      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Professional teeth whitening results last 1–3 years depending on diet and habits. Coffee, tea, red wine, and tobacco accelerate staining. Touch-up treatments every 6–12 months maintain results. Dental veneers offer permanent color change."

      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Whitening agents only work on natural tooth enamel. Crowns, veneers, and bonding do not respond to whitening. If you whiten before getting crowns or veneers, your dentist can match them to your new shade."

      "name": "Is professional teeth whitening safe for sensitive teeth?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, with modifications. Dentists can use lower-concentration peroxide and custom trays that minimize gum contact. Desensitizing gel before or after treatment reduces sensitivity. Over-the-counter products often cause more sensitivity than professional treatment."
