What is the Biggest Complaint with Invisalign?

The biggest complaint with Invisalign often relates to maintenance and cleanliness. Keeping aligners clean is crucial to avoid odor and buildup. Using a purple persulfate-free retainer cleaner helps ensure effective cleaning without harsh chemicals, addressing this common concern and promoting better oral hygiene during treatment.

1. Discomfort and Soreness

  • Initial Discomfort: Some patients experience discomfort or soreness when they first start wearing Invisalign aligners. This discomfort is typically due to the pressure exerted on the teeth to move them into the desired position.

  • Tight-Fitting Aligners: Aligners are designed to fit snugly over the teeth to facilitate movement. While this ensures effectiveness, it can cause initial discomfort until the mouth adjusts to wearing them.

2. Speech Impediments

  • Lisping or Speech Changes: Aligners can temporarily affect speech patterns, causing a slight lisp or difficulty pronouncing certain words. This adjustment period varies among individuals but generally improves as the tongue and mouth adapt to the aligners.

  • Speaking with Confidence: Practicing speaking aloud and consistently wearing aligners helps in overcoming speech changes, ensuring clear communication without impediments.

3. Compliance and Maintenance

  • Wear Time Requirements: Invisalign aligners must be worn for 20-22 hours a day to achieve optimal results. Some patients find it challenging to comply with this requirement, especially during meals or social occasions.

  • Responsibility for Maintenance: Aligners require regular cleaning to prevent plaque buildup, odors, and discoloration. Failure to maintain proper hygiene can lead to oral health issues and dissatisfaction with the appearance of aligners.

4. Aligner Fit and Comfort

  • Fit Issues: Occasionally, aligners may not fit properly, causing discomfort or irritation to the gums and cheeks. This can occur if there are discrepancies in the manufacturing process or if aligners are not properly seated.

  • Refinement Aligners: In some cases, additional sets of aligners (refinement aligners) may be needed to achieve the desired results. This process can prolong treatment time and may lead to frustration if expectations are not met promptly.

5. Lifestyle Adjustments

  • Dietary Adjustments: Aligners must be removed before eating or drinking anything except water to prevent damage and staining. This requires careful planning and adjustments to dietary habits, which can be inconvenient for some individuals.

  • Social Situations: Removing aligners for social occasions or meals may disrupt daily routines and social interactions. Some users may feel self-conscious or inconvenienced by the need to remove and replace aligners frequently.

6. Cost Considerations

  • Financial Investment: Invisalign treatment can be more expensive than traditional braces, depending on the complexity of the case and the number of aligners required. Cost considerations may influence a patient's decision to pursue treatment with Invisalign.

  • Insurance Coverage: Not all dental insurance plans cover Invisalign treatment. Patients should inquire about coverage and explore financing options to manage the financial aspect of treatment effectively.


While Invisalign offers numerous benefits, including aesthetic appeal, comfort, and convenience, it is essential to be aware of potential drawbacks. Addressing common complaints such as discomfort, speech changes, compliance issues, aligner fit, lifestyle adjustments, and cost considerations can help patients make informed decisions about their orthodontic treatment. Consulting with an experienced orthodontist can provide valuable insights and personalized recommendations to ensure a successful and satisfying Invisalign experience.
