Crooked teeth: causes and treatment options for adults

If your teeth overlap, have gaps or do not meet comfortably, a dental assessment can help you understand the cause and your options. You may want to change their appearance, make cleaning easier or improve your bite. Treatment should address your own concerns, rather than an expectation that every smile needs to look the same.

Why do teeth become crooked?

Tooth size, jaw size and the way the bite develops all play a part. Losing a milk tooth early can sometimes reduce the space available for an adult tooth. A retained milk tooth may also need assessment if it obstructs eruption, but a loose or decayed milk tooth does not automatically need extraction.

Tooth position can change in adulthood too. Teeth may move around a gap or after orthodontic treatment, particularly without the recommended retainer wear. New movement, loose teeth or a changing bite should be checked by a dentist.

Wisdom teeth should not simply be blamed for pushing all the front teeth together. Removing them is not a routine solution to crowding. Their condition and any reason for removal need a separate assessment.

Does crowding always cause health problems?

Crowded areas can be difficult to clean, and some bite problems affect chewing or cause uneven wear. The effect depends on the individual teeth and bite. Crooked teeth do not inevitably lead to decay, gum disease, speech problems or weak enamel.

The dentist checks oral health as well as alignment. Decay and gum disease need attention before orthodontic treatment, and good cleaning remains important during it. Straightening teeth is not a substitute for looking after them.

For children, routine dental care allows the dentist to monitor development and refer when appropriate. Our guide to crooked teeth in children explains why some changes need observation and others need earlier advice.

Braces are an option for adults too

Age alone does not rule out orthodontic treatment. The condition of the teeth, supporting tissues and bite matters, along with the movement needed. Treatment time varies; it is not simply a question of adults having harder bones.

Options can include fixed metal or tooth-coloured braces, braces fitted behind the teeth, and clear aligners. They are not interchangeable, and not every option is suitable for every bite. Removable appliances must be worn as prescribed, rather than taken out whenever convenient.

The NHS braces guide explains assessment and care. Ask about the expected changes, limitations, cleaning, reviews and retainers before agreeing to treatment.

What about veneers?

A veneer covers the front of a tooth and can change its visible shape. It does not move the tooth or correct the way the jaws meet. Preparing a tooth for a veneer may remove healthy tissue, so it is worth discussing whether orthodontics or a smaller bonded repair would better address your concern.

A dentist can help you compare the amount of treatment, risks and maintenance involved. There is no need to choose a restoration simply because you feel too old to wear braces.

Planning the cost

Ask for a written estimate covering the proposed course of treatment and follow-up. See our orthodontic fees and current finance information. Contact the practice to arrange an assessment and discuss what you would like to change.
