You could add nuts like shelled pistachios or walnuts as snacks. Even mix things together to make your own granola/snack mixes with dried fruits, nuts, oats. And you can make different varieties so it doesn’t get old. Example: Almonds, dried cherries, oats. Or pistachios, dried cranberries, pretzels
Or you can buy them, there’s a huge variety of sweet or savory and even spicy in stores.
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!
