If you care about your smile and also use a vape, you might be wondering whether vaping stains your teeth. While vaping is often seen as cleaner than smoking, it still raises questions about long-term oral health and the appearance of your teeth.
In this article, we take a closer look at whether vaping can discolour teeth, how it compares to smoking and what you can do to reduce the risk of staining.
Can vaping cause tooth stains?
Yes, it can in some cases, although the staining is generally less severe than with cigarettes. The main culprit is nicotine. When nicotine is exposed to oxygen, it turns yellow. Over time, this can settle on tooth surfaces and contribute to light staining or dullness.
Vape liquids also contain flavourings, sweeteners and colourings, some of which may stick to the teeth or coat the mouth. While not as obvious as the effects of tobacco, frequent vaping can still influence the look and feel of your teeth if oral hygiene is not a priority.
Is it as bad as smoking?
No. Cigarette smoke contains tar and hundreds of chemicals that cling to tooth enamel and cause deep staining. Vaping avoids combustion, which means it does not produce tar. This makes it less likely to cause the brown or yellow stains typically seen in long-term smokers.
That said, vaping still delivers nicotine, and depending on the frequency and style of use, it can still contribute to mild discolouration over time. Sweet or heavily flavoured liquids may also leave a film on your teeth that dulls their natural shine.
What role does flavour play?
Some flavourings, particularly darker ones like cola, coffee or dessert blends, may have more potential to cause staining. These flavours tend to leave more residue in the mouth and on the tongue, which could build up on the teeth if not removed with regular brushing.
If you are using a device like the Lost Mary BM6000, which is known for strong and sweet flavour delivery, it is a good idea to rinse your mouth or drink water after use, especially if you are vaping frequently throughout the day.
Does vaping affect enamel?
Vaping itself does not appear to damage enamel directly in the way that sugary drinks or acidic foods do. However, if vaping causes dry mouth, the lack of saliva can reduce your mouth’s natural ability to wash away bacteria and acids, which may increase the risk of plaque build-up or surface staining.
Saliva plays a key role in keeping your mouth clean. If vaping reduces this, even slightly, you may need to be more proactive about your oral care routine.
How to prevent vape-related staining
If you are concerned about the appearance of your teeth while vaping, here are some simple tips:
-
Brush your teeth twice a day with fluoride toothpaste
-
Use an electric toothbrush if possible
-
Rinse your mouth with water after vaping
-
Visit your dentist for regular cleaning
-
Drink water regularly to support saliva production
-
Limit sweet or dark flavours that may leave more residue
You can also speak to your dentist about whitening toothpaste or professional cleaning if staining becomes noticeable.
Are nicotine-free vapes better for your teeth?
Nicotine-free vape liquids are less likely to cause staining because they avoid the yellowing effect linked to oxidised nicotine. However, they still contain flavourings and other ingredients that might affect your mouth if used frequently.
If you are looking to reduce the risk of discolouration or maintain a whiter smile, switching to nicotine-free options could help, but you still need to look after your teeth daily.

Final thoughts
Vaping is less likely to stain your teeth than smoking, but it is not completely free from cosmetic effects. Nicotine, flavourings and reduced saliva can all contribute to dullness or light staining over time, especially with frequent use.
Good oral hygiene, regular dental care and mindful flavour choices can help reduce the impact. If you are switching flavours or cutting back on strength, the Lost Mary BM6000 collection offers a wide variety of options in a convenient, refillable format.
