A dentist or general physician can diagnose geographic tongue by examining your tongue and symptoms.
During the examination, your doctor may do the following:
- Check your tongue and mouth with the help of a lighted instrument
- Look for abnormal changes or tenderness in texture or consistency of the tongue
- Check for symptoms of swollen lymph nodes in your neck
Grooved tongue can get treated by itself without any medicines. However, it may make you feel discomfort in the tongue.
To help relieve the discomfort, you can take the following medicines
- Over-the-counter pain relievers
- Mouth rinses with an anesthetic or antihistamine
- Corticosteroid rinses or ointments
- Vitamin B supplements
Since grooved tongue does not need any treatment, it is hard to determine whether these above-mentioned medicines work or not. However, they help you relieve the symptoms.
