For people with allergies or sensitivities, visiting the dentist can mean exposure, often unwittingly, to problem substances. I’ve been practicing dentistry since 1978, providing cosmetic, general and reconstructive dentistry in an allergy-friendly, state-of-the-art facility in downtown Chicago. My interest in allergies and sensitivities is both professional and personal. My wife has celiac disease. Before she was diagnosed, she was frequently quite ill with headaches, gastrointestinal distress and general malaise. It wasn’t unusual for her to be bedridden for days at a time.
