How Long Does Straight Direct Teeth Straighten Teeth?

Straight Teeth Direct usually takes 5 to 9 months to get your teeth straightened out.2 However, you should start seeing results within 90 days of beginning treatment.3

  • All your clear aligners
  • Remote progress tracking
  • Straight Teeth Direct app
  • The first set of retainers

Does NHS Cover Straight Teeth Direct Aligners?

Straight Teeth Direct treatments are cosmetic and aren’t covered by the National Health Service (NHS). The NHS only covers orthodontic treatments that are necessary for maintaining oral health.

Does Insurance Cover Straight Teeth Direct?

It depends. If you’re privately insured, your insurance company may cover the cost. It’s best to ask them about your aligner treatment coverage

How Does Straight Teeth Direct Work?

Straight Teeth Direct has a simple and easy-to-follow process. Here are the steps so you’ll know what to expect from the treatment:

Step 1: Choose how you want to begin

If you want a fully remote aligner treatment: You can start with an online quiz. During this step, you’ll be asked to do the following:

  • Answer questions (e.g., what you want to improve about your teeth)
  • Send recent photos of your teeth from different angles

After taking the free e-consultation, a local dentist will review your case and determine if you’re a good candidate. They’ll get back to you within 24 hours, and you can ask them questions.

People who qualify for the treatment can purchase the dental impression kit (SmileBox®). It includes instructions so you can take your own teeth impressions and send them back.

If you prefer to see an expert: You have to sign up for an online account before you can schedule an in-person appointment at their Central London clinic. During your visit, they will:

  • Visually assess your teeth to determine your candidacy
  • Interview you and ask questions (e.g., what your smile goals are)
  • Get your teeth scanned digitally using advanced equipment
  • Send your dental scans to Straight Teeth Direct

Step 2: Approve your treatment plan

A UK-registered orthodontist will create your personalised treatment plan using dental impressions and teeth scans. The plan will include important information such as:

  • Your diagnosis
  • Estimated treatment time
  • Predicted teeth movements

You can review the initial plan, request changes, ask more questions, and decide against the treatment. If you approve the plan, you’ll be prompted to proceed with the payment.

Step 3: Finish your aligner treatment at home

The company will send your clear aligners in sets instead of all at once. Depending on your teeth’s movement, you’ll receive the next set as soon as possible.

Most people receive their clear aligners every two months. Expect at least four deliveries and five aligners with each delivery. You can start wearing them as soon as they arrive. 

Each aligner tray must be worn for 22 hours daily and switched every 2 weeks. You must also check in with the dental team every month so they can track your progress. 

The Straight Teeth Direct app will remind you when to change aligners. It’s also used to upload photos of your teeth. The dental team will review your progress and may decide to:

  • Adjust your treatment schedule based on the movement of your teeth
  • Send your next set of clear aligners so you can continue the treatment

At the end of the treatment, your assigned orthodontist will review the final results. They will help you decide if you need more aligners or if you can wear retainers.

Step 4: Maintain your smile

Now that you’ve achieved your ideal smile, the next step is to wear retainers for life. Retainers will keep your teeth straight and prevent them from shifting back into place. You’ll also have the option to whiten your teeth.

Straight Teeth Direct Customer Reviews

I was very insecure with my teeth… Straight Teeth Direct was something that my sister used for her smile and recommended. I cannot describe how happy I am with them. They [were] so easy and straightforward with their process.

Straight Teeth Direct Review on Trustpilot

The staff are so helpful and message you back if you are struggling. My process was for a year, and my teeth are so nicely aligned. I would recommend them 100% to anyone who is insecure with their smile

Straight Teeth Direct Review on Trustpilot

This is a great team of professionals who know their job, don’t waste people’s time, and create a perfect smile. I am also still in contact as I have stayed on the maintainer plan with the retainers.

Straight Teeth Direct Review on Trustpilot

Happy with the results but a couple of issues. Their customer service is very good. My two issues are that for a large part of my treatment, my top retainer did not fit properly. Although I kept on sending in photos, it took about 6 to 8 months for them to acknowledge that something was wrong.

Straight Teeth Direct Review on Trustpilot

But as soon as they did, they asked me to do some more moulds, and they sent out some new retainers quite quickly. Even my final retainer is not the best quality as it poorly fits around my back molar.

Straight Teeth Direct Review on Trustpilot

The other issue is with the payment, I chose to go with the payment plan of 3 lots of £500. They took all my payments months earlier than expected, and when the time came that they should [have] taken the payments they kept trying to take money out [of] my account!

Straight Teeth Direct Review on Trustpilot

The problem was sorted very promptly, but the whole situation [defeated] the point of a payment plan! I do have the results I wanted now, but the process wasn’t 100% as smooth as I expected.
