What causes stained teeth at 22 despite regular brushing?

Question

Hello doctor,

I am a 22-year-old female and have recently noticed significant discoloration on my teeth, mainly affecting all teeth except my incisors. I do not smoke but drink coffee daily, usually in lattes, not black coffee. I brush my teeth twice a day and occasionally use interdental brushes. Despite this, the discoloration is worsening, and I am starting to feel insecure about it. I am not sure what might be causing it or whether there is anything I can safely try at home to help whiten my teeth. Please advise me on possible causes and any home remedies or treatments I could consider.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern. Coffee can contribute to tooth discoloration, even if it is not black, especially when consumed regularly.

Several other factors that may contribute to your tooth discoloration are

Brushing technique and toothbrush type play a significant role. It is advisable to use a medium-bristled toothbrush and replace it every three months.
Professional dental cleaning every month helps remove tartar deposits and surface stains (yellow or black) through scaling and polishing.
Mouthwash containing Chlorhexidine, if used excessively, can lead to staining.
Liquid iron supplements may also cause black stains on teeth. If you are taking them, it is best to use a straw to minimize contact with your teeth and rinse your mouth with water immediately afterward.
In some individuals, chromogenic bacteria in the mouth can produce dark stains. These are not harmful but require professional cleaning, as home remedies are ineffective.

There are no reliable home treatments for these types of stains. A professional dental cleaning session is essential, followed by good oral hygiene practices. You may use a gentle whitening toothpaste once a week, but it is best to do so under your dentist’s recommendation, as overly abrasive pastes can damage tooth enamel.

For best results, follow your dentist’s advice on the frequency of cleaning sessions and maintain consistent oral care at home.

I hope this information helps you.
