Hello This yellow lining is stains,do brushimg twice daily

Hi, yellow lining (tartar) will build up around the teeth when brushing is not done with the correct technique. I can understand your problem, though brushing twice a day you still observe that lining it might be because that tartar would have been hardened before you started cleaning effectively. Once tartar is hardened, how effectively we brush also we can't remove that lining.

Please visit a dentist or get an online consult for correct tooth brushing technique. This seems to be dental plaque indicative of incorrect brushing technique

Learn proper brushing techniques from your dental surgeon.
