Teeth straightening has become one of the most sought-after dental treatments in the UK. Whether you are a teenager dealing with crowded teeth or an adult who has always wished for a straighter smile, the options available today are more varied, effective, and discreet than ever before. This guide examines every route to a straighter smile so you can make a fully informed decision.
Why Consider Teeth Straightening?
Misaligned teeth are not just a cosmetic concern. Crooked or crowded teeth can trap food, making them harder to clean and increasing the risk of decay and gum disease. A poor bite (malocclusion) can also cause jaw pain, uneven tooth wear, and difficulties with speech. Beyond the functional benefits, studies consistently show that people who are happy with their smile report higher self-confidence in social and professional settings. According to the British Orthodontic Society, demand for adult orthodontics has risen by more than 80% over the past decade.
Types of Braces and Aligners
Fixed metal braces remain the gold standard for complex orthodontic cases. They use brackets bonded to each tooth connected by an archwire, which your orthodontist tightens at regular appointments. Ceramic braces work the same way but use tooth-coloured or clear brackets for a subtler appearance. Lingual braces are fitted behind the teeth, making them virtually invisible from the front, although they tend to be more expensive and can take some adjustment. Clear aligners such as Invisalign use a series of custom-made, removable trays that gradually shift teeth into position. They are popular with adults because they are nearly invisible and can be removed for eating and cleaning.
NHS vs Private Treatment
The NHS provides orthodontic treatment for children and young people who meet certain clinical criteria assessed using the Index of Orthodontic Treatment Need (IOTN). Adults are rarely eligible for NHS-funded braces. Private treatment costs in the UK range from around £1,500 for simple aligner cases up to £7,000 or more for complex lingual braces. Many practices offer interest-free payment plans to spread the cost.
Treatment Timelines and Aftercare
Simple aligner treatments can produce results in as little as three to six months. More complex cases involving fixed braces typically take 12 to 24 months. Regardless of the method, you will almost certainly need to wear a retainer after treatment to prevent teeth from shifting back. Retainers may be removable (worn nightly) or fixed (a thin wire bonded behind the front teeth). Your orthodontist will advise on the best option based on your case.
How to Choose the Right Provider
Always check that your provider is registered with the General Dental Council (GDC). Orthodontic specialists have completed additional postgraduate training beyond a general dental degree. During a consultation, ask about the proposed treatment plan, expected timeline, total cost including retainers, and what happens if the results are not as expected. A reputable provider will be happy to answer all your questions before you commit.
