Single Dental Implants

  • Dental implants are a life-changing way to rehabilitate an incomplete smile. Made of durable, high-quality materials, dental implants can seamlessly fill in the gaps left by missing or decayed teeth. They’re customized to fit you and complement your existing teeth.


  • This protocol enables us to provide minimally invasive gum disease treatment. That means no scalpels or sutures are needed. Instead, Dr. O’Neill uses high-precision laser technology to remove unhealthy tissue and eliminate bacteria. This makes healing smoother and faster too.

Full Arch Treatment

  • You can have a full smile of beautiful, healthy teeth again, even if you’ve already lost most or all of your teeth to decay. Our periodontist, Dr. O’Neill, can replace these with permanent ones that look, feel, and perform just like the real ones. What’s more, he can achieve this in a single visit!
