E-max is a trade name for a dental ceramic system. This page discusses assessment for lithium-disilicate glass-ceramic restorations. A material name alone does not establish suitability: restoration design, remaining tooth tissue and biting forces matter.

What is assessed before treatment?
Assessment covers decay, existing restorations, gums, shade and the bite, along with pulp health and possible cracks. A surface veneer and a crown covering the tooth may require different preparation.
How is treatment planned?
The restoration type is selected, the tooth prepared where needed and an impression or scan taken. Fit, contacts, shade and bite are assessed at try-in. Bonding or cementation depends on the restoration and clinical conditions.
Alternatives and limitations
Alternatives may include composite, other ceramics, zirconia or monitoring without restorative treatment. Translucency is not the only selection criterion. Removing healthy tooth tissue is irreversible, so the scope of cosmetic treatment needs careful discussion.
Risks and follow-up
Fracture, debonding, sensitivity, margin problems or a later need for root canal treatment are possible. Ceramic itself does not decay, but the underlying tooth and gums still need care. Reviews, interdental cleaning and management of clenching are important.

Frequently Asked Questions
Is E-max suitable for every tooth?
No. Restoration design, supporting tissue, bite and material limitations need assessment.
Does glass ceramic whiten the tooth?
A restoration shade can be chosen, but this is not whitening of the natural tooth.
Is it better than zirconia?
No single material is best for every case. Strength requirements, appearance, preparation and restoration design guide the choice.
