Richard D. Allen DDS, PC

Most dental offices handle routine cleanings and fillings, but when a tooth’s inner layers need attention, a specialist becomes essential. Richard D. Allen DDS, PC focuses on endodontics, the branch of dentistry dedicated to diagnosing and treating issues inside the tooth—think root canals, cracked teeth, or infections that go beyond the surface. Unlike general dentists, endodontists like this practice zero in on preserving natural teeth, often saving them from extraction when damage runs deep. The office sits at 1704 S Cleveland Ave Unit 6 in Sioux Falls, tucked into a stretch of the city where professional services and light commercial spaces blend with residential pockets.

Root canal therapy might be the most recognized procedure here, but the practice also addresses traumatic dental injuries, retreatment of prior root canals, and complex cases where pain lingers without obvious cause. While endodontics isn’t the kind of care people seek out casually, it’s the kind they’re relieved to find when a persistent toothache or a dentist’s referral sends them searching. For questions or to confirm details, the phone line is (605) 221-0218—no frills, just the direct route to someone who can explain what happens when a tooth’s pulp or nerves are under siege.

The building itself is unassuming, a practical stop rather than a landmark, but that’s typical for specialty practices where the work happens behind the scenes—literally. Sioux Falls’ south side offers easy access from nearby neighborhoods and the interstate, making it a convenient midpoint for patients coming from across the city. To pinpoint the location or plan a visit, the map lays out the route without detours. No embellishments needed; the details speak for themselves.
