Cavity Checks from a Family Dentist

One of the main reasons people typically visit a family dentist is to get a cavity check. The American Dental Association states that 91% of adults in America over the age of 20 have had at least one cavity. Generally included in each six-month wellness examination, a cavity check can help both identify areas where cavities may be forming and monitor existing cavities that may be too small for a filing. Here are some things to expect during this type of appointment.

Common cavity detection methods

Unfortunately, many people wait until they have tooth pain before going to the dentist. Under these circumstances, any existing cavities are usually obvious without using any probing instruments. While certain cavities are large enough to be seen with the naked eye, others can only be identified upon closer examination using more sophisticated tools.

Probing tools

Dental professionals frequently use probing tools to poke at tooth enamel and determine whether it is hard or soft. A sickle probe is a tool used by dentists to check for cavities until more modern methods were developed. This probe made it easier for a dental professional to locate soft spots on the enamel that had been weakened by decay and worn down by erosion. A briault probe is curved, has sharp points on both ends, and is useful for locating soft spots in between the teeth. A dental hygienist may still use these probes during a cleaning to determine if further examination is needed in a specific area of the mouth.

X-rays

A cavity can be easily identified in an X-ray by a family dentist. It will show up as a dark spot in a white tooth. X-rays can pinpoint the location and depth of cavities, including those in between the teeth. Because of this, most dentists recommend having imagery taken regularly. In certain cases, especially in areas between the teeth, cavities may start to form that are not visible to the naked eye. Getting an X-ray can identify these areas so a dentist can keep a close watch on them. Although less common, cavities can also form underneath previous fillings. When this happens, the only way to see the new decay is with an X-ray.

Lasers

There are patients with tooth decay that starts out underneath the enamel instead of on the surface of the tooth. In these cases, neither probing tools or X-rays are effective at identifying the damage. Subsurface cavities can only be located with the help of lasers. During this cavity detection method, the laser that is directed at the teeth will pass through healthy enamel but reflect back off of any decay.
