With your query, it would have been better if you had mentioned since when you have thus from birth or recently? If it is from birth then it could be of many reasons like fibrosis or gametogenesis imperfect or ethnogenesis imperfect. If you observe discoloration recently then one must examine the teeth for the cause. With smoking one will get black staining rather than yellow. If you are white then also it is normal because insole fourth they have yellowish color to match their complexion. Hope this helps you. Whatever visit tour dentist for the correct cause.
