Craze lines are the fine, vertical, hairline lines you notice on front teeth in certain light: superficial marks in the enamel from decades of normal biting, temperature swings, or old habits like nail-biting. They're extremely common, usually harmless, and mostly an appearance question.
When they bother someone, treatment is conservative: professional polishing, superficial resin to fill and blend the lines, and whitening if stain has settled into them. A dentist will also confirm they're truly surface lines. An actual crack is a different conversation, and telling them apart is exactly what the exam is for.
The honest limits of this preview
Superficial enamel lines only. Deeper cracks need an exam, which a preview cannot replace. A preview can't see bone, bite, gum health or anything beneath the surface. Only a clinical exam can. Treat it as a conversation starter for your dentist, never as a promised result.
Worth asking your dentist
- Are these superficial craze lines or a crack that needs attention?
- Would polishing and resin blend mine, or has stain settled in too deeply?
- Is anything in my bite or habits still adding new lines?
