If you are running the heat and it lowers the temp back down, I don't think it's just the gauge/sensor. Make sure both fans come on, your coolant is at a safe mixture, replace your thermostat, etc. Most likely it's your thermostat.

 

well is it dangerous to drive if the thermostat is knocked off.. or somethin

 

Have you changed your coolant lately? If you haven't, now is a good time to change the coolant and the thermostat. And you can't knock the thermostat off LOL. Overheating the engine is dangerous, DON'T DO IT!!!
