### input:
I have a horrible tooth ache, #19.   Some history.  I recently got my braces off after having them for 2.5 yrs.   about a year ago, this same toothe started bothering me when I would bite down.  At my regular dental checkup, I told my tent its and he checked the bite and said it was off, so he file the tooth down just a little bit.  It was fine after that.  Then about 6 months ago, while I still had my braces, the same tooth started hurting again.  Only that time much worse than before.  It came on very quickly, and felt like the tooth had raised up over night, so that every time I closed my mouth it hit the top teeth.  The pain was horrible.  I couldnt bite down on anything.  I went to the dentist and he checked it, and again my bite was off.  He filed it down, and I had immediate release, however, it wasnt 100%.  He did X-ray it and and mentioned a brown spot on the root, but sati that it could be because of the orthodontia work, so said hed monitor it.  Since then, Ive tended to avoid eating anything on that side for fear of it hurting.  Sometimes I would try it just to check and it felt okay, but not perfect.  More recently, it has been more sensitive to cold.  Ive experienced this off and on through my life, so it didnt concern me until this past month when heat started bothering me.   This was a mild irritation until last week.  Now, it hurts dreadfully, And not necessarily in response to temperate changes.   It can be fine one minute and the next I feel like crying it hurts so bad.  At first it was just the tooth and then gum around the tooth.  Now when it hurts, its like its throbbing around several teeth and in my cheek.  I went to the dentist this morning, and he took an xray and said it looked fairly normal.   But because of my symptoms, he could see som areas where it may be a problem, so he referred me to and endodontist.  Well, now its been throbbing off and on all day.  The whole lower side of my mouth hurts and so does that side of my tongue and neck.  And for some reason, a spot in the roof of my mouth is sore.  Why is my neck, my tongue and that spot in the roof of my mouth hurting?   Is this typical?

Hello:)Welcome to Chat Doctor. Repeated episodes of heat and cold sensitivity suggests you have a pulpits on the tooth. Also, the dark spot around the root suggests a periapical infection. Dental pain can be radiated to the neck, ear, head, and whole jaw as in your case. Do not worry, take a Novato 500 for 5 days b.i.d. Also take Idol plus (analgesic) t.i.d for 3 days.(Make sure you are not known allergic to these medicines, not asthmatic). I suggest you to get the x-rays done and go for a root canal on this tooth. Also check if there are nearby teeth which are also infected. A root canal for this tooth will ideally remove the infection and eliminate pain. You did not mention if you use a retainer. Check if it's hurting on your palate to get it trimmed. Regards.
