About Ontario Smiles Dentistry and Orthodontics

Dental care often gets pushed to the back burner until something aches, but regular checkups and orthodontic evaluations can prevent bigger issues down the road. In Ontario’s eastside commercial corridor, a practice combines general dentistry with orthodontics under one roof—no need to juggle referrals for braces or aligners. Routine cleanings, fillings, and teeth straightening share space in the same office, which sits just off the 60 Freeway near East 4th Street. Reviews paint a consistent picture: the Google listing shows 4.6 stars from 395 ratings, a sample size large enough to reflect real patient experiences over time.

Orthodontic consultations and cavity treatments don’t usually share an address, but this setup skips the back-and-forth for families coordinating care. Questions about payment options or scheduling a first visit? The front desk fields calls at (909) 378-9156 during business hours. For those mapping out the trip, the office is pinpointed near the intersection of Archibald Avenue—plug the address into directions here to avoid circling the strip mall. No frills, just the basics: a dental practice that handles both straightening teeth and keeping them healthy.
