The tip of my tongue is very itchy during the day and a bit red from rubbing against my teeth due to the itchiness, please help?

Tongue-red\itchy: It could be nothing more than a rough or sharp tooth and a habit of rubbing your tongue against the teeth unconsciously. However, it could be quite a number of other things as well. See a dentist to have it evaluated.

See a dentist: for consultation. Some conditions may require further assessment, tests and your dentist may book a follow-up appointment or refer you to a specialist to determine a diagnosis. Take care.
