Hello! You add a lot of new keys with a prefix service.
service:bridge = bridge
service:crown = crown
service:dental_sealant = dental sealant
service:implant = dental implant
service:orthodontics = clear aligners
service:prosthetics = denture
service:retainer_hawley = Hawley retainer
service:retainer_metal = Metal retainer
service:scaling = scaling
service:veneer = veneer
service:whitening = teeth whitening

This is usually followed by information about what type of service is involved (in this case, dentist) and then a yes/no statement. So instead of
service:bridge = bridge
service:crown = crown
it would be more like
service:dentist:bridge = yes
service:dentist:crown = yes
