We generally recommend a full mouth x-ray (OPG) once every 5 years. This shows teeth, jaw and sinuses, and is useful for detecting nasty little surprises before any symptoms develop. OPG x-rays are also often required to check wisdom teeth. Smaller bitewing x-rays are recommended every 2 years to detect decay between the teeth.
Your dentist will discuss any concerns you may have, and recommend options for your treatment. You will receive a written treatment plan if you require further treatment.
If you are in a health fund we can (depending on the fund) obtain an estimation of the benefit you will receive for the required treatment.
