What happens to teeth when you smoke?

Smoking is lethal for general health as well as disastrous for oral health. The effects manifest in various ways that affect the appearance of your smile. According to a study, use of tobacco causes nearly 9 million deaths globally (almost 15% of deaths worldwide). Studies also suggest oral cancer is quite common nowadays and one of its main causes is heavy smoking.

Following are the typical signs of smoking habits on teeth:

  • Gum Recession
  • Yellow Teeth
  • Bad Breath
  • Sensitivity
  • Gum disease
  • Tooth Loss
  • Recurring Tooth Infections
  • Loose Teeth

Gum Recession

The damaging effects of smoking tobacco usually first show on the gums. In extreme cases, the gums recede and lose their elasticity. This also means the alveolar bone is shrinking and losing volume so it doubles the risk of tooth loss. It endangers the entire structure of the tooth. It also exposes the tooth to dental carries and may create further bigger issues such as periodontal disease. The good news is that you can reverse this cycle of damage just by quitting smoking. 

Yellow teeth

The biggest downside of smoking is its effect on the physical appearance of a smile. Tobacco is one of the biggest causes of stained teeth and discoloration of teeth. A study also shows current smokers show a higher prevalence of yellow teeth and discoloration problems. Yellow teeth lead to lack of self-confidence that can also cause self-image issues. The best thing one can do is to stay away from smoking to avoid permanent damage to teeth. 

Bad Breath

A common trait among smokers is bad breath. Nicotine and tartar build-up causes the mouth to emit a bad odor, also known as Halitosis. In social settings, this is a huge red flag and people around you may avoid interacting with you. A study shows smoking increases the risk of Halitosis by causing hyposalivation. A dry mouth or hyposalivation means decreased salivary flow in the mouth. 


Among other risk factors, smoking also doubles the risk of enamel erosion or enamel thinning. Enamel is a protective layer on top of teeth that protects them from toxins. Thinning of the enamel exposes the inner layer of teeth called dentin. It makes teeth sensitive to extreme temperatures and you may feel a sharp recurring pain. To avoid this, cut down on smoking habits or simply quit to improve your oral health. 

Gum disease

Smoking affects the gums the most because it comprises of soft tissue. The impact of tobacco is faster and bigger on the gum area. In extreme cases, current smokers develop severe gum diseases such as gingivitis. Bleeding and swelling of gums are classic symptoms of this disease. Moreover, smoking gives you a gummy smile that dims down the beauty of your smile. It also doubles the risk of tooth loss if you do not seek treatment for it.

Tooth loss

Smoking has a domino damaging effect on natural teeth. The bacterial build up in the mouth overtime causes many issues such as dental caries, gum diseases etc. If you smoke and avoid going to the dentist, your oral health may decline faster than you know. If dental caries and gum issues go untreated, the tooth gets weaker by the day. Delay in seeking treatment leads to tooth loss and other bigger complications. A study also suggests there is a relationship between cigarette smoking and tooth loss. It further shows smokers are at a higher risk of experiencing tooth loss. 

Recurring Tooth Infections

If you are a current smoker and neglect your oral health, you may be more prone to tooth infections. Recurring infections result from accumulation of tobacco and tar build-up on teeth. Tooth infections occur usually due to cavities or dental caries, periodontal disease or gum infections. The only way to avoid recurring infections is regular cleaning, oral hygiene and smoking cessation. 

Loose teeth

Cigarette Smoking has many adverse effects and one of them is periodontal disease that affects the gums. This gum disease over time shrinks the alveolar bone. Alveolar bone loss makes natural teeth loose. It raises the risk of losing teeth and many other serious complications and oral diseases. The earlier you seek periodontal treatment, higher are the chances of saving your teeth. 

Does smoking make a tooth infection worse?

Tooth infections get worse if you smoke because it slows down the healing process. Smoking while you heal from a tooth infection can also cause a dental abscess. An abscess is a collection of pus at the root of the tooth that creates further complications. Thus, we suggest you to stay away from smoking if you want to heal from an infection without any complications. 

Does smoking affect teeth implants?

Yes smoking can lead to implant failure, especially if you just got them. Smoking makes healing from surgical procedures difficult because it suppresses your immune system. Moreover, inhaling nicotine restricts blood flow to the surgical site that can lead to implant failure. Thus, we advise you to strictly avoid smoking for safe implant placement and post-surgery healing. In extreme cases and for heavy smokers, dentists suggest bone grafts to give a stronger grip and support to implants.

Can you vape after wisdom teeth removal?

We do not recommend it because nicotine can cause dry socket. Nicotine restricts blood flow to the surgical site and causes hypo salivation. Both can slow down the healing process. 

Thus, if you are still thinking if you can vape after wisdom teeth removal, our answer is a strict NO! Anything that can cause complications and adverse health effects during this time is worth staying away from. Heavy smokers must refrain from vaping and all sorts of tobacco products to speed up the healing process.
