Smoking is not only linked to lung cancer and heart disease, but it also damages the state of the mouth. Smoking increases the risks of tooth loss, but more importantly, it is the main cause of throat and oral cancers. In fact, smoking sets off 75% of all cancers of the mouth.

Smoking and overall health

Here are some facts of how smoking affects someone’s health:

  • More than 90% of all regular smokers began using tobacco at or before age 18.
  • People who smoke are more likely to have sinusitis.

  • The risk of tooth loss in smokers is twice more than in non-smokers.
  • Smoking is the main cause of throat and oral cancers.
  • Smoking increases periodontal disease (gum disease). In fact, according to the Journal of Periodontology, smokers are about four times more likely than people who have never smoked, to have advanced periodontal disease.
  • Smoking can cause inflammation of the salivary glands.
  • Smoking delays healing after tooth extraction and can lead to a temporary and painful condition known as dry socket.
  • Smokers have less success with periodontal treatments and dental implants.

  • The loss of taste and smell can be caused by smoking and chewing tobacco.
  • Smoking stains teeth reducing the aesthetics of a smile.
  • Tobacco use can cause black hairy tongue, which refers to growths on the tongue, making it look hairy and turning it yellow, green, brown or black.
  • Smoking might produce constant plaque and tartar build up.

Recommendations for smokers

To say “stop smoking” is an easier thing said than done. Nicotine addiction can be very strong and hard to lose, that is why tobacco companies are so successful with their products. But to stop smoking is also the most effective way to eliminate all the hazards that tobacco can cause, not only to oral health, but also to increase the chances of living a long and healthy life with the people we love.

Here some tips for smokers concerning their oral health:

  • Although it’s easier said than done, stop smoking or stop chewing tobacco!
  • Have regular checkups with the dentist in order to verify the state of the gums and make sure no oral cancer is developing.
  • Maintain a thorough oral hygiene plan by regularly brushing, flossing, using mouthwash and tongue cleaner, and by having regular professional cleanings at the dentist’s office.
  • Learn how to do an oral cancer self examination:
    • Check for any sores around the face, neck or mouth that do not heal within two weeks.
    • Check for frequent bleeding in the mouth.
    • Check for white, red or dark patches on the cheeks, palate, tongue, or under the tongue; if such lesions do not disappear after two weeks, have them checked by a dentist.
    • Check for swellings, lumps or bumps on the lips, gums, or other areas in the mouth.
    • Notice any numbness, pain or loss of feeling in any area of the mouth.

It is evoked that the fresh clean feeling a person feels in the mouth after brushing and flossing may restrain the urge of smoking. Ironically, these simple tips also help to prevent periodontal diseases.
