Preventive Care Services:

At your first visit, we will complete a detailed examination of your teeth, gums, and mouth in general. Our preventive services can include:

  • Regular checkups and cleanings
  • Athletic mouth guards
  • Sealants
  • Fluoride treatments

You may have worn, chipped teeth. That can all be due to bruxism, or teeth grinding/clenching. You may be suffering from continuous headaches that could be related to that as well.

Dr. Lee and Dr. Ku have extensive knowledge in those issues, and can determine the best treatment for you such as nightguards and anterior bite planes. Such worn and chipped teeth may also be affected by acidic drinks and foods that we ingest daily. Dr. Lee and Dr. Ku can determine if and what restorative procedures could be ideal for you.

Restorative Services:

  • Implant supported crowns, bridges, and partial dentures.
  • Porcelain crowns
  • Veneers

Gum Diseases / Periodontal Treatment:

Gum disease is a common problem in our country. When too much hardened plaque accumulates around the gum line of teeth, it can be very harmful as it can cause inflammation and bleeding of the gums, damaging the surrounding fragile ligaments that connect the teeth to the gums and bone.
We offer a non-surgical treatment called root planing and curettage that can help you maintain your oral health. In many instances we also use a diode laser to help sterilize the deeper pockets in conjunction with antibacterial medicaments.

Aesthetic Procedures:
  • Tooth-colored fillings
  • Tooth-colored conservative inlays and onlays
  • All-porcelain crowns and veneers
  • Bonding
  • Invisible braces with ClearCorrect TM


Amazing no-sensitivity in-office laser whitening with Sapphire TM (from the makers of Lumineers).
