Short answer
Invisalign® is a system of clear, custom-made plastic trays called aligners. You wear a new set every so often, and each set moves your teeth a little closer to the planned position. A dentist checks your teeth and bite first to see whether clear aligners suit you.
How clear aligners work
Your dentist plans the movement of your teeth in stages. A series of clear aligners is then made to match each stage. Each set applies gentle pressure to move your teeth a small amount. Over time, your teeth shift to the planned position.
The aligners are removable, so you take them out to eat, drink anything other than water, and clean your teeth.
Who may be suited to clear aligners?
Clear aligners are used for a range of alignment concerns, such as crowded teeth or gaps. They are not right for everyone. Some bite problems or complex tooth movements may need other treatment. Gum disease and cavities should also be treated first.
Only an exam can show whether aligners suit you. Teenagers and adults can both be assessed.
What treatment involves
- Consultation. The dentist examines your teeth, gums and bite and discusses your goals.
- Records. Images, scans or impressions of your teeth are taken.
- Treatment plan. You see how your teeth are expected to move and how long treatment may take.
- Receiving aligners. You are given your first sets and shown how to wear and care for them.
- Check-ups. You return from time to time so your dentist can check progress and give you new aligners.
- Finishing. When your teeth reach the planned position, you move on to retainers.
The length of treatment depends on your teeth and how closely you follow the plan. Your dentist will give an estimate for your case.
Wearing and caring for aligners
- Wear aligners as directed. Most plans ask for around 22 hours a day.
- Take them out to eat and drink anything but water.
- Brush and floss before you put them back in.
- Clean them as your dentist advises and keep them in their case when they are out. Never wrap them in a napkin, where they are easily thrown out.
- Keep your next set until you are told to switch.
After treatment: retainers
Teeth can move back after treatment. A retainer helps hold them in their new position. Your dentist will tell you how and when to wear it.
Clear aligners and braces
- Clear aligners are removable and discreet. They need you to wear them for most of the day.
- Traditional braces are fixed to the teeth and work continuously. They may suit some bite problems better.
A dentist can explain which approach is likely to work for your teeth.
