Dental prostheses have to look good, feel good and be durable. Besides from an accurate execution and the quality of materials, the longevity of restorations also depends on the following aspects:

1. Oral environment health. If the dental crown is placed inside a mouth with numerous microbes in tartar, cavities or residual tooth roots not removed in time, the used materials will be damaged and the teeth will not last in time.
2. Dental pulp health (tooth nerve). Covering with crowns teeth with pulp issues that were not correctly identified and diagnosed before the treatment (even in the absence of any symptoms) involves significant risks in the future. They may require endodontic (root canal) treatment, after the crown is cemented. The integrity and aesthetics of the prosthesis will be affected.
3. It is recommended to maintain a proper dental hygiene and regular visits for checkup and professional cleaning: brushing, scaling, airflow.

Patients must be aware of their role in the longevity of their own dental prostheses:

• hygiene has to be correct and consistent, without pauses,
• care is required in consuming foods with a normal consistency,
• very hard or sticky foods should be avoided, no ice crushing between the teeth, no chewing of chicken bones, no biting of pencils, spoons, forks or eyeglass frames, etc.
• foods or drinks containing strong colorants: blueberries, raspberries, colored candy, red wine, coffee, tea, etc. should be avoided,
• smoking stains the teeth and dental restorations,
• wearing a mouthguard is mandatory when there is the habit of teeth grinding (bruxism).
