Clear Aligners for Sleaford Patients
Transform your smile discreetly with clear aligner treatment from St Mary's Dental, proudly serving Sleaford and the wider North Kesteven area of Lincolnshire. Modern clear aligner technology, including trusted systems like Invisalign, has revolutionised orthodontics, providing adults and teenagers with an almost invisible way to straighten teeth without the conspicuous appearance and inconvenience of traditional metal braces. Clear aligners are custom-engineered, transparent plastic trays that are precision-manufactured to fit your teeth perfectly. They apply gentle, controlled forces to gradually guide your teeth into optimal alignment. You'll progress through a personalised series of aligners, typically changing to a new set every two weeks. Each aligner moves your teeth slightly closer to their ideal positions, and over several months, you achieve a straighter, more confident smile that enhances your appearance. Unlike traditional fixed braces that are permanently bonded to your teeth 24/7, clear aligners are completely removable whenever you need. This provides significant lifestyle advantages for busy Sleaford residents - remove them for meals and drinks, so you can eat whatever you want without the dietary restrictions that come with fixed braces. You can also take them out for important work meetings, social occasions, or photographs, though for optimal results you should aim to wear them 20-22 hours per day. At St Mary's Dental, we utilise state-of-the-art 3D digital scanning technology to create a highly accurate virtual model of your teeth and bite. Our sophisticated treatment planning software then designs your complete orthodontic journey from start to finish, allowing us to show you a realistic 3D preview of your expected final results before you even commit to treatment. Throughout your aligner journey, we'll see you regularly to monitor your progress, ensure your teeth are moving correctly, and provide your next sets of aligners. Sleaford residents trust St Mary's Dental for our orthodontic expertise, personalised care, and proven track record in creating beautiful, life-changing smiles.
Benefits of Clear Aligners in Sleaford
Your Clear Aligners Journey
Free Initial Consultation
We'll thoroughly examine your teeth, bite, and jaw alignment, discuss your smile goals and orthodontic concerns, take diagnostic photos and X-rays, and assess whether clear aligners are the right orthodontic solution for your specific case.

Using advanced iTero or similar 3D intraoral scanning technology, we capture highly precise digital impressions of your teeth in minutes - a comfortable, quick process that eliminates messy traditional impression materials.
Personalised Treatment Design
We'll create your customised treatment plan using sophisticated software, designing a detailed 3D simulation that shows exactly how your teeth will move at each stage and what your final smile will look like.
Custom Aligner Manufacturing
Your complete series of aligners - the exact number depends on your case complexity - are manufactured using precision 3D printing technology for perfect fit and controlled, predictable tooth movement.
Begin Your Smile Journey
We'll fit your first set of aligners, demonstrate proper insertion and removal techniques, explain care and cleaning instructions, and provide your next several sets to change at home every two weeks.
Regular Progress Monitoring
You'll visit our practice every 6-8 weeks for check-up appointments where we monitor your progress, ensure your teeth are tracking as planned, address any questions or concerns, and provide your next batches of aligners.
Retention and Long-Term Care
Once treatment is complete, we'll provide custom retainers to wear (initially full-time, then typically at night) to keep your teeth in their beautiful new positions permanently.
Clear Aligners in Sleaford - FAQs
Treatment duration varies significantly based on your individual orthodontic needs and case complexity. Simple cases with minor crowding or small gaps might be completed in just 3-6 months. Average cases typically require 9-12 months of treatment. More complex situations involving substantial tooth movement, rotation, or bite correction may take 12-18 months or occasionally longer. During your free consultation at St Mary's Dental, we'll examine your teeth thoroughly and provide an accurate, personalised timeline estimate for your specific situation.
Clear aligners don't cause pain, but you'll definitely feel pressure and tightness when you start each new set - this is actually a positive sign that they're actively working to move your teeth! This sensation is typically strongest for the first 24-48 hours, then diminishes as your teeth begin adjusting. Most Sleaford patients find aligners significantly more comfortable than traditional metal braces, which often have sharp brackets and protruding wires that can irritate your cheeks, lips, and tongue.
For optimal results and to maintain your treatment timeline, you need to wear your clear aligners for 20-22 hours each day. Remove them only for eating, drinking anything except water, and your oral hygiene routine of brushing and flossing. Patient compliance is absolutely critical to treatment success - wearing aligners less than the recommended time will significantly slow your progress and may compromise the quality of your final results.
Yes! This is one of the major benefits over fixed braces. Simply remove your aligners before eating or drinking anything except water. This means absolutely no food restrictions - you can enjoy sticky toffee, crunchy apples, corn on the cob, popcorn, all the foods that are problematic or forbidden with traditional braces. Just remember to brush your teeth before reinserting your aligners to maintain good oral hygiene and prevent staining.
Modern clear aligner systems like Invisalign can effectively treat a wide range of orthodontic issues including crowding, gaps between teeth, overbites, underbites, crossbites, rotated teeth, and general misalignment. However, very severe or extremely complex cases may still require traditional fixed braces for optimal correction. We'll honestly assess your specific situation during your free consultation and advise whether clear aligners are suitable for your needs or if an alternative treatment approach would be better.
Contact our Sleaford practice immediately if you lose or damage an aligner. Depending on your treatment stage, we might advise moving forward to your next aligner in the series, reverting to the previous set temporarily, or ordering a replacement from the laboratory. Don't go for extended periods without wearing aligners as your teeth can shift back toward their original positions, potentially undoing weeks of orthodontic progress and delaying your treatment completion.
At St Mary's Dental, clear aligner treatment typically costs between £2,500 for straightforward cases and £5,500 for complex treatments requiring extensive tooth movement or bite correction. Most Sleaford patients invest £3,500-£4,500 depending on their individual orthodontic requirements. We offer flexible payment plans from £99 per month, including interest-free finance options, to make treatment accessible and affordable. Your free consultation includes a detailed personalised quote with complete transparency about all costs.
Yes, retainers are absolutely essential for maintaining your beautiful straight smile long-term. Once your teeth reach their ideal positions, they must be held there while the surrounding bone, periodontal ligaments, and gum tissues adapt and stabilise in the new arrangement. We include custom retainers as part of your treatment package at St Mary's Dental. Most patients wear them full-time initially (typically 3-6 months), then transition to nighttime-only wear indefinitely to ensure teeth remain perfectly straight for life.
