Found my forever hygienist
I recently saw Tamsin for dental hygiene, and she was outstanding. She is professional, gentle, and explains everything clearly. Tamsin is thorough in her work but also very considerate, making sure I was comfortable throughout the appointment. My teeth have never felt cleaner, and I left with helpful advice that was easy to follow. She combines skill with a really warm and friendly manner. I’d highly recommend her to anyone looking for excellent dental care.
