Why oh WHY would anyone want to open up a practice in a saturated market 😕 The notion is simply ridiculous. Anyone with any business sense would know that there are so many untapped markets in dentistry, I find it hard to understand why so many dentists set up shop in an area that already has plenty of dentists, when there are so many areas that have a shortage!!??. Thats like me buying a Pizza Hut franchise and setting it up right down the street from another one. Sure, I'll probably just scrape by, but with a little research I could have set up somehwere alot more profitable and gained first mover advantage by being the only one in the area.
So, to anwer your question, YES it is common to struggle in a situation like this. An understanding of elementary economics will help explain it: SUPPLY VS DEMAND!!! When supply is greater than demand, intense competion will brew amongst the suppliers (dentists in this simple scenerio)
