Background:
It is known that tobacco is related to a broad spectrum of oral conditions and diseases, from benign to malignant. Health Professionals, becoming aware of the oral health consequences, should be able to successfully impart their knowledge to patients, in the context of personalized counseling to enhance their motivation for smoking cessation.

Objectives:
The presentation aims to provide a concise overview of the effects of smoking on oral health for all health professionals.

Methods:
For this purpose, data from PubMed, Centers for Disease Control and Prevention, World Dental Federation, Tobacco Induced Diseases, The American Academy of Oral Medicine, and Wiley Online Library were used. The search was done within three months and in the English language, with criteria of the keywords: tobacco use, dental implants, caries, periodontal disease, oral cancer, oral diseases, and nicotine. From the available bibliography, we selected 20 articles, but we only used 15.

Results:
Smoking may influence oral microbial composition, cause epigenetic alteration of oral epithelial cells, and inhibit local immune response, damaging oral tissue. The damages of soft and hard tissues can be divided into a) benign lesions such as the higher DMFT score, 80% higher risk of periodontitis and dental implants, doubled possibility of smokers being edentulous, and b) precancerous and cancerous soft tissue lesions, such as leukoplakia, which may progress to oral cancer, the 8th more common type of cancer. Smokers have a 4.65-fold increased risk of developing oral cancer. Smoking also has a negative impact on the treatment of the diseases mentioned above.

Conclusions:
Awareness of health providers is important to aid their patients to quit tobacco use. In particular, the role of the dental community is very important since half of the patients who smoke visit the dentist each year, making the dental clinic an ideal place for smoking cessation interventions.
