A dental plan may limit the number of times it will pay for a certain treatment. But some patients may need a treatment more often to maintain good oral health. For example, one plan may cover dental wellness or gum therapy visits twice a year, while another allows four times a year. If a patient needs a dental wellness or gum care visit four times a year, but their plan only covers cleanings or gum care twice a year, the other two would be out-of-pocket. It’s important to make treatment decisions based on what’s best for your health, not just by what is covered in your plan.
