How dental x-rays help improve your oral health

Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth so an X-ray examination can reveal important additional information:

For example, X-rays can help show:
– Small areas of decay between the teeth or below existing fillings
– Infections in the bone
– Gum disease
– Abscesses or cysts
– Developmental abnormalities
– Some types of tumors

The way they work is that more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums). This creates an image called a radiograph.

Tooth decay, infections and signs of gum disease appear darker because of more X-ray penetration. The interpretation of these radiographs allows the dentist to safely and accurately detect hidden abnormalities.

The frequency of X-rays (radiographs) will depend on your specific health needs.

Your dentist will review your history, examine your mouth and decide whether you need radiographs and what type.

When you are a new patient, the dentist may recommend radiographs to establish how the hidden areas of your mouth currently look to help identify changes that occur later.

X-rays can help identify and treat dental problems at an early stage and so can save time, money and unnecessary discomfort.

How sedation and general anesthesia can make your visit to the dentist easier

While local anesthetics are often used in dental treatment, there is sometimes a need for anti-anxiety agents – such as nitrous oxide – or sedatives to help people relax during dental visits.

Dentists may use these agents to induce “minimal or moderate sedation”.

In this case, the patient reaches a relaxed state during treatment but can respond to speech or touch.

Sedatives can be administered before, during or after dental procedures by mouth, inhalation or injection.

More complex treatments may require drugs that can induce “deep sedation”.

This reduces consciousness and causes a loss of feeling which helps to reduce both pain and anxiety.

Sometimes patients undergo “general anesthesia” where the drugs lead to a temporary loss of consciousness.

A dentist may recommend deep sedation or general anesthesia for certain procedures with children or with adults who have severe anxiety or for people who have difficulty controlling their movements.

While these techniques to control pain and anxiety are used to treat tens of millions of patients safely every year, its important that you let your dentist know anything that might affect your ability to benefit from them for example, tell them about any illnesses or health conditions, whether you are taking any medications and if you’ve had any problems with allergic reactions to medications.
