What causes crooked teeth
The most common cause is crowding: the jaw is a little too small for the teeth that need to fit in it, so some tilt, twist or overlap. Jaw and tooth size are largely inherited, which is why crooked teeth run in families.
Habits in childhood add to it. Long-term thumb sucking, dummy use and tongue thrusting push teeth out of position. Losing a milk tooth early, from decay or injury, lets neighbouring teeth drift into the gap so the adult tooth has no room to come through. Our guide on adult teeth coming in behind milk teeth covers one common result.
Extra teeth, a narrow upper jaw and teeth that are missing or stuck can also upset the line. Injury and old gum disease can move teeth later in life.
Do crooked teeth cause problems, or is it just looks?
Many people have mildly crooked teeth with no trouble. But overlapping teeth are harder to clean, so plaque and tartar collect in the tight spots and cavities and gum disease become more likely. Teeth that do not meet properly can also wear unevenly or strain the jaw muscles in some people.
Looks matter too. Wanting a more even smile is a perfectly good reason to straighten teeth, and confidence is a real benefit. The point is that treatment is not only cosmetic.
How crooked teeth are straightened
Braces move the actual teeth and work for mild to severe crowding, in children, teenagers and adults. See the pillar page on braces and orthodontics for what treatment involves. Clear aligners are removable trays that suit milder cases; our comparison of clear aligners vs braces explains how to choose.
Veneers cover the front of a tooth and can hide a small twist or gap, but to make crooked teeth look level the dentist has to remove healthy enamel, which does not grow back. The trade-offs are set out in veneers vs braces. Veneers are never a substitute for moving teeth in anything beyond a minor case.
Adults are not too old; the main requirement is healthy gums. Read braces for adults for the details. Retainers afterwards keep the result, as covered in the guide on retainers after braces.
| Option | What it does | Best suited to |
|---|---|---|
| Fixed braces | Move teeth with brackets and wire | Mild to severe crowding and bite problems |
| Clear aligners | Move teeth with removable trays | Mild to moderate cases and patients who wear them reliably |
| Veneers | Cover the tooth surface to hide small irregularities | Very minor cases where moving teeth is not needed |
General comparison of ways to treat crooked teeth. A dentist decides what suits your case.
When to get crooked teeth checked
A first check around age 7 to 8 is sensible for children, because some problems are easier to guide while the jaws are growing; the details are in our guide on the best age for braces. Adults who notice teeth shifting, new crowding in the lower front teeth, or difficulty cleaning between teeth can be assessed at any age.
Common questions
Can crooked teeth straighten on their own?
Almost never. Mild gaps in young children can close as adult teeth come in, but true crowding and rotation do not correct themselves and tend to get slightly worse over time.
Are crooked teeth unhealthy?
Not automatically. They are harder to clean, though, so plaque builds up and cavities or gum problems are more likely if cleaning is not thorough. Good brushing and interdental cleaning keep crooked teeth healthy.
What is the fastest way to straighten crooked teeth?
There is no instant method that moves teeth safely. Braces and aligners both need months, and the time depends on the case. Be wary of anyone who promises results in a few weeks.
Can crooked teeth be fixed without braces?
Only minor irregularities can be hidden with veneers or reshaping, and that involves removing some enamel. Moving teeth into the right position needs braces or aligners.
