Erosion is a common issue when it comes to treatment with Invisalign. The plastic aligners cover the teeth for almost 24 hours a day, which can lead to a lack of oxygen and saliva that are essential for dental health. If acidic ingredients are deposited on the teeth while they are covered, the enamel can weaken over time. Invisalign shares this risk with traditional braces, as both can increase the chances of tooth decay and gum disease.
Although the risk is lower with Invisalign due to the removable aligners, the plastic barrier still prevents saliva from reaching the teeth and gums. Saliva is beneficial for oral health, as it helps protect against bacteria that cause tooth decay and bacterial buildup that leads to gum disease. Invisalign clear aligners are designed to apply gentle pressure on the teeth to move them into their proper positions. If you notice any of these symptoms worsening when the aligners are in your mouth, stop using them.
