Final answer:
Anglo-Saxons likely used natural materials like twigs, similar to ancient chew sticks, for oral hygiene, as specific historical records on their exact methods are sparse, but the need for such practices is inferred from related studies on dental health.
Step-by-step explanation:
The Anglo-Saxons did not have access to modern dental care, but they still had methods for oral hygiene. Though specific records of what the Anglo-Saxons used to brush or polish their teeth are sparse, we know that ancient peoples commonly used a chew stick, which is a twig with a frayed end, to clean their teeth. Similar to the bristled toothbrush that spread across Europe much later, these early oral care tools helped to remove debris and polish teeth.
Considering the broader context of Anglo-Saxon tools and the study of dental and skeletal remains, it may be inferred that natural materials such as twigs or leaves could have been utilized for teeth polishing. Ebeling and Rowan's study revealed that with the rise of carbohydrate consumption during the Neolithic Period, there was an increase in dental decay, suggesting the need for such oral hygiene practices. While we may not have precise descriptions of Anglo-Saxon tooth-care routines, the evidence from related cultures and periods suggests they did implement methods to maintain oral health to the best of their abilities.
