Comprehensive Cleanings & Exams

Dental insurance forms | Dentist Elgin ILInsurance is an important consideration for most people, and although we are out-of-network for all insurances, we will accept all insurance claims and handle the billing for you. Any unpaid balance is your responsibility, and we’ll be happy to bill you, or you can pay the estimated portion on the day of service.

We're also pleased to offer a Dental Savings Plan to make the cost of your treatment more affordable. Please call for more details.


Crowns & Bridges

Dental Crown | Dentist Elgin ILFor the best possible long-term result, a dental crown may be your best option for restoring the tooth. As the old filling starts to deteriorate, the tooth weakens. If we don’t do something to strengthen it, the tooth may become more damaged and may even fracture.

Crowns placed at Won Sung, DDS, are durable and beautiful. We’ll create your new crown out of a ceramic material that looks similar to your natural dental enamel. The result is a restoration that blends in perfectly with surrounding teeth.

The Dental Crown Process

The process of placing a crown usually requires two to three visits. During your first visit, we’ll start by preparing your tooth so that the new crown will fit perfectly, right down to the gum line. Next, we’ll take impressions of the prepared tooth. The impressions are used to create a model that’s sent to our dental lab where your new crown is constructed. Using the same impression, we also create a temporary crown.

About two weeks later, you’ll return to our office for your new crown. Dr. Sung will check the crown carefully for fit, adjusting it as necessary. Finally, the crown will be polished and cemented securely to your natural tooth.

If you’re worried about fillings that are failing, please call our Elgin dental office. We’ll be happy to set up a consultation so we can make appropriate recommendations.

If you experience any symptoms such as cold and hot sensitivity, pain upon biting and chewing, or constant aching and throbbing, pick up the phone and call Dr. Sung’s office right away. Even if you don’t experience any pain, when in doubt, please call Dr. Sung’s office.   

Man holding jaw in pain | Elgin IL DentistA broken tooth normally requires a crown or a large filling or in more serious cases, an endodontic treatment (Root Canal Therapy) or a tooth extraction. There is no need to panic. Dr. Sung is highly skilled in treating such cases. Until you see Dr. Sung, try not to aggravate the condition by avoiding chewing on the affected side. Also avoid anything that’s too hot and cold, acidic and sweet. Do not delay to get an appointment. A once salvageable tooth may not be saved if too much time has passed.         

Our office is closed to non-emergency dental care to curb the spread of COVID-19 and alleviate the burden on hospital and emergency departments.

Root canal diagram | Dentist Elgin ILIt’s common to experience some sensitivity to cold, hot, sweet, and pressure from chewing. When the sensitivity becomes more intense (like sharp pain), lingering, and continuous, it means the nerve in your tooth is very inflamed and infected.

This is called irreversible pulpitis, and we need to perform a root canal to eliminate the pain. Without treatment, the pain will continue and increase, and we may need to remove the tooth to provide relief.

When the pulp inside the tooth is infected, a root canal is necessary. During the procedure, Dr. Sung gently clears away any damaged tissue, then carefully cleans and seals the tooth. We may just need to fill the tooth after root canal treatment, but in most cases, we’ll recommend a dental crown to protect and strengthen the tooth.

Comfortable Root Canals

We make every effort to keep you comfortable during your root canal. Aside from our gentle approach, we offer mild nitrous oxide sedation to help keep you calm during your procedure. Nitrous oxide doesn’t produce any lingering after-effects, so you’ll be able to resume your normal activities, and you won’t need a designated driver.

If you’re in pain or suspect you may need a root canal, please contact our Elgin office as soon as possible. The sooner we get you in for treatment, the sooner we can help you get relief.

Oral Surgery

Woman sitting in dental chair | Elgin IL DentistWe make every effort to provide injections that are as pain-free and comfortable as possible. Dr. Sung has a very gentle touch and years of experience in delivering injections slowly and carefully to minimize any pressure or discomfort.

One method we use for easing your injections involves a small but effective device called the Vibra-Jet. The principle behind the device is that the syringe vibrates very slightly, which stimulates nerve endings and blocks the pain message to the brain.

Comfortable Dentistry

Our team is highly sensitive to the fact that many of our patients are apprehensive about injections. We’ll do everything we can to put you at ease. When you feel comfortable with us, you’ll be able to approach your appointment knowing that you’re being cared for by familiar people who understand your concerns.

If you have any concerns about an injection before your procedure, please don’t hesitate to tell us. We know very few people who actually enjoy getting shots, so you’re certainly not alone in your fearful feelings. If something’s bothering you, we want to know so that we can tailor your treatment to fit your specific needs.

Please give our Elgin dental office a call if you’d like to learn more about our comfortable injections. 

TMJ Treatment

Older woman holding jaw in pain | Dentist Elgin ILBruxism, or teeth grinding, is an involuntary activity that is controlled by your brain. Teeth grinding most often occurs during sleep, so even if you’re grinding your teeth during the night, it may not be noticeable to either one of you. Also, not everyone who grinds their teeth experiences painful symptoms, so you can still grind your teeth and not feel any discomfort.

Detecting Teeth Grinding

It’s easy for us to detect signs of teeth grinding during one of your routine dental exams. Dr. Sung will check your dentition (different characteristics of your teeth) and look for chips, minor cracks, or any signs of unusual wear on the chewing surfaces of your teeth. Teeth grinding may be caused by excess stress, a misaligned dental bite or even temporomandibular joint disorder (TMD).

Treatment for Teeth Grinding

A thorough exam with Dr. Sung is the best way to evaluate your situation and pinpoint the underlying cause for your grinding and clenching. We will work with you to diagnose the problem and recommend the most appropriate, cost-effective, and conservative treatment. In many cases, we can customize a simple appliance called an occlusal splint that will prevent your teeth from coming into contact with each other during sleep.

Please give us a call if you think you may be grinding your teeth. We’ll be happy to arrange a consultation with Dr. Sung so you can discuss your concerns.
