What is the natural film on teeth?
The acquired pellicle is a very thin film of salivary components, particularly proteins, that forms on tooth surfaces. It is part of the normal oral environment and can influence acid contact with enamel. It is different from bacterial plaque and does not make teeth acid-proof.

A film forms
Salivary components attach to a cleaned tooth surface. The pellicle is normally not visible as a thick deposit.
An interface develops
The film changes the interface between tooth and oral fluid. Its protection is limited and depends on conditions.
Distinguish plaque
Bacteria can attach to surfaces and develop a biofilm. Regular cleaning controls unwanted plaque; natural reformation of the salivary film is not a failure.

Notes on the teaching images
- A thin film of saliva components forms on tooth surfaces. The illustration is exaggerated and is not a micrograph.
- The pellicle influences the interface between tooth and oral fluid. The depicted shapes are not exact protein structures.
- Pellicle and bacterial plaque are not the same. Microorganisms can colonise the surface and form a biofilm.

Often confused
Pellicle or plaque?
Pellicle is mainly a salivary film. Plaque is an organised microbial deposit; the terms are not interchangeable.
Quick answers
Should the pellicle be scrubbed away?
Keeping teeth completely film-free is not a useful care goal. Appropriate oral hygiene and plaque control matter, rather than aggressive polishing.
Is it the rough deposit I can feel?
Not necessarily. Roughness may have other causes, including plaque or calculus. A microscopically thin pellicle cannot be reliably identified this way.
Does it reliably protect against acidic drinks?
No. Experimental protection does not mean complete protection in daily life. Frequent acid exposure can still damage dental hard tissue.
At the practice
For a personal discussion
Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Is what I notice on my teeth plaque, tartar or something else?
Noticing a rough or discoloured deposit? Examination can distinguish its cause from normal surface-film formation.
