Underneath a bottom molar. No sign of decay on the tooth, no swelling. Pain niggling for a week or so and suddenly getting much worse. There is quite a lot of receding gum so I suppose it must be an infection of some sort.
I have a massive work deadline and DH is away supporting MIL who has had operation so am on my own with 2 small dc.
What can I do to help at 920 on a Saturday night?
