[|Human|] Dear Dr., I have a 21 months old son who has a sore tongue. The sore on the tongue normally comes up and gets cured naturally, and comes up again on different location on the tongue and dries up, and continues. His tongue normally smells when sores. Please advice on this. Regards, Andrew
[|AI|]  Hi. Welcome to Chat Doctor. As per your complaint recurring sores on tongue of your child can be due to causes like Recurring Authors Dermatitis or Recurring Authors Ulcers while can also be due to Viral infection causing Herpetic Cold Sores. I would suggest you to consult a Periodontist and get him evaluated especially when sores are present and get a blood test and oral swab culture done, and then a proper treatment can be advised. As of now you can give him supportive treatment like doing cool compresses over the tongue, feeding with plenty of cool fluids' ad give him a soft and bland diet. He can also be advised numbing gels like Xylocaine gel to be applied in small amounts precisely over the ulcers. Hope this helps.
