If you are researching how to fix overbite problems, here is the direct answer: most overbites are corrected with braces or clear aligners, often combined with small rubber bands (elastics) that guide the jaw into position. Mild cases may only need aligners or limited orthodontics, while severe overbites involving the jawbone can require jaw surgery alongside braces. Treatment typically takes 12–24 months, works at almost any age, and in the UK can be free on the NHS for under-18s with a qualifying clinical need.
This guide explains what causes an overbite, how orthodontists grade its severity, every treatment option in detail, how age affects the plan, and what it all costs privately in the UK.
What Is an Overbite, Exactly?
An overbite is when the upper front teeth overlap the lower front teeth more than they should. A small overlap of 2–3 millimetres is completely normal — in fact, a healthy bite needs some overlap so your teeth meet properly when you chew. Dentists usually only call it a problem when the overlap is excessive (a “deep bite”) or when it causes symptoms such as:
- Worn or chipped lower teeth from the uppers striking them
- Jaw pain, clicking, or headaches linked to a strained bite
- Difficulty biting into food cleanly
- Gum irritation where lower teeth bite into the palate
- Self-consciousness about the profile or smile
What Causes an Overbite?
Overbites usually develop from a mix of genetics and habits:
- Genetics: the size and shape of your jaw and teeth are largely inherited — if your parents had an overbite, you are more likely to have one.
- Thumb sucking and dummy use: prolonged sucking habits in childhood can push the upper teeth forward and narrow the palate.
- Tongue thrusting: pressing the tongue against the front teeth when swallowing can gradually move them.
- Teeth grinding: chronic grinding can wear teeth down and deepen the bite over time.
- Missing or crowded teeth: gaps and crowding change how the bite settles as the jaw grows.
Severity Levels: Mild, Moderate, or Severe?
Orthodontists measure the vertical overlap to grade the overbite, and the grade shapes the whole treatment plan:
- Mild (3–5 mm overlap): often mainly cosmetic. Clear aligners or a short course of braces usually fix it in 6–12 months.
- Moderate (5–8 mm): full braces or comprehensive aligner treatment, typically 12–24 months, usually with elastics to correct the bite relationship.
- Severe (8 mm+ or skeletal): when the jaw itself is misaligned rather than just the teeth, braces alone may not be enough — orthognathic (jaw) surgery combined with orthodontics may be recommended.
Your orthodontist will confirm the grade with X-rays and a cephalometric analysis that shows exactly where teeth and jaws sit.
Treatment Options for Fixing an Overbite
1. Traditional braces
Metal or ceramic braces remain the workhorse for overbite correction, especially moderate to severe cases. Brackets and wires straighten the teeth while elastics — small rubber bands you hook between upper and lower brackets — pull the bite into alignment. Treatment usually runs 18–24 months. If you are weighing up appliance types, our breakdown of how expensive braces are explains what drives the price of each option.
2. Clear aligners
Removable transparent trays can correct mild to moderate overbites very effectively, and many adults prefer them because they are nearly invisible and can be taken out for eating. Complex bite corrections may still need attachments (tiny tooth-coloured bumps) and elastics worn with the trays. Expect 12–18 months for a typical case.
3. Elastics (rubber bands)
Elastics deserve their own mention because they do much of the heavy lifting in bite correction. Your orthodontist prescribes a specific configuration and wearing schedule — often 20–22 hours a day. Patients who wear them faithfully finish months sooner; those who do not can stall treatment indefinitely.
4. Retainers and limited orthodontics
For very mild overbites in growing children, a removable appliance or a short phase of limited braces may be enough, sometimes followed by a retainer to hold the result. Retainers alone cannot fix an established adult overbite — they hold teeth in place but do not move them.
5. Jaw surgery (orthognathic surgery)
When the overbite is skeletal — meaning the upper jaw sits too far forward or the lower jaw too far back — surgery may be the only way to achieve a proper bite and balanced profile. The usual sequence is braces for 12–18 months to align the teeth, then surgery to reposition the jaw, then a few more months of braces to fine-tune. It sounds daunting, but it is a well-established procedure with high satisfaction rates for suitable cases.
Does Age Matter? Children, Teens, and Adults
- Children (7–11): an early orthodontic check can spot a developing overbite while the jaw is still growing. Sometimes a first phase of treatment guides jaw growth and makes later braces simpler — or unnecessary.
- Teenagers: the ideal window. The jaw is still growing, which the orthodontist can harness, and treatment tends to be fastest and most stable.
- Adults: teeth move at any age, so it is never too late. Treatment may take slightly longer, and severe skeletal cases are more likely to need surgery since growth is complete — but the vast majority of adult overbites are still fixed with braces or aligners alone.
Fixing an Overbite in the UK: NHS vs Private
On the NHS, orthodontic treatment — including overbite correction — is free for under-18s who meet the clinical threshold (assessed with the Index of Orthodontic Treatment Need). Moderate and severe overbites very often qualify. The trade-offs are waiting lists, which can run 12–24 months in some areas, and standard metal braces only.
Adults almost always go private, with typical UK costs of:
- Clear aligners for a mild overbite: £2,500–£4,500
- Full metal or ceramic braces: £2,500–£4,500
- Complex cases needing longer treatment: £4,000–£6,000+
- Jaw surgery cases: orthodontics as above, plus surgical costs which vary widely and are sometimes covered when medically necessary
Most private practices offer interest-free monthly payment plans. For an authoritative overview of what orthodontic treatment involves, see the NHS information on orthodontic treatment.
What to Expect During Treatment
- Consultation and records: examination, photos, X-rays, and impressions or a digital scan. You will get a written plan with the expected duration.
- Appliance fitting: braces go on in about an hour; aligner patients receive their first sets of trays with instructions.
- Regular adjustments: brace wearers visit every 6–8 weeks for wire changes; aligner wearers switch trays every 1–2 weeks and check in every 6–10 weeks.
- Elastics phase: once the teeth are roughly aligned, bite correction with elastics begins — this is where your compliance matters most.
- Retention: after the appliance comes off, retainers (fixed, removable, or both) hold everything in place. Teeth naturally drift throughout life, so long-term retention is essential.
Overbite FAQs
Can an overbite fix itself?
No. A true overbite does not self-correct — it usually stays the same or slowly worsens as teeth wear. Early intervention in children can redirect growth, but established overbites need treatment.
Will fixing my overbite change my face?
It can subtly improve your profile, especially in moderate to severe cases: the lips meet more naturally and the chin can appear less recessed. Braces move teeth, not bones, so the change is gentle; jaw surgery produces a more noticeable profile change.
Is overbite correction painful?
There is soreness for a few days after braces are fitted or tightened and when starting elastics, but most patients manage fine with over-the-counter pain relief and soft foods. WebMD’s overview of overbite correction is a useful second reference on what treatment feels like day to day.
How long do I need to wear a retainer afterwards?
Expect nightly retainer wear indefinitely — or at least for several years. Skipping retention is the most common reason corrected bites relapse.
The Bottom Line
Fixing an overbite is one of the most routine things orthodontists do: braces or clear aligners plus elastics handle the large majority of cases in 12–24 months, with jaw surgery reserved for severe skeletal problems. Start with an orthodontic consultation to get your severity graded, check NHS eligibility if the patient is under 18, and commit to wearing your elastics and retainers — they make the difference between a good result and a great one.
