you the maximum amount of coverage allowed by your plan.

Pre- and Postoperative Instructions

Please follow the instructions below when you receive a tooth extraction. Dr. Gengo will also provide you with additional instructions.


  Illness: Please let us know if you become ill before your appointment, in case we need to postpone the procedure.

  Food: Do not drink any alcoholic beverage 48 hours before your appointment, as alcohol can cause excessive bleeding.


  After your surgery rest for around 6-12 hours. This allows your body to have time to heal. Excessive exercise or movement can cause your incision to open and bleeding to occur.

  A moist gauze has been placed on the surgical site; make sure you replace the gauze every 15-20 minutes and replace with a new piece of moist gauze until bleeding has stopped. If bleeding persists for more than an hour, contact Dr. Gengo immediately.

  A soft diet is recommended for at least a week after you have had your surgery. Avoid eating anything crunchy or that has seeds.

  Do not rinse your mouth with mouthwash on the day you had your surgery. Do not brush over the surgical area until after your first post-surgical exam.

  Do not smoke while you are in the healing stage. Smoking will cause the healing process to slow down and cause less than optimal results.
