The cost of Invisalign treatment (as well as braces) is determined by many different aspects, such as: Extent of Orthodontic Issues. Nearly everyone can benefit from some type of orthodontic treatment. It is very rare for someone’s teeth to come in perfectly straight with no bite misalignment. But every case is different. Some patients will need extensive orthodontic intervention to correct severe problems. Other patients may just need some average straightening of the teeth and bite. The more extensive the treatment you will require, the more expensive Invisalign will be. Length of Treatment. A related factor is the length of your Invisalign treatment. The more extensive corrections you require, the longer it may take to achieve the desired final result. Invisalign consists of a series of plastic aligners that are worn for designated periods of time until switching to the next. The longer your treatment will be, the more aligners will need to be made to shift your teeth into proper alignment, which drives up the cost of treatment. Dentist or Orthodontist. The Invisalign provider you choose will have an affect on the cost of treatment. Each dentist or orthodontist will set their own pricing for treatment and prices may vary between providers. One advantage to Invisalign is that it is available through some dental offices without requiring a referral to an orthodontist. By getting Invisalign through your dentist you can avoid the additional cost of going to a specialist for treatment. Invisalign is a computer based treatment that does not require the same level of expertise that braces require. Where You Live. Your geographical location plays a part in the cost of Invisalign as well. Areas with a higher cost of living, such as cities with higher populations, will tend to have higher prices for orthodontic treatment than smaller towns and rural areas. Dentists and orthodontists will set their pricing based on their own cost of operation and in order to stay competitive with other providers in the area.
