Why Do Teeth Turn Yellow? Reasons & Remedies


These Answers are for questions that have posted on Reddit “ Why do teeth turn yellow? Is it possible to brush your teeth every hour to turn them white ?

I am so happy to see too many replies. This indicates that there is a good interest in how to take care of teeth. I wish the following sentences explain some of the confusion as to what makes your teeth yellow, what to brush with, how to brush, and, finally, are veneers worth it, or to go with implants.


Yellow Teeth

Q: Why do teeth turn yellow?

A: There may be a lot of reasons why teeth get very yellow. The outer layer of the teeth is called enamel, approximately 1-1.5mm thick, the hardest tissue in our body. The thickness of the enamel layer thickness changes throughout your life and gets thinner with time. The thinner the enamel, the more yellow teeth show as the second layer of the teeth, called dentin, dominates the last shade. In my practice, we will constantly evaluate the thickness of the enamel layer to know how successful whitening can be. If your enamel gets to be too thin, no whitening products or systems will work. Diet makes your teeth also more yellow. Anything from smoking, coffee, red wine, tea may contribute to staining the teeth. If the thickness of your enamel layer is within normal limits, superficial stains can be cleaned with Prof Teeth Whitening and the result will be great. Think of your enamel as a sponge that has like a rock. The stains will not sneak into the enamel because the structure of enamel is not permeable, and if it does, it will be easily cleaned.

At the same time, there is another patients group with developmental or congenital enamel defects (dentinogenesis imperfecta, amelogenesis imperfecta) or patients with very deep stains caused by medicines (tetracycline stains). In the first situation, the enamel grows to have thickness or structure other than normal & will not whiten. In the second situation, consider the enamel sponge being as hard as a rock and stained all throughout. There is not a great way to soak, and pressure the stain out of the rock hard sponge. The diagnosis is the success and this may clarify some of the horrible stories some of you have mentioned.


Q: How to brush and what to use?

A: This is such a broad post, but I will try to filter it through what has been discussed before on the post of thinning enamel. The enamel layer may get thinner if there are chemicals involved (erosion), if there are mechanical teeth on teeth contact (attrition) or mechanical “bending of enamel” if there is mechanical rubbing of the surface (abrasion) resulting in cracks (abfraction). It is always found that all 3 are present in most patients with a thin enamel layer. Loweres Ph, in another hand, an acidic environment contributes to the quick decalcification of the enamel surface. As enamel becomes decalcified, abrasive forces become too destructive and result in thinning and the loss of the outer layer of teeth. It is a myth that the hard and medium toothbrushes will cause abrasion of enamel. In the mid-2000’s, in the study by Dzakovich, it was discovered that it is not the brush but the tooth paste that is an abrasive tool. Tooth paste contains sand, silica. If you want to prevent enamel abrasion, use a very tiny amount of toothpaste, resort to some old fashion techniques such as soap or use tooth pastes with very fine particles of silica. After all, this is how our ancestors kept their teeth shiny and clean. 



Q: Are Veneers worth it? Or should you just go with Dental Implants?





A: Veneers can be used in some situation when the patient is aesthetic worries about the appearance but has, otherwise, healthy teeth in general. Veneers are not indicated for teeth with a history of large fillings, root canal treatment, or underdeveloped enamel, of teeth with damaged. Veneers are very thin layers made of plastic or ceramic, that are glued onto the surface of a prepared tooth. In many cases, teeth need to be prepared by minimizing the front surface to let for an improved replacement of the enamel layer. In a perfect situation, though quite rare, teeth are tiny to start with and all that needs to be done is to roughen the teeth surface, make enamel replacements, and then bond the veneers in place.
How well veneers stay on the teeth without popping off relies on the bonding of the ceramic veneer to the teeth. Successful bonding relies on the strength of the glue, the type of ceramic, but most importantly, the quality and the amount of enamel left on the tooth. The two main indications of weak veneer performance occur if the enamel is damaged or thin. When this is the case, bonding power may be compromised and then I’d recommend crowns to restore function and form.

I’ll say it again and again, veneers can be a good choice for patients who have aesthetic worries for their generally healthy teeth. Although some persons may consider this a cosmetic remedy, that assumption is not correct. While “cosmetic” indicates to something that may be easy or not important, that is not the case of veneers. Veneers are an aesthetic procedure that requires a technical, scientific approach, and precise in order to be successful. If you are considering veneers, it is strongly recommend that you looking for an experienced prosthodontist that can carefully evaluate whether your teeth are appropriate for veneers. A prosthodontist specializes in implant dentistry, the replacement of teeth, and the aesthetic reconstruction of teeth. Prosthodontists are the only specialists trained in placing on veneers. They are the best bet to feel confident that your beautiful smile was designed with quality and longevity and to obtain the most out of your investment.
