Invisalign & Clear Aligners in Fountain Valley, CA
Straightening your teeth with clear aligners, often referred to as Invisalign, is about more than improving your smile. It supports your long-term dental health, your bite, and your overall comfort.
What is Invisalign?
Most people searching for “Invisalign” are actually searching for clear aligners, the removable, nearly invisible trays that gradually move teeth into alignment. Invisalign is one brand that offers this type of treatment. But it is not the only option, and it may not always be the best one for your case.
How does Invisalign & other clear aligner treatment work?
Clear aligners are custom-made trays worn over your teeth for about 20 to 22 hours per day. Each set of trays applies gentle pressure to gradually shift your teeth toward their ideal position. You move to a new set of trays every one to two weeks, depending on your treatment plan.
There are no brackets or wires. You take the trays out to eat, brush, and floss. Most people around you will not notice you are wearing them at all.
Clear aligners can be used to treat:
- Crowded or overlapping teeth
- Gaps between teeth
- Overbites and underbites
- Crossbites and open bites
- General misalignment
The right system for your case depends on your teeth, your bite, and your treatment goals.
