Invisalign FAQs in London

In Canada, Invisalign treatment usually costs between $2,000 and over $10,000. Most patients pay between $3,500 and $8,500. The final cost depends on case complexity, treatment length, your dentist’s experience, and your location. Some dental insurance plans cover part of the cost. Many clinics offer payment plans. Invisalign is a long-term investment in a straighter smile and better oral health.

It depends on how much your teeth need to move. For mild to moderate alignment issues, Invisalign is clear, removable, and generally more comfortable. For complex cases, traditional metal braces are usually more effective because they can handle larger or harder-to-correct movements. Your dentist can help determine which option is best for your teeth.

Invisalign treatment typically takes 12 to 18 months from the first tray to the last. Mild cases may finish in as little as six months, while more complex cases can take 24 months or longer. The total treatment time depends on how severe your alignment issues are and how consistently you wear your trays. Your dentist can give a more precise estimate after examining your teeth.

Aligners should be worn 20 to 22 hours per day for the best results. Remove them only to eat, drink, brush, or floss. Wearing them less than recommended can slow treatment or prevent teeth from moving correctly. Occasional removals for sports or special events are fine, but staying consistent is important. If you are often below the recommended hours, check with your dentist to keep your treatment on track.

Most patients switch trays every one to two weeks, but your dentist will set the schedule for you. Switch when your current tray fits comfortably without pressure. New trays may feel snug at first. Changing trays too early or too late can slow treatment. Always wear aligners 20 to 22 hours per day, removing only to eat, drink, or clean your teeth.

Yes, but remove your aligners before drinking coffee. Afterward, rinse your trays with lukewarm water and clean them to prevent staining and plaque buildup.

Rinse your aligners with lukewarm water each time you remove them. Gently brush with a soft toothbrush and a small amount of clear, mild soap. For deeper cleaning, soak them weekly in Invisalign cleaning crystals, retainer tablets, or a baking soda and water solution. Avoid hot water, toothpaste, mouthwash, scented or colored soaps, and dishwashers, as these can warp or stain your aligners.

Invisalign may cause temporary soreness or pressure, especially when starting a new tray. Most discomfort lasts one to three days and is usually mild. It may feel like tender teeth or pressure as your teeth move. Some irritation on gums or cheeks can occur at first but usually resolves as your mouth adjusts.

Refinements are extra sets of aligners used to make small adjustments after your initial treatment. They are needed if teeth do not move exactly as planned, if attachments loosen, or if your goals change slightly. Refinements help fine-tune tooth positions for a precise final result. Wearing these trays 20 to 22 hours per day and attending check-ups ensures the best outcome

Yes. Many patients with crowns, bridges, or veneers can use Invisalign. Your dentist will check that crowns or restorations are stable and secure. Invisalign applies gentle pressure over teeth and usually moves crowned teeth safely. If a crown is new, your dentist may suggest waiting a few months before starting treatment.

Yes. Teeth can shift after Invisalign because they naturally try to return to their original positions. To maintain a straight smile, you need to wear a retainer. Invisalign offers Vivera retainers, which are strong, durable, and custom-fit. Initially, wear your retainer full-time, then gradually reduce to nighttime use. Maintaining good oral hygiene, avoiding teeth grinding, and attending regular dental checkups will help keep your smile in place.
