Subgingival calculus diagnosis and treatment
Subgingival calculus is hardened bacterial plaque below the gumline; a dental professional must remove it with instruments or ultrasonic scaling.
The short answer
Subgingival calculus is hardened bacterial plaque below the gumline; a dental professional must remove it with instruments or ultrasonic scaling. It forms when plaque mineralizes and becomes fixed to root surfaces or tooth areas hidden by inflamed gum tissue.
How does plaque become fixed beneath the gumline?
It forms when plaque mineralizes and becomes fixed to root surfaces or tooth areas hidden by inflamed gum tissue. Use gentle brushing and interdental cleaning, then have gum pockets measured and deposits removed by scaling or root-surface debridement when indicated.
What can you do about deposits below the gumline?
Use gentle brushing and interdental cleaning, then have gum pockets measured and deposits removed by scaling or root-surface debridement when indicated. Ask whether deposits are subgingival, whether pocket measurements show periodontitis, and which instrumentation is needed.
When do gum deposits require prompt or urgent care?
Seek prompt care for swelling, pus, loose teeth, persistent bleeding, or bad taste; facial swelling, fever, or trouble swallowing or breathing needs urgent attention.
What should you ask about gum pockets and scaling?
Ask whether deposits are subgingival, whether pocket measurements show periodontitis, and which instrumentation is needed.
