I know they replace their teeth with the front row dropping out and a new row popping up behind.

They have about 3000 teeth, arranged in several rows. The first two rows of teeth are used for grabbing and cutting prey, while the teeth in the last rows rotate into place when front teeth are broken, worn down, or fall out. The teeth are triangularly shaped with serrations on the edges.
Great whites, like many other sharks, have rows of teeth behind the main ones, allowing any that break off to be rapidly replaced. Their teeth are unattached to the jaw and are retractable, like a cat's claws, moving into place when the jaw is opened. Their teeth also rotate on their own axis (outward when the jaw is opened, inward when closed). The teeth are linked to pressure and tensor-sensing nerve cells. This arrangement seems to give their teeth high tactile sensitivity. A great white's teeth are serrated and when the shark bites it will shake its head side to side and the teeth will act as a saw and tear off large chunks of flesh. Great whites often swallow their own broken off teeth along with chunks of their prey's flesh. These teeth frequently cause damage to the great white's digestive tract, often resulting in death from infection and blood loss.

The great white shark has 3,000 teeth at any one time. They are triangular, serrated (saw-edged), razor-sharp, and up to 3 inches (7.5 cm) long.
The teeth are located in rows which rotate into use as needed. The first two rows are used in obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth that rotate into place.

The Great White Shark (Carharodon carcharias) is a shallow water shark who likes to travel. He has even starred in a few movies, and is famous for his smile. That's because he has plenty of very big white teeth. His teeth are evenly serrated, the better to eat anything else with. The Great White is white on the bottom and a sort of charcoal color on top, with big jet-black eyes and a crescent-shaped tail fin. He grows up to be about 25 feet long!
The Great White Shark has serrated, wedge-shaped teeth for cutting. Small conical teeth, like the Nurse Shark's are for crushing shells of crabs and mollusks found on the bottom of the ocean.
A rough formula for calculating the size of a shark, using its teeth, is to measure the length of one side of the tooth in inches, then multiply by ten to calculate the total length of the shark in feet. This estimate only applies to large triangular-shaped teeth, but if you ever find one you will be able to imagine just how big the shark was that it came from. Shark Anatomy

There's no exact answer, except maybe infinite because great white sharks grow new rows of teeth after another and another.

LOL....
When I saw your question, I just couldn't resist answering, but I don't mean to sound condescending or rude but does it matter? lol.... All I know is, if I'm ever swimming in the ocean and I see a great white shark or any kind of shark for that matter..... nobody will stop to ask me how many teeth the shark has....lol They'll want to know how the hell I ran on top of the water all the way to shore... lmao......
Sorry dude.... I live in Hawaii and sharks are a serious issue but I just couldn't help myself. I hope I did not offend you but when I read your question.... I just started laughing because I pictured myself running on water.... lol.
Peace.
