Invisalign Handout – Instruction on Wear and Care

Q: How much does Invisalign cost? A: The cost for Invisalign treatment varies from patient to patient, and depends on the severity of the case. If you are a candidate for Invisalign, we will take records (x-rays, photos, etc) at your consultation appointment in order to properly diagnose your treatment. Specifics of your cost be outlined at your follow-up appointment, after the records have been evaluated. If you wish, ranges may be offered at the initial consultation appointment, upon request.

Q: Is Invisalign more expensive than braces? A: Yes, Moshiri Orthodontics has to pay a third party lab fee to Align Technology to prescribe the appliance, along with their specific retainers (Vivera). Thus, there is an increased fee to use Invisalign. Generally speaking, patients have the option of choosing Invisalign OR braces for their treatment.

Q: What is the difference between Invisalign and braces? A: Generally speaking, Invisalign is more a more hygienic appliance and exerts less pressure than braces. For specific scenarios, Invisalign is a more precise appliance due to the vast amount of technology incorporated versus braces, thus allowing for shorter treatment times for certain patients.

Q: How often must I wear my aligners? A: Patients must wear aligners for AT LEAST 22 hours daily. Aligners may be removed for eating, drinking and regular/frequent oral hygiene.

***The success of your treatment is directly correlated to compliance with our instructions regarding the amount of Invisalign aligner wear***

Q: Are there any restrictions to what I can eat while in treatment? A: Yes, like braces, you must be careful of breaking the attachments off of your teeth that are used to retain the aligners. Broken attachments may cause teeth not to move in the desired direction that the aligners are pushing towards.

Prior to placing the aligners back on, it is important to brush your teeth AND the aligners after you eat.

Q: Will wearing the aligners affect my speech? A: Like any orthodontic treatment, there is a short adjustment period. The aligners are very thin, but you will notice them at first. The more you speak with the aligners on, the quicker you will adjust.

Q: What are Invisalign attachments? A:  The Invisalign aligners are only as effective as the amount of surface area the aligners have to exert force upon. Thus, for more difficult movements, attachments (clear buttons made of dental composite) are cemented onto teeth for the duration of treatment to facilitate orthodontic movements occurring predictably.

Q: Is there any discomfort with Invisalign® treatment? A: There will be some pressure and minor discomfort for a day or two after each initial insertion. This is a sign that your teeth are moving sequentially into their final position. Advil taken per our instructions will help to alleviate this discomfort.

Q: Can I chew gum? A: It is recommended that you remove your aligners prior to chewing gum as the gum will stick to the aligners.

Q: Can I smoke with the aligners in? A: We discourage smoking with aligners as the cigarette smoke will tend to discolor them.

Q: How do I keep my aligners clean? A: Brushing them with toothpaste will keep them fresh and clean. Additionally, aligners may be soaked in luke warm/tepid water and denture cleaning tablets two to three times a week for about 15 minutes.

Q: How often do I see an orthodontist while wearing Invisalign®? A: Regular office visits are every six to 10 weeks on average. This will ensure that your Invisalign treatment is progressing as planned. This may vary from patient to patient depending on Drs. Moshiri’s recommendations.

Q: What happens after my treatment is complete? Do I need retainers? A: All of our orthodontic patients are instructed to wear their retainers for 6 months full-time, and then at night indefinitely. Teeth, like every other parts of our body, have a tendency to move with age; thus, lifetime retention of your results are necessary.

Q: How long does Invisalign treatment take? A: Treatment time varies depending on the severity of the misaligned teeth. Treatment time may be shorter than traditional braces, but generally last between 12-18 months

Q: Does Invisalign work for teenagers? A: Yes, if their teeth, including second molars, have grown in completely, teenagers can make excellent candidates of orthodontic treatment with Invisalign.
