Should I be worried and can I get a decay under composite if tiny pieces of food went inside? (Photos)

Hi. Composite is a material that, if it is not maintained, can filter food and generate cavities. Maybe when they installed your veneers they didn´t polish enough.  there is a porosity where the food is filtered and these spots appear. You must go to the dentist to polish to avoid cavities

Hello!Well the one in the previous part where your thread gets stuck if you go with your dentist because it ends up falling or getting food, maybe it's just very simple and you need to polish. You have very little with them. I do not think it's a big problem.Good luck!
