When use continues beyond ages two to three, prolonged pressure on developing teeth and jaws can alter the bite in predictable ways. This guide explains what changes occur, how they compare with thumb sucking, when self-correction is likely, and what parents should do if habits persist.

A dummy placed between the teeth acts as a physical barrier that prevents the front teeth from erupting fully and applies lateral pressure to the upper arch. The most characteristic effect is an anterior open bite — the upper and lower front teeth no longer touch vertically because the dummy has occupied the space between them. Alongside this, the sustained cheek muscle pressure without adequate tongue counter-pressure narrows the upper arch, producing a posterior crossbite in which the upper back teeth occlude inside the lower. Overjet also tends to increase as the upper labial segment is pushed forward. These effects are dose-dependent: the longer each day the dummy is used and the older the child when the habit stops, the more pronounced the dental changes become. ## Do NUK and orthodontic dummies cause fewer dental problems? Orthodontic dummies — most commonly associated with the NUK brand — have a flattened teat with a bulbous tip designed to mimic the shape of a compressed nipple during feeding. The rationale is that this shape distributes pressure more evenly and allows the front teeth to approach each other more naturally than a round or cherry teat. There is some evidence that orthodontic dummies produce less severe anterior open bite than round teats and a marginally lower incidence of posterior crossbite. However, the difference is modest and prolonged use of any dummy design beyond age two to three still carries orthodontic risk. ## How do dummies compare to thumb sucking for dental effects? From an orthodontic perspective, dummies and thumb sucking produce broadly similar patterns of malocclusion — anterior open bite, posterior crossbite, and increased overjet. The key advantage of the dummy over the thumb is that it is an external object that can be removed or restricted by the parent. Thumb sucking, by contrast, is a behaviour generated by the child and is harder for parents to control, particularly when it occurs during sleep. Weaning a child from a dummy is generally more achievable than breaking a thumb-sucking habit. NHS guidance consistently advises stopping dummy use by age one for general health reasons and no later than age two to three to protect dental development. ## When does self-correction occur after stopping dummy use? The teeth and jaws of young children are highly adaptive. If the dummy habit stops before the permanent teeth begin to erupt — typically before age six to seven — the bite changes are often largely or completely reversible without treatment. The tongue returns to normal palatal position, the front teeth erupt downward to close the open bite, and the crossbite may narrow or fully resolve. Self-correction is most reliable when the habit stops before age seven. After this age, once permanent teeth are erupted, spontaneous correction becomes less predictable and residual malocclusion is more likely to require orthodontic intervention. ## What strategies help with dummy weaning? Health Visitors and the NHS recommend a gradual approach to dummy weaning. Starting by restricting dummy use to sleep times only — removing it from daytime use first — reduces exposure without abrupt removal. From there, limiting it to nighttime only and then removing it entirely is a staged approach that many children tolerate well. The dummy fairy — a narrative in which the child gives their dummy away to babies who need it — is a widely used behavioural strategy that works well for children aged two to three. Reward charts combined with positive reinforcement can also be effective for older children. Where a child is using a dummy primarily to manage anxiety, addressing the underlying cause alongside the weaning plan improves success rates. ## What orthodontic treatment is available when self-correction has not occurred? Children whose bite does not fully self-correct after stopping dummy use, or who used a dummy beyond age seven, will be assessed by an orthodontist. Common findings requiring treatment include a persistent anterior open bite, posterior crossbite — particularly when associated with a functional shift of the lower jaw — and upper arch constriction. In growing children, palatal expansion using a removable or fixed expander can widen the upper arch and correct the crossbite. Functional appliances or conventional fixed braces address the open bite and overjet. NHS orthodontic treatment is available to under-18s meeting the IOTN threshold. ## Useful related pages [Thumb Sucking and Orthodontics](https://virtualconsultant.online/guides/thumb-sucking-digit-habit-orthodontics-uk) [Children's Orthodontics UK](https://virtualconsultant.online/guides/childrens-orthodontics-uk) [Interceptive Orthodontics UK](https://virtualconsultant.online/guides/interceptive-orthodontics-uk) [Crossbite Treatment UK](https://virtualconsultant.online/guides/crossbite-treatment-uk) [Functional Appliances UK](https://virtualconsultant.online/guides/functional-appliances-uk) This guide is for general information only.

NHS guidance and UK Health Visitors recommend stopping dummy use by age one for general health reasons including ear infection risk. To protect dental development, the guidance is to stop no later than age two to three. The earlier the dummy is removed, the greater the chance of full self-correction of any bite changes without orthodontic intervention. If the habit continues beyond age three despite parental efforts, discussing this with a Health Visitor or GDP is a good next step. Can dummy use cause a permanent open bite? Dummy use beyond age six to seven can produce an anterior open bite that does not fully self-correct once the habit stops, because permanent teeth begin to settle into the space left by the dummy. A persistent open bite after the habit has stopped, particularly in a child aged over seven, is likely to require orthodontic treatment. If the habit stopped before age six to seven, significant spontaneous improvement is usually seen over the following six to twelve months. Are orthodontic dummies like NUK safer for teeth? Orthodontic dummies produce a somewhat lower risk of anterior open bite and posterior crossbite compared with round teats, because their flattened shape exerts more even pressure. However, the difference is modest and prolonged use of any dummy beyond age two to three still carries orthodontic risk. Choosing an orthodontic dummy is sensible, but timely weaning remains the most important step in protecting dental development. Is a dummy worse than thumb sucking for teeth? The bite changes — anterior open bite, posterior crossbite, and increased overjet — are broadly similar between dummy and thumb habits. The main advantage of the dummy is that it is an external object parents can remove or phase out, making weaning generally easier and more controllable. A thumb habit is harder to control because it is self-generated and often occurs unconsciously during sleep, making it more difficult for parents to intervene consistently. What happens if my child will not give up the dummy? If a child has a persistent dummy habit beyond age three to four despite parental efforts, it is worth discussing with your Health Visitor, who can provide structured weaning advice. For children with an established dummy habit at age seven or older, an orthodontic referral from your GDP is appropriate. The orthodontist will assess bite changes and advise whether habit-breaking intervention, monitoring, or active orthodontic treatment is needed. Will the NHS treat open bite caused by dummy use? NHS orthodontic treatment is available to under-18s who meet the IOTN treatment threshold. An anterior open bite or crossbite resulting from prolonged dummy use may qualify for NHS treatment if it scores at IOTN grade 4 or 5. A referral from your GDP is the first step. Some interceptive treatments in younger children — such as palatal expansion — may also be provided within the NHS framework where clinical need is met. Mild residual changes that do not reach the treatment threshold may not qualify for NHS-funded orthodontics. How long does self-correction take after stopping the dummy? Most bite improvement following cessation of dummy use occurs within six to twelve months. The speed and extent of self-correction depends on the age at which the habit stopped and the severity of the changes. Younger children — under age six — show the most rapid and complete improvement. An orthodontist or GDP will usually monitor a child for at least a year after the habit stops before deciding whether active treatment is needed, to allow adequate time for natural improvement.
