Twisted, overlapped or rotated teeth can be straightened with Invisalign or traditional braces - a tailored plan built around your smile by Dr Chaw-Su Kyi.
Crooked teeth are typically caused by an overcrowded mouth, which results in teeth that are twisted, overlapped, angled, rotated and misaligned. Although uneven teeth are unique and can be a charming and defining aspect of a distinctive smile, it is perfectly understandable to want to have them straightened. If you are not happy with the way your teeth look, or they are causing oral health problems, they can be straightened with a variety of orthodontic treatments that include Invisalign® aligners and traditional braces.
Invisalign is an effective and simple way of creating a straight smile with clear aligners that fit over the teeth. Virtually invisible, the treatment consists of wearing a series of aligners that gradually move the teeth into their correct positions.
As a renowned specialist in orthodontics, Dr. Chaw Su Kyi offers unparalleled expertise with crooked teeth treatment in London. Her tailor-made treatments can help you achieve a straight smile that looks good, as well as reduce the risk of malocclusion and other related oral health problems.

Having straight teeth is not just about aesthetics; it also boosts your confidence and improves oral health. But what if your teeth aren’t well aligned? Moreover, how can an orthodontist address these issues? Let’s look at the common orthodontic problems and how they are treated.

We understand that orthodontic issues come in different shapes and sizes. That’s why Dr. Kyi and the team offer several orthodontic treatments to suit various needs. After an in-depth examination, we’ll devise a personalised treatment plan. Our services include traditional braces, which provide an affordable and effective solution for mild to severe orthodontic problems. We also offer Invisalign orthodontics for patients with mild to moderate dental issues who are insecure about metal braces.

The most challenging cases often involve severe misalignment, complex jaw irregularities, or congenital issues like cleft palate. Deep overbites, crossbites, or severe crowding requiring extractions are also complex. For adults, tooth movement and jaw alignment issues can be more difficult due to mature bone structures. Cases needing both orthodontic and surgical intervention, like orthognathic surgery, are particularly demanding, requiring a multi-disciplinary approach and extended treatment timelines.
Orthodontic problems stem from genetic and environmental factors. Genetics play a substantial role, with crowding, spacing, overbites, underbites, and jaw misalignment often inherited. Environmental factors, especially during childhood, also contribute. Prolonged thumb-sucking, dummy use, mouth breathing, and early loss of primary teeth can all disrupt natural development, leading to misaligned bite (malocclusion) and other issues needing orthodontic treatment.
Orthodontic treatment can occasionally encounter complications, but with a qualified orthodontist, these risks are minimised. Issues include prolonged treatment times, gum recession, and enamel wear from braces. If orthodontic appliances are not maintained, tooth decay or staining around brackets may occur. Misalignment due to poor planning or not following the post-treatment care (like wearing retainers) may cause teeth to shift back. It’s crucial to choose an experienced orthodontist and follow their guidance closely.
A crowded mouth appears when teeth overlap or appear messy because there isn’t enough space to align the jaw. This pushes some teeth forward, backward, or causes them to rotate to fit. Crowded teeth may create tight spaces that are difficult to clean, increasing decay and gum disease risk. A crowded mouth looks uneven, with some teeth visibly out of line.
If untreated, orthodontic issues can lead to oral health problems. Misaligned teeth and jaws increase the risk of decay, gum disease, and difficulty chewing, which can strain the jaw muscles. Malocclusion can cause tooth wear, enamel damage, and temporomandibular joint (TMJ) disorders in severe cases. Untreated problems can also affect self-confidence, especially regarding smile appearance.
Braces can cause complications, including soreness after adjustments, irritation to the gums or inner cheeks, and broken brackets or wires from eating hard or sticky foods. Poor oral hygiene can lead to plaque buildup, increasing cavities and gum disease risk. Some patients may experience enamel demineralisation around braces. Regular orthodontic check-ups help mitigate these problems.
The most common treatment is traditional metal braces. Metal braces are effective for correcting crowding, spacing, and alignment. Other popular treatments include clear aligners like Invisalign, which adults and teens favour for their discreet appearance. Metal braces offer more control in complex cases, while clear aligners provide convenience and aesthetic appeal for mild to moderate misalignment.
