Cracking Teeth

Take a look at smiling photos of yourself and you won’t spot these but they’re there. Microcracks (MCs). These tiny cracks in the hard outer coating of your teeth (enamel) develop with age. How do they affect tooth structure and integrity? Researchers investigate using X-ray micro-computed tomography of four extracted human teeth. Image processing using specific algorithms allowed the team to create 3D images of the density of the enamel (top row) and softer inner tissue (dentine, middle row), as well as MCs (bottom row) from different angles (left to right). This revealed an intricate star-shaped network of MCs that weren’t limited to the enamel but passed through into the dentine along two almost perpendicular planes. These healthy teeth nonetheless retained their structural integrity. MCs may therefore be involved in protecting tooth integrity from the strong forces applied to teeth daily. More research is needed to uncover how.

You'll get a job no problem, I'm sure of it!! Please fix my teeth, my dentin is exposed and they're yellow from coffee lol

Haha I feel you on the coffee 💀 But hey, black tea is sooo much more worse when it comes to yellowing teeth.

Oh no that exposed dentin has to be uncomfy :( We apply GLUMA on areas with a low risk for cavities and do fillings on higher risk areas, maybe that could help. But I know that dental treatments are super pricey, it's a whole ass farce, tbh. We were able to offer fillings and root canals for free at my dental school, if that's feasible for you I'm sure the students would love to do some low-drill fillings.

(also it might come from you applying too much pressure while brushing your teeth which can also make your gums recede! i had my fair share of 'clean-focused' patients with receding gums who brushed too often and too hard -- too much is unfortunately also bad for us)

[ajaneofmanytalents]

I gotta say, of all the possible aftereffects to be lingering more than a week after interim dental work, "the occasional taste of cloves" is downright lucking out.

[toothpasteforsensitiveteeth]

Dental Sensitivity, also known as dentin sensitivity, is a common dental condition that is experienced when something hot or cold comes in contact with your teeth. To be more specific, it occurs when the dentin is exposed to thermal, chemical, or osmotic stimuli, resulting in extreme tooth sensitivity and discomfort.

Shrimpmer!Reader

Floyd Leech X GN!Shrimpmer!Reader X Jade Leech

Warnings: Mild Violence, Brief Mentions of Accurate Shrimp Cleaning Methods (kind of gross)

I literally had written up a mini fic showcasing the tweels first meeting Shrimper!Reader… and lost it. Have no idea where it is. Searched through my drafts and got pissed, so just started over from scratch.

Can be read as platonic but with a lot of sus behavior ngl

The Basics (aka an Introduction to Shrimpmer!Reader)

Shrimpmer!Reader is a cleaner shrimp, a type of shrimp known for cleaning off parasites, algae, insects, and other bad stuff from fish. They’ve even been known to eat the mucus and infectious material around a fish’s wound to reduce infection and aid in healing. There are different species of cleaner shrimp, ‘scarlet skunk’ or ‘white-striped’ cleaner shrimps being known for cleaning the mouths of moral eels specifically.

Shrimpmer!Reader specifically comes from a family of cleaner shrimps that have a long-standing business partnership with the Leeches. Their family provides their cleaning and patch-up services to better the mereels’ health and heal any injuries, and in turn, the Leeches provide protection. It’s a mutualistic relationship where both benefit. And congrats, they were assigned to the tweels when they were but a mere fry and twins were still little elvers.

But what is it that Shrimpmer!Reader does exactly? Well, they have a cleaning station set up (i.e. a flat rock for the tweels to lay on while they work) and they go over the twins’ body, ridding it of any parasites and other debris. Picking at their scales and skin like a fine-tooth comb. They’ll even clean their sharp teeth using specialized brushes and tools to make sure nothing is stuck and strengthen the dentin (real shrimp physically go inside eel’s mouths, but shrimpmers are too big for that). Whenever the twins come to them with an injury after one of their scuffles, Shrimpmer!Reader will clean and disinfect the wound, being sure to remove any parasites, then wrap up the wound to heal faster.

In terms of anatomy and size difference, Shrimpmer!Reader is much smaller compared to the twins, but not on the same scale difference as real shrimps and moray eels. They’re not tiny enough to fit in their mouths but are small enough to be carried with ease. The best comparison I can give is like with the dwarves and Neige, but the tweels’ eel forms are much bigger compared to regular humans, so Shrimpmer!Reader would be shorter compared to a human as well. Floyd would joke about them being “child-sized.” Just like the Octatrio, their bottom half is that of a white-striped cleaner shrimp while the rest of their body has the matching miscolored skin, fin ears, and a pair of long, white antenna on the top of their head. No, their hands aren’t claws/pincers, but they do have sharp nails that aid in cleaning.

The Shrimp and the Eels Headcanons

Like mentioned above, Shrimpmer!Reader was assigned to Floyd and Jade back when they were all still children. Each new generation of Leech ends up being assigned a cleaner shrimp who are around the same age so that they can grow together and build a proper symbiotic bond. You just ended up unlucky ‘cause Mr. and Mrs. Leech had twins and you were the only available one in your family at the time. A two for one deal, as it were.

Rough first meet (the twins are asses even back then), but you eventually adjusted and they learned how much they actually enjoy getting all those nasties off of them. You were gentle and efficient, it was very soothing, almost therapeutic to them. But it was only after one particular cleaning where Floyd came to you, a week after he got into a fight, wound infected and riddled with parasites, that they fully realized just how much they needed you. Neither twin skipped a cleaning or wound treatment after that.

You are tiny and not built for fighting, so the twins are more than happy to do so for you!~ Some predator is stalking you, trying to get a taste? Floyd is already grabbing them by the tail, pulling them away from you and towards his own dangerously sharp jaws. Another merperson is bulling you, picking on your smaller size? Jade’s looming right behind, tail at the ready to squeeze the life out of them. Most of your patch-up work was from attending to their wounds sustained in fights defending you.

Floyd and Jade both have their tails wrapped around some poor, unfortunate soul who was pulling on your antenna. Jade is taunting the crying fry while Floyd is “playfully” biting their tail fins.

“Jade, Floyd, let them go already. You’re going to get in trouble…”

You do meet Azul later on, though never quite befriend him per say. His contracts made you uncomfortable and untrusting of his intentions. In turn, Azul was stiff and reserved around you on the account of the overly protective eels threatening to chew his tentacles off if he tried anything.

You’re not a student at NRC nor a student of RSA. Magic isn’t your forte (or your concern really), the tweels are. Which is why you do visit the schoolgrounds frequently, especially after the two (mainly Floyd) start complaining about “needing their shrimp.” They’re not even in their eel forms most of the time, but they do still get into fights and the nurse on staff isn’t good enough.

Congrats, you’re now the Leech’s designated Health Support Cleaner Shrimp, or whatever bullshit the twins pulled out of their tails when forcing requesting to Crowley that you be allowed to stay at Octavinelle! Double congrats, because you also work at Mostro Lounge as a janitor because you literally clean for a living!

In your human form, you are much shorter than most of the other students and you have two long cowlicks that resemble your antenna. You aren’t the biggest fan of this form, finding two legs to be difficult to navigate, especially since you kind of skipped the prep class. Floyd was impatient and claimed him and Jade would just teach you themselves. An unwise decision really.

I mean, you could also just request to have the potion adjusted so you can be taller too, I guess idk the twins aren’t going to tell you that.

You sometimes turn back into your merform with the tweels and swim together because you miss it. Floyd definitely missed curling his tail around his little shrimp and pinning you down with his much bigger size. He especially loves to flip you on your back and watch your little feetsies wiggle around in a panic.

Jade misses the cleanings more than anything else. Being a vice dormleader while also working at a lounge and doing schoolwork is stressful for one eel. So, being able to just relax and have you attend to him while he prattles on about mushrooms is absolute heaven. That’s not to say he doesn’t mess with you either. Jade will gladly use your height against you by putting your cleaning supplies on a higher shelf, so you’re forced to ask him for help, teasing you all the while.

No, you can’t clean anybody else, merfolk or otherwise. Only them. Azul almost lost a tentacle after suggesting such a thing when he noticed business was running slower.

You’re their cleaner shrimp, and they’re your eels. Anybody aware of the Leech’s influence know to back off lest they end up missing under mysterious circumstances.

Oh yeah, and the tweels, at some point, made it a habit to kiss you after you finished cleaning them under the guise of you “cleaning their teeth.” It’s become something so casual between you three now that when Azul caught sight of the twins and you locking lips, he nearly fell over at not realizing the three of you were (supposedly) an item.

To the extent you feel comfortable sharing ofc - why do you need a mouth reconstruction? Is that something dental insurance doesn't cover?

Best of luck for your recovery <3

I have a combination of very weak enamel and furious teeth grinding. The combination meant that my teeth were sheered down until the enamel was gone. I was down to just the dentin underneath, which means my teeth were only going to start eroding faster. Multiple dental providers were saying that I was on track for dentures by fifty. I was super cold sensitive on one side, and I had a tooth pulled on the other side due to a botched root canal, which meant there was no way to comfortably chew many types of food. It was affecting what I’d choose to eat, and buddy I do NOT need more obstacles to eating. And just aesthetics-wise, my teeth’s appearance didn’t bother me enough to pay this much just for them to look better, but I didn’t love that they were permanently yellow and that my face was losing height due to how small my teeth were.

(I’m convinced my prosthedontist and my dental surgeon were both more bothered by the aesthetics of my mouth than I was. My surgeon literally said, “I bet you were pretty insecure about your teeth before this, right?” And I was like “ummmm not really?“ and he was like “really? I mean good! But please understand they look so much better.”)

So I got gum surgery and a base for a dental implant installed several months ago, and now I’ve got temporary crowns in which are actually these connected blocks of teeth that I need special floss to take care of.

They’re So Big and So White.

And tomorrow I get my permanent crowns which should look and feel like real teeth! And then after that I get fitted for a mouthguard to prevent me from wearing the new ones down to nubs as well. (You can use an over the counter mouth guard for grinding, which is what I was using while I was buying time to get my teeth fixed. I’m getting in custom fit in the hopes my jaw will be less sore when I wake up. Any mouthguard is better than no mouth guard if you’re a grinder though, trust me. Save yourself the enamel and the money.)

Speaking of money, I’ll be super blunt: in total, I paid about $8000 for the gum surgery and implant, and $36000 for almost entire mouth of new crowns (I’ve only got two original teeth left). Insurance covered a little over half the surgery fees and like $2k of the crowns. (My insurance will pay for up to 50% of the price of a crown every two years, and I need about twenty crowns all at once, so. Yeah.) I investigated going to Mexico or Canada to get the work done, but ultimately my dental situation is complicated enough to require coordination of multiple providers and regular check ups over many months. It was going to be to complicated to arrange that internationally, plus travel and lodgings, to be worth the diminishing amount of money I would save. I do think I could have gotten all this work done for cheaper, but I’m not sure if it actually would have been something I followed through on. And basically, the sooner I get this work done, the better in terms of face shape and teeth migration and all that, so I was like “fuck it let’s go,” so here we are. In twenty-four hours, I’ll have a brand new mouth.

I’m sorry, whale sharks have WHAT teeth??

Whale sharks, like other sharks, have their skin covered by dermal denticles! They are a type of “scale” that reduces drag in the water and offers great protection — the dermal denticle, while on the outside of the body, is a kind of tooth, in a way, with a pulp cavity, dentine, and an enamel-like top covering. That’s what I was referring to with “skin teeth”! Though, it’s admittedly little more complicated than that… see, recent evidence suggests that dermal denticles or their scale ancestors actually came first, and our teeth are really modified scales. Despite that people still like to call dermal denticles “modified teeth”, because they’re quite different from the scales of bony fish. Also a good way to do shock value if you’re into that thing — seems a lot more gnarly to talk about “skin teeth” as a shorthand than it is to discuss “dermal denticles” haha

Whale sharks not only have dermal denticles on their skin, but also on their eyeballs! They are different in structure to normal dermal denticles and are thought to protect the eyes, pretty nifty for them!

This Wet Beast Wednesday I'm going to talk about gars. This needs some clarification because there are a lot of different fish called gar, garfish, or garpike. I'm referring to fish of the family Lepisostidae, the only surviving members of the ancient clade Ginglimodi, which I mostly brought up because Ginglimodi is a funny name.

(image: a longnose gar)

Gars are predatory fish found exclusively in North and Central America, though they have been introduced outside of their native range. Their ancestors evolved in Triassic period and once occupied most of North America and large portions of Europe back when the continents were still connected. They are freshwater fish, though a few species will go into brackish or even marine waters temporarily. The name "gar" is though to come from the old english word for "spear", which is appropriate as gar are very elongated fish and often have pointy snouts. Many other groups of elongated fish are also given the common name of gar or garfish for this reason. Their long snouts are filled with sharp teeth which are used to crush through shells and flesh. Gars are opportunistic predators who feed largely on crustaceans, frogs, and fish and will eat carrion if they find it. The long snouts are also used to dig through sediment in search of prey They move slowly through the water, but are capable of short bursts of speed to catch prey. Most species are apex predators with no natural predators as adults.

(image: a longnose gar with mouth open, displaying the teeth)

The body of a gar is covered with thick, diamond-shaped scales. Their scales are an ancient variety known as ganoid scales which are notable for their shape and composition. Where most bony fish scales have layers of a spongy, bony substance called cosmene, ganoid scales instead have an enamel-like substance called dentine, which is also a component in teeth. The scales are also covered in a rigid, glassy substance called ganoine where other scales use enameloid. Ganoid scales also don't overlap, instead laying next to each other in a manner that provided protection while still allowing flexibility. The result is a suit of armor that makes gar very durable. Because of how durable the scales are, they habe been used by humans for many purposes. Multiple Native American groups would use scales as arrowheads, there are reports of native Caribbean peoples wearing breastplates made of gar skin, and Europeans colonists would layer their plow heads with the scales to protect the,. There is currently a market for jewelry made of the scales.

(image: a close-up of ganoid scales)

Gar typically lay their eggs in early spring, with the female coating vegetation with thousands of sticky eggs. The eggs are toxic to humans, capable of causing sickness when ingested. Because of this, they are unsuitable for caviar. Scientists initially thought that the toxin was an adaptation to prevent predation, but natural predators of the eggs like channel catfish and bluegill are immune. Crayfish are affected by the eggs, though it's not clear if the poison is an adaptation targeting them or not.

(image: a shortnose gar)

The swim bladder of gar is highly vascularized, allowing them to act as lungs. Most gar will surface occasionally to take a gulp of air. While they are capable of surviving on their gills alone in good-quality water, air gulping allows gar to thrive in low-oxygen water where their prey will be sluggish from oxygen deprivation. Most species live around 20 years, but the alligator gar can live upwards of 70 years.

(image: a spotted gar)

There are seven living species of Gar: the Cuban gar, tropical gar, spotted gar, longnose gar, shortnose gar, Florida gar, and alligator gar. The shortenose gar is the smalles species, reaching an average length of 62.5 cm (24.6 in) while the alligator gar is the largest species and one of the largest of all American freshwater fish at an average length of 1.8 m (6 ft) in length. The largest alligator gar on record measured in 2.57 m (8 ft 5 in) and 148 kg (327 lbs). Alligator gar were long considered a nuisance species by fishermen as they preyed on sportfish and as a result, they were frequently killed. This resulted in population losses and the fish being extirpated from many states it was once native to. Now multiple states have laws and regulations protecting them and the population is starting to see a resurgence. Alligator gar and now a popular sportfish and have been introduced to places outside of their native range, becoming an invasive species in many areas including China.

(image: two fishermen with an alligator gar)

Gar meat is edible and is described as having a very unique taste compared to other fish meat. They are not commonly eaten in modern times, but some people consider them a delicacy. Gar meat is known to carry environmental toxins like pollutants and heavy metals, which can make eating them risky. Gar are mostly fished for their scales or for sport. Only the Cuban car is endangered (and critically so) while other species may be locally endangered, but as a whole are not threatened. Gar are used as aquarium fish due to their unique appearance, though they need large tanks due to their size.
