Before Intravenous Anesthesia Sedation

Top Oral Surgeons & Dental Implant Specialists in St. Louis, MO & Belleville, IL

In preparation for your upcoming surgery at MOSAIC, we ask that you adhere to the following guidelines to ensure your safety and the effectiveness of the intravenous anesthesia sedation.


  1. Please refrain from consuming food or drinks, including water, for a minimum of eight hours before your scheduled surgery time.
  2. If you are a smoker, we strongly advise you to abstain from smoking for at least 12 hours before your procedure. For your overall health and surgery success, it would be advantageous to reduce or ideally quit smoking as far ahead of your surgery date as possible.
  3. A reliable adult is required to accompany you to MOSAIC on the day of your procedure. This individual must stay in the office throughout your surgery, provide transportation for you post-procedure, and commit to remaining with you for the first 24 hours after surgery.
  4. Given the lingering effects of anesthesia, patients must not operate vehicles or any form of machinery for a full 24 hours following the surgery.
  5. Dress appropriately on the day of your surgery. We recommend loose, comfortable clothing with short sleeves to facilitate monitoring. Also, for safety, it's crucial to wear supportive, secure shoes like lace-up sneakers.
  6. Please remove all contact lenses, jewelry, and dentures prior to surgery.
  7. Refrain from wearing lipstick, heavy makeup, or nail polish on the day of your surgery.
  8. Your health is our priority. If you're experiencing any illness symptoms such as a cold, sore throat, or flu-like signs, kindly inform our office.
  9. If you are on routine oral medication, please consult Dr. Noble before your surgery date for detailed instructions.

By following these guidelines, you will greatly contribute to the successful outcome of your procedure. Your safety and comfort are our top priorities at MOSAIC, and we appreciate your cooperation.

My husband was referred here for a tooth extraction and the staff and Dr Gustave were amazing. They explained everything and took the time to answer all our questions. I will definitely use this office again if we need any dental surgeries.

I am so thankful and grateful I found Dr. Morris and the entire team! They are excellent with communication, efficiency, and compassion. Dr. Morris did my extraction and placed an implant. The entire process was so much easier And less painful than I expected! They most definitely exceeded my expectations! I highly recommend them!

I live in Mt. Vernon, IL & was referred to Dr. Hesterberg to have a tooth extraction. He made me feel at ease & explained everything he would do. The procedure was pain free. At my follow up today he said it was healing perfectly. I highly recommend him & love that he makes you feel like a friend, instead of a patient.

I had an excellent experience here. From the initial consult to the procedure itself, the staff was friendly, calm, and very knowledgeable. Dr. Hesterberg was incredible and explained everything ahead of time, answered all my questions, and made sure I was comfortable throughout. The surgery went smoothly and recovery has been exactly as they described. I would absolutely recommend this office to anyone needing oral surgery.

I've had one molar extraction done here, a couple of years ago. Im having another one done, with an implant in a couple of weeks. These are the best people to work with! Everyone explains things so completely. When I had my prior extraction, I had little to no pain or bleeding afterwards. Dr. Noble is wonderful!

If you’re needing an oral surgeon, Dr. Noble is the man I’d recommend. Doc has removed a number of teeth, and placed a couple implants for me; and I have nothing but good things to say about not just the Dr, but his front office help is great! Actually, long ago I saw Dr. Hesterberg, and he was awesome as well! He removed my wisdom teeth, although his old office help needed some retraining in compassionate care. This MOSAIC office is top notch!! Don’t hesitate to visit this office, I’m getting ready to have Dr. Noble place more implants, and I know it will be done professionally, and I’ll receive the very best care! Update 12/17/25 had 2 additional implants placed, another excellent experience!!!

Dr Gustave is AMAZING! He is so kind and caring. Daughter had all 4 wisdom teeth cut out with general sedation took about 45 mins start to finish! His staff and nurses are WONDERFUL and kind as well. They made my daughter and us feel at ease! Blessed we had the BEST!

I had a dental implant done by Dr. Hesterberg. I have a very sensitive mouth and I am always scared to get dental work done. He did an amazing job, and was very gentle! I would 100% recommend going here. I had absolutely no problems and hardly any pain even the next day.

The doctors in this practice are professional , highly educated , and experienced . I highly recommend using this dental surgery practice . I get anxiety every time I go to the dentist, but Dr. Hesterberg has always make my surgical experiences over the last 10 years very comfortable and pleasant for my tooth extractions, implants and bone grafts . Dr Hesterberg and his staff are very diligent on post operative follow up as well . Well worth my 45 minute drive to get the best dental care .

On 11/7/25 I had two teeth removed by Dr. Hesterberger. Being a nurse, I am typically the calm voice my patients hear. In this case, Dr. Hesterberger and his staff were the calm I needed that day! My procedure went well and everything was explained by Dr. Hesterberger as we went along. I highly recommend the Belleville office because they genuinely care about you and it shows in their actions!
