Vaping has gained popularity in many parts of the world – especially among teens and young adults – but in Singapore, it is important to know: vaping is illegal.
Still, with growing global exposure on social media and among peers, many are curious about its effects. And while it is often marketed as “safer than smoking”, research shows that vaping is not safe – especially for your mouth. Let’s break down how vaping impacts your oral health, and why it is something you should steer clear of.
What Is Vaping?
Vaping involves inhaling an aerosol produced by an e-cigarette or similar device. The vapour typically contains nicotine, flavourings, and other chemicals such as propylene glycol, formaldehyde and benzene – which do not just harm your lungs.
How Vaping Affects Your Oral Health
1. Dry Mouth (Xerostomia)
Propylene glycol in vapes can significantly reduce saliva production, making it harder for your mouth to naturally clean itself. This can lead to:
- Increased cavities
- Greater risk of gum disease
2. Gum Disease & Inflammation
Nicotine restricts blood flow to the gums, making them more vulnerable to infection. Over time, this increases the risk of gingivitis and periodontitis (severe gum disease), and slows down healing.
3. Enamel Damage & Discolouration
Acidic e-liquids and chemicals used in vaping can slowly wear down enamel. While vaping may not stain teeth as quickly as cigarettes, the long-term effects can still include tooth sensitivity, erosion, and yellowing.
4. Disrupted Oral Bacteria
Vaping can upset the natural balance of bacteria in your mouth, creating an environment that promotes plaque, bad breath, and tooth decay.
Vaping vs. Smoking: Is One Really Safer?
Many believe vaping is “less harmful” than smoking – but less harmful does not mean harmless.
When it comes to oral health, both habits pose serious risks, just in different ways:
| Smoking | Vaping |
| Stains teeth rapidly | Weakens enamel, alters bacteria |
| Causes gum disease | Also causes gum damage |
| Burns tissues | Irritates tissues with heat & chemicals |
| Known link to oral cancer | Long-term risks still being studied |
Bottom line: Neither is safe – and both are harmful to your mouth.
What You Should Know in Singapore

Under Singapore law, vaping is illegal – including the possession, purchase, use, or import of vape devices or e-liquids.
However even without the legal risks, the dental consequences alone are enough reason to avoid it.
If you are exposed to vaping, considering it, or trying to quit, here is what we recommend:
- Be informed – vaping can damage your teeth, gums, and smile
- Know your options – Singapore has free quit-smoking support programs like ‘I Quit’ by HealthHub
- See your dentist if you notice signs of gum inflammation, dry mouth, or oral irritation
