Dr. William Machida

Dentistry runs in my family, with both my parents practicing as dentists in Japan. Growing up, I saw how dentistry combined science, art, and meaningful patient relationships, which inspired my path. After initially pursuing environmental research, I realised I missed the hands-on craftsmanship of working directly with people, so I returned to dentistry—a field where all these passions converge. 

What I enjoy most about being a dentist is the opportunity to connect with each patient, hear their unique life stories, and collaborate on solutions that improve both their oral health and confidence. Whether I’m planning comprehensive care, performing precise surgical procedures, or using advanced digital techniques, my focus is always on delivering results that last and benefit the patient’s overall health. 

Nothing is more rewarding than seeing patients flossing regularly and maintaining healthy habits, knowing these efforts minimise the need for further treatment. Working at No Gaps Dental for the past seven years has been an enriching experience, surrounded by a team that shares my dedication to patient care and collaboration. 

How I stay healthy and happy 
I stay active with rock climbing and bushwalking, enjoying Sydney’s natural beauty while staying fit. Reading helps me gain fresh perspectives, and travelling allows me to connect with diverse cultures, broadening my understanding of people and their values. Spending time with friends, family, and nature keeps me grounded and fulfilled.

How I maintain healthy teeth and gums 
I make flossing and brushing a consistent daily habit, no matter the circumstances, and combine it with regular check-ups to ensure long-term oral health.

Essential tip to keep your teeth healthy 
Floss every day and schedule regular six-month check-ups—preventative care keeps small issues from becoming big problems.
