Vaping can offer a smooth and enjoyable experience, but nothing disrupts that more than getting vape juice in your mouth. Whether it’s caused by a flooded coil, improper airflow, or vaping techniques, there are several common reasons for this issue. Understanding these causes and applying the right solutions can help you prevent vape juice from ever reaching your mouth again.

Why Does Vape Juice End Up in Your Mouth?

The problem of e-liquid entering your mouth, commonly referred to as “spitback,” can arise for several reasons:

  1. Overfilling the Tank: One of the most common mistakes is filling the tank beyond its capacity. When you overfill the tank, there’s no room for the liquid to expand as it heats up, which leads to leakage through the mouthpiece.
  2. Flooded Coil: A coil that is oversaturated with e-liquid can cause spitback. This often happens when the coil is not primed correctly or is due for replacement.
  3. Airflow and Inhalation Technique: Improper airflow settings and a poor inhalation technique can also cause e-liquid to be drawn into your mouth instead of vaporizing properly.
  4. Incompatible E-liquids: High PG (propylene glycol) liquids are thinner and can cause leakage in certain devices, especially those optimized for thicker e-liquids like high VG (vegetable glycerin) blends.
  5. Equipment Issues: Damage to your device, such as a cracked tank or a loose seal, can allow e-liquid to leak into unwanted areas, leading it directly to your mouth.

How to Prevent Vape Juice from Getting in Your Mouth

To eliminate this issue, you can apply the following effective tips:

  1. Check and Replace Your Coil
    A flooded coil is one of the most common causes of spitback. Before each vape session, check to ensure your coil is not oversaturated. If you suspect the coil is the issue, remove the tank, blow through the drip tip to clear any excess liquid, and reassemble it. Regularly replacing the coil when necessary is another key step to preventing this issue​.
  2. Avoid Overfilling Your Tank
    Always follow the fill line indicated by the manufacturer. Overfilling can result in liquid overflow, which may lead to spitback. After filling, give the device a moment to stabilize before vaping.
  3. Adjust Your Airflow Settings
    Many vape devices allow for airflow customization. If you notice vape juice getting into your mouth, try adjusting the airflow to find the balance that works best for your setup. More airflow often means less chance of oversaturation, leading to a cleaner vape​.
  4. Prime Your Coils Properly
    Whenever you install a new coil, make sure to prime it by saturating it with e-liquid and allowing it to sit for a few minutes. This helps ensure the wick is adequately soaked without oversaturating, preventing spitback​.
  5. Use Proper Inhalation Techniques
    Taking strong, sharp hits can pull excess e-liquid into your mouth. Instead, focus on taking slow, steady inhales to reduce the chances of liquid reaching your mouthpiece. Adjust your airflow if needed to complement your inhalation style.
  6. Try a Drip Tip with a Splash Guard
    Consider upgrading to a drip tip with a built-in splash guard. This can help prevent liquid from spraying into your mouth, especially if spitback occurs due to coil issues or high wattage.
  7. Experiment with E-Liquids
    If you often experience spitback, it might be related to the type of e-liquid you’re using. E-liquids with higher VG content are generally thicker and less likely to cause spitback. Experiment with different ratios to find the one that suits your device.
  8. Keep Your Device Clean
    A dirty vape device can lead to a build-up of residue that interferes with proper function. Regularly clean your tank, mouthpiece, and other components to ensure they are free of debris. This not only prevents spitback but also enhances the overall performance of your device​.
  9. Check for Hardware Damage
    Inspect your vape for any cracks or damaged seals. A broken tank can lead to leaks, causing e-liquid to enter the mouthpiece. If you notice any damage, it’s time to replace the part or invest in a new device​.
  10. Adjust Wattage Settings
    Running your device at too high a wattage can vaporize the liquid too quickly, resulting in spitback. Try lowering the wattage to a level that still provides enough vapor without overwhelming the coil.

Conclusion: Enjoy a Cleaner, More Satisfying Vaping Experience

Getting vape juice in your mouth is a frustrating problem, but it’s easily avoidable with the right practices. By ensuring your coil is well-maintained, adjusting your vaping technique, and keeping your device clean, you can prevent spitback and enjoy a smooth, hassle-free vaping session. If issues persist, seeking professional advice or upgrading your device might be the next step toward solving the problem for good.

By following these steps, you can avoid the annoyance of vape juice in your mouth and enjoy a more pleasant vaping experience.
