Preventive, basic and major dental
Dental plans sort procedures into three classes. Preventive is cleanings, exams, routine X-rays and fluoride for children, paid in full or nearly so, with no deductible, usually twice a year. Basic is fillings, simple extractions and sometimes root canals and periodontal work, paid at a high share after a small deductible. Major is crowns, bridges, dentures and implants where covered, paid at a lower share. Which class a root canal or a crown falls into varies by carrier and is worth checking against the work you know is coming.
