Do government clinics use ultrasonic scalar or manual scalar?

I realised that my second lower molar have Overhanging Dental Restoration where the floss will go into a 'crackline' when floss is pulled up from the distal side.

Restoration was done 7 years back (a second deep restoration I believe as the first restoration many years back failed or cracked and had to be redone).

Over years I feel sensitivity at gumline distal side of this tooth. Now I read that ODR can cause periodontal problems around the tooth or even decay.

I told my dentist 2 years back about this sensitivity she tried probing the biting surface and told me the filling is ok. I did not research about this ODR at that time so I couldn't tell her this.

So what should I do about this tooth? If I go back and tell them about ODR, can they detect it with their probe?

Wisdom is behind it. But there is a slight gap there because that wisdom is somewhat horizontally partial erupted.

On the other side, my previous dentist did a filling that joins the horizontal wisdom surface to the 2nd molar in front, so it closes up the gap. And I find that pretty good so far.
