One of the downsides of Invisalign is that it can increase your risk of developing gum disease and tooth decay. Having the plastic trays snug against your teeth makes it difficult for saliva to reach your teeth and gums, where it helps to harden enamel and wash away plaque and bacteria. Some people who wear Invisalign do experience enamel erosion, but the main reason for this is poor oral hygiene. With Invisalign, keeping your teeth and aligners clean is an important factor in preventing enamel erosion. Your orthodontist will give you a clear set of instructions to follow, and it’s important to adhere to them as best you can. Some key strategies your orthodontist may recommend during your Invisalign treatment include:
● Brush and floss your teeth after every meal
● Rinse your mouth vigorously after eating if you do not have a toothbrush or floss handy
● Always rinse your mouth before replacing your aligner tray
● Never eat or drink anything but water while wearing your aligner trays
● Avoid acidic foods and beverages as much as possible
● Use fluoride toothpaste or other orthodontist-recommended products
● Visit your dentist and orthodontist regularly
While it’s true that enamel erosion can happen with Invisalign treatment, it’s also preventable—as long as you’re consistent and thorough with your oral hygiene routine.
