Hi
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 flurosis or amelogenesis imperfecta or dentinogenesis imperfecta. If you observe discoloration recently then one must examine the teeth for the cause.with smokin one will get black staining rather than yellow. If you are white then also it is normal coz insole byburth they have yellowish color to match their complexion. Hope this helps you. Whatever visit tour dentist for the correct cause.

Hello,
I have read your inquiry. Reasons teeth can appear yellow:
-Stain, coating on surface of teeth
-Stain, pigment into tubules of teeth
-Plaque and tartar buildup surrounding teeth
-wearing of enamel, thinning
-Decay, breakdown of enamel structure
-Abrasion, wearing into the tooth near root
-Recession, exposue of darker root structure
-Weakness to enamel such as decalcificatiob, mottling
-infections in your mouth

You can try various dental products with good daily home dental hygiene. Whitening products include a peroxide based ingredient that has a whitening effect. Make sure you are following proper techniques with brushing with a soft brush, flossing and rinsing daily. Take home whitening kits include strips and gel with trays systems. Oil Pulling is another popular technique that you can do at home. This includes is swishing for 20 minutes with 1-2 teaspoons of coconut oil in the morning before breakfast. Spit out thick and milky oil. Rinse afterwards with warm water. This method uses natural products to cleanse and detoxify your mouth. The concept is that this method removes bacteria from the mouth. This is a home remedy for you to try.
Your diet and habits will affect staining. You can limit foods and liquids known to stain. This includes coffee, tea, berries, and smoking.

I recommend regular dental exams and cleanings. Tartar is a hard substance that requires sharp tools to scape it away from your teeth by a dental professional. Bonding and other restorative techniques can be utlized to replace missing tooth structure caused by decay or missing enamel by your dentist. Changes to your gums may require periodontal treatment such as grafting to bring the tissue back over the root. In office professional whitening will use stronger products and usually produce a whiter result. Other dental conditions will be evaluated with a dental exam.

I suggest that you find a dentist you are comfortable with and start with a basic visit. Keep up with routine dental cleanings. You make the decision on what additional treatment you want from your dentist. You want to understand if you have any dental infections that can cause coatings and color changes to your teeth or be detrimental to your overall health.

Thank you for your inquiry. I hope you find my suggestions helpful. I am available to answer additional questions.
