Why Leander patients choose Siena Dental
Referrals are the exception
Implants, root canals, aligners, and full-mouth restorations happen here, so your records and your dentist stay the same.
You hear every option first
Your dentist shows you what we found and walks through each option. We never push treatment you don’t need.
Three languages on our team
Our team speaks English, Spanish, and Farsi.
Planned in 3D
CBCT scans and 3D impressions, part of our dental technology, give us better-fitting crowns and precise implant placement.
Comfort on request
TV shows, wireless headphones, blankets, and pillows. Sedation is here when a blanket isn’t enough.

“This is a new dental office in the Leander community that was on the list of offices that the VA approved. My visit was very pleasant and thorough. The hygienist and dentist were nice and knowledgeable while treating me. The staff greeted me with warm, welcoming vibes. I look forward to my follow-up visit.”
