Plaque on teeth is not just "tartar" but a biofilm: calcium "houses" of bacteria, a sturdy armor against the immune system and many antibiotics.
Dr. Anna Malyshkina, a physician with 10 years of experience and a healthy-longevity consultant, explains the clinical picture of the phenomenon and its consequences for the oral cavity.

🦷 What the video covers:
🧫 What a biofilm is — an organized, resilient structure of microorganisms
🏠 The "calcium houses" metaphor — why plaque resembles dense domes
🛡️ Protection: how the biofilm blocks the immune system and antibiotics
🌊 Natural example: the slime on a river stone — the same phenomenon
👄 Why the mouth is an ideal place (moisture, saliva) and how this leads to plaque and tartar
📈 Scale: about 95% of bacteria live in biofilms
✅ Conclusion: plaque is a living, protected layer; a special strategy is needed to combat it

— The study showed that dental calculus is a mineralized biofilm that forms dense calcium domes, which mechanically protect microbial communities from the immune system and antibiotics.

— The authors assessed the distribution of bacteria in nature and confirmed that about 90–95% of microorganisms live in biofilm form as a widespread ancient survival strategy.

— The paper describes the molecular mechanisms of biofilm "armor" — the matrix barrier, slowed metabolism, and persister cells — which make it resistant to potent antibiotics and immune responses.

— The comparison showed that the slimy coating on stream stones shares properties with oral biofilms, and that moisture and saliva create ideal conditions for their formation.

— The study demonstrated that disrupting calcified dental biofilms requires special strategies (mechanical and chemo-enzymatic methods), since ordinary antibiotics are largely ineffective.
