The company, which was founded in 1989, currently operates across Spain and Italy but plans to extend its reach to Poland with the new capital.
Vitaldent runs a franchise and coroporately-owned clinic model and has a network of prosthetic laboratories for treatment of structural tooth problems.
It has forecast its EBITDA for the 2013 financial year to be €33m, up six per cent on the previous 12 months.
In October venture investor Tenaya Capital helped dental services marketplace Brighter raise $15m by leading a Series C financing round for the business.
Existing investors Mayfield Fund and Benchmark also took part in the financing round, which Brighter said would be used to expand it into new markets across the US.
