Why are Radiographs (X-rays) necessary
They are necessary for a variety of reasons:
For decay detection
During an examination, decay in a tooth can be seen if it is in an area that is visible in the mouth. Often, however, the decay between teeth or in areas where it cannot be easily visualised with the naked eye and hence remain undetected. The following images illustrate how taking a radiograph allows detection of decay otherwise not visible to the naked eye.
For root canal treatment
During root canal treatment, radiographs are an absolute necessity as the dentist is operating inside the tooth within the root system.
For pre-assessement before major dental treatment such as:
- Orthodontics
- Implant placement
- Crown and bridge work
Prior to extraction of teeth
Radiographs show the hidden root structure of a tooth and also its position relative to other teeth and other anatomical structures.
For general diagnosis of pathology and gum disease
Pain in the oro-facial region is often dentally related. Radiographs can be helpful in confirming the diagnosis. Simple visual examination might not provide enough information to allow the dentist to reach a definite diagnosis.
Radiographs also allow assessment of gum disease severity.
How often should radiographs be taken?
The recommendations are:
1. For decay assessment:
If it is your first visit at the dentist and you have had a lot of fillings in the past or decay is detected in your teeth, radiographs are recommended.
If it is a recall visit and you have had decay in the past and considered high risk of recurring decay, radiographs are recommended at 6-18 months interval for adults and 6-12 months interval for children of up to 11 years of age.
If it is a recall visit and you have not had fillings and is considered at low risk of decay, radiographs are recommended at 24- 36 months interval for adults and 12-24 months interval for children.
2. For gum disease monitoring:
When gum disease is present, specific radiographs a required to assess its severity atdifferent intervals depending on the case to determine whether there is progression or stabilisation of the disease. The frequency is decided by the dentist based on clinical judgement.
3. For post-treatment monitoring:
In cases where a patient has received more complex treatment like implants, root canal treatment or crown and bridge work, radiographs might be necessary to ensure the restoration or treatment site is being maintained in good health. Again, frequency is determined by clinical judgement.
