Yes, your teeth can shift as you get older. Changes to your teeth, gums and supporting structures can contribute to gradual movement throughout adulthood. Previous orthodontic treatment doesn’t necessarily prevent future movement either, particularly if retainers aren’t worn as recommended.
If you’ve noticed new gaps, crowding or changes to your bite, there may be several reasons why. Below, we explain why teeth can shift in adulthood, when you should seek advice and what treatment options may be available.
Why Do Teeth Shift as You Age?
It’s common to notice changes in your teeth as you get older, even if they were once straight. If you’ve noticed increasing crowding, new gaps or changes to your bite, there may be several reasons why. Below, we explain why teeth can shift in adulthood and when it may be worth speaking with a Specialist Orthodontist.
1. The Ageing Process
Teeth aren’t permanently fixed in one position. As you age, changes can occur in your teeth, gums, jaw and the structures supporting your teeth. Over time, these changes can contribute to gradual movement and crowding, which is often particularly noticeable around the lower front teeth.
2. Teeth Grinding and Clenching
Many adults grind or clench their teeth, often without realising it, especially while asleep. This pressure places significant strain on the teeth and jaw, which can contribute to unwanted movement and alignment issues.
3. Tooth Loss
When a tooth is lost or extracted and not replaced, adjacent teeth may begin to move into the space. This can result in changes to your bite and overall alignment, especially if left unaddressed over time.
4. Gum Disease
Advanced gum disease affects the supporting structures of the teeth, including the bone and connective tissues. As these foundations weaken, teeth may become loose or begin to shift from their original positions.
5. Everyday Habits
Small, repeated behaviours such as nail-biting, chewing on objects, or sleeping consistently on one side of your face can apply uneven pressure on the teeth and contribute to gradual movement.
6. Not Wearing Your Retainer
Can Shifted Teeth Be Straightened Again?
If your teeth have shifted, orthodontic treatment may be an option depending on the cause and extent of the movement, as well as your oral health.
Treatment options for adults may include clear aligners or braces. Before recommending treatment, a Specialist Orthodontist will assess your teeth and bite and consider factors such as your dental history, gum health and treatment goals.
In some cases, other dental or periodontal treatment may need to be addressed before orthodontic treatment begins. Our orthodontists will let you know if this is required for your smile.
FAQ
Do teeth naturally shift as you get older?
Some gradual movement can occur throughout adulthood as your teeth and their supporting structures change over time.
Why are my bottom teeth becoming crooked?
Crowding of the lower front teeth can become more noticeable with age. Several factors can contribute, so an orthodontic assessment can help identify what’s happening in your individual case.
Why are my teeth shifting after braces?
Teeth can move after orthodontic treatment, particularly when retainers aren’t worn as recommended. Long-term retainer wear helps maintain tooth position.
Can teeth shift even if you’ve never had braces?
Yes. Teeth can gradually change position throughout life regardless of whether you’ve previously had orthodontic treatment.
Can shifted teeth be straightened again?
In many case, yes. Depending on your oral health and the type and extent of movement, braces or clear aligners may be suitable. An orthodontic assessment is required to determine which treatment options are suitable for your smile.
