Below are top SEO and PPC agencies (U.S.-focused) that specialize in — or have strong track records with — dental practices. I’ve included a short note about what each is known for to help you pick the right fit (local/dental specialty vs. multi-location/enterprise). Sources cited for the most important claims are listed after the entries.

How to pick among them (short)

• Solo practice/local dentist: choose a dental-specialist boutique that limits clients per territory (ex: Rosemont, DDS Rank, some boutique firms) to avoid local conflicts. (ddsrank.com)
• Multi-location or DSO: prioritize agencies with enterprise/local-at-scale experience (Cardinal, WebFX, Scorpion, Amplify360). (growfusely.com)
• If you want full-stack (site + SEO + PPC + reputation + intake): consider PatientPop, Scorpion, WebFX or Wonderist. (afiafix.com)
• Procedure-heavy practices (implants, ortho, cosmetic): look for agencies with specific case studies for those procedures and paid-media expertise (specialists like WEO Media, LassoMD, Dental PPC boutiques). (blog.applabx.com)

• Prepare screening questions and a comparison spreadsheet (cost ranges, services, contract length, exclusivity, expected KPIs) you can use when you contact agencies.
