Cfast Watford
CFast- Cosmetically Focussed Adult Straight Teeth

What is Cfast?

Cfast is a simple, gentle, minimally invasive cosmetic treatment that corrects alignment issues with the top and bottom front six teeth, and can level and round out the arches, thus satisfying the needs of the vast majority of adult patients who seek orthodontic treatment.

Cfast uses clear orthodontic brackets and tooth-colored nickel-titanium wires. The treatment works much like that using clear aligners, but tooth movement is much more predictable and usually more than twice as quick.

The nickel-titanium wires put gentle pressure on the brackets to level and align the teeth with minimal discomfort to the patient. The gingiva follows this movement to achieve a fully aesthetic outcome.

Cfast was develoed by Dr. Biju Krishnan in 2009. Dr. Krishnan qualified from Dundee University in 1993 and after several years in general practice completed a clinical attachment in Oral Surgery in 1999.

Dr. Krishnan lectures nationally and internationally, primarily on short-term adult orthodontics, in which he has pioneered new concepts using the Cfast System. He is also on the editorial board of Aesthetic Dentistry today.


Q. Cfast sounds too good to be true - what's the catch?

A. There isn't one. Cfast is a fast, effective and affordable treatment when adult patients are seeking to correct their smiles. Because it does not claim to address major orthodontic issues, Cfast can be done very quickly, making it more affordable than most other orthodontic options.

Q. How can Cfast straighten the teeth in such a short time?

A. Cfast takes less time because it focuses only on the "social six", the front teeth that most influence the smile. The process is further enhanced with the use of special nickel-titanium wires, which exert gentle pressure to force movement in the teeth.

Q. Braces are unpopular with adult patients. Isn't it the same with Cfast?

A. No. With its clear brackets and tooth-colored wires, Cfast is barely noticeable - and they're worn for a fraction of the time compared to traditional braces.

Q. Normal braces can be very uncomfortable for the patient. Is Cfast?

A. Standard orthodontic mechanics are still involved, but because it's just the front teeth, the force required is minimal. The nickel-titanium wire exert mild pressure to force the teeth to move, and this is done without the need for severe tightening.

Q. Is a retainer necessary at the end of treatment?

A. Yes. Like all tooth-straightening treatments, the gain of Cfast may be lost if a retainer is not worn. The patient can choose between a removable retainer and a permanently bonded retainer. The choice depends on preference and the individual case.
