Final answer:
Facilities must assist residents with obtaining routine and emergency dental care to address urgent issues that can lead to severe pain or infections.
Step-by-step explanation:
The question asks which type of dental care a facility must assist residents with obtaining, in addition to routine care. The correct answer is b) emergency dental care. It is essential for a facility to have the capability to facilitate both routine and emergency dental services for its residents. This is not only a matter of health and hygiene but also pertains to urgent care that prevents long-term damage and alleviates severe pain or risk of infection that can arise from dental issues. While preventative, orthodontic, and surgical dental care are important, they are not as immediately critical as emergency interventions.
