How painful is the first week of Invisalign?
The first week of Invisalign involves mild to moderate discomfort rather than pain. Most patients experience tooth sensitivity and pressure for 2-4 days, which is manageable with over-the-counter pain relief. Discomfort significantly decreases by day 4-5, and most patients report minimal issues by week's end.
Will I have a lisp with Invisalign in New Zealand?
Many people notice a slight lisp during the first few days. This resolves quickly as your tongue adjusts to the aligners. Practicing reading aloud and speaking slowly helps accelerate adaptation. Most patients speak completely normally by day 3-4.
How long do I wear Invisalign aligners per day?
Invisalign aligners must be worn 20-22 hours per day for optimal results. This allows only 2-4 hours total for eating and cleaning. Consistent wear is critical - reduced wear time extends treatment duration and compromises results. Track your wear time carefully during the first week to build good habits.
What can I eat during the first week of Invisalign?
You can eat anything with Invisalign, but must remove aligners first. During the first week when teeth are sensitive, soft foods like yogurt, smoothies, pasta, and soups are more comfortable. Avoid very hard, crunchy, or chewy foods that require excessive force. Always brush before reinserting aligners.
How much does Invisalign cost in New Zealand?
NZ practices publish $6,500 – $13,000 for full Invisalign or clear-aligner treatment and $4,500 – $7,900 for shorter (Lite) courses. Costs vary with complexity, treatment length and what the fee includes. Some clinics offer payment plans or third-party finance: ask for the full cost, fees and interest in writing. Compare written quotes from more than one provider.
