Please attach some clear photographs of effected area. If their are yellow deposit on tooth, then you need scaling of teeth. But if they are naturally yellow in color then you can go for scaling and bleaching of teeth.
Sensitivity to cold could be due to carious or chipping off of superficial layers of tooth. Need to check completely to guide properly.
Consult doctor online or offline for better guidance and treatment options.
