Tooth Talk - Making Connections,Then and Now: Indian Oral Health Ethnobotany
By Mary Ellen Vohnsky. RDH. MS
“Native American peoples had a
remarkable amount of knowledge of the
world in which they lived. In particular,
they knew a great deal about plants.
There are in North America (defined as
north of Mexico and Hawaii and Green­
land) 31,566 kinds (species, subspecies,
varieties) of vascular plants: seed plants,
including the flowering plants (angio­
sperms) and conifers (gymnosperms), and
spore-bearing plants, including the ferns,
club mosses, spike mosses and horsetails
(pteridophyes). American Indians used
2,874 of these species as medicines, 1,886
as foods, 230 as dyes, and 492 as fibers
... (1,190 species for a broad range of
other purposes). All told, they found use­
ful purpose for 3,923 kinds of vascular
plants ... (and) 106 kinds of non-vascular
plants (algae, fungi, lichens, liverworts
and mosses).”1
You knew that. Did you know that
this knowledge included plants used for
treating oral health problems? OK, you
knew that too. What does all this have to
do with dentistry today?
Dental professionals and patients can
draw connections from the past to the
present (chew sticks and pine sap to Soni­
care toothbrushes and prescription tooth­
paste). Some of what we do in dentistry
today is similar to what American Indians
had been doing for millenniums.

Wear or abrasion would shorten a

enamel to reach the pulp, where the nerve
lives. Once the pulp was exposed, pain and
infection set in. This tooth would require
removal to find comfort. Documentation

this condition (i.e„ creosote).

Choctaw Indians used southern bayberry
