It started around 4 am and not bad, only aware of it if I swallow or when eating, feels like it is scratched, not soar - first day wearing aligners yesterday, could this be the reason? Hopefully it is not viral... I have been so extremely careful these months and now I am freaking out a bit. Have only gone out for essentials, with mask and gloves. And dentist (last month for cleaning and yesterday to put in aligners) should be safe, they are taking a thousand precautions... sorry, just hoping someone can reassure me. Thanks.
