Short readings by Dr. Khalil on smile proportions and minimal-intervention decisions — science explained in its own language, without hype or promises.
ازدحام الأسنان: هل المشكلة جمالية فقط أم أنها تؤثر على صحة فمك؟
ازدحام الأسنان لا يؤثر دائمًا على المظهر فقط، فقد يجعل تنظيف بعض المناطق أكثر صعوبة وقد يرتبط بمشكلات في الإطباق لدى بعض الحالات. تعرف على أسباب ازدحام الأسنان، تأثيره على صحة الفم، ومتى قد يكون التقويم هو الخيار المناسب.
Read the articleهل هو الخيار المناسب لابتسامتك؟
الفينير يمكن أن يحسن شكل ولون وتناسق الأسنان، لكنه ليس الخيار المناسب للجميع. تعرف على الحالات التي قد يناسبها الفينير، وأهمية تصميم الابتسامة، وتحضير الأسنان، والبدائل المتاحة قبل اتخاذ القرار.

تبييض الأسنان قد يحسن مظهر الابتسامة، لكن النتيجة تختلف من شخص إلى آخر. تعرف على أسباب اختلاف نتائج التبييض، وأنواع التصبغات، وتأثير الحشوات والفينير، وكيفية اختيار الطريقة المناسبة للحصول على نتيجة طبيعية ومتناسقة.
Read the articleWhy Does a Veneer Last? Three conditions advertising never mentions
A veneer's lifespan is not made by ceramic alone. On enamel bonding, occlusal engineering, and the silent maintenance contract between doctor and patient.
Read the articleThe Ethics of the Minimum: why we do not touch a tooth before the map
Enamel does not grow back. On the biological cost of aesthetic decisions, and why we always order options from the least invasive upward.
Read the articleThe Engineering of a Smile: from Lombardi to Levin
Why draw an axis before touching a tooth? A reading of the proportions that moved smile beauty from personal taste to written measurement.

Glossary
The glossary is currently available in Arabic and English.
Porcelain veneer
A thin ceramic layer bonded to the tooth face to correct colour or form with minimal preparation.
Occlusion
How upper and lower teeth meet in closure and function — the foundation of any stable result.
Facial axis
The vertical reference line on which lengths and inclinations are measured before any aesthetic decision.
Smile arc
The harmony of front-teeth edges with the lower-lip curve in a smile.
Gummy smile
A wider-than-usual gum band showing on smiling; causes are measured before choosing a solution.
Minimal preparation
Removing the least possible tooth structure to reach the goal — the minimal-intervention principle.
Mock-up
A temporary try-on placed over the teeth to preview form before any final step.
Gingival levels
The gum positioning line around each tooth; its regularity frames the smile.
Incisal edge
The lower border of upper front teeth — its position is a measured decision, not taste alone.
Bonding
The chemo-mechanical bond between ceramic and enamel; its quality decides veneer longevity.
Enamel
The tooth's hard outer layer — the most reliable surface for long-term bonding.
Midline
The line between the two upper central incisors and its relation to the facial axis.
