Hi,

I went to a dentist one year back for scaling, and I was suggested to use dental floss. So I tried using it for a week and then discontinued it. Now I have tooth sensitivity (whole mouth and all teeth) while eating icecreams and hot drinks, so I think of using dental floss regularly as suggested by the dentist before. But I need to know, can I use the dental floss which I purchased one year back, or would that have expired? What are the other ways you can help me?

Hello,

Welcome to icliniq.com.

I understand your concern.

Old dental floss can be used, but it depends on the embrasures or contacts between your teeth.

I request you share a clinical picture of either front or back teeth.

Dental floss does not cause any sensitivity unless some overzealous working is done.

Thank you.
