No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Your baby teeth and adult teeth all began developing before you were even born. Our DNA still contains all the genes that sharks use to grow their endless conveyor belt of replacement teeth, but in humans these genes are deactivated by the 20th week of foetal development.
The advantages of keeping the same teeth through adulthood is that they can be securely anchored in the jawbone, which allows us to chew tough plants and grains.

though a drug is being developed that could allow us to regenerate teeth
You’re saying we could reactivate the gene and get infinite teeth?? 🫨
Possible, but it may come with downsides you don't like.
Let me guess, the downside is infinite teeth.
The downside could be something that nobody has imagined yet. That is the problem with change. I'm not against this, but I demand reasonable study. (but not unreasonable levels - vaccines and GMO have been studied enough to conclude they are generally safe despite people yelling more study needed)
Teething 3.0.
Imagine teeth grew like our nails and had to be clipped regularly
Stop
I hate that, please stop
Rodents then?
Subscription based teeth?
worse, you have to pay to stop them from growing
Side effects may include dry mouth, diarrhea, attacking swimmers at the beach. Do not take Teethenall if you are allergic to shellfish.
That I could live with.
Isn’t this the Street Sharks origin story?
Are those the snapping guys in West Side Story?
Nah, these guys

Vagina teeth? That's my fetish.
That sorta makes it sound like a nightmare
I could be wrong, but I don't think that's how the drugs in development work. They cause the existing teeth to produce more enamel or something.
you are wrong. all their tests are on subjects missing teeth, not with reduced enamel. this is literally growing replacement teeth.

I stand corrected. Thanks!
I was thinking of this:
https://dental.washington.edu/trials-begin-on-lozenge-that-rebuilds-tooth-enamel/
But your link is far more exciting.
Hopefully that's what it ends up being, as the idea of growing new teeth has been around in science and media for a long time.
The latest work I've seen reactivates the genes to start growing any existing teeth that had stopped. It's for early development problems in children, not for adults. But of course the media seized on the "regrow teeth" part and ran with it. Unless there's a way to implant new teeth seeds and then get them going, adults are still out of luck.
Teeth cannot produce enamel. Enamel is not a living tissue and it was produced by cells outside of the tooth in a coral-like manner. In order to grow a new tooth, you need it to be fully surrounded by specialized living tissue for the whole growth cycle.
PS: I honestly expected something like this to come out of bioelectric computation research, but progress seems slower there. Or rather knowledge and techniques in other fields is reaching critical mass, giving us these advances.
Maybe "produce" isn't the right word, but I was thinking of these lozenges that made headlines a few years ago.
I think the last time I was this excited about medical science was the COVID vaccine. How I would love to replace my root canal crowns with real teeth!
