Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from severe dentinal
hypersensitivity of teeth and it occurs due to opening of
nerve endings leading to irritation of nerves and causes sensitivity..
In case if there is a generalized increase in sensitivity that is in all teeth then you need to start using desensitizing toothpaste twice daily, gently
massage over the gums and leave for a minute and brush off with it..
You should also avoid extreme hot and cold foods..
In case if the condition still does not improve
consult a dentist and you will need to get full mouth
x ray done to rule out the cause and get treated accordingly.
Hope this information helps..
Thanks and regards.
