Does smoking affect your teeth?

It has recently become widely known that smoking is bad for overall health, but I am curious if it also has a direct impact on teeth. I have heard that long-term smoking causes teeth to turn yellow, but does it actually make one more susceptible to problems like cavities or gum disease? I am also concerned that smoking affects tooth roots or gum bone, potentially causing teeth to weaken or fall out sooner. I try to brush my teeth thoroughly and get regular dental checkups, but I worry that my smoking habit might render these efforts meaningless. If anyone has any experience or information regarding the actual connection between smoking and dental health, I would be very grateful to share it.
