Straightening teeth is both a technical process and a creative one. The science lies in the precision: clear aligners are digitally designed to apply gentle, consistent pressure, moving your teeth into their ideal positions with millimetre accuracy.
The art is in creating a smile that suits your face and feels authentic to you. Teeth can be aligned in countless ways, but the best results are those that balance symmetry, proportion, and personality. We consider the shape of your lips, the curve of your smile, and how your teeth show when you speak or laugh, so the end result is truly yours.
Book AppointmentFor patients searching for Invisalign in Prestons, Spark clear aligners deliver comparable results with unique advantages in clarity, comfort, and fit. While both products offer the same benefits, there are a few distinctions worth noting.
Both Invisalign and Spark use a series of custom-made trays to gradually guide teeth into their ideal positions, but Spark aligners are made from TruGEN™ material, which are renowned for its exceptional clarity. Furthermore, their precision-trimmed edges are designed for a smoother, more comfortable fit, which reduce the risk of irritation.
Spark’s advanced 3D treatment planning software allows for highly accurate movement mapping, and the aligners are designed to apply consistent, gentle pressure for predictable results. Many patients also appreciate that Spark aligners are less prone to discolouration, which can make a big difference during longer treatments.
Our principal dentist chose Spark clear aligners after careful consideration, selecting them for their comfort, clarity, and precision, and ultimately putting patient experience at the heart of every decision. We invite you to discover the difference they could make in your journey to a straighter smile.

Clear aligner pricing depends on the complexity of your case and how long treatment will take. Shorter, minor adjustments typically cost less, while more complex cases require more aligners and time.

Clear aligners such as Invisalign and Spark Aligners that we use are a series of custom-made trays that apply gentle pressure to gradually move your teeth into their ideal positions. Each set is worn for 20–22 hours a day over a prescribed period before moving on to the next. Your progress will be monitored by our dentists at regular check-ins.
Clear aligners are suitable for adults who want to straighten their teeth without traditional braces. They’re effective for mild to moderate crowding, gaps, and certain bite issues such as overbites and crossbites. Successful treatment depends on your dedication: you’ll need to wear your aligners as directed and maintain excellent oral care throughout your orthodontics journey.
Treatment time with clear aligners varies depending on the complexity of your case. Minor adjustments can take as little as 6 months or less, while more comprehensive orthodontic corrections may take 12–18 months. At your consultation, we’ll assess your smile and provide a personalised timeline so you know exactly what to expect from your clear aligners in Prestons.
