WEDNESDAY, June 28, 2017 -- Less is probably more when it comes to a convincing smile, a new study finds.

"These are significant changes in how these animals produce their shells that can be tied to a shifting ocean chemistry." Scientists at MSU analyzed the mineralogical composition of California mussel samples from Tatoosh Island off the coast of northern Washington.

The smiles differed in features such as amount, mouth angle, symmetry and how many teeth were shown.

Bigger smiles that showed more teeth tended to be rated as less effective, genuine or pleasant.

The findings could help guide facial reanimation surgery and rehabilitation for people with stroke and other medical conditions that affect facial expressions, the researchers said. National Library of Medicine has more on facial paralysis.

Findings from the study were published online June 28 in the journal PLOS One.
