Braces are a common and effective way to straighten teeth, fix bites, and improve overall oral health. If you’re considering braces, here’s what you need to know. Braces are dental devices used to correct teeth that are crooked or misaligned. They apply gentle pressure to the teeth over time, gradually moving them into the desired position. Braces can also help fix bite issues, making it easier to chew and speak properly.
