MarketplaceFluoridexPosted on February 8, 2010. My mouth is extremely sensitive on the right side of my mouth, but not my left? Dentist has determined any specific tooth is causing the sensitivity. Have used Fluoridex but did not work very well. The sensitivity is so great that I do not chew on the left side. Any comments are appreciated. See if you have "cracked tooth syndrome. Thank you for your comments, I'll check with my dentist. Report Abuse CommentsThere are no comments.Leave a Comment | Popular My Friends |
