Without going into details of what this dentist has diagnosed,..I can see that your jaws tend to tighten when you take cold food,..There are various reasosn which cause this,... One of these could be stress,..and cold food is a stimulus for this to happen,.. Do u live a stressful life,..I mean odd job hours,...and do have pain in the jaws,..when u get up in the morning,..which could be a sign of grinding your teeth in the night,...which again could be a sign of stress Jaw muscle spasms can also be caused by badly aligned teeth,.. Since the Dentist u saw has not said anything about ur teeth alignment,..tht cannot be a problem,... So,..the most probable case could be stress,... so what I would suggest is tht u chill out for some me,...avoid the triggers of this episode,..which is cold food,..for sometime,.. Maybe 4-5 weeks,.. Things should smoothen it,...

Get your wisdom tooth removed if its not in alignment with other teeth.There is no point keeping it if its going to cause pain and discomfort later.Get it done when young.Get the cavity filled.If its too deep then go for RCT and crowns.Your problem should be solved without much difficulty.Take care.

i also have an issue when i drink anything cold my jaw muscles ache he relates it to this condition. have had pains in my jaw, for the past few months now...and more recently i noticed a cavity in my teeth when i decided to see a doctor thats when he advised that i have 4 issue s one a cavity in the upper molar. two right 3 molar has to be removed three the other 3 molar bottom left side has a hockey stick shaped root hence i need surgery. four my muscles around my jaw tend to freeze , like a spasm each time i have something cold (like cold water etc) while the first three can be taken care of ..i was jus wondering what this condition is actually called , if you could advise
