Practical decision guide

General dental decisions should preserve healthy tooth structure whenever possible. A good plan moves from diagnosis to the least-invasive durable treatment, then to prevention so the same problem does not repeat.

Check this first

• X-rays, pulp vitality, crack lines, gum pocketing, bite contacts, and how much natural tooth remains.
• Whether the problem is active disease, old restoration failure, trauma, wear, or a cosmetic concern.
• Whether a filling, onlay, crown, root canal, extraction, or monitoring is the right next step.

When to book sooner

• Pain wakes you at night, lingers after hot or cold, hurts on biting, or comes with swelling.
• A crown or filling falls out, a tooth cracks, or a sharp edge is cutting the tongue or cheek.
• You notice pus, fever, spreading swelling, or difficulty opening, swallowing, or breathing.

Questions to ask at the appointment

• What is the diagnosis, and what evidence supports it on the x-ray or clinical exam?
• What is the smallest treatment that solves the problem predictably?
• What failure signs should I watch for after treatment?

Dubai patient note

If insurance is involved, ask whether pre-approval is required, what codes will be submitted, and what alternatives are clinically acceptable if coverage is limited.
