If you’ve been considering straightening your teeth but want to avoid traditional braces, clear aligners offer a modern, discreet alternative. At Markham Associates Dental Practice in Reading, we provide 6 Month Smiles, a fast and effective aligner system designed to give you a straighter smile in as little as six months.
But how do teeth aligners work? And are they right for you? Here’s everything you need to know.
What are teeth aligners?
Teeth aligners, often called clear aligners, are removable, nearly invisible trays that gently guide your teeth into a more aligned position. Unlike metal braces, aligners contain no wires or brackets, making them comfortable, discreet, and easy to clean.
At Markham Associates, we use the 6 Month Smiles short-term orthodontic system, which combines proven orthodontic techniques with clear aligners to deliver fast, predictable results.
How do teeth aligners straighten teeth?
1. Consultation and Digital Smile Assessment
Your treatment begins with a consultation at our Reading practice. During this visit, we take digital scans, photographs, and discuss your smile goals. This information is used to create your 3D treatment plan, showing how your teeth will move throughout the process.
2. Custom-Made Aligners
Once your treatment plan is finalised, a series of custom-made 6 Month Smiles aligners is created to fit your teeth perfectly. Each aligner applies gentle, consistent pressure, guiding your teeth into better alignment.
3. Gradual, Controlled Movement
You will wear each set of aligners for 1–2 weeks, depending on your personalised plan. Each aligner moves the teeth slightly, usually around 0.2–0.3 mm, until your smile reaches its final, improved position.
To achieve the best results, aligners should be worn 20–22 hours per day, removing them only for eating, drinking (except water), brushing, and flossing.
4. Attachments and Precision Enhancements
For some patients, small, tooth-coloured “attachments” may be placed on certain teeth to improve grip and control. These are subtle and help the aligners achieve more complex movements when needed.
5. Final Refinements and Retainers
Once your main aligner series is complete, we may recommend a few refinement aligners to perfect the final details of your smile.
At the end of treatment, retainers are essential. They help maintain your results and prevent teeth from shifting back over time.
What can 6 month smile aligners fix?
6 Month Smiles aligners can correct a wide range of mild to moderate orthodontic issues, including:
- Crowded teeth
- Gaps between teeth
- Mild overbite or underbite
- Rotated teeth
- Slightly crooked front teeth
This makes them an ideal option for adults and teens looking for a fast, discreet way to improve their smile.


How long does it take to straighten your teeth with 6 month smiles?
As the name suggests, 6 Month Smiles often delivers results in around six months, although treatment times may vary depending on the complexity of your case.
During your consultation at Markham Associates Reading, we will give you a clear idea of your expected timeline.
