Dentists choosing Lean FIRE face the same temptation as physicians: after years of dental school poverty and residency, the pressure to "finally enjoy" the income is intense. But a dentist who maintains a $30,000/year personal spending level on $220,000 income can reach $750,000 in just 8–10 years post-debt-payoff — achieving Lean FIRE at 44–48. The decision to choose Lean FIRE over Fat FIRE represents a 10–15 year time difference in exit from clinical practice.
Defined benefit pension plans for self-employed dentists are the most powerful Lean FIRE accelerator available. A dentist owning their practice at 40 can contribute $100,000–$200,000+/year to a defined benefit plan, sheltering massive income from taxes while building retirement wealth at extraordinary speed. Even modest defined benefit contributions ($80,000/year) can build $750K in 6–7 years from practice start.
The practice sale at Lean FIRE: a dentist retiring at 46 with a well-run practice grossing $600,000/year receives $400,000–$500,000 in sale proceeds. If personal investment portfolio is $400,000 at that point, total liquid wealth is $800,000–$900,000 — above the $750K Lean FIRE threshold. Many dentists achieve Lean FIRE through the combination of reduced personal savings during accumulation and the practice sale providing the gap-filling lump sum.
