A dark mark is not enough to diagnose decay, and early decay may not be easy to see. A dentist can assess the tooth surface and decide whether further investigation is appropriate.
Bring your own priorities to the appointment. Explain what has changed, what you hope to improve and which practical concerns matter to you. A photograph or an online description can help start a conversation, but it does not establish what treatment you need.
Questions for your consultation
- What has the examination found, and what still needs to be checked?
- What alternatives should I compare before choosing a treatment?
- Which parts of the plan are essential, and which are optional?
- What appointments, maintenance and review arrangements should I expect?
Make a written plan
Ask for a plan that separates the proposed care, the appointment sequence and the estimated cost. If you are travelling, discuss what happens if the findings at your first visit change that plan. Keep copies of your agreed arrangements and treatment summary.
