Choosing Between Invisalign and SmileFast: A Comparative Guide

Invisalign vs. SmileFast: A Comprehensive Guide

Welcome to Crestmead Dental, your trusted partner in achieving a radiant smile in the Crestmead, Marsden, and Berrinba areas. Today, we delve into the modern orthodontic landscape, focusing on two popular options: Invisalign and SmileFast. Let’s explore these innovative solutions to straighten your teeth, transforming crooked teeth into a source of pride and confidence.

Understanding Invisalign and SmileFast: Key Features

Invisalign employs a series of clear, removable plastic trays, custom-made to fit snugly over your teeth. These aligners apply gentle pressure, gradually shifting your teeth into their desired positions.

  • Clear Aligners: Invisalign uses transparent, plastic trays that are almost invisible, offering an aesthetic advantage, especially for adults.
  • Removable Trays: These aligners can be taken out for meals and oral hygiene, facilitating easier brushing and flossing.
  • Customization: Each Invisalign tray is custom-made using 3D imaging technology, ensuring a precise fit and effective tooth movement.
  • Comfort: Without metal brackets or wires, Invisalign reduces oral discomfort and the risk of irritation to the gums and cheeks.
  • Progress Monitoring: Invisalign’s treatment plan includes regular check-ups to monitor progress and make adjustments as necessary.

SmileFast, on the other hand, is a more recent entrant into the orthodontic treatment realm. It uses clear braces fixed to the teeth, combined with modern digital planning, to expedite tooth movement. While not as inconspicuous as Invisalign, SmileFast offers a quicker path to straight teeth for those who don’t mind visible braces.

  • Quick Results: Designed for speed, SmileFast significantly reduces treatment times, ideal for less complex dental alignment issues.
  • Digital Planning: Utilizes advanced 3D imaging for precise planning and execution of tooth movement.
  • Subtle Braces: Although more noticeable than Invisalign, SmileFast braces are less obtrusive than traditional metal braces.
  • Fixed Solution: Being non-removable, SmileFast braces work continuously on straightening your teeth, offering consistent pressure.
  • Cosmetic Focus: Primarily targets the “social six” – the front teeth that are most visible when you smile.

Comparing Invisalign and SmileFast: Advantages and Disadvantages

The pros and cons of each system vary depending on individual needs.

Invisalign Advantages

  • Aesthetics: Nearly invisible aligners make it a discreet option.
  • Hygiene: Easy to maintain oral health with the ability to remove aligners for cleaning your teeth and eating.
  • Comfort: Less irritation to gums and cheeks compared to braces.

Invisalign Disadvantages

  • Discipline Required: Requires commitment to wear the aligners for the recommended 22 hours a day.
  • Longer Treatment Duration: Typically takes longer than SmileFast, especially for complex cases.

SmileFast Advantages

  • Speed: Offers quicker results, with treatment times often shorter than Invisalign.
  • Cost-Effective: Generally more affordable than Invisalign.
  • Focused Treatment: Targets front teeth, providing cosmetic improvements in a shorter period.

SmileFast Disadvantages

  • Visibility: More noticeable than Invisalign’s clear aligners.
  • Limited Scope: Primarily cosmetic, may not be suitable for severe orthodontic issues.

Cost Breakdown: Invisalign vs. SmileFast

The cost of these treatments can vary depending on individual cases. Generally, Invisalign is perceived as a premium option, reflected in its pricing. SmileFast, offering quicker results, often comes in at a more budget-friendly price point.

  • Initial Consultation: Both treatments require an initial assessment to develop a personalized treatment plan.
  • Treatment Complexity: Costs can vary depending on the complexity of the patient’s dental issues.
  • Duration of Treatment: Longer treatment durations with Invisalign can contribute to a higher overall cost.
  • Technology Used: Invisalign’s advanced 3D imaging technology contributes to its cost.
  • Follow-up Care: Regular check-ups and adjustments are factored into the overall cost of both treatments.

It’s essential to consult with our specialists at Crestmead Dental for a tailored treatment plan and cost estimate.

Convenience and Comfort: Choosing Between Invisalign and SmileFast


  • Ease of Cleaning: Removable aligners make brushing and flossing much simpler, ensuring better oral hygiene.
  • Eating Habits: No dietary restrictions as aligners can be removed while eating.
  • Comfortable Wear: Custom fit reduces discomfort and irritation commonly associated with traditional braces.
  • Lifestyle Flexibility: Ideal for adults and teens who prefer a discreet solution that doesn’t interfere with social or professional engagements.
  • Speech Clarity: Minimal impact on speech, with most users adapting quickly to the aligners.
  • Less Frequent Dental Visits: Invisalign requires fewer adjustments than traditional braces, meaning fewer visits to the dentist.
  • Allergy-Friendly: Made from medical-grade thermoplastic, free from allergenic substances like latex.


  • Speed of Results: Designed for quick cosmetic improvements, particularly for the front teeth.
  • Less Maintenance: Being fixed, SmileFast requires less daily management than removable aligners.
  • Predictable Outcomes: Fixed braces offer a high degree of control over tooth movement, leading to predictable results.
  • Minimal Lifestyle Change: Except for some dietary adjustments, SmileFast requires less lifestyle alteration.
  • Visible Progress: With fixed braces, patients often notice changes and improvements more quickly.
  • Durability: Fixed braces are robust and less prone to damage or loss.
  • No Risk of Misplacement: Unlike removable aligners, there’s no risk of misplacing or forgetting to wear SmileFast braces.

In terms of convenience, Invisalign scores high. The ability to remove the aligners for eating and cleaning your teeth offers unparalleled comfort and hygiene. SmileFast, while fixed, is designed for comfort and minimal disruption to daily life.

Treatment Duration: How Long Does Invisalign and SmileFast Take?

Treatment duration is a critical factor in decision-making. Invisalign typically requires 12 to 18 months, depending on the extent of tooth movement needed. SmileFast, known for its efficiency, can deliver results in as little as 6 to 9 months.

Making the Right Choice: Invisalign vs. SmileFast for Your Needs

Your choice between Invisalign and SmileFast should consider your:

  • Severity of Misalignment: Invisalign is suitable for a wide range of alignment issues, including more complex cases.
  • Lifestyle Considerations: Invisalign aligners offer more flexibility and are less noticeable, fitting well with an active, social lifestyle.
  • Treatment Goals: SmileFast is ideal for those primarily concerned with cosmetic improvements in the front teeth.
  • Time and Commitment: Consider whether you prefer a shorter treatment time with SmileFast or the flexibility of Invisalign.
  • Budget Constraints: Invisalign tends to be more expensive due to the technology and customization involved.

Invisalign offers a long-term, flexible approach, ideal for comprehensive alignment issues. SmileFast is suited for those seeking quicker results and a more economical option.
