What is malocclusion?
Malocclusion means teeth that are not properly aligned, says MedlinePlus (US National Library of Medicine). Its three classes are a normal bite but upper teeth slightly over the lower (Class 1, the most common), upper jaw and teeth severely overlapping the lower (Class 2), and the lower jaw jutting forward (Class 3).
Which problem sounds like yours?
Crowding, too little room for the teeth, may come from a narrow jaw, the British Orthodontic Society (BOS) says. MedlinePlus says correcting moderate or severe malocclusion can make teeth easier to clean. Read about crowded teeth.
Spacing means significant gaps between the teeth, BOS notes, and the NHS says large gaps may need braces. See gaps and spacing between teeth.
A deep overbite is when the upper teeth cover the lower too much, which BOS calls a deep bite. If the bite injures your gum or palate, show it to a dentist. Read about an overbite.
An underbite is a Class 3 bite, with the lower jaw jutting forward, MedlinePlus explains. If it makes chewing or speaking difficult, show it to a dentist. Read about an underbite.
A crossbite is when upper teeth bite inside the lower, which BOS calls a reverse bite. If your jaw shifts to bring the teeth together, show it to a dentist. Read about a crossbite.
An open bite is when the front teeth stay apart while the back teeth meet, BOS explains. If it stops you biting into food properly, show it to a dentist. Read about an open bite.
Protruding upper front teeth are among the most common problems, BOS says. A 2015 review of 54 studies across ages linked a large overjet with about double the odds of front-tooth injury; if yours stick out, see a dentist. Read about protruding front teeth.
Relapse means teeth drifting back towards their original positions after orthodontic treatment, BOS explains; if yours have moved, show them to a dentist. Read about teeth that moved after braces.

What does this section cover?
This section covers malocclusion and relapse; for treatments, see the options in the treatments section. The aligner section asks whether aligners can correct a bite, and our guide orthodontic treatment explained and our page on straightening teeth give the wider picture.
Who is orthodontic treatment for at the practice?
At Deepcar Dental Care, our dentists provide orthodontic treatment for adults only. Mild to moderate crowding and spacing are among the problems treated, alongside bite correction. Extraction and complex cases are assessed case by case; some need braces or a combined approach. Unsure what might suit? See choosing a treatment.
Frequently asked questions
Do all bite and alignment problems need treatment?
No. MedlinePlus says very few people have ideally aligned teeth, and most problems are minor and need no treatment. It says correcting moderate or severe malocclusion can eliminate strain on the teeth, jaws and muscles, lessening the risk of breaking a tooth. A dentist can check yours.
How is the need for orthodontic treatment graded?
With the Index of Orthodontic Treatment Need (IOTN), set out for adult teeth in an NHS England guide. Grade 3 is borderline need, and grades 4 and 5 need treatment. A deep overbite that injures the gum or palate, for example, is grade 4.
Can a bite problem develop in adulthood?
Yes. The British Orthodontic Society says teeth may start to move unpredictably later in life, often showing some crossing over and more crowding, and MedlinePlus lists lost teeth and ill-fitting dental work as causes. If your teeth are moving, show them to a dentist.
