Teeth shifting in adults is a common occurrence, and not just for those who have had braces at some point in their life. While a clear retainer won't straighten your teeth, using one can help reduce their ability to shift by holding them in place. But what is it that causes teeth to start shifting in the first place? Let's explore a few common culprits of teeth shifting.

Gum Disease

If you suffer from gum disease, you may notice that your teeth have changed alignment. Gum disease causes your gums to pull away from the teeth. Your teeth, in turn, become less secure and start to shift. A clear retainer can help hold everything in place.

Spaces Between Teeth

Many people have extra space between their teeth even after their permanent ones have come in. This additional space can cause teeth shifting with age, usually because of a phenomenon known as Mesial Drift — the teeth's natural tendency to shift toward the front of the mouth. Even the experts are not sure why Mesial Drift happens, but it's likely the cause of most teeth shifting in adults.

Tooth Loss Or Removal

Mesial Drift is behind this form of teeth shifting as well. When a permanent tooth is lost or removed, the teeth behind it tend to shift forward to fill the space. Teeth can begin to shift sideways due to tooth loss as well, so it's important to take proper measures — such as getting a clear retainer — to ensure your teeth stay in their current positions.

Teeth Grinding

Teeth grinding or Bruxism can push your teeth out of alignment over time. The pressure of your lower jaw against your upper teeth gradually shoves your teeth out of place and can also lead to increased sensitivity, headaches, and even broken teeth. Teeth grinding is a serious issue that you should talk with your dentist about, especially if you're noticing any of the symptoms mentioned above. One solution your dentist may recommend is a night guard for your teeth. A clear retainer may help guard against teeth grinding as well.


Having a cavity filled can alter the shape of your tooth, which can, in turn, cause a change in your bite. You other teeth may shift to accomodate the new size and shape of the altered tooth. A clear retainer will help prevent teeth shifting despite these changes.


Some people experience teeth shifting with age simply because it runs in their family. If your family members have experienced teeth shifting later in life, you may want to invest in a clear retainer to help keep everything in place.

Normal Wear

Teeth shifting in adults is often caused by the gradual aging of teeth, often from a natural reduction of enamel. This particularly affects the lower teeth, which can shift because they're less able to withstand the force of the upper teeth biting down on them. A lower clear retainer can help prevent these shifts from occurring.
