Stained teeth: causes and treatment
Find out what causes stained teeth and treatment options
Want white teeth? Welcome to the club! Studies show that in most countries, the popularity of teeth whitening is surging - particularly among those aged under 35.
If the proliferation of bright, white smiles on social media is causing you to take a closer look at your own teeth, and you’re noticing they’re more yellow-ish than pearly white, teeth whitening could be an option for you. But before you go down that path, finding out what has caused teeth staining, and how to treat it, would be a great place to start.
We hit up Clear Dental's Dr Johnson Huang to talk teeth-staining truths.
What causes stained and yellow teeth?
Short answer? A lot!
“The most common causes of stained teeth I see are poor dental hygiene and drinks like coffee, tea and wine,” Johnson says. “And in elderly patients, certain medications can cause discolouration too.”
Most causes fall into one of two distinct categories – stains caused by lifestyle habits and those resulting from poor dental health.
Lifestyle habits that cause stained teeth
Foods and drinks – coffee, tea, colas, wine and some starchy foods such as pasta or potatoes
Tobacco (chewing or smoking)
Poor dental health habits that cause stained teeth
Not flossing or brushing your teeth
Diseases and certain medical treatments, such as radiation and chemotherapy
Ageing – the white outer layer of teeth gets worn away as we age
An excess of fluoride
Trauma – such as sports injuries
Preventing teeth staining
There are three main ways to prevent your teeth from taking on an unappealing yellow tinge:
Keep up great oral health habits – that means flossing your teeth every day and brushing both morning and night
Cut back on tooth-staining foods (think: tea, coffee, red wine). And if you do partake, make a point of brushing and flossing, or at least swishing some water around your mouth, after you’ve eaten them
Quit smoking – contact Quitline if you need support
Ways to treat stained and yellow teeth
OK, so you have stained and yellow teeth, now what? Great news – in many cases, reversing teeth stains is possible.
Consulting with a dentist is key – and not just for cosmetic reasons. A dentist can tailor a treatment plan to the cause of staining, and any underlying problems will be ruled out too.
“Even though the condition doesn’t cause any immediate harm or symptoms, ongoing stained teeth can be a warning signal of oral dental deterioration,” Johnson explains.
Your dentist can often remove superficial stains using tools like ultrasonic scalers and prophy jets, says Johnson. And if they’re deeper than that, peroxide-based whitening systems such as Zoom and Pola White might be the best approach. While there are plenty of at-home whitening options out there, there are risks involved in using them. The safest way to whiten teeth is by visiting your dentist, says the Australian Dental Association.
“In rare cases, however, whitening doesn’t work,” Johnson adds. “In these cases, dental veneers can be a very good alternative to discoloured teeth.”
