Summary
Royal Smiles Dental Clinic is a Kenyan dental group co-founded by micro-endodontist Dr. Simiyu Benjamin Nyongesa and dental surgeon Dr. Gladys Maina, with branches listed in Ruaka, Machakos and Nakuru and additional registered branches in Nairobi (including Garden City Business Park). Services cover emergency care, cosmetic dentistry and orthodontics, pediatric dentistry, preventive care and restorative treatments. The website names its two lead clinicians with credentials but does not publish a price list, and street-level addresses are easier to find in third-party directories than on the site itself.
Multi-branch group; website currently lists Machakos, Nakuru and Ruaka branches, while the Kenya Master Health Facility Registry and directories also list a Garden City (Thika Rd, Nairobi) branch at Garden City Business Park, 1st Floor, Block A, Suite A103 (approx. -1.2352249, 36.8749417). The site's /contact URL returned HTTP 404 on 2026-07-04. Directory listing states Jubilee insurance and company schemes accepted.
