How to Clean Stained Teeth From Smoking

Updated February 21, 2017

Cigarette smoke tar slowly discolours your teeth, turning them tan or brown in colour. If you have a smoking habit, the most important step to cleaning your stained teeth is to stop smoking. Cleaning will prove fruitless if you continue to expose your teeth to tar contained within the smoke. Set a day to stop smoking and begin treating your teeth to remove the stains and get your pearly whites back.

Brush your teeth with whitening toothpaste when you wake up, after each meal and directly before bed. Use a medium hardness toothbrush to remove plaque effectively without damaging your gums.

Floss after brushing your teeth twice daily. Flossing removes any built-up bacteria from the very edges of your teeth. This prevents the gaps from being darker than the surface of your teeth, bringing attention to the discolouration.

Purchase an at-home teeth-whitening kit from your local grocer, or from your dentist. Follow the package's instructions carefully to begin dramatically whitening your teeth.

Chew a teeth-whitening gum when you are not eating. Chewing gum increases the amount of saliva your mouth produces. Increased saliva production helps remove stains, prevents new stains from forming and fights tooth decay.

Consult with your dentist about getting your teeth professionally cleaned and whitened. Severe stains from smoking will not lift with at-home treatment alone.


Do not use a hard-bristled toothbrush, as you risk damaging your gums and causing infection.
