bottom front 2 teeth.

it feels like something is stuck between them. same feeling like when
food is stuck.

the dentist did a quick look but saw nothing and said to see how it is
after the   hygienist did a cleaning.  but i still have that feeling.

it does not hurt but i am frequently pressing my tongue against the
back of the teeth.
it feels like a tiny piece of string is stuck in between the teeth --
starting from the base of tooth close to the gum up to about halfway
up .the tooth.

never had the sensation before. just in the last few months.
