thanks for sharing your concern.
your statement shows that
you are really taking care of your tooth but this alone will not solve the problem.
you have periodontitis
that is why you are feeling loosening of teeth.
for this you will have to visit your dentist
and get an OPG xray done.
that will explain how much infection is there,whether any bone loss or not.after knowing these details your treatment can be planned.
i would say get yourself examined before it progresses further. meanwhile you can use tannic acid
gum paint for massaging your gums.
hope this helps.
