Vaping negatively affects your oral health by causing dry mouth, weakening enamel, increasing bacterial growth, and raising the risk of gum disease, tooth decay, and oral lesions. It can also interfere with cosmetic dental treatments such as veneers, teeth whitening and orthodontics by slowing healing, staining teeth and compromising treatment results.
Vaping and tobacco use continue to grow in popularity, often viewed as an alternative to smoking. However, its impact on oral health is far from harmless. Research shows that the effects of vaping reach deep into the oral cavity, influencing gum health, enamel strength, saliva flow, dental caries risk, and the success of cosmetic dental treatments.
This comprehensive guide from The Veneer Studio explains how vaping affects teeth, gums, and overall oral health, how it compares to smoking, and what you can do to protect your smile.
Vaping delivers heated aerosol containing nicotine, flavourings and chemicals. These substances interact with the oral tissues in the same environment where saliva, bacteria and enamel work together to protect your teeth and gums.
Both vaping and smoking create an increased risk of oral diseases by:
• Drying the mouth
• Irritating the gums
• Weakening enamel
• Encouraging plaque accumulation
• Altering the oral microbiome
• Slowing healing after dental treatment
Although vaping is often seen as an alternative to smoking, e-cigarette use still produces adverse effects similar to tobacco smoking.
Vaping may lead to several oral health problems, including:
• Higher risk of gum disease
• Gingivitis
• Tooth decay
• Dental caries
• Cavities
• Stained teeth
• Xerostomia (dry mouth)
• Oral mucosal lesions
• Oral lesions
• Slowed healing
• Tooth loss
• Decreased taste
• Increased bacterial activity
Recent studies, including findings from national health and nutrition examination surveys and BMC Oral Health, highlight that the oral microbiome of electronic cigarette users shifts in ways that increase inflammation, plaque retention, and the growth of Streptococcus mutans, which is strongly linked to dental caries.
Dry mouth is one of the most common vaping symptoms. Reduced saliva increases the risk of dental caries, gum irritation, and bad breath. Chemicals in vaping liquid can cause dry mouth by disrupting the function of the salivary glands.
Acidity and heat soften enamel. Once enamel erodes, it cannot regenerate. This increases sensitivity, discolouration, and the risk of cavities.
The sticky aerosol from vaping clings to tooth surfaces, promoting plaque formation and increased exposure to bacteria. This increases the risk of developing oral diseases and periodontal problems.
Changes to the oral tissues and microbiome can reduce taste perception. Many long-term vapers report diminished flavour sensitivity.
Nicotine and oral health are closely linked. Nicotine reduces blood flow to the gums, which affects:
• Tissue healing
• Gum attachment
• Inflammation levels
• Periodontal health
Vaping can increase the risk of oral health complications similar to cigarettes because nicotine constricts blood vessels in the gums.
The development of oral disease often begins with:
• Gingivitis
• Bleeding gums
• Swelling
• Early periodontal pocketing
Vaping and smoking increase gum disease risk by weakening the gum tissue and increasing inflammation.
Untreated gum disease is one of the leading causes of tooth loss, along with other health effects. Regular dental visits, early detection and strong oral hygiene can help prevent long-term periodontal problems. One of the most common impacts of vaping is deteriorating gum disease.
Most patients notice improvements in colour, inflammation and healing once they reduce or stop nicotine use. Blood flow increases, and the oral environment stabilises, strengthening the teeth and gums over time.
Many vape liquids contain sweeteners and acidic flavours. These contribute to:
• Dental caries
• Cavities
• Enamel weakening
• Increased bacteria growth
There is a growing association between vaping and untreated caries, as shown in a cross-sectional study of national health data.
• Sticky aerosol coats teeth
• Saliva decreases
• Acids soften enamel
• Bacteria multiply faster
• Streptococcus mutans colonises more easily
Vaping can cause rapid cavity formation, especially in younger users.
Vaping may irritate the oral mucosa and oral tissues, causing:
• Red patches
• Discomfort
• Sensitivity
• Oral mucosal lesions
Chemical ingredients can trigger inflammation and oral changes that affect the overall oral health.
The long-term effects of vaping on oral cancer are still being studied, but both smoking and vaping expose the mouth to carcinogenic substances.
Symptoms of mouth cancer include:
• Persistent sores
• Lumps
• Difficulty swallowing
• Unexplained bleeding
• Changes in the oral environment
The health impact of electronic cigarette aerosol remains a concern in oral medicine and oral and maxillofacial fields.
Yes. The effects of vaping influence nearly all cosmetic treatments. Below are common treatments and how vaping may affect their effectiveness.
Porcelain does not easily stain, but the natural tooth structure around a veneer can stain from nicotine.
Vaping may also increase:
• Gum recession at veneer margins
• Sensitivity
• Enamel weakening under veneers
These changes affect both the appearance and longevity of veneers.
Whitening results fade faster in people who vape. Nicotine and flavouring chemicals can:
• Causes yellowing
• Neutralise whitening results
• Increase enamel sensitivity
Those who vape often require more frequent touch-ups.
Can you still achieve successful orthodontic treatment while vaping?
Yes, but with challenges. Vaping during orthodontic treatment can:
• Increase plaque around brackets
• Slow tooth movement due to inflammation
• Compromise gum health
• Affect appliance bonding strength
Orthodontic treatment is most successful in a healthy oral environment. Reducing vaping habits helps shorten treatment time and improve gum stability.
Any procedure that relies on strong enamel or healthy gums can be affected by vaping on oral health. This includes bonding, whitening, veneers, orthodontics and even future restorative work.
Studies show that the effects of electronic cigarettes may include:
• Increased plaque
• Oral microbiome disruption
• Gingival inflammation
• Dental caries risk
• Oral mucosal irritation
There is a reported vaping link to increased risk of oral disease, according to recent health and nutrition examination survey data.
The public health consequences of e-cigarettes remain a concern, and the health harms of vaping are becoming more widely recognised by the Australian Dental Association and other dental associations worldwide.
• Nicotine reduces blood flow
• Aerosol residue increases acidity
• Chemicals weaken enamel
• Heat irritates soft tissues
• Flavours promote harmful bacteria
• Saliva flow decreases
These factors combine to increase the risk of oral health problems.
Lower nicotine levels reduce irritation and improve gum health.
Even small reductions can improve periodontal health.
Hydration helps prevent dry mouth and strengthens saliva’s protective function.
Brush twice daily, floss and use fluoride toothpaste to support overall oral health.
Professional care helps detect early damage and prevent the long-term effects of vaping.
• Drink water after vaping
• Choose low-sugar vape liquids
• Minimise frequency
• Use sugar-free gum to stimulate saliva
• See your dentist regularly
Dental clinics, oral medicine specialists and support services through the Department of Health can help manage symptoms, treat existing issues and support vaping reduction strategies.
