Dental plans will usually cover a portion of your costs on different types of dental procedures. Some plans focus more on preventative and basic dental care, but offer less coverage on major dental procedures. It's important to understand what's best for your dental health. If you routinely need a root canal or get cavities, you'll want a plan that provides better coverage on those types of procedures. In contrast, if you have relatively healthy teeth then you might not need to pay for the extra coverage.
Most full coverage dental insurance plans will cover two preventive maintenance visits per year without requiring a deductible payment. Most require a $50 deductible per person, per year to help cover costs beyond your preventive exams. If you need work done, most plans will cover a part of the costs. We looked at root canals specifically and found that the majority of dental plans will cover about half the cost, which may not seem like a lot, but paying half is better than paying upfront for an $800 root canal. However, keep in mind that most insurance policies, depending on your plan, top out at about $1000 to $1500 per year. Using conservative estimates that might be one or two root canals. If you need extensive work done you might have to pay the remaining amount out of pocket.
