Hello doctor, I have two sores on my tongue. The sores have a clear to yellow pus like covering on them. What can it be? Please advise.
Hello. Sores can heal better by avoiding acidic or highly salty foods and any other substances that are irritating. An anesthetic such as Lidocaine may be used as a mouth rinse. Sucralfate and Aluminum-magnesium antacids can be soothing when applied alone.  Some mouth sores can be treated with a low-powered laser, which relieves pain immediately and prevents sores from returning. Chemically burning the sore with a small stick coated with silver nitrate may similarly relieve pain but is not as effective as a laser. Also, advise you to do warm salt water rinses to keep the infection at bay.
