It is not recommended to eat or drink anything while wearing your MTM Clear Aligners, with plain water being the only exception. Colored or sugary drinks can discolor your aligner and even trap tooth-harming substances between the aligner and your teeth which, in serious cases, can lead to decay. Eating food while wearing a clear aligner has a similar effect.
Additionally, it is recommended that patients also remove their MCT Clear Aligners when consuming hot beverages (such as tea and coffee) which run the joint risk of discoloring the orthodontic treatment and warping it from heat.
