Root canal?
i believe its normal. a root canal doesn't mean your teeth won't be sensitive.
Reply:I'm not sure I'd worry about a couple seconds, but definitely if it's minutes they've missed something. Report It

Reply:You shouldn't be having problems with teeth that have had root canals. Did your regular dentist do them, or did you go to a specialist? Sometimes a regular dentist doesn't go deep enough and there is still a chance for an infection that can become sensitive.
Reply:i think u need to go back to ur dentist to check with them
Reply:Find another dentist.
