How to get the yellow stains off your teeth
Yellow tooth stains may be surface plaque and calculus or natural dentin showing through enamel, so the correct treatment depends on the cause.
The short answer
A dental cleaning can remove yellow surface deposits, while yellow colour from dentin or intrinsic discoloration requires a diagnosis before whitening.
What is the direct answer?
What does this question mean?
Enamel is naturally translucent, allowing the yellow-brown dentin beneath it to influence tooth colour. Plaque can harden into calculus and collect pigments from drinks or tobacco on the enamel surface; erosion and thinning enamel can make the underlying dentin more visible.
What can you do next?
Brush with fluoride toothpaste, clean between teeth, and arrange professional removal of calculus. Limit frequent pigment exposure, rinse after acidic drinks, and avoid lemon, charcoal, or abrasive scrubbing that can wear enamel.
When should you seek dental care?
See a dentist or hygienist when the colour change is new, concentrated around the gum line, limited to one tooth, or associated with bleeding, sensitivity, pain, or a rough deposit.
What should you ask the dentist?
Is the yellow appearance caused by removable calculus, enamel wear, natural dentin, or an internal change in the tooth?
Frequently asked questions
Will whitening remove calculus?
No. Calculus must be removed mechanically before whitening is considered.
Why are the necks of my teeth yellow?
Gum recession or thinner enamel near the gum line can expose or reveal yellow dentin.
