The practice guidelines Treatment of tobacco dependence are drawn up by collaboration of all medical and paramedical professional associations and aim at assisting patients who would like to quit smoking. The dental team has a barrier-free opportunity to discuss smoking habits. The relation between smoking and oral health is quite obvious. Dental practitioners should ask about smoking habits regularly and smokers should be advised at least once a year to stop smoking. More intensive strategies for treatment of tobacco addiction in dental settings will be developed in the near future.
