The child suddenly had a toothache at night, and we were in a panic. Most clinics in Boston are either closed or do not accept children without an appointment. Luckily, we found Emergency Dentist Boston - they have pediatric dentists, and they accept even on weekends without queues.
They were very gentle with the child, explained everything, took an X-ray and temporarily relieved the pain. I really recommend that parents keep this clinic “bookmarked” - it can be useful at a critical moment.
