Thanks so much!!! I probably have iron deficiency since I have had it in the past. I never even considered that. Thanks again!

Hi! Iron deficiency and Vit B6 or pyridoxine deficiency and Vit B12 deficiency may be associated with a cracked tongue. The other possibility is allergy to some food preservative or to propylene glycol which is found in some food items, drugs and cosmetics. Maybe your dental paste has it. Check this out.
Other possibilities are aphthous ulcers, oral lichen planus, erythema multiform, pemphigus vulgaris, syphilis, yeast infection; exposure to irritants such as hot foods, or spices, tobacco, alcohol; allergy to toothpaste, mouthwash, breath fresheners, dyes in candy, dentures, food items, coloring agents, or blood pressure medications like ACE inhibitors. It could also be a mechanical irritation by a jagged tooth edge or a denture.
I think you should discuss these possibilities with your doctor. It is difficult to comment beyond this without examining. A comprehensive investigation is required keeping all the points in mind. Take care!
