Commentary
The substitution of दत् for दन्त is optional in a बहुव्रीहि समास when it is preceded by a word ending in 1. अग्र or by 2. शुद्ध 3. शुभ्र and 4. वराह।
The word "optionally" is understood here also. Thus कुड्मलाग्रदन्, or कुड्मलाग्रदन्तः, so also शुद्धदन्तः or शुद्धदन्, शुभ्रदन्तः or शुभ्रदन्, वृषदन्तः or वृषदन्, वराहदन्तः or वराहदन् ॥
The च of the sutra indicates that the substitution optionally takes place in other cases not enumerated : as अहिदन्तः or अहिदन्, मूषिकदन् or मूषिकदन्तः, गर्दभदन्तः or गर्दभदन्, शिखरदन्तः or शिखरदन् ॥
