Six month smiles vs Invisalign: what is the difference?

For adults looking to straighten their front teeth without a long treatment commitment, six-month smiles and Invisalign are two options that often come up in the same conversation. Both are designed with the adult patient in mind. Both can produce meaningful results in a shorter timeframe than traditional fixed braces. But they work differently and suit different clinical situations.

What are six month smiles?

Six Month Smiles is a fixed brace system that uses clear brackets and tooth-coloured wires to make the appliance less visible than conventional metal braces. It is designed primarily to align the front teeth visible in the smile zone in an accelerated timeframe, typically three to nine months for most cases.

The accelerated nature of six-month smiles comes from its focus. Rather than addressing the full orthodontic picture, including the bite and the position of back teeth, it concentrates on the cosmetic alignment of the front teeth. It does not perform complex bite correction.

What is Invisalign?

Invisalign uses a series of clear, removable aligners to straighten teeth. Unlike fixed braces, the aligners can be taken out for eating, drinking, and cleaning. They are virtually invisible when worn.

Invisalign can address a wider range of orthodontic issues than six-month smiles, including overbites, underbites, crossbites, and more significant crowding. Treatment times vary from three months for minor corrections to 24 months or more for complex cases.

At Berkhamsted Dental, Dr Kishan Lakhani is ranked among the top 150 Invisalign providers in the world, with thousands of successful cases completed.

Key differences

Visibility. Six Month Smiles uses clear brackets and wires, which are less visible than metal but still noticeable. Invisalign aligners are virtually invisible.

Removability. Six Month Smiles is fixed for the duration of treatment. Invisalign aligners come out for meals and oral hygiene.

Scope. Six Month Smiles is primarily a cosmetic alignment solution for the front teeth. Invisalign can address a wider range of concerns, including bite issues and significant crowding throughout the arch.

Dietary restrictions. With Six Month Smiles, certain foods should be avoided. With Invisalign, there are no restrictions because the aligners are removed for eating.

Which is right for you?

If your primary concern is the alignment of your front teeth, your back teeth are in good functional position, and you are comfortable with a fixed appliance, six month smiles may be suitable.

If you want a removable, near-invisible appliance or need to address bite issues alongside alignment, Invisalign is likely the better fit.

The definitive answer requires a clinical assessment. Book a consultation at Berkhamsted Dental to find out which approach is right for your teeth and your goals.

    Very happy with my Invisalign process with Kish. He kept me well informed throughout and always took time to answer all my many queries. The price was reasonable compared to others in the area and it has all been completed within the original time advised. I'm yet to have my composite bonding done but hope to have a transformed smile in the end. Would thoroughly recommend BDP if you're considering Invisalign.

    I have just completed the main part of my Invisalign journey followed by composite bonding and could not be happier. Having been told by my previous dentist that it wasn’t worth doing ( due to my age and small change I would achieve) I had a consultation with Dr Kish to start a programme of Invisalign to straighten out my front teeth which had moved over time and now had a very slight overlap. Once complete, I saw Dr Ventsi for bonding to the edges of 6 teeth, which, as a heavy tooth grinder, were chipped and uneven. Both Drs were knowledgeable and lovely to deal with. I could not be happier with the result! A little change has made a huge difference !
