What returns to the tooth tissue?
Minerals can be incorporated into remaining tissue that was previously demineralised. Saliva supplies minerals; fluoride can support the process.
← All explanationsRemineralisation
Can early mineral loss be reversed?
Remineralisation means minerals are incorporated back into demineralised tooth tissue. This can stabilise early decay while the surface remains intact. Saliva and fluoride support the process. Missing tooth shape does not grow back as a result.

The surface is constantly exchanging minerals
Acids can dissolve minerals from tooth tissue. Saliva supplies minerals for the reverse process. Whether loss or replacement predominates depends on conditions in the mouth.
Early changes can become more stable
In early decay with an intact surface, mineral loss can be limited and partly reversed. Fluoride and suitable care support this.
A cavity does not close through this process
If the tooth surface has broken down, remineralisation does not replace the missing shape. An examination establishes whether protection and monitoring are enough or further treatment is needed.
At a glance
When can this process help?
In early decay with an intact surface, mineral loss can be partly reversed. An examination establishes whether these conditions are present.
What are its limits?
It does not rebuild a broken-down surface or a missing tooth fragment. Nor can the disappearance of a white spot be guaranteed.

Often confused
Remineralisation or reconstruction?
Remineralisation strengthens remaining demineralised tooth tissue. A filling or another restoration can replace lost shape. These are different processes.
Quick answers
Does remineralisation mean every cavity heals?
No. It concerns minerals in tooth tissue that is still present. It does not rebuild a broken-down surface or a missing tooth fragment.
Will a white spot definitely disappear?
No. Appearance and stability are different things. White spots can have different causes; the treatment aim depends on the findings.
Is one oral care product enough?
Conditions in the mouth matter: regular plaque control, suitable fluoride use and less frequent sugar exposure. Appropriate measures are discussed individually.
At the practice
For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Is the surface still intact, and how would we tell whether the change remains stable?
Preserving tooth tissue is part of the practice's approach. Possible steps are planned based on the examination.
We discuss what an unusual tooth surface needs after assessing the findings.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Mineral balance
- The interplay between mineral loss and replacement in tooth tissue.
- Initial lesion
- An early decay change where the surface has not yet broken down.
- Cavitation
- Breakdown of the tooth surface, leaving a defect; not the same as every early mineral loss.
Know the difference
Remineralisation concerns existing demineralised tissue. It neither replaces broken-down tooth shape nor automatically removes the need for restorative treatment.
