I’ve been told I need x-rays at the dental office, but I refused them. Why do they need x-rays, anyway?
X-rays are an important part of diagnosing problems in your mouth because they can show problems the dentist can’t see. There are many conditions that can be seen on an x-ray before they can be seen in the mouth, including decay, silent abscesses, bone loss and some tumors.
An x-ray allows the dentist to see decay in between the teeth, so that cavities can be prevented or caught before they get very large. X-rays can also pick up inflammation around the tooth root, which can signal a silent abscess. This allows the dentist to treat the problem before it hurts, does more damage or makes you sick.
