Canker sores and lidocaine


I tend to get recurrent canker sores. Each time my doctor prescribes lidocaine. Can this medication cure canker sores?

No, lidocaine is a short acting local anesthetic. It numbs the pain but does not cure canker sores. In fact the pain relief is only for a few seconds. I do not recommend it. You may just apply an ice cube and will get better pain relief. Lidocaine is expensive and a complete waste of money.
