Child neglect?

Is it neglect?

I know a family who has two (now teens) who haven't seen a dentist in 6-8 years! The now 18 yr old daughter (still living at the home) has impacted wisdom teeth, cavities, and frequent infections. She has troubles drinking cold things from the pain. The other child is 17 and is starting to get cavities too.

The parents have had several bancrupcys and claim they have no dental insurance. Yet, haven't looked for resources or asked for assistance. Is it neglect? The last time the oldest child saw a dentist was when she was 10-12 yrs old and the youngest child was 8-10...
