If you have open sores/cuts in your mouth, it's good to use a salt wash, so you put a small amount of salt into
cooled, boiled water, then swish it about and spit it out, don't swallow. (naughty folk I see you
)
That helps to lesson any infection and keeps it all clean for any dental work needed. It also helps heal up sores too.
If it's really painful, you can try a soluble paracetamol, again, swish around then spit out, it helps calm the pain down.
Nice bit about it being so warm, you can try some ice pops so they numb it a bit (ice cream is sweet, so it can set it off aching again).
When I have this type of issue, I resort to custard, rice pudding, soggy cereal, it's hard to find any foods that don't provoke it.
Hope you feel better soon x
