I have a local shop that sells all kind of falim gum. The best by far (hardest) are the smaller ones. The problem is the come in small package: https://www.amazon.com/Turkish-Chewy-Y%C4%B1ld%C4%B1z-Sugar-Stick/dp/B07PN7FB2Y/ref=mp_s_a_1_1?keywords=Yildiz+gum&qid=1560687382&s=gateway&sr=8-1
These ones are just as effective and come in bigger packages: https://www.amazon.com/Falim-100-Chewing-Gum-Damla-Sakizli/dp/B005GR1WO0
Edit: Sorry thought you meant falim gum. I'm not gonna delete the respons incase you or anyone else wonders
Falim is the most commonly recommended brand. It tastes better and has a more consistent texture than some of the raw tears I tried before.
I'm hesitant to use gum regularly though after asking my dentist about it. She advised against frequent gum chewing to avoid TMJ issues. That said, when I was chewing, I did notice some improvement with reflux, so it might be worth it if nothing else helps.
"Is this okay to buy? https://www.amazon.com/Falim-100-Chewing-Gum-Damla-Sakizli/dp/B005GR1WO0"
Yes, I dont see why not
"What does it taste like? Is it unbearable or you don’t really notice the taste"
It tastes like nothing tbh, it isnt unbearable to me but it might be to you if you have a sweet tooth
"How long + how many pieces should I chew? Would 1 piece on each side for 30 min - 1 hour a day work?"
As your face gets stronger the gum feels a lot more softer, I personally chew about 6 pieces for 2 hours a day. Make sure that you are chewing in great posture
"I’ve heard there are toxins in this but I think the minimal exposure (compared to everything else were exposed to wouldn’t harm me much)."
If you are talking about Tio2 and BHA there are no concerete evidence that they are harmful to humans at all, chew as much as you want
