Other deficiencies that can contribute to tooth discoloration include Vitamin B12 and Vitamin C, which affect plaque buildup and collagen production in gums, respectively.

Teeth can become yellow even with regular brushing and dental care due to factors like aging, genetics, certain medications, excess fluoride, and lifestyle habits such as smoking or consuming staining foods and drinks. Surface stains can often be managed with good oral hygiene, while deeper discoloration from dentin or tartar buildup may require professional treatment. Understanding these causes and adopting preventive habits like limiting stain-causing foods, proper brushing and flossing, and regular dental checkups can help maintain a brighter, healthier smile.

Highlights

Brushing can't remove all the stains because some stains are embedded within the tooth structure and the natural colour of the underlying layer of the tooth is yellowish.

These stain called dentin can be caused be various reasons like aging, certain medications like tetracycline taken during childhood, excessive fluoride use, or any kind of trauma to the tooth. Brushing can only address surface stains and cannot change the inherent colour of the dentin.

Not brushing daily can cause sticky film called plaque to harden into tartar, which strongly adheres to the teeth. The tartar absorbs the colours from food and drinks over time and it becomes impossible to remove with a tooth brush or floss and requires professional dental cleaning.

Simple Ways To Prevent Stains From Getting Worse

Preventing yellow stains from brushing involves a good oral hygiene and lifestyle changes:

Brushing regularly at least twice a day for two minutes using ADA approved fluoride toothpaste. Make sure to reach all the surface of the teeth with soft bristled brush to avoid damaging enamel.
Flossing daily to remove plaque and food particles between the teeth that brushing might miss, and helps prevent staining and decay.
Rinsing the mouth immediately after eating and drinking stain causing items.
Using whitening products with caution helps in removing surface stains. For deeper stains, consult the dentist about professional treatments.

Some Habits That Prevent Yellow Teeth

Reduce consuming items like coffee, tea, red wine, juice, colas as they cause staining.

Using a straw before consuming acidic and dark coloured beverages to minimize the direct contact with the front surface of the teeth.
Quit smoking and tobacco use as it is the major cause of stubborn brown and yellow stains. Quitting this habit is the best ways to prevent worsening and discoloration.
