During a dental exam, your dentist will ask you about sensitivity and pain in your teeth. The dentist examines your teeth and mouth visually and uses instruments to put pressure on the teeth, checking for soft spots, which are a sign of tooth decay and cavities.

During a dental exam, your dentist will do a thorough screening of your mouth. He/she is checking your oral health and for any signs of problems. It's also possible that your dentist may suggest x-rays to see the roots and other parts of the teeth not visible by eye. In inspecting your mouth, your dentist can tell if you have any cavities, decay or early warning signs.

During a dental examination the dentist visually examines the teeth and checks them with an instrument to see if there are any “soft” decayed areas on the various tooth surfaces. Radiographs (x-rays) may also be used to aid the diagnosis and evaluate areas not readily visible. In addition, laser detection devices may be used, along with transillumination.
