Hammaskiilleen

Hammaskiilleen, also known as "hammasliina" or "hammasväri," refers to the traditional Finnish practice of using natural, plant-based dyes to color teeth. This custom was particularly common among the Sámi people, an Indigenous group in northern Scandinavia, including parts of Finland, Norway, Sweden, and Russia. The practice was believed to have both cultural and practical significance.

The dyes used in hammaskiilleen were typically derived from plants such as birch bark, rowan berries, or other local flora. These natural substances were applied to the teeth in various ways, often by rubbing them into the enamel or using them as part of a mouthwash. The resulting coloration varied, ranging from subtle yellows to more pronounced browns or reds. While the exact reasons for this tradition remain debated, it was sometimes linked to social status, protection against tooth decay, or even spiritual beliefs.

Historically, hammaskiilleen was not widely practiced outside Indigenous communities, and its use declined as Western dental hygiene practices became more prevalent. Today, it is primarily studied as a cultural artifact rather than a common practice. Some modern enthusiasts and cultural preservationists have revisited the tradition as part of efforts to honor Sámi heritage and traditional knowledge.

The practice should not be confused with contemporary tooth-whitening trends, as hammaskiilleen was not intended to improve dental aesthetics but rather served symbolic or functional roles within its cultural context. Archaeological and ethnographic research continues to shed light on its historical significance and the broader cultural practices of the Sámi people.
