How to Stop Bad Breath with Invisalign: Effective Tips and Tricks

Bad breath, also known as halitosis, can be a common concern for individuals wearing Invisalign aligners. While wearing aligners, it's crucial to maintain good oral hygiene to prevent bacteria buildup and eliminate odors effectively. Here’s a comprehensive guide on how to stop bad breath while using Invisalign, ensuring fresh breath and confidence throughout your orthodontic treatment.

Understanding the Causes of Bad Breath with Invisalign

  1. Bacteria Buildup: Aligners create a conducive environment for bacteria to thrive due to reduced saliva flow and snug fit against teeth.

  2. Food Particles: Small food particles can get trapped between teeth and aligners, contributing to bacterial growth and odor.

  3. Dry Mouth: Wearing aligners may cause temporary dry mouth, which reduces saliva production—a natural defense against bacteria and odors.

Effective Strategies to Combat Bad Breath

  1. Maintain a Consistent Cleaning Routine

    • Brush after Meals: Brush your teeth and aligners after every meal or snack to remove food particles and plaque buildup.

    • Floss Regularly: Use dental floss or interdental brushes to clean between teeth and under the aligners where food particles can accumulate.

    • Clean Aligners Thoroughly: Use a soft-bristled toothbrush and clear antibacterial soap to gently brush your aligners at least once a day. Avoid using toothpaste, as it can be abrasive.

  2. Use Mouthwash and Rinse

    • Antibacterial Mouthwash: Rinse with an antibacterial mouthwash to kill bacteria and freshen breath. Choose a mouthwash that is alcohol-free to prevent drying out your mouth.

    • Saltwater Rinse: Rinse your mouth with a saltwater solution to help neutralize acids and kill bacteria that cause bad breath. Mix half a teaspoon of salt in a glass of lukewarm water.

  3. Stay Hydrated

    • Drink Water: Stay hydrated throughout the day to maintain saliva flow, which helps wash away food particles and bacteria that cause bad breath.
  4. Clean Aligners Correctly

    • Use Persulfate-Free Tablets: Soak your aligners daily in persulfate-free tablets dissolved in lukewarm water to effectively remove bacteria and prevent odor buildup.

    • Avoid Hot Water: Never use hot water to clean your aligners, as it can warp the plastic. Stick to lukewarm water to maintain the aligners’ shape and fit.

  5. Monitor Your Diet

    • Limit Sugary and Acidic Foods: Sugary and acidic foods can contribute to bacterial growth and increase the risk of bad breath. Opt for a balanced diet rich in fruits, vegetables, and lean proteins.
  6. Attend Regular Dental Check-Ups

    • Professional Cleaning: Schedule regular dental check-ups every six months or as recommended by your dentist. Professional cleanings help remove plaque and tartar buildup that contribute to bad breath.
  7. Proper Aligner Storage

    • Keep Aligners Clean: Store your aligners in a clean case when not in use to prevent bacteria from accumulating on them.

Tips for Maintaining Fresh Breath Throughout the Day

  • Chew Sugar-Free Gum: Chewing sugar-free gum stimulates saliva production, which helps wash away food particles and bacteria.

  • Use Breath Mints: Sugar-free breath mints can provide temporary relief from bad breath between meals.

  • Avoid Smoking: Smoking and tobacco use can cause persistent bad breath. Quitting smoking can improve overall oral health and breath freshness.


By incorporating these tips into your daily routine, you can effectively combat bad breath while wearing Invisalign aligners. Consistency in oral hygiene practices, using persulfate-free tablets for aligner cleaning, staying hydrated, and monitoring your diet are essential steps towards maintaining fresh breath throughout your orthodontic treatment. Remember, good oral hygiene not only promotes fresh breath but also supports the success of your Invisalign journey, ensuring a confident smile and optimal oral health.
