There are three things, I would say. One would be the cost to train and the cost to run a practice. The cost to train is expensive and the cost to run a practice is expensive. We run kind of mini-hospitals, if you will, as a dentist. The same procedures are going on and the same sterilization. We have a well-trained and costly workforce. So I think that is one area of barriers.
I think a lack of maybe a common set of guidelines across the country in long-term care facilities would be a second, and a third would be a lack of general education around the need for oral health care. Listed as probably the number one reason why people don't attend a dentist is that they don't feel they have a problem.
