premolars

Homo Sapiens have both, but our premolars and molars are less pronounced than herbivores.

Now, no-one was regularly removing premolars one the pre-modern era, and as I understand it the sort of crowding that might indicate removing premolars does cause (often minor, cosmetic) orthodontic issues.

Could you explain why a line graph is bad for a discrete but ordered variable, like [Molars - Premolars - Canines - Incisors]?

Also, the floss does not clean premolars and molars properly because of the shape of the teeth in interdental space (because of their concavity, imagine that the surface is basically made of two pillars).

Sealants are generally applied on adult molars and premolars as a child.

The molars and premolars, in turn, are used to crush food.

I went to some orthos who recommended removing two premolars, others suggesting jaw surgery.

Years after I had those out, I had two premolars removed under local anesthesia.

Many herbivores have overdeveloped incisors that are used for defense such as an elephant's tusks Herbivores tend to use premolars and molars to grind and crush vegetation.

I feel like there’s a contradiction in the article; it’s mentioned that the son, who was a ‘success story’, needed premolars removed, and that seemed to be portrayed as a success.

I don't care to explain like to a five year old, but the authors of the paper propose that only the modern human lineage have a total of four premolars in the lower jaw with a single root each.

Was curious and googled it, Invisalign has some limitations (mentioned in "Not ideal for") like moving teeth vertically and rotating canines or premolars.
