hi,
THANKS FOR ASKING QUERY,
You are having sensitivity in
canine tooth which can be due to many reasons like-
Gingival inflammation
Cervical abrasion due to toothbrush truama,heavey and regular consumption acidic drinks
Broken tooth
Deep caries .
I suggest you to visit the
dentist and get it checked clinically and radiographically.
Plan the treatment accordingly, prevent food retention in that area, use soft bristle tooth brush , do not brush harshly , use antiseptic mouth wash , use sensodent k tooth paste.
hope this will help you.
