Hello there ,
Thanks for writing your query,
and weak teeth are the signs of periodontitis
, that is inflammation of attachment system of your teeth.
Treatment for this will be thorough oral proplyaxis that is professional ultrasonic cleaning and curretage of gums followed by medication.
But before going for treatment i suggest you few diagnostic tests
1. Blood sugar levels, fasting and postmeal both.
These tests will help your dentist
to rule out the cause of your problem and decide the treatment plan for you.
i hope this helps ,
