Clear aligners, such as Invisalign, are becoming increasingly popular as an alternative to traditional braces. However, due to the plastic barrier that covers the teeth almost 24 hours a day, there is a lack of oxygenation and saliva to support the dental structure. This can lead to an increased risk of tooth decay and gum disease. Saliva is essential for protecting teeth against bacteria that cause tooth decay and gum disease.
When aligners are used for a long period of time, they can affect gum health and cause periodontitis and gingivitis. A study conducted with aligners reported that they can cause tooth roots to weaken, leading to slow resorption of dental roots. The main mechanism through which clear aligners work is similar to dental appliances, in which the teeth move slowly over a period of time. If any symptoms worsen when the aligners are in your teeth, it is important to stop using them.
Additionally, any lipstick or lip gloss product will stain on clear plastic aligners, giving teeth a discolored appearance. These liquids can easily penetrate through the aligners and remain on their surface for a longer period, which can cause discoloration of the aligners and even the teeth. Clear aligners should be replaced at regular intervals; however, this is done at the dentist's discretion. In conclusion, clear aligners can weaken enamel if not used properly.
It is important to practice good oral hygiene while wearing them and replace them at regular intervals as recommended by your dentist.
