Hi Mr. lybrate-user.
Gum surgeries are designed to improve the condition of loose teeth
due to advanced gum disease. So yes, it should help with strengthening loose teeth to an extent. However, maintenance of the results achieved would depend upon regular and thorough home care, and, regular follow up with your dentist.
As for the cost of treatment, it varies depending upon the nature of your problem, the exact surgery
planned, the need for, and the type and volume of bone graft
used, any ancillary procedures needed, etc. So it is tough to give you a quick
estimate without a clinical evaluation and appropriate radiographs. If you have doubts about the diagnosis, the planned treatment, or the costs, you may seek a second opinion with another dentist
All the best!
