Ingesting charcoal has long been used to help relieve gas and other digestive problems. Nowadays, activated charcoal, a form of charcoal that’s been finely processed into a powder, is used on people who have ingested certain deadly poisons or drugs, since the charcoal stops the poison from reaching the bloodstream through the gut.
Activated charcoal itself may be too abrasive for using to brush your teeth daily, as it actually wears away the enamel. What’s more, the dark charcoal paste can leave the teeth looking grey and dull if it isn’t completely brushed off. The extra scrubbing needed to get rid of it completely could cause extra wear and tear on the enamel. Charcoal particles can also get caught up in the gums and irritate the gums.
The charcoal products which are increasingly popular often contain no fluoride to help protect the teeth. And there is no scientific evidence to back up the claims that they whiten and brighten your teeth. Excessive brushing with them can actually do more harm than good.
It’s therefore advisable to go see your dental professional for advice on cleaning and/or whitening teeth. Concerns about staining or discolored teeth might be solved by a change in diet and improvements in oral hygiene.
So, your best bet is to do your dental checkups and cleanings regularly and quit smoking or any other habits that can stain teeth. Also, use regular toothpaste with fluoride as well as floss or interdental brushes to maintain good oral hygiene, hence a bright healthy smile.
