Once you purchase a dental insurance plan and start paying your premiums, most preventive care like cleanings and check-ups are covered immediately. For more serious procedures, after you meet your deductible, you’ll only be responsible to pay your percentage of the cost. And we’ll pay the rest. Also, some dental plans have an out-of-pocket maximum to protect you from high costs throughout the year. On some plans, if you reach this maximum, we’ll pay the full cost of any additional care until your annual maximum benefit is met.
