Dr. Heidi Sun helps a young patient with dental hygiene.

Gentle and Caring Dentistry

Sun Dental has been providing its patients with personal and friendly service for over 37 years. Dr. Heidi Sun has extensive training in advanced cosmetic and restorative dental procedures. Using the latest technology Dr. Heidi will confidently handle any and all of your dental needs.

We consider all of our patients a part of our family. With proper dental care you can keep your teeth healthy for life – and that’s what we like to help our patients do.

We can handle all of your dental needs

In addition to regular dental checkups and cleanings, Sun Dental provides a full range of cosmetic and restorative dental procedures. We keep up with the latest techniques and innovations in order to better service you. This includes, for instance, the use of Perio Protect non-surgical treatment to eliminate gum disease and help you to preserve your teeth. Sun Dental is the only Certified Perio Protect provider in Lake County.

But even more importantly, we work to keep our services affordable so that you don’t have to settle for poor substitutes, such as pulling a tooth instead of having it fully repaired and restored because it is too expensive.

Preventive Dentistry: Cleaning & Checkups

We provide expert teeth cleanings, checkups and gum care to keep your teeth healthy and strong.

Dental Restoration

Dr. Heidi is very experienced in the restoration of broken, crooked, damaged or missing teeth. She can help you review your options, including dental implants, crowns, bridges,veneers or dentures.

Cosmetic Dentistry

Dr. Heidi can provide you with many affordable options to create a beautiful smile, including porcelain veneers, lumineers, dental bonding, crowns, inlays and onlays. Your treatment plan will be customized to fit your needs and your budget.

We offer a free cosmetic consultation to see which cosmetic option will work best for you.

One-Visit Crowns

With the use of computer-assisted design and manufacturing equipment here in our office, we can provide you with perfectly engineered crowns, inlays and onlays in a single visit. Learn more.

Mature Adult Dentistry (Senior Dentistry)

Oral and dental treatment as you get older require a more specialized care and understanding. We help you keep your natural teeth and where needed restore or create you an attractive, rejuvenating smile. Learn more.

Dental Implants

Are you missing teeth or do you need extractions? We provide quality, durable natural-looking dental implant restorations. Sometimes it is difficult to know which solution is best for your teeth and budget. Dr. Heidi provides a no-charge consultation. Learn more.

Porcelain Veneers

Dr. Heidi can transform your smile with porcelain veneers – thin facings that cover individual teeth to change their shape, color and alignment. Both traditional porcelain veneers and ultra-thin "prepless" Lumineers are available. Learn more.


We make accurately fitting, natural-looking and comfortable dentures that are placed in such a way as to deter bone loss. Dr. Heidi often recommends implants or mini-implants to strengthen the dentures, which can be placed at our office.

Mini Implants

Your dentures can be supported by "mini" dental implants, in a single office visit, with excellent stability and no slippage.

Porcelain Crowns

Our crowns are made from high quality porcelain and filler material. We make sure they look natural and fit the rest of your smile. With the new E4D technology, you can have your permanent crown in a single, short visit. Learn more.

Inlays and Onlays

Inlays and onlays are restorations that are fitted to a cavity or broken area in a tooth and bonded in place. For larger cavities they are stronger and more durable than a regular filling. They save more tooth structure than a crown.

Clear Braces

With ClearCorrect removable braces, straightening your teeth is easy. No metal wires or appliances, just clear aligners that move your teeth into place. Learn more.

Gum Disease Treatment

As a certified Perio Protect provider, we treat all stages of gum disease. Click here to learn more.

TMJ Analysis

If you are suffering from any of these symptoms, we can help:

  • Sore jaw muscles and joints especially right after waking up in the morning.
  • Clicking and/or popping sounds in the jaw joint when opening or closing the mouth.
  • Chewing surfaces are flat and/or worn down through the tooth enamel. This exposes the second, soft and yellow layer of the tooth.
  • Incisal edges of teeth are worn and sensitive to cold or tooth brushing.
  • Loose or broken teeth, crowns or bridges for no particularly obvious reason.
  • Generalized feeling of tooth pain.
  • Grinding, clenching or bruxing.

All of these symptoms can be caused by Temporomandibular Joint Disorder or TMJ Syndrome. This is an inflammation of the Temporomandibular Joint, which connects the lower jaw to the skull. Dysfunction of this joint can cause significant pain and damage. Dr. Heidi is specially trained in TMJ analysis and treatment, and can relieve your pain and other symptoms. Learn more.


Dr. Heidi provides custom bridges to close gaps in teeth.

Dental Bonding

Dental bonding can be an affordable and quick solution for making cosmetic improvements by changing the color of your teeth or reshaping your teeth. Learn more.

Root Canals

Our root canals are fast and comfortable thanks to the use of motorized rotary instruments and local anesthetic.


We do routine extractions, including wisdom teeth.

Oral Sedation Dentistry

This relaxing method of treatment is perfect for those afraid to go to the dentist, helping you to relax so that Dr. Heidi can complete your treatment easily and safely. With sedation dentistry, you'll relax completely, and accomplish more in a single dental visit than you ever thought possible.
