Mountainside Dental in Lake Forest offers Invisalign clear aligner treatment for adults and teens looking to straighten their teeth without metal brackets. Our El Toro Road office has provided orthodontic care to patients across Lake Forest, Mission Viejo, Irvine, and Laguna Hills since 2018.

How Invisalign Works
Invisalign uses a series of custom-made, clear plastic trays to shift teeth into proper alignment over time. Each set of aligners applies controlled pressure to specific teeth, moving them in small increments according to a digital treatment plan created by your dentist.
Invisalign aligners are made from SmartTrack material, a patented thermoplastic designed for orthodontic movement. SmartTrack is more elastic than earlier aligner materials, which allows it to apply consistent force throughout each two-week wear cycle. Invisalign aligners are FDA-cleared and BPA-free.
Your dentist uses 3D imaging software to map the entire treatment sequence before you receive your first tray. This digital plan shows exactly how each tooth will move and estimates your total treatment timeline. You can preview your projected results before starting treatment.

Your Invisalign Treatment in 5 Steps
Initial Consultation
Your dentist evaluates your teeth, bite, and oral health to determine if Invisalign is the right option. We discuss your goals and answer questions about the process.
3D Digital Scan
We take a precise 3D scan of your teeth using an iTero digital scanner. No messy impressions. The scan generates your custom treatment plan and projected outcome.
Custom Aligner Fabrication
Invisalign manufactures your full set of aligners based on the 3D treatment map. You receive several sets at once and switch to a new tray every one to two weeks.
Progress Check-Ins
You visit our Lake Forest office every 6 to 8 weeks so your dentist can monitor tooth movement and provide your next batch of aligners.
Retainer Phase
After your final aligner, you receive a custom retainer to maintain your new alignment. Retainer wear prevents teeth from shifting back over time.

Who Qualifies for Invisalign
Invisalign treats a wide range of orthodontic issues in teens and adults. Most patients with mild to moderate alignment problems are good candidates. Your dentist at Mountainside Dental Lake Forest will evaluate your specific case during a consultation.
Invisalign can correct crowding, gaps between teeth, overbite, underbite, crossbite, and open bite. The system works well for patients who had braces as teenagers but experienced relapse. Invisalign Teen includes compliance indicators and replacement aligners for younger patients.
Invisalign is not recommended for severe skeletal jaw discrepancies, certain complex bite issues, or patients who cannot commit to wearing aligners 20 to 22 hours per day. In those cases, your dentist may recommend traditional orthodontic treatment or a referral to an orthodontic specialist.

Invisalign vs Traditional Braces
Choosing between Invisalign and traditional braces depends on your orthodontic needs, lifestyle, and budget. Both options achieve effective results for many cases. The American Dental Association recognizes clear aligners and fixed braces as accepted orthodontic treatments.
Appearance
Invisalign trays are nearly invisible. Traditional braces use visible metal or ceramic brackets and wires attached to teeth.
Comfort
Invisalign has smooth plastic edges with no brackets to irritate cheeks. Braces can cause sores during the adjustment period.
Removability
Invisalign trays are removable for eating, brushing, and flossing. Braces are fixed in place for the full treatment duration.
Treatment Time
Invisalign averages 12 to 18 months for most cases. Traditional braces average 18 to 24 months depending on complexity.
Cost
Invisalign costs $3,000 to $8,000. Traditional braces cost $3,000 to $7,000. Insurance may cover a portion of either option.
Office Visits
Invisalign requires check-ins every 6 to 8 weeks. Braces require adjustments every 4 to 6 weeks with longer appointments.

Cost and Financing for Invisalign in Lake Forest
Invisalign treatment at Mountainside Dental Lake Forest costs between $3,000 and $8,000. The exact price depends on the complexity of your case, the number of aligners needed, and your treatment duration. Your dentist provides a specific cost estimate after the initial consultation and 3D scan.
Many dental insurance plans cover Invisalign the same way they cover traditional braces. If your plan includes an orthodontic benefit, it may pay $1,000 to $2,000 toward treatment. Our front office team verifies your insurance benefits before you begin and explains your out-of-pocket costs in advance.
Flexible Payment Options
Mountainside Dental offers financing through CareCredit, which provides low-interest and interest-free payment plans for qualified patients. We also accept HSA and FSA funds for Invisalign treatment. Ask our team about monthly payment options during your consultation.
