With the rise in popularity of vaping, it’s important to understand how this habit can impact your oral health – but can dentists tell you vape when you go for your routine checkup? In the following blog, we’re going to take a look at the effects of vaping on oral health, the dental signs that indicate vaping habits, and why regular dental check-ups are important for smokers, vapers and non-smokers alike. Let’s dive in!

Understanding the Effects of Vaping on Oral Health

Vaping, while often touted as a safer alternative to smoking, still has significant implications for your oral health. In particular, the vapour from e-cigarettes contains nicotine, which can reduce saliva flow and lead to dry mouth; this decrease in saliva – which acts as a natural cleanser for the mouth – can increase your risk of tooth decay and gum disease. Additionally, the chemicals and flavourings in vape liquids can also affect oral tissues and enamel.

Dental Signs and Indicators of Vaping

Dentists can identify several signs that may suggest a patient vapes; one of the most common indicators is dry mouth or xerostomia. Patients who vape frequently may also exhibit signs of gum inflammation, such as redness or swelling, without the telltale tobacco stains seen in traditional smokers. Another sign is an increased incidence of cavities, as vaping can lead to a drier oral environment, promoting tooth decay.

Detecting Vaping Habits During Dental Examinations

During a routine dental examination, our London dentist will assess the overall health of your mouth, and this includes looking for signs of changes to your gums and teeth – including those which might have been caused by this costly habit! Changes in oral tissue, the condition of the gums, and the presence of cavities or unusual levels of plaque can all alert your dentist to the possibility of vaping or smoking, and in some cases, dentists might even notice a distinct chemical smell from the vape liquids, especially in the absence of tobacco odours.

Understanding the facts and signs of oral cancer is also crucial in these assessments.

Addressing the Importance of Dental Check-ups

Whether you’re a non-smoker or a smoker, regular dental check-ups are vital for your oral health and wellbeing, but this is especially true for those who vape. These appointments allow your dentist to monitor any changes in your oral health and offer an opportunity to discuss habits like vaping. It’s also important for you as a patient to be honest about your vaping habits – if they exist – as this will allow your dentist to provide tailored advice and treatment plans. Early detection of potential oral health issues can also lead to more effective interventions and prevent more serious problems in the future, so honesty is always the best policy.

If you’ve ever wondered, ‘why are my teeth yellow,’ despite good oral hygiene habits, your dentist can help answer this and provide solutions.

Quit Vaping With The Help Of Your Dentist

Just like doctors, dentists play a key role in educating patients about the oral health risks associated with vaping and smoking, so if you’re looking to quit your expensive habit, feel free to have a discussion with your dentist. Your dentist will usually also be able to offer advice on minimising the risks associated with vaping, such as tips to enhance your oral hygiene routine and using products to mitigate dry mouth. Your dentist may also recommend some preventive strategies – for example, attending more regular teeth cleanings, or trying out certain types of fluoride treatments to mitigate damage and protect your teeth from decay.

The Bottom Line

Ultimately, while dentists aren’t going into your mouth and deliberately looking for signs of vaping, a professional and qualified dentist will likely be able to tell if you’re a smoker or a vapour, most notably by the condition of your teeth. But don’t expect judgement! As dental professionals, we’re committed to providing comprehensive care and guidance to help mitigate the effects of vaping – we’re not here to scold you about your habits.

That said, we would encourage you to be open about any smoking or vaping habits with your dentist – this will help ensure that you receive the most effective and personalised dental care from your dental surgery.


Can vaping cause tooth decay?

Yes, vaping can contribute to tooth decay; the nicotine in vape liquids can reduce saliva flow, leading to a dry mouth condition which is a risk factor for decay. Additionally, the sweeteners and chemicals in vape juices can also increase the risk of cavities.

Is gum disease linked to vaping?

Vaping can indeed be a contributing factor to gum disease; the nicotine found in vaping products can affect gum health by reducing blood flow, leading to swollen, tender, or bleeding gums, which are early signs of gum disease.

Does vaping leave any smell or stains that my dentist can notice?

Vaping typically doesn’t leave the noticeable stains and smells that you might experience with traditional tobacco use. However, dentists might detect a faint chemical scent from the vape liquids during an oral examination.
