What are Clear Aligners?

Clear aligners (invisible aligners) are removable, clear trays that fix misaligned or crooked teeth.

Treatment times vary depending on individual needs and the type of aligner chosen. Aligner treatment typically takes 12 months or less (6 months average). 

Direct-to-Consumer vs. In-Office Clear Aligners

There are two types of aligners available, including direct-to-consumer aligners and in-office aligners:

Direct-to-consumer aligner treatment (at-home teeth straightening) is completed remotely. No orthodontic office visits are required for teeth scans, x-rays, and check-ups. You can also order online impression kits, and the aligners will be sent straight to your door. 

You’ll then send a licensed dentist or orthodontist scans of your teeth throughout the treatment process to ensure everything is going smoothly. Popular remote aligners include Candid, SmileDirectClub, and Byte. 

In-office aligner treatment is completed and monitored in person. You have to visit a dentist or orthodontist to get impressions made. In-office check-ups are also required every few weeks. Popular in-office clear aligners include Invisalign and ClearCorrect.

Is Candid or SmileDirect Better?

Candid and SmileDirectClub both offer direct-to-consumer clear aligners, meaning treatment is monitored in the comfort of your own home.

Both aligner companies also have studios where you can get impressions made in person. You can either visit a Candid Studio, a SmileShop, or order an impression kit online.  

SmileDirectClub can fix minor to moderate bite issues, while Candid can treat more severe issues, including:

  • Crowded Teeth — when some teeth overlap
  • Gapped Teeth (Diastema) — one large gap or multiple gaps between the teeth 
  • Overbites, underbites, and similar issues (depends on the severity)

The main difference between Candid and SmileDirect is that Candid only works with licensed orthodontists. SmileDirect doesn’t work exclusively with orthodontists; they also work with dentists and doctors. This may affect the quality of treatment you receive.

This is why Newmouth recommends Candid over SmileDirectClub.

How Candid Works: Treatment Plan

Five professionals founded Candid. They are partnered with a highly praised orthodontist, Dr. Lynn Hurst, who has over 30 years in practice.

Candid only works with licensed orthodontists who are experts in the teeth straightening industry. This ensures patients get the highest quality care from a professional with years of experience in orthodontics.

Also, Candid only accepts cases that they are confident will benefit from clear aligner treatment. Doing so helps protect customer safety.

If your case falls out of Candid's treatment eligibility requirements, traditional braces are the better option.

How Candid works:

  1. First, you will order a starter kit online or visit a Candid Studio for a free scan (risk free). 
  2. If you are approved for treatment, you will receive the aligners within 2 to 3 weeks after sending back the impressions or visiting a studio.
  3. Candid sends all of your aligners at once. You must wear each set of aligners for at least 22 hours a day.
  4. A qualified orthodontist will track your progress via CandidApp scans that you will take every two weeks. These teledentistry appointments are remote, so you can complete them at any time.
  5. After treatment is done, you will receive a custom retainer that ensures your teeth stay straight for a long time. One set of retainers costs $99.
