Which areas does a partial crown cover?
It includes damaged areas of the chewing surface and, where needed, tooth cusps. Suitable outer surfaces can remain uncovered.
← All explanationsPartial crown
Why might a tooth not need a full crown?
A partial crown replaces a larger damaged part of a tooth and includes the chewing surface. Unlike a full crown, it does not surround all the tooth's outer surfaces. The examination determines which areas can be retained.

Covering weakened areas selectively
Larger defects may require parts of the chewing surface and tooth cusps to be covered. A partial crown is planned to preserve suitable natural tooth structure.
Not every surface is covered
The restoration replaces and covers the selected areas. Unlike a full crown, it leaves suitable outer surfaces of the tooth uncovered.
Remaining structure and bite guide the design
Coverage, material and attachment are tailored to the tooth. A partial crown is not suitable for every defect. Its fit and contacts with other teeth are checked.
At a glance
When is it considered?
A larger defect may leave parts of the tooth needing coverage. Remaining tooth structure and biting forces determine whether a partial crown is suitable.
What guides the planning?
Coverage, material and attachment are tailored to the tooth; fit and contacts are checked. The natural tooth beneath a partial crown still needs care.

Often confused
Partial crown or full crown?
A partial crown leaves suitable outer tooth surfaces uncovered. A full crown surrounds the prepared natural crown. Neither replaces the tooth root.
Quick answers
Is a partial crown the same as an onlay?
The terms overlap but are not used in exactly the same way everywhere. What matters is which surfaces and cusps the particular restoration covers.
Does every root-treated tooth need a full crown?
Not automatically. The restoration also depends on the remaining tooth structure and the forces it bears. One rule does not fit every tooth.
Can new decay develop beneath a partial crown?
The natural tooth remains susceptible at the junctions and exposed surfaces. Thorough cleaning and check-ups therefore remain important.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Which surfaces of my tooth can be preserved, and where would protective coverage be useful?
Her approach combines tooth preservation with functional and aesthetic planning. The starting situation is assessed before deciding on a restoration.
An examination helps us assess how much tooth structure remains and which restoration may suit it.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Tooth cusp
- A raised part of a back tooth's chewing surface; its stability influences whether coverage is needed.
- Partial coverage
- A restoration design that preserves suitable parts of the natural outer tooth surfaces and leaves them uncovered.
- Occlusion
- How the upper and lower teeth contact one another; this is considered when planning a restoration.
Know the difference
The size of the visible defect alone does not determine the restoration. The stability of the remaining walls and cusps, and the forces on them, also matter.
