There is also no tax penalty if your children do not have dental insurance. Some dental plans may also begin paying for periodontal work, bridges and dentures. The problem with not having dental insurance is that dental care can be very expensive when critical dental problems increase, such as periodontal disorder or significant enamel decay. More than a hundred Americans don't go to the dentist because they can't afford it, so they end up broke, start having difficulties, and start developing pain. Ultimately, it might be less expensive to get regular dental care and avoid bigger, more serious problems in the long run. (Berkeley, February 2016). Dentists recommend going to the dentist regularly because even if you brush your teeth frequently, you can still create plaque and tartar buildup if you don't visit a dentist. A dental specialist will perform a thorough cleaning of the teeth which will expel plaque.
