Hygiene in the Middle Ages was generally poor. People did not have access to modern sanitation and hygiene practices, leading to widespread filth and disease.

The lack of understanding of germs and bacteria also contributed to the poor hygiene practices of the time. Overall, the Middle Ages were a time of limited cleanliness and hygiene. **

Good oral hygiene involves maintaining a routine of daily practices to keep your mouth clean and healthy. This includes brushing your teeth at least twice a day with fluoride toothpaste, flossing daily to remove plaque and food particles between teeth, and using mouthwash to kill bacteria. Regular dental check-ups and cleanings are also important to prevent and detect any oral health issues early on. Additionally, avoiding tobacco products and maintaining a balanced diet can contribute to good oral hygiene. **

Private health insurance typically does not cover teeth whitening procedures, as they are considered to be cosmetic treatments rather than medically necessary.

The second middle name may not be on the health insurance card because it is not always necessary for identification purposes.

Including the second middle name may not be required for the card to serve its purpose. Additionally, space constraints on the card may also be a factor in excluding the second middle name. **

Based on the information provided, it is not possible to determine if the friend has poor oral hygiene. The fact that the friend has not visited a dentist in several years could indicate poor oral hygiene, but it could also be due to other reasons such as fear of the dentist, financial constraints, or simply not feeling the need to go. Without more information, it would be unfair to make assumptions about the friend's oral hygiene. **
