Dental examinations are usually recommended every six months, in order to detect cavities at an early stage and to allow stagnant plaque and tarter to be reoved, before it can damage the teeth and gingival tissues. Often early stages of decay and gingivitis are relatively painless.
Although large cavities can cause pain, most small to medium ones cause little or no discomfort. I find that where their teeth are concerned many people reassure themselves by thinking that if nothing hurts they have no teeth problems. Unfortunately, this is not always true. The best way to determine whether decay is present is an examination by a dentist. Radiographs help detect interproximal decay and a bright light and a dental explorer are helpful to find occlusal,buccal and lingual decay.
