The second part of your initial dental appointment will often include X-rays. X-rays use a low level of radiation that helps to capture images of the inside of your teeth.
These images are helpful in determining any problems that aren’t visible to the naked eye. X-rays can aid your dentist in diagnosing cavities, tooth decay or impacted teeth.
X-rays are typically performed at your first appointment and again when your dentist feels that you need them. Some factors that influence the frequency of imaging include:
Current oral health
History of gum disease
Symptoms of oral disease
Children often receive more X-rays than adults due to their rapid growth and to make sure that their permanent teeth are developing appropriately.
