Not sure what's available where you're at without a prescription, but I recommend Orajel or any equivalent ulcer/tooth ache gel.
In addition to the other things you're already using, you can steep black tea bags in warm water and gently bite on that. The tannins help with bleeding and inflammation.
A mouthwash or spray with Cetylpyridinium Chloride in the ingredients list will help with healing, but don't buy a mouthwash that has alcohol/isopropyl in the ingredients. Dentyl, Oral B Gum detoxify, Parodontax, Biotene Dry Mouth Spray are all good.
I had several teeth removed from my inside my jaw that never came out and had a bone graft placed in the area that had to heal for 6 months before dental implants were placed. The mouthwash definitely helped me heal faster from that surgery than when I had my wisdom teeth out the year before and didn't use any. Just do a gentle rinse dont swish it around hard! You don't want to disturb the blood clots and get dry socket.
I hope you start to feel better soon!
I had issues with dry eyes and wasn't a good option for lasik, so I had EVO Visian Implantable Collamer Lens surgery 2 years ago. Was $3500 per eye so $7000 total.
It's not very well known. I had to ask for it specifically and even the receptionist thought I meant lasik until I clarified where it was listed on their own website.
It's similar to cataract surgery but instead of removing your lens and replacing it; they just add a second one with your prescription in front of it. Basically it's a permanent contact.
They slice a very small incision, slide in the folded lens, and then smooth it out. Takes 20-30 minutes. Doesn't remove any tissue from the eye like other procedures or leave a flap. It can be reversed by removing the lens in another procedure, and can be redone in the future if your prescription changes a lot. They can also correct an astigmatism using these lenses.
After surgery, I wore eye shields at night for a week, and had to do the same eye drop protocol that is done after cataract surgery. 3 bottle of drops, 3-4 times a day for around 21 days. They had a single bottle option that combined all the meds which would've been only 1 drop 3-4 times a day, but it was $200. So I filled the 3 bottles at the pharmacy for a total of $30 instead.
Vision was perfect right after surgery. Eyes felt mildly dry for maybe 2-3 days but that could've been some of the drops.
So happy to not spend $800+ per year on contacts and solution, or worrying about losing a contact while swimming. I would do it again if it's ever needed.
