A straighter smile can improve more than just your appearance it can also make teeth easier to clean, improve your bite, and support long-term oral health. If you're considering orthodontic treatment, one of the biggest decisions you'll face is whether to choose Invisalign® or traditional fixed braces. Both options are highly effective, but they work differently and suit different lifestyles, treatment needs, and personal preferences. Understanding the advantages of each can help you make an informed decision with guidance from your dentist or orthodontist. How Does Invisalign Work? Invisalign uses a series of custom-made, clear plastic aligners to gradually move your teeth into their planned positions. Each aligner is worn for around one to two weeks before progressing to the next in the series. Patients considering Invisalign Bristol often appreciate that the aligners are virtually invisible and can be removed for eating, brushing, and flossing. Invisalign may be suitable for treating: Crowded teeth Gaps between teeth Mild to moderate bite issues Relapse following previous orthodontic treatment Success depends on wearing the aligners for the recommended number of hours each day.
