Whilst most of us are aware of the effects of smoking on our general health causing many medical problems that can sometimes be fatal, many people may not be aware of the effect that smoking can have their oral health by affecting their teeth, gums and mouth.
What effects can smoking have?
- Stained teeth. Smoking exposes your teeth to both tobacco and nicotine, which can have the effect of staining or yellowing of the teeth. Heavy and long-term smokers often find that their teeth are almost brown after years of smoking. Brushing several times a day with a whitening toothpaste can help prevent staining and may help to reduce existing stains. There are also over-the-counter products, such as whitening gels and strips, that can be applied to help remove stains. Depending on how severe the staining is, professional teeth whitening may be needed.
- Increased build-up of plaque and tartar on the teeth. Smokers tend to have more tartar on their teeth than non-smokers. This is because the nicotine in the tobacco reduces the production of saliva in the mouth thereby making it easier for bacteria and tartar to build up.
- Whitening of the soft tissue in the mouth. A white patch can develop on the roof or other areas of the mouth in smokers and is known as smoker’s keratosis. Being painless, you might not even be aware it is there and is often discovered during a check-up with your dentist. Whilst smoker’s keratosis is not dangerous and needs no treatment, it can mimic the appearance of leukoplakia, which is potentially cancerous and requires treatment, and any white patches should be examined by your dentist.
- Gum or periodontal disease. Smoking can lower your immune system, which makes you more susceptible to gum disease, an infection that affects the gum line. It can develop when bacteria and tartar build up below or above the gums, more common in smokers, resulting in inflammation. Smoking can also reduce the amount of oxygen in the bloodstream and blood flow to the gums affecting the healing of infected gums. This infection, if not treated, can damage the bone and structures that hold the tooth to the gum resulting in loosening of the teeth and potential tooth loss.
- Mouth cancer. Smoking is one of the main risk factors in developing mouth cancer. For people who smoke and drink alcohol the risk is considerably higher than for those who just do one or the other. Mouth cancer in people who smoke is most likely to occur on the side of the tongue, the floor of the mouth and lips, but it can also happen in other areas of the mouth such as the cheeks, the roof of the mouth and gums. It is important that if you notice any changes in your mouth you contact your dentist or doctor straight away, as if diagnosed early it can be treated before it spreads to other parts of your body.
- Bad Breath. Bad breath can be an unwelcome side effect of smoking. Smoking causes your mouth to dry out due to a decrease in saliva. Saliva acts as a natural wash for your mouth and lack of it can cause the cigarette smell to linger. Being in the early stages of gum disease can also cause bad breath. Smoke that remains in the lungs is breathed out when you exhale adding to the problem. To help resolve the issue, you should be diligent with your twice daily brushing and daily flossing and drink plenty of water. An antibacterial mouthwash may help, or you could try chewing sugarless gum or sucking a peppermint. A regular professional dental clean with remove any build-up of plaque and tartar on your teeth reducing the risk of gum disease.
- Slow healing after dental treatments and surgery. Because of the effect of smoking on the immune system, healing can be delayed following tooth extractions and oral or gum surgery and can result in increased pain. Slow healing following the removal of a tooth can cause dry socket, which is very painful.
What about vaping?
Because e-cigarettes contain no tobacco and do not produce smoke, many believe that them to be less harmful and a good way to ultimately quit smoking. Although less than regular cigarettes, they still contain other cancer-causing chemicals and heavy metals and the vapour they produce contains nicotine, even in those labelled as nicotine free. This can result in inflammation and dryness in the mouth that can cause damage to the gums and lead to gum disease and other problems with your oral health. If you vape, you should ensure you maintain good oral hygiene, drink plenty of water and visit your dentist regularly.
How will quitting smoking help?
No matter how long you have been a smoker, quitting will have a big impact on the health of your teeth and gums. Your gums will be allowed time to recover and become stronger and your immune system will respond better. Less bad bacteria in your mouth will reduce the build-up of plaque and tartar and the chances of gum disease, bad breath and tooth loss. Eventually your risk of developing gum disease will be the same as non-smokers and also your chances of developing mouth cancer will be significantly lower. A visit to your dentist for a professional scale and clean should help to speed up your recovery.
What can I do if I can’t quit smoking?
If you are having trouble quitting smoking, there are some things that you can do to reduce your risk of developing problems with your teeth and gums.
- Reducing the amount you smoke can help lower your risk
- Maintain good oral hygiene by brushing twice a day and flossing daily
- Hydrate your mouth by drinking plenty of water
- Stimulate saliva flow by chewing on sugar-free gum.
- Attend regular check-ups with your dentist to ensure any problems are found early
- Have a regular professional scale and clean to remove any plaque and tartar build-up to help protect your gums and prevent staining.
How can my dentist help?

They are also able to give you guidance on how to quit smoking and refer you to organisations and groups that can help you. At your regular visits, your dentist will be able to monitor your oral health and its recovery from the effects of smoking.
