Clear Aligners IFU


Clear Aligners

Description of Device

The Dandy Clear Aligners System contains a sequence of doctor-approved, custom processed, clear plastic removable aligners that gradually move the patient’s permanent teeth in small increments from their original misalignment to a more optimal, aligned and treated state. This device is a personalized medical device intended only for use by the individual specified on the packaging.

Indications for Use - Aligners

The Dandy Clear Aligners System is indicated for use in the alignment of permanent teeth through orthodontic treatment of misalignment and malocclusion.

Indications for Use - Retainers

Dandy Retainers are indicated to prevent a patient’s teeth from shifting position following orthodontic treatment.


Not to be used if the patient is allergic to plastics. It is not advised for patients with active periodontal disease.


  • In rare occurrences, patients may be allergic to the thermoplastic polyurethane material of the aligners. Advise patients that if swelling or extreme redness occurs, discontinue use immediately and consult you or other health care professionals.
  • In rare occurrences, patients with HAE (Hereditary Angioedema) may experience local swelling, which can be triggered by dental procedures or appliances. If extreme swelling occurs, advise patients to discontinue use immediately and consult you or other health care professionals.
  • Because the aligners are worn in the mouth, accidental swallowing or aspiration of the appliance may occur and may be harmful if not immediately addressed.

Precautions / Potential Risks of Aligner System. Advise Patients of the Following:

  • Keep aligners away from hot water and harsh chemical solutions.
  • Keep aligners out of reach for both young children and pets. When not in use, store aligners in the provided case.
  • Aligners worn out of sequence can delay treatment and result in complications, including patient discomfort. Always follow the prescribed order and wear of aligners.
  • Uncharacteristically shaped teeth and missing teeth can potentially extend treatment time and may affect the potential to achieve desired results.
  • Existing fixed dental restorations (crowns, bridges) may become dislodged during aligner wear and may require re-cementing or replacement. Any new fixed dental restorations placed during aligner treatment may result in the need for a revised treatment plan and new aligner(s).
  • Aligner appliances are not effective in the movement of dental implants.
  • Certain medications and medical conditions can affect orthodontic treatment. Patients should consult their prescribing physician before beginning treatment.
  • Sensitivity and tenderness to teeth may occur during treatment, especially when moving from one aligner step to the next.
  • Aligner wear may temporarily affect speech, resulting in a slight lisp. Patients typically adapt quickly to the aligners within a week or two.
  • Patients may experience an increase in salivation or dryness of the mouth. Some medications can increase this. 
  • Extended treatment time may occur due to poor compliance of doctor’s instructions, wearing aligners less than the prescribed hours, missing appointments, poor oral hygiene, excessive bone growth, or broken appliances. Increased cost and/or the ability to achieve the desired results may occur.
  • Irritation of the soft tissue in the mouth (gums, cheeks, tongue and lips) may occur. Patients should consult with you if this persists.
  • Some treatment plans may require “attachments” (small bumps of tooth-colored composite material) to be temporarily bonded to one or more teeth to assist with tooth movement. These are critical to proper movement and should be replaced if they fall off.
  • All “attachments” should be removed upon treatment completion.
  • Tooth decay, permanent stains/decalcification and periodontal disease (inflammation of the gums) may occur if proper oral hygiene is not followed and preventive maintenance is not followed.

Precautions / Potential Risks if the Aligner System is Continued:

  • In the presence of severe crowding, interproximal reduction (IPR – reducing the thickness of enamel on the tooth) may be required to produce enough space for proper tooth movement and alignment. Risk associated with IPR as part of treatment should be taken into account.
  • The health of gums and bone, both of which support the patient’s teeth, can be affected by wearing aligners.
  • Throughout the course of treatment, the bite will change and may result in temporary patient discomfort in the jaw joint. Although rare, patients may experience joint pain, headaches or ear problems. Patients should inform their doctor if any of these symptoms occur.
  • At the end of the treatment, it may be necessary to make adjustments to the bite.
  • All teeth should be at least partially covered by aligners to avoid supra-eruption of the teeth.
  • Aligner wear can aggravate teeth, including previously traumatized or significantly restored teeth. In rare occurrences, additional dental treatment might be required such as, but not limited to, endodontic treatment, additional restorative treatment, or the tooth may be lost.
  • Root resorption (shortening of the root of the tooth) can occur during any orthodontic treatment, including aligner appliances, and could threaten the longevity of the teeth.
  • Supplemental treatment in addition to aligner appliances may be required for severe open bite, over jet, excessive crowding or skeletal jaw disproportions. If oral surgery is required, all risks of surgery and anesthesia must be taken into consideration before treatment.
  • Other fixed and/or removable orthodontic appliances may be required for more complicated treatment plans where aligners alone will not be adequate to achieve the desired outcome.
  • Once treatment has been completed, teeth may shift positions if the proper and consistent wearing of retainers is not followed.
  • Upon completion of aligner treatment, some cases may require enhancement with additional aligners, traditional orthodontic treatment and/or cosmetic restorations such as veneers or crowns to achieve ideal results. Successful treatment outcome cannot be guaranteed.

Directions for Use

  • Rinse the new aligners with cold water prior to wear.
  • If any extractions have been performed prior to aligner treatment beginning, space should be maintained while healing occurs. Attachments should only be applied after healing is completed in the extraction site.
  • Review the Use and Care Instructions with the patient. 
  • Complete attachment placement and perform any required IPR (interproximal reduction) as required by the treatment plan.
  • Seat Step #1 aligner on the patient’s teeth and check for tissue impingement/blanching. If necessary, trim aligner and polish the trimmed area.
  • Each set of aligners are designed to be exchanged with the next step aligner in sequence, after approximately two weeks of wearing the aligner(s) 20-22 hours per day.
  • Provide the patient with the first 2 sets of aligners and Dandy’s Clear Aligner Accessory Kit, which includes an aligner case, aligner OrthoChewsTM, Clear Aligner cleaning spray, a zippered pouch, a patient education pamphlet, and a tote.
  • At follow-up appointments, check teeth for proper interproximal contacts and perform IPR as required by the treatment plan. Check for appropriate aligner stage, fit and treatment progress.
  • Provided treatment is on track, provide the next set(s) of aligners. Treatment and progress should be monitored on a monthly appointment schedule unless otherwise required in the treatment plan.
  • New scans and aligners may be required if treatment requires modifications or refinements.
  • At the completion of aligner treatment, retainer wear is highly advised to maintain corrected alignment. Retainer wear should follow the same instructions for aligner wear as described above, unless advised otherwise by a dental professional.

Daily Care and Maintenance of Clear Aligners by Patients

  • Clean Aligners prior to insertion. Use Dandy’s Aligner Cleaner or a soft-bristled toothbrush and water. Do not expose aligners to hot water.
  • Take care to rinse each aligner thoroughly with cool water after cleaning and before wearing.
  • It is recommended to clean aligners once a week or as needed using the Dandy Clear Aligner cleaning spray.
  • Do not use denture cleaner, whitening toothpaste or soak aligners in mouthwash. These products can deteriorate the surface of the aligner and cause them to become dull or cloudy.
