1. Definition: What is a Dental Crown?
A porcelain crown is a custom-made cap that fully covers a natural tooth that has been reshaped and prepared. Crown is typically made from high-quality porcelain or porcelain-fused-to-metal materials.
Indications:
– Severely chipped tooth
– Tooth that have undergone root canal treatment
– Heavily discolored or stained tooth
– Tooth with abnormal shape
Benefits:
– Restores chewing function
– Protect the natural tooth structure
– Provide a natural aesthetic appearance
2. Dental Crown Procedure
- Examination & Consultation: Assess tooth and gum condition; discuss aesthetic and functional needs..
- X-ray/CBCT Imaging: Evaluate tooth root and jawbone structure.
- Impression & Shade Selection:
– Gently reduce 1–2 mm of tooth structure
– Take impressions
– Choose the appropriate porcelain shade. - Crown Fabrication:
– The dental technician craft the crown at a laboratory within 3–5 days. - Try-in & Adjustment:
– Try-in the crown, check the occlusion, shape, color, and make adjustments if necessary. - Permanent Placement:
– Permanently bond the crown using light-cured dental cement and polish for a natural finish
3. Post-Crown Care Instructions
- Use a soft-bristled, small-headed toothbrush for easy access
- Hold the brush at a 45° angle toward the gum line
- Brush using small, gentle circular motions, not harsh horizontal scrubbing.
- Brush each section for 10–15 seconds, total brushing time: 2 minutes
- Brush the outer (buccal), chewing (occlusal), and inner (lingual) surfaces of the teeth.
- Apply moderate pressure to avoid scratching the porcelain crown
- Use low-abrasion toothpaste (RDA ≤ 70) to protect the porcelain surface.
- Use dental floss or water flosser to clean between teeth and under the gums.
- Avoid biting on hard objects and grinding teeth (wear a night guard if necessary).
- Schedule a dental check-up every 6 months to assess crown margins and remove tartar around the porcelain crown.
