Your OPG shows that you have several teeth with existing fillings and at least one tooth that has already undergone root canal treatment. Some teeth also appear to have significant restorations. However, an OPG alone cannot accurately tell which teeth currently need RCT or crowns. This depends on the condition of each tooth, the depth of decay, symptoms and clinical examination.
Next Steps
Please visit a dentist for a complete examination of all the teeth. Teeth with deep decay, pain or previous RCT may need individual dental X-rays and vitality tests. A crown/cap is recommended only when a tooth has lost enough structure that it needs additional protection; not every filled or root-canal-treated tooth automatically needs a crown.
Your dentist can then make a tooth-by-tooth treatment plan and tell you exactly which teeth need fillings, RCT, crowns or extraction.
Health Tips
Don’t undergo multiple RCTs or extractions based only on an OPG. If a particular tooth is painful or has deep decay, a small intraoral X-ray (IOPA) is usually more useful for deciding its treatment. Regular dental check-ups and treating cavities early can also help prevent the need for RCTs and crowns.
