Frequently Asked Questions (FAQs)

How can we help you?

We are happy to answer questions about our services and procedures.

These are a selection of some common questions that patients have. If your question isn't answered here, please contact our office. It's important to us that our patients understand their dental care.


When planning for oral surgery, it’s important to factor in recovery time so you can schedule your procedure accordingly.

Exactly how long recovery takes will depend on you and your unique needs. Some surgeries allow you return to work the same day. Others require more recovery time, and some patients heal faster than others.

More involved procedures require two to three days of recovery time. In this case, your surgery can be performed on a Friday so you will be able to go back to work on the following Monday.

To minimize recovery times, please follow all post-procedure guidelines provided by our office. If you have been prescribed antibiotics, take them as directed until they’re finished.

If you are uncomfortable, we recommend taking over-the-counter anti-inflammatory medications like Motrin. In some cases, stronger pain medication is needed, and Dr. Um will determine if it’s warranted and safe for you.

Our team at Lake Forest Oral Surgery wants you to have a successful procedure with the shortest recovery time and the best possible outcome. We will do whatever is necessary to keep you comfortable while you’re here and provide you with the support you need during your recovery.

Please call us if you have questions about recovery time for your specific surgery. 

Wisdom Teeth Extraction

Also referred to as third molars, wisdom teeth are the teeth farthest back in your mouth. Because of their location, they can be difficult to clean adequately, making them prone to infection.

Since they are the last teeth to emerge in your late teens or early 20s, there’s not always sufficient space for them to erupt correctly. This can cause them to get stuck in the gums and erupt only partially or not at all.

Some wisdom teeth are involved with cysts and tumors that can lead to jaw fracture and even partial removal of the jaw. In some instances, a wisdom tooth puts pressure on the second molar (the adjacent tooth) and causes resorption (shrinking) of its root.

There is also a risk of nerve injury if the roots of wisdom teeth continue to develop and become entangled with the nerve inside the jaw that provides sensation to your lower lip, chin, and cheek. If the root grows around the nerve, injury can occur, resulting in permanent numbness.

If your dentist has referred you for wisdom teeth extraction, please call Lake Forest Oral Surgery to arrange an initial consultation. Dr. Um will evaluate your oral health, answer your questions, and make recommendations that are appropriate for your needs. 

Dental Implants

If you are considering dental implants, the first step is an evaluation with Dr. Um at our Foothill Ranch dental office. The most important consideration is that there be enough healthy bone in which to place the implant.

In some cases, an implant can be placed immediately after a tooth is extracted; however, for some patients, we may need to take steps to “rebuild” jawbone to provide a solid base for the implant.

Dr. Um uses modern 3-D imaging technology to determine the proper placement of your implant for optimal results. Knowing exactly where to place the implant results in an efficient procedure, less invasive treatment with minimal discomfort, and faster recovery times.

Healing typically takes several months but the exact time is different for each patient, depending on the hardness of the bone. After healing, the restoration (the visible portion of the implant) is placed so you can eat comfortably and smile with confidence.

If you would like to learn more about the dental implant process at Lake Forest Oral Surgery, please call our office at (949) 203-3177. We will be happy to arrange a consultation with Dr. Um to review your needs and see if you are a good candidate for dental implants.

A dental implant is a small titanium post that’s surgically implanted into the jaw bone to replace the root portion of a lost tooth. It resolves the esthetic problem of a missing tooth. Once we restore the implant with a crown, it performs and looks just like a natural tooth.

Titanium is biocompatible, meaning that the body readily accepts the material, and allows the implant post to fully integrate with the jaw bone and tissue. Once healing is complete, the implant actually becomes part of the structure of your jaw.

This provides a measure of stability that is not found with other tooth replacement options. When the implant has fully integrated, Dr. Um completes the process by creating a dental crown, bridge, or denture that is affixed to the implant. 

Specific factors affect the success of your dental implant. One is that there must be enough bone in the jaw for successful placement of the implant. In some cases, it may be necessary to perform a procedure like bone graft surgery or a sinus lift to get the best results.

If you and your dentist have decided that a dental implant is a good option for you, please call Lake Forest Oral Surgery so we can arrange a consultation.


At Lake Forest Oral Surgery, we are pleased to offer a wide range of sedation techniques that allow us to provide you with the comfort and relaxation you need to undergo certain procedures. During your initial consultation, Dr. Um will make recommendations as to the best method for you.

For simple surgeries and implant placement, we typically combine a local anesthetic with nitrous oxide sedation. Nitrous won’t put you to sleep, but it will help calm you, so you’re not as aware of your surroundings.

Other procedures require IV sedation including bone grafting or removal of impacted teeth. As the name implies, IV sedation is injected intravenously into your bloodstream, making the effects immediate.

You will achieve a deep level of comfort, but you will be semi-awake and able to respond to your surgical team. You won’t feel any pain, and you probably won’t remember anything about what took place before or immediately after your procedure.

Our team will monitor you during a brief recovery period at our office. Since the effects of IV sedation linger for several hours, you will require an escort to drive you to and from your appointment.

Please call Lake Forest Oral Surgery if you have questions about the best type of sedation for your procedure. 

Bone Grafting & Sinus Lifts

An implant is surgically placed in your jaw, so it requires sufficient support. But gum disease, trauma (teeth grinding, car accident) and loss of the tooth can lead to deterioration of the bone. 

If you are considering dental implants, bone loss can be a problem. The success of an implant depends mainly on the quality and quantity of bone in your jaw. But lack of sufficient bone density can make successful implant placement impossible. 

You don't have to give up hope if your dentist has told you that you can't get an implant. Fortunately, bone grafting can build the bone in the area so it will eventually be able to support the implant. 

If you don't have enough bone for a dental implant, Dr. Um takes bone from another part of your body or utilizes tissue engineering and stem cell technology to create enough bone mass and successfully support your implant.

For your complete comfort, bone grafting at Lake Forest Oral Surgery will be completed under IV sedation. You will remain conscious and able to respond to your doctor but will have little or no memory of the procedure. The effects of sedation stay in your system for several hours, so you will need a driver to get you to and from your appointment.

If you have been told you're not a candidate for an implant because of bone loss, please call Lake Forest Oral Surgery to arrange an evaluation with Dr. Um.
