Before Your Visit

Before Your Visit

Haas Dental Associates has a few tips for making your next dental visit easy. We understand that you might have some worry around your appointment so being as prepared will help put your mind at ease. If you have any questions about your appointment, feel free to reach out to our team. We are happy to answer your every dental concern. No matter what type of service you need, we are proud to offer flexible scheduling. We make the safety and health of our patients our top priority, so if you or your child is unable to attend the visit, contact us for hassle-free rescheduling.

  1. If it is your first visit: We recommend arriving 10-15 minutes early and prepared in order to minimize hassle. Make sure to bring any needed dental documents and insurance information as well as any questions or concerns you have written out.
  2. If you or your child is receiving nitrous oxide: Nitrous oxide is a safe way to ease worries while allowing you to remain fully conscious. It is important that before your appointment, you inform us about any changes in you or your child’s health and medical condition, including any medication taken recently or respiratory issues. We also ask to arrive on an empty stomach, eating nothing 2-3 hours prior to the appointment.
  3. If you or your child is receiving conscious sedation: Unlike nitrous oxide, conscious sedation can cause drowsiness, which means if you are an adult, you will need to arrange transportation from the appointment. For children, the parent or legal guardian must remain at the office throughout the entire procedure, so plan accordingly. We ask that you or your child not eat solid foods for at least 8 hours prior to sedation, with nothing but water 5 hours before your visit. Before your appointment, we also require information regarding any medicines you are currently taking as well as any allergies/reactions you have to medicines.
  4. If you or your child is receiving outpatient general anesthesia: We ask you only consume clear liquids like water and Gatorade starting at 6 hours prior to your appointment. Arrange transportation to and from your appointment and know that if your child is receiving anesthesia, you will need to be there for the entire procedure. Dress in loose, comfortable clothes, and bring a list of any drugs taken as well as a comprehensive list of any drug reactions and allergies.
