According to NIDCR, National Institute of Dental and Craniofacial Research, brushing your teeth won't make the tobacco stain go away. The staining is too hard and must be scraped or scaled off by a dental hygienist or dentist. There are also more indications and "signs of a smoker" on the human body.
Hands, fingers, lips, skin and teeth are affected
The most evident and enduring signs of smoking are the tar and nicotine stains can also be found on hands, fingers, lips and on the skin in addition to the teeth. Smoking, as you might know causes premature skin aging. All of these signs also point to a cardiovascular risk among smokers. It seems like a smoker can easily be spotted by all these dark stains affecting the cardiovascular system and body.
Hair follicle DNA is affected
Another area of the body that is affected by smoking is the hair, or loss of hair, you might say. Studies indicate that smoke genotoxicants cause damage to the DNA of the hair follicle.
These studies were done in Ghana, because Ghana has no legislature to prevent smoking in public places. This secondhand smoke exposure study was done by the Environmental Health Science Department, Yale University School of Medicine in New Haven, Connecticut.
This was an observational study that had indicated a significant relationship between smoking and baldness.
Another study around that time period also indicated that the nicotine content of white hair was much less than that of black hair collected from the same subjects with grizzled hair, according to the Department of Pharmacology, Hamamatsu University School of Medicine, Japan.
It appears that hair nicotine levels among nonsmokers working in places with there are no restrictions on smoking were similar to hair nicotine levels of active smokers, according to the Department of Public Health, Wellington School of Medicine in New Zealand.

The only way for you to re-grow the thick, full hair you deserve is to attack baldness at the source of the problem. Click Here! to find out how.
Middle-aged men are more affected by cigarette smoking than by their diet
Compared with nonsmokers and independent of body mass index and age, cigarette smokers had 18% higher serum levels of DHEA, 13% higher, 5% higher cortisol, 33 % higher androstenedione, 9% higher testosterone, 8% higher SHBG and 14% higher DHT. This data suggests that serum adrenal steroid and sex hormone concentrations in middle-aged men are more influenced by cigarette smoking, age, and obesity than by dietary intake; however, serum adrenal steroids were influenced by alcohol intake, according to the Department of Epidemiology at the Harvard School of Public Health.
