Services
Composite Fillings
Our composite fillings restore decayed teeth with durable, natural-looking resin that matches your tooth color. This mercury-free solution bonds directly to the tooth structure, preserving more natural enamel while providing long-lasting protection against further decay. Patients appreciate the aesthetic benefits and reduced sensitivity compared to traditional metal fillings.
Dental Implants
We offer permanent tooth replacement solutions through dental implants that mimic natural tooth roots. Using titanium posts surgically placed in the jawbone, we create stable foundations for crowns or dentures. Our guided implant placement technology ensures precise positioning for optimal function and aesthetics, with success rates exceeding industry averages.
Sleep Apnea Treatment
Our customized oral appliances treat obstructive sleep apnea by maintaining proper airway positioning during sleep. Dr. Hsu's diplomate status in dental sleep medicine ensures expert diagnosis and appliance design that improves breathing patterns without the discomfort of CPAP machines, with follow-up adjustments for optimal effectiveness.
Root Canal Therapy
Our advanced root canal procedures eliminate tooth pain caused by infected pulp using specialized techniques that preserve natural tooth structure. With digital imaging and micro-instrumentation, we thoroughly clean root canals while minimizing discomfort, often saving teeth that would otherwise require extraction with a 95% success rate.
Orthodontics
We provide traditional and clear aligner orthodontic treatments to correct bite issues and improve smiles. Our board-certified specialists create personalized treatment plans using digital scanning technology for precise tooth movement, addressing both aesthetic concerns and functional dental health improvements.
