Dentist was unable to take pictures because of gagging. Is it really my gum that's infected?
Edit: added a much better picture
I don't drink or smoke. Some backstory:
My left lower wisdom tooth and the molar next to it hurt. This started a few weeks ago with some uncomfortable tingling which went away after a few days.
Wednesday: I tried to remove some food from between my front teeth with a tooth pick, which made my gums bleed. The whole area started hurting again. I tried using clove oil, vanilla extract, salt water rinses. Apart from the salt water, everything made it worse.
Thursday: the pain had become unbearable. It was a burning sensation in the area that radiated to my ear when I moved too much. My partner bought me chlorhexidine and diclofenac. Ibuprofen, paracetamol and diclofenac all didn't remove the pain even a little bit. However, by Friday the pain was less bad. Chewing did give me stabbing pain but that stopped too and it has been stable since.
From Friday to now it's been mostly waking up with sensitivity in the area and then later in the day a throbbing in step with my heartbeat. It feels as if it is under my second molar. Not painful exactly, but extremely annoying and making it hard to concentrate on anything else. It gets worse when I lie down. Painkillers still do nothing.
Yesterday I went to the dentist. She looked, felt my gums, tapped the teeth to test sensitivity, scratched my gums in the area. She asked me if I'm sensitive to hot or cold (been sensitive to cold in that area for years). She wanted to take a picture but I gagged whenever I had to bite down and couldn't keep it in place. She said there's another way to take pictures, but that would have to happen in the hospital. I guess she was referring to the oral surgeon?
Her judgement was that she didn't see much to worry about. She said that my wisdom tooth was probably causing my gum to be infected. She said she didn't see caries or tooth decay that would cause this pain. I asked her about the blackness on the wisdom tooth and she said that it's caries in the beginning stages. She said the wisdom tooth eventually needs to be removed but not at emergency speed. She prescribed me chlorhexidine and said if the pain doesn't stop, to call for antibiotics.
My question is: is she likely to be right? Can I trust that this will go away after a few days of chlorhexidine?
TLDR: I've had painful radiating tooth pain that shifted into continuous throbbing that felt like it was under my second molar. Dentist couldn't get an x-ray because of gag reflex but suspects pericoronitis. She prescribed chlorhexidine and suggested antibiotics if pain doesn't improve. Can I trust her judgement?
