General Business License

Maine does not have a statewide general business license. Businesses must register their entity with the Maine Secretary of State and register with the Maine Revenue Services for sales tax purposes.

Common Mistakes to Avoid

1
Starting insurance credentialing after signing the lease — credentialing takes 3-6 months and delays revenue
2
Buying all new equipment instead of quality refurbished equipment — save 30-50% without sacrificing function
3
Underestimating patient acquisition costs in a new market — budget $50,000-$100,000 for first-year marketing
4
Not hiring an experienced dental practice consultant before opening
5
Setting production goals too low — a 4-operatory practice should target $1.2M-$2M annual production

Next Steps to Launch Your Dental Practice

1
Obtain your Maine dental license from the Maine Board of Dental Examiners before opening
2
Register your Dental Practice as a professional LLC or PLLC with the Maine Secretary of State ($175 filing fee)
3
Obtain DEA registration for controlled substance prescriptions (anesthetics, pain management) used in your practice
4
Credentialing with Delta Dental, Cigna, Aetna, and major dental insurance networks (3–6 month process)
5
Get dental malpractice insurance and general liability coverage ($5,000–$15,000/year)
6
Finance dental equipment: dental chairs, digital X-ray sensors, panoramic X-ray unit, CAD/CAM, and autoclave sterilizer
7
Set up HIPAA-compliant dental practice management software (Dentrix, Eaglesoft, or similar) with patient portal
8
Schedule a pre-opening compliance inspection and confirm your Maine OSHA dental office standards are met

Frequently Asked Questions

Opening a dental practice costs $250,000 to $1,000,000. A 2-3 operatory starter practice can open for $250,000-$400,000 using some refurbished equipment. A modern 4-6 operatory practice with all new technology typically costs $500,000-$800,000. A large group practice can exceed $1,000,000.

Buying an established practice ($300,000-$1,000,000) provides immediate patient revenue, existing staff, and proven systems. Starting from scratch (de novo) costs similar but takes 3-5 years to build comparable revenue. Most new graduates are better served buying an existing practice if they can negotiate well.

Dental practice owners earn $200,000-$400,000+ annually in take-home compensation, including salary and practice profits. A well-run practice producing $800,000/year might pay the owner $250,000-$350,000. Specialists (orthodontists, oral surgeons) earn more — $400,000-$700,000+ in established practices.

Insurance credentialing takes 60-180 days per insurer. Apply to all major payers (Delta Dental, Cigna, Aetna, United Healthcare) at least 6 months before opening. Not being credentialed means patients with insurance cannot use their benefits at your office, severely limiting new patient flow.

Essential equipment includes: dental chairs with delivery units ($8,000-$20,000 each), digital X-ray sensors ($4,000-$10,000 each), panoramic X-ray machine ($15,000-$40,000), autoclave/sterilization center ($3,000-$8,000), dental compressor ($2,000-$6,000), and operatory lighting. Budget $25,000-$60,000 per operatory fully equipped.
