Notice anything different about your smile lately? Maybe a gap that wasn't there before? Some new sensitivity or discomfort? If so, it could be a sign that your teeth are shifting. Many people don’t realize it, but teeth-shifting happens to everyone. And not just during the middle school years; your teeth shift from original position throughout your life.

It can be unnerving to look in the mirror and see signs that your teeth are shifting. Don’t worry; your dentist is here to help. They can review your case and help you keep your smile looking its best.

Signs your teeth are shifting

Common signs that could indicate shifting teeth include:

Contact your orthodontist if you think you see signs your teeth are shifting.

Why are my teeth shifting?¹

It’s natural to see your smile change and wonder why it’s happening. There are many things that can cause your teeth to shift from original position in your mouth. Some of the most common include:

Natural growth and development
During childhood and adolescence, teeth shift as part of natural growth and development. Shifting can happen when permanent teeth erupt or during a growth spurt. Later in life, teeth may shift as people lose bone density.

Genetics and family history
Inherited traits can increase the likelihood of certain dental conditions, including tooth shifting.

Trauma or injury to the mouth
Accidents, falls, and injuries can cause teeth to shift from their original positions.

Poor oral habits or oral hygiene
Habits such as thumb-sucking, tongue thrusting, or prolonged pacifier use can exert pressure on the teeth and contribute to shifting. Additionally, inadequate oral hygiene practices can lead to gum disease or tooth loss, which can cause neighboring teeth to shift.

Tooth loss or extraction
When a tooth is lost or taken out, the teeth around it can move to fill the empty space. This movement can make your teeth appear crooked or cause them to not line up properly.

Grinding Teeth
The constant pressure and rubbing when you clench or grind your teeth can slowly push them out of their proper positions, causing them to shift. Over time, this can lead to crooked teeth or a misaligned bite.

Speak to your doctor²
Seek professional dental care if you're concerned your teeth are shifting. Your dentist or orthodontist can evaluate your teeth and determine if there is an issue and recommend appropriate treatment options. Sometimes, they may recommend orthodontic treatment, such as traditional braces or Invisalign^® clear aligners. Use the Invisalign Doctor Locator to find an orthodontist near you.

Remember your retainer³
Retainers are appliances that may help you deal with shifting teeth. Retainers prevent teeth from gradually returning to their initial position after orthodontic treatment. For example, seeing your teeth move back after completing treatment with braces or Invisalign treatment might mean you’re not wearing your retainer as recommended.

Take great care of your teeth.
Maintaining good oral hygiene is crucial for preventing dental issues and supporting the effectiveness of orthodontic treatment.

Brush your teeth at least twice daily. Use a soft-bristled toothbrush and fluoride toothpaste when brushing. Floss at least once per day to remove plaque from your teeth. You may also want to consider cleaning aids like dental floss picks, interdental brushes, or water flossers.

Watch your diet⁵
Your diet can influence the health and stability of your teeth . Adopting a balanced diet that promotes good oral health can help prevent further dental issues and support the effectiveness of orthodontic treatment. Limit consumption of sugary and acidic foods and beverages, as they can contribute to tooth decay and erosion. Incorporate tooth-friendly foods into your diet, such as fruits, vegetables, lean proteins, and dairy products. These foods provide essential nutrients for maintaining strong teeth and gums.

What not to do when teeth start shifting

It’s possible that some actions or habits can make teeth shifting worse. Talk to your dentist if you're doing any of these items listed below:

Ignoring the problem or avoiding treatment
Ignoring shifting teeth can make misalignment worse. Address any issues you see promptly with your dentist. Don't delay dental appointments or check-ups. Keep up with follow-up visits so your doctor can monitor progress of any orthodontic treatment and address any emerging concerns.

Trying DIY or at-home remedies without professional guidance.⁶
Self-diagnosing and self-treating your shifting teeth can be risky. Avoid applying excessive force or pressure to your teeth using DIY braces or aligners. Only attempt to straighten your teeth with professional guidance from an orthodontist or dentist.

Forgetting oral hygiene.
Good oral hygiene is crucial, especially when dealing with shifting teeth. Failing to brush and floss regularly can contribute to dental issues like gum disease and tooth decay, and possibly make teeth shifting worse.

Not breaking bad habits.
Certain habits can contribute to teeth shifting and should be avoided. These habits include thumb-sucking, tongue thrusting, biting on hard objects, and clenching or grinding your teeth.

Not wearing your retainer.⁷
Following your dentist's instructions after treatment with braces or Invisalign treatment is critical. Skipping or neglecting to wear your retainer can allow your teeth to return to their previous positions.
