Periodontist In Seattle, WA
The Periodontal Difference
Most dentists refer complex gum cases to periodontics specialists. There’s a reason why.
Dr. Sweeney and Dr. Spoor completed three additional years beyond dentistry school, focusing exclusively on treating gum disease and placing dental implants. This specialized training means our practice handles challenging cases daily – from severe bone loss to complex implant procedures. While general dentistry offers routine cleanings, we provide the advanced periodontal care your gums actually need.
“Periodontal health drives dental success.” This philosophy drives our comprehensive approach. Healthy gums create the foundation that makes all dental work more successful – from simple fillings to complex implant cases. Even Invisalign treatments work better with healthy periodontal support.
Patients deserve a periodontist’s expertise when facing gum disease. Our Seattle office combines cutting-edge technology with proven techniques to treat conditions others can’t. General dentists throughout Seattle trust us with their complex surgical cases, knowing we’ll provide seamless care coordination.

Our Expertise
Comprehensive periodontal care under one roof
From early gingivitis to advanced periodontitis, we stop disease progression and restore healthy gums. Our approach includes deep cleanings through scaling and root planing, laser therapy, and regenerative procedures that rebuild lost bone.
FDA-cleared laser therapy for gum disease without cutting or sutures. As an established LANAP provider, we offer this minimally invasive alternative to traditional gum surgery with faster healing and less discomfort.
As periodontics specialists, we understand both surgical placement and long-term gum health around implants. Unlike practices that only place implants, we provide complete implant care – both surgical placement AND final restoration (crowns/bridges). No referrals between specialists needed.
We specialize in comprehensive cases other practices can’t handle, including All-on-X full-arch procedures and complete mouth rehabilitation.
Exposed roots causing sensitivity? Our gum grafting procedures restore your natural gum line while protecting vulnerable tooth surfaces. Modern techniques mean minimal discomfort and faster healing for patients.
Digital imaging and 3D scans reveal what routine exams miss. We catch problems early when treatment is simpler and more affordable.
