Thiruvadanthai is located on the Chennai - Kovalam road on the way to Mahabalipuram.

The Moolavar is Lakshmi Varaha Perumal seen in the standing posture facing East.  The utsavar is Nithyakalyana Perumal, seen with a pottu in his jaw.  There are sannadhis for Andal, Sri Ranganathar, Sri Ranganayagi.  The Lord merged the 360 daughters of Kaalava maharishi into one maiden & seated her on his lap. It is considered that he married the 360 maidens one day after the other, & hence he is seen in Kalyana kolam everyday, hence the name Nithya Kalyana Perumal.  Since he is holding the Devi on his left (Idam in Tamil - left), the place is known as Thiru Ida Endhai.
