Drinking alcohol or sugary drinks won’t damage your aligners, but it would leave your teeth surrounded by liquids that cause tooth decay. If you clean your teeth and your aligners right after drinking alcohol or sugary drinks, you’ll be OK. Our Carmichael dental office would like to remind you that the drink that will keep your teeth their healthiest while wearing your Invisalign trays is plain water. Some people have found that wearing the Invisalign system has greatly improved their diet, because it makes them more aware to not snack or sip unhealthy foods and drinks throughout the day. So while your teeth are improving, you may see some good results on your bathroom scale too!
