Brushing every day is important — but if your teeth still look yellow despite good habits, you’re not alone.
Many patients feel frustrated when their smile doesn’t match their efforts. The truth is: yellow teeth are caused by many factors beyond just brushing.
At Align & Smile Dental Care, Sector 18, Noida, we help you understand the real reasons behind tooth discoloration and what you can do to fix it effectively.
✔ 1. You May Have Stubborn External Stains
These stains stick to the outside layer of teeth (enamel).
Common causes include:
Tea, coffee & cold drinks
Turmeric / coloured foods
Smoking or vaping
Wine
Poor brushing technique
🧽 Solution: Professional scaling & polishing removes deep, hardened stains your toothbrush can’t touch.
✔ 2. Your Enamel Is Thinning
As enamel gets thinner (age, genetics, acidic diet), the inner layer (dentin) becomes more visible — and dentin is naturally yellow.
🧼 Brushing harder doesn’t help — it actually makes enamel thinner!
🧪 Solution: Fluoride care, remineralisation treatments, and avoiding acidic foods.
✔ 3. You Have Internal (Intrinsic) Stains
These are deeper stains inside the tooth, caused by:
Childhood medication (tetracycline)
Trauma (injury to tooth)
Tooth decay
Birth conditions
Excess fluoride in early years
🦷 Solution: Teeth whitening, veneers, internal bleaching (depending on the cause).
✔ 4. Incorrect Brushing Technique
You brush daily — but:
Are you brushing for full 2 minutes?
Are you reaching all surfaces?
Are you brushing too hard? (Causes more yellowing!)
🦷 Solution: Soft-bristle brush + gentle circular strokes + twice daily brushing.
✔ 5. You’re Brushing but Not Cleaning Enough
Skipping these allows stains to stay:
Not flossing
Not cleaning tongue
Skipping regular dental cleaning
🧵 Solution: Floss daily + tongue cleaning + a professional dental cleaning every 6 months.
✔ 6. Your Diet Is Constantly Re-Staining Your Teeth
Even with brushing, if you consume:
Coffee/tea multiple times daily
Colas
Spicy Indian curries (turmeric)
Berries
Beetroot
…your teeth re-stain quickly.
🧪 Solution: Rinse after meals, use a straw for drinks, opt for whitening-friendly foods.
