Could using listerine mouth wash cause numbness in tongue?
Patient: My son has used Listerine mouthwash for some time.  Recently, after using it, his tongue went numb.  He needed to have his wisdom teeth pulled & thought it might be from that.  The oral surgeon just pulled his wisdom teeth & said the nerve to the tongue is not associated with the nerve to the wisdom teeth.  They are putting him on a steroid.  They said Listerine may have caused it.  Is that possible? Doctor: Hello,  Read your query, as your son had undergone wisdom tooth extraction this paraesthesia of tongue can be due to lingual nerve injury during anaesthesia given or it can be due to use of mouthwash also dont be worried so much you should consult dentist and discuss to take mrdication like one tablet Neurobion for numbness, discontinue your mouthwash . Do warm saline gargle two - three times a day,  take proper nutritious healthy diet , green leafy vegetables , take proper sleep of 8 hours. Hope it will help you. If you have further query I will be happy to help. Wishing him good health .Regards,  Dr. Priyanka tiwari
