Hello and thank you for your question. Based on what you have stated, I would like to ask a few more questions for a proper answer.-Does the sensitivity leave within a few seconds from when the cold leaves the tooth?if so, then most likely the sensitivity is due to exposed root which is common.  The best way to reduce this sensitivity is to use Sensory or another antisensitive toothpaste.  You have to use this two-three times a day religiously for 3-4 weeks for it to START working.  You brush your teeth for two full minutes, spit out the excess, do not rinse out the film, do not eat or Chat Doctor.  This gives it time to work.  It takes weeks for it to gradually start working, but you will notice the difference. -Does the sensitivity persist for 15-45 seconds or longer after removal of the stimulus?if so then your dentist is right, you need root canal therapy because you have irreversible pulpits.  The composite is most likely to help close the gaps to make your teeth more aesthetic.  Best wishes and good health
