What is Invisalign?

Invisalign is a brand of clear aligners: removable plastic trays that gradually move teeth. You switch to a new set every 1–2 weeks and wear them about 20–22 hours a day. It treats many crowding, spacing and mild-to-moderate bite problems.

Invisalign: specialist or general dentist?

Both orthodontists and general dentists can provide Invisalign. Orthodontists have 2–3 extra years of training in tooth movement. They are often recommended for complex bites, jaw issues, or cases where aligners alone may not be enough.

None of Nashua's 46 clinics offering Invisalign list an orthodontist on staff in our data yet. See orthodontists in Nashua

How much does Invisalign cost in Nashua?

Typical ranges in USD for Nashua, NH. Your price depends on the tooth, the case and the clinic.
