I used activated charcoal straight for about a week to whiten my teeth.   My mouth is weird feeling.   Not exactly sure where the numbness is.  Front upper and lower gums .  Lips have been swollen, they are better now.  My  mouth feels as it would if it had been numbed.  Wondering how long this will last.  I have not used charcoal for 3 days now. Thank you,Rona
Hello, Thanks for writing to us.First, let me advise you not to use abrasive agents like charcoal to whiten teeth. Always take an opinion by your dentist prior to using such agents. Apply anesthetic gel on the affected site. Use soft bristled toothbrush as well as desensitizing toothpaste to clean your teeth. Gargle with chlorhexidine mouth rinses too. Swish with warm saline until the swelling subsides. Hope this helps.
