Shortly before the 2005 Turkish Grand Prix, Monteiro suffered a toothache that was severe enough to prevent him taking part in the race. However, his team principal Colin Kolles, a qualified dentist, performed emergency root canal surgery and Monteiro was cleared to race. He finished 15th following a collision with Juan Pablo Montoya, which resulted in the Colombian running wide on the penultimate lap and losing second place to Fernando Alonso, thus preventing Montoya's McLaren team scoring its first 1–2 finish since the 2000 Austrian Grand Prix.
