The Dentist Roulette.. How often do YOU change dentists?

Some people spend a lot of time looking for the right doctor that they are comfortable with. That got me thinking, how long do people look for a dentist that they are comfortable with. I did some online research. I was astonished by results.

It turns out that almost 43% of people rarely visit the same dentist more than twice. 

If you have a problem with you dentist, then I can see reason for changing a dentist. Other than that, what would be the point of going to a new dentist each time you need work done? I am curious to hear your thoughts on this.

If you are one that plays "dentist roulette", let me fill you in a secret:

YOU ARE SPENDING MORE MONEY: Think about it. Then dentist you went to before has already done an examination, has your past x-rays on file, has a treatment plan created and knows the work that they did on your teeth. Every time you change dentists you have to go through that again. The need to take more x-rays so they can see what the status of your teeth are when you walk in. They need to do a exam to see what has been done before and create a new treatment plan. Not to mention the paperwork that is needed on your first visit. 

Okay, I have given you my point of view, I am interested to hear yours!
