This kid knew what he wanted and went for it.
Comic about Lucy doing a drawing demo for her kid’s 3rd grade class. She asks if anyone else has a drawing suggestion. One of the students demands “teeth!” She tried to clarify, “like, in a mouth, or…?” And the kid just screams “teeth!” Again and again, until she nervously draws a cartoon tooth and then the kid screams “yeahhhh!!”

this is SO COOL! #ToothyTuesday 🦷✨ narwhal tusks - the only functional teeth (= canines!) narwhals have (they also have a pair of partly-formed vestigial teeth) - look like single-directional spirals from the outside, but a new study shows they’re actually bi-directional spirals!

X-rays add new twist to narwhal's spiral tusk. New study finds that the tusks have a double helix structure—not one but two spirals, twisting in opposite directions. arstechnica.com/science/2026...

it’s #ToothyTuesday! 🦷✨ crabeater seal (Lobodon carcinophaga) postcanine teeth are, imo, among the most beautiful

the wavy, curved cusps on these premolars & molars reflect their function in filter-feeding krill (= marine crustaceans, thus “crabeater”)
This image depicts the anterior skull of a crabeater seal (Lobodon carcinophaga) in lateral left view, bearing postcanine teeth with curved cusps, which are used for filtering krill, tiny marine crustaceans (hence, “crabeater”). The largest cusp is the 2nd-3rd most mesial cusp, with 1-2 smaller cusps mesially and 2-3 smaller cusps distally. The largest cusp is especially curved, curving distally. Cusps are fairly blunt (i.e., not sharp), reflecting their use in filter-feeding. In addition to the postcanines, unicuspid incisors and canines are present.

it’s #ToothyTuesday! some of my fav teeth are colugo lower incisors. these teeth are pectinate or “fan-like,” exhibiting many long, thin projections used for grooming!

while colugos are sometimes called flying lemurs, they’re not actual lemurs: lemurs = primates, and colugos = dermopterans!
This image depicts the anterior, or front part, of the mandible, or lower jaw, of the colugo. The three incisors on each side of the jaw - especially the middle two teeth on each side of the jaw - are pectinate, or “fan-like” in form, with tooth crowns exhibiting many long, thin projections that colugos use for grooming.

ya know what? let’s bring this back #ToothyTuesday 🦷✨
This image depicts a frame from the comic, “Blobby and Friends.” Blobby, a pink blobfish that lives on land, is in the bottom left hand corner of the frame, seen in lateral left profile. Blobby is holding an upper molar in their left fin while looking at the tooth and smiling. In front of Blobby, a pile of human teeth rests on a dark purple surface with vertical light purple stripes. Blobby’s human, Lily, is in the upper left hand corner of the frame. She has blue hair worn in two top buns and is wearing a white and magenta horizontal stripe tank top, navy blue shorts, and slate blue socks. She has plastered herself against the wall away from Blobby, and is watching Blobby and the teeth with huge eyes while sweating profusely. A meme generator was used to modify this image, adding the text “IT’S #TOOTHYTUESDAY!” in white block lettering in the upper right hand corner of the frame, superimposed over the door to Lily’s right. The walls, door, and background are various shades of blue. Check out “Blobby and Friends” at https://www.instagram.com/blobbynfriends?igsh=aGhrZGZyZnhndGZj

It's Toothy Tuesday! 🦷 An Allosaurus fragilis right maxilla is slowly being uncovered. 🦖

The last image is a previously prepared Allosaurus fragilis left maxilla collected from the Cleveland-Lloyd Quarry in the 70s!

Did you know... pufferfish have four teeth that are fused like a beak? Feeding on invertebrates, they can use these giant gnashers to crack open clams and shellfish!

Kiki here. Hi, Tex! It is certainly a mystery why my human goes so often and I must go only once or twice a year! Either she enjoys dental treatments so much, or she’s not eating enough kibble. But it shall remain a mystery…because I don’t care to go with her to find out! Happy #ToothyTuesday!

The enormous tusks of hippos are formed from the top incisors and lower canines. Commonly used for defense and attack, these grow continuously through the animal's life and are sharpened as they are ground together!

Not much dino content for various reasons from me lately, so here's a quick vid of how I find Tyrannosaurus rex teeth while wandering in the badlands for #ToothyTuesday

SO SHINY! 🦖
