Three teeth of my upper right side went numb four days ago. Prior to
that for about a week I had severe headache on the same side. I took
aleve once a day for two days and the headache was gone. Just now I
realized that there may be a link between these two things. I will
take an appt with my dentist first thing monday morning but I want to
ask here if anyone knows anything about numb teeth.

I started using listerine whitening mouthwash a week ago. I thought
this numbness might be due to that because listerine tends to be very
intensive.  It doesn't make sense that only 3 teeth would go numb. I
stopped using that now.

Any thoughts are appreciated.
