1. Missing a Tooth? What Happens If You Leave the Gap Alone?

A missing tooth can feel like a small problem, especially if it is not causing pain. But leaving a gap untreated may affect more than your smile. Over time, nearby teeth can shift into the open space, potentially changing your bite and making it harder to keep certain areas clean.
Replacing a missing tooth may help you:
Restore chewing function
Fill an unwanted gap in your smile
Support a more balanced bite
Reduce shifting of neighboring teeth
Replace the visible portion of a missing tooth with a natural-looking restoration

Dental implants are one option for replacing missing teeth. They use an implant post placed in the jawbone to support a replacement tooth.

If you are considering dental implants in Orange County, CA, MacArthur Dental Arts can evaluate your smile and discuss whether implants may be appropriate for your needs. Schedule a consultation to explore your tooth replacement options.
