Dr. Alexandra Glants

Dr Glants’s Dental Philosophy: “Often times, treating a particular problem in isolation is warranted, but I strive to assess the patient’s whole health and tailor a treatment plan to fit their goals and lifestyle. Creating proper teeth alignment is the best preventive treatment that will ensure a healthy bite and tooth longevity along with increased self esteem.”
