Our practice, Chelmsford Dental Specialists Group, was founded in 1983 by Dr. Michael Sargent under the name Michael Sargent Dentistry. Today, we provide comprehensive care with a team that includes three general dentists (Dr. Mei-Yee Chan, Dr. Yousef Sidki, and Dr. William Negreiros) and a prosthodontist (Dr. Mario Gatti). We want our patients to be able to participate in their own care, which is why we put so much emphasis on education. We know that our patients have a wide variety of oral health needs; as such, we provide a wide range of services, from dental crowns for repairing natural teeth to dental implants for filling in the gaps in your smile to teeth whitening for brightening your grin. Our dentists in Chelmsford are looking forward to getting to know you better and forming a trust-based relationship with you. To schedule a consultation with our team, pick up the phone and reach out to us today!
