Occasional sensitivity to cold one year after filling

[Bita]

Hello all.
1-1.5 ago I had a deep cavity filling in one of my upper side canines. Now sometimes I feel this tooth is more sensitive to cold than other teeth. Sometimes I feel the sensitivity goes away. Pain with cold is not lingering and goes away very quickly. Is it something that I should be worried about?
Thanks so much.

Best to discuss your symptoms with your dentist. It depends on the cause of the sensitivity. Lingering would be an indication that something could be going wrong.
