Like any medical treatment, clear aligners come with their own set of frustrations. Being honest about them upfront leads to better decisions and fewer surprises mid-treatment. Here are the most common complaints we hear from patients, and our perspective on each.

  • Initial lisp: Present in some patients for only a few days, and resolves quickly as the tongue adapts. Most patients find it barely noticeable.
  • Discomfort with new trays: Expected for 1–3 days after switching. Manageable with over-the-counter pain relief.
  • Inconvenience of removing trays before every meal: The most universal complaint. It becomes habitual quickly, but the first few weeks require conscious effort.
  • Trays staining yellow: Usually caused by drinking coffee, tea, or coloured drinks without removing trays first. Avoidable with the right habits.
  • Tray fit issues: Occasional — if a new tray does not seat properly, contact your clinic. Do not force it.
  • Forgetting to replace trays after meals: Especially common in the first month. A phone reminder solves this.

Most of these frustrations are temporary or habit-based. The ones worth taking seriously — persistent pain, a significantly poor-fitting tray, or visible unexpected tooth movement — should always be flagged to your orthodontist promptly.
