"Tiruppugal pada pada vaai manakkum m m m" ..... appo enda pallu velakkra... adaye padu, kannu, mooku, kaadu varaikum ellam manakkum. Avan Avan computer la pallu velakkuran... neenga innum tirupugalaye paditu irunga da"

The dialogue describes teeth shining so bright that they illuminate everything - face, eyes, nose, and even the forest (kaadu). The comparison to 'Sooriyan' (Sun) is the direct clue - the character's teeth shine like the sun. This is a classic Tamil cinema exaggeration where a character's dazzling smile is compared to the sun's brilliance.
