Does Vaping CBD Stain Your Teeth?

Posted by David on

Vaping CBD has become increasingly popular as more people turn to cannabidiol (CBD) for its potential benefits. As an alternative to traditional smoking, vaping is often considered a better and more socially acceptable way to consume CBD. However, a common concern among users is whether vaping CBD can stain teeth. In this blog, we will delve into the science behind teeth staining, explore the potential impact of vaping CBD on dental health, and provide practical tips for maintaining a bright, healthy smile.

Understanding Teeth Staining

Teeth staining occurs when the outer layer of the teeth, known as enamel, absorbs pigments from various substances. These pigments can come from foods, beverages, tobacco, and even certain medications. There are two primary types of teeth stains:

Type #1: Extrinsic Stains: These are surface stains that affect the outer layer of the enamel. They are typically caused by the consumption of pigmented substances like coffee, tea, red wine, and tobacco. Extrinsic stains can often be removed or reduced with good oral hygiene and professional cleanings.

Type #2: Intrinsic Stains: These stains occur within the tooth structure itself, often due to factors like aging, trauma, or exposure to certain medications during tooth development. Intrinsic stains are more challenging to remove and may require professional treatments such as whitening or veneers.

The Science of Vaping and Teeth Staining

To understand whether vaping CBD can stain teeth, it's important to examine the components of vape juice and how they interact with dental enamel. Vape oil typically contains the following ingredients:

  • Propylene Glycol (PG)
  • Vegetable Glycerin (VG)
  • Flavorings
  • Nicotine (optional)
  • CBD

Let's further analyze each component's potential impact on teeth staining, so you can get a better understanding.

Propylene Glycol (PG) and Vegetable Glycerin (VG)

PG and VG are the primary base ingredients in vape juice. PG is a colorless, odorless liquid that serves as a carrier for the other ingredients. VG is a thicker, sweet-tasting liquid that produces vapor when heated. Both PG and VG are generally considered safe for consumption and have been used in food and pharmaceutical products for decades.

However, PG can have a dehydrating effect on the mouth, which may reduce saliva production. Saliva plays a crucial role in maintaining oral health by neutralizing acids, washing away food particles, and preventing the buildup of bacteria. Reduced saliva flow can increase the risk of plaque formation and tooth decay, indirectly contributing to staining.

VG, on the other hand, is less likely to cause dryness but can leave a sticky residue on the teeth. This residue can attract bacteria and food particles, leading to plaque buildup and potential staining over time.


Flavorings are added to vape juice to create a variety of tastes, from fruity to dessert-like flavors. These flavorings are often derived from food-grade ingredients, but they can still contribute to teeth staining. Dark-colored and highly pigmented flavors, such as those mimicking coffee, berries, or chocolate, have a higher likelihood of causing extrinsic stains.


While CBD e-liquid may not contain nicotine, it's worth mentioning that nicotine is a known contributor to teeth staining. Nicotine itself is colorless, but when it combines with oxygen, it turns yellow and can stain teeth over time. Additionally, nicotine can reduce blood flow to the gums, increasing the risk of gum disease and further oral health issues.


CBD, the active ingredient in CBD e-juice, is a naturally occurring compound found in cannabis plants. CBD is generally considered safe and non-addictive, with a range of potential health benefits, including pain relief, anxiety reduction, and anti-inflammatory properties. There is no direct evidence to suggest that CBD itself causes teeth staining. However, the overall formulation of CBD vape juice and the frequency of use can influence dental health.

The Impact of Vaping CBD on Dental Health

While CBD itself may not stain teeth, the act of vaping can have several indirect effects on dental health:

1.Dry Mouth (Xerostomia): Vaping, especially with PG-based e-liquids, can lead to dry mouth. Saliva is essential for maintaining oral hygiene, and reduced saliva flow can result in an increased risk of cavities, gum disease, and staining.

2.Plaque Buildup: The sticky residue left by VG can attract bacteria and food particles, contributing to plaque formation. Plaque is a major culprit in tooth discoloration and decay.

3.Flavorings and Additives: The flavorings and additives in vape juice can contribute to extrinsic staining, especially if they are dark or highly pigmented.

4.Gum Health: Poor gum health can lead to receding gums, which expose the more yellowish dentin layer of the teeth. This can make the teeth appear more discolored over time.

Practical Tips for Preventing Teeth Staining While Vaping CBD

To minimize the risk of teeth staining and maintain good oral health while vaping CBD, consider the following tips:

1.Choose High-Quality CBD E-Liquid: Opt for reputable brands that use high-quality ingredients and avoid vape juices with dark or highly pigmented flavorings.

2.Stay Hydrated: Drink plenty of water throughout the day to counteract the dehydrating effects of vaping. Staying hydrated helps maintain saliva production and oral health.

3.Practice Good Oral Hygiene: Brush your teeth at least twice a day with fluoride toothpaste and floss daily. Consider using an electric toothbrush for more effective cleaning.

4.Rinse Your Mouth: After vaping, rinse your mouth with water to help wash away any residue left by the vape juice.

5.Regular Dental Checkups: Visit your dentist regularly for professional cleanings and checkups. Regular dental visits can help identify and address any early signs of dental issues.

6.Use Whitening Products: If you notice any discoloration, consider using over-the-counter whitening toothpaste or treatments. However, consult your dentist before using any whitening products to ensure they are safe for your teeth.

7.Avoid Sugary E-Juices: Sugary vape juices can increase the risk of tooth decay and staining. Opt for e-juices with minimal sweeteners.

8.Monitor Your Oral Health: Pay attention to any changes in your oral health, such as increased dryness, sensitivity, or discoloration. If you notice any issues, consult your dentist promptly.

You Can Still Smile Brightly When Vaping CBD

While vaping CBD itself is unlikely to directly stain your teeth, the overall composition of vape juice and the act of vaping can have indirect effects on dental health. Ingredients like PG and VG, along with flavorings and reduced saliva flow, can contribute to plaque buildup and potential staining. Again, by following good oral hygiene practices, staying hydrated, and choosing high-quality vape juice, you can enjoy the benefits of CBD vaping while minimizing the risk of teeth staining and maintaining a bright, healthy smile. As always, regular dental checkups and professional advice are essential for optimal oral health.
